* Spotting Uneven Floors and Doors/Windows That Stick

* Understanding Concrete Floor Cracks: A Homeowner's Perspective.


Okay, so you're walking through your house, maybe grabbing a snack or heading to the couch, and *bam*, there it is. Moisture levels should be monitored to prevent future foundation issues foundation repair expert service steel. A crack. In your concrete floor. Not a good feeling, right? It's easy to panic and imagine your house crumbling around you, but before you start selling the furniture, let's talk about understanding those cracks from a homeowner's point of view.

The thing is, concrete isn't some indestructible magical substance. It's going to move. It's going to settle. And sometimes, that movement shows up as cracks. Recognizing them is the first step. We're not talking about hairline fractures; those are pretty common and often just cosmetic. We're talking about actual cracks, maybe ones you can feel with your toe, or ones that seem to be getting wider.

And it's not just the cracks themselves, but also any shifts or unevenness in the floor. Is one section of the floor suddenly higher or lower than the rest? Are you noticing a new slope where there wasn't one before? These shifts can be even more concerning than the cracks themselves, as they can indicate more significant movement in the foundation.

Think about where the cracks are. Are they near a wall? Running across the middle of a room? The location can offer clues about the cause. Cracks near walls can be related to settling of the foundation, while those in the middle might be from shrinkage during the curing process or heavy loads.

So, what's the point of recognizing all this? It's about being informed. It's about understanding the difference between something that's probably normal and something that might need a professional's attention. Because let's face it, as homeowners, we need to be proactive. Spotting potential problems early can save us a lot of headaches (and money) down the road. Seeing a crack doesn't automatically mean disaster, but recognizing it, understanding its characteristics, and then deciding whether it warrants further investigation is all part of responsible homeownership.

* Types of Cracks Requiring Professional Residential Foundation Repair.


Okay, so you're walking around your house, maybe doing some spring cleaning, and you glance down at your concrete floor. And…crap. A crack. Or maybe a whole bunch of them. Before you panic and start budgeting for a new house, let's talk about which cracks actually scream "call a foundation expert, like, yesterday" and which ones are just kinda...meh.

Think of it like this: concrete is tough, but it's not invincible. It expands and contracts with the weather, and your house is constantly settling. Hairline cracks, the super-tiny, barely-there ones? Those are usually just cosmetic. They're annoying, sure, but they generally don't mean your house is about to crumble. You can often fill those in yourself with some concrete crack filler.

But then there are the cracks that are red flags. Big, honking, "oh no" cracks. We're talking about cracks that are wider than, say, a quarter of an inch. Especially if they're uneven, meaning one side of the crack is higher than the other. That's a sign of differential settling, where different parts of your foundation are sinking at different rates. Not good.

Another type to watch out for are cracks that run diagonally across your floor. These often indicate structural movement and can be related to foundation issues. Also, pay attention to cracks that are getting bigger over time. Put a pencil mark at the end of the crack and date it. Check back in a few weeks or months. If the crack has extended past your mark, that's a sign it's actively growing and likely needs professional attention.

Finally, and this is a big one, if you see cracks in your concrete floor *combined* with other issues, like doors or windows that are sticking, walls that are noticeably bowed, or even just a general feeling that the house isn't quite "square" anymore, then you absolutely need to call a foundation specialist. These are all clues that point to a larger, underlying problem with your foundation.

Bottom line? A few hairline cracks? Probably okay. Large, uneven, growing, diagonal cracks, especially when paired with other structural oddities? Time to get a professional opinion. It's better to be safe than sorry when it comes to your home's foundation. Ignoring a serious issue can lead to much bigger (and much more expensive) problems down the road.

* Identifying Shifts and Unevenness in Concrete Floors.


Hey, so you're trying to figure out what's up with your concrete floor, huh? Specifically, you're looking at cracks and, more worryingly, shifts and unevenness. Let's talk about those shifts and uneven spots – they're a bit more concerning than a simple hairline crack, and here's why.

Think of it like this: a small crack might just be the concrete flexing its muscles a bit, settling over time. But a shift or unevenness? That's like the muscle tearing, or the whole foundation groaning. It suggests something more substantial is going on underneath.

Identifying these shifts isn't always easy. Sometimes it's obvious – you stub your toe on a raised edge, or you see a clear dip in the floor. Other times, it's more subtle. You might notice furniture rocking slightly, even though the legs are level. Or maybe a door that used to swing freely now catches on the floor. A marble or ball rolling in a direction it shouldn't is a good, low-tech way to spot subtle slopes.

Unevenness can also show up as changes in the height of the floor relative to walls or other structures. Is the floor suddenly higher or lower than the baseboard in a certain area? That's a red flag.

What causes this stuff? Well, it's usually about what's happening beneath the concrete. Soil shifting, settling, or even being washed away can lead to these problems. Poor drainage, tree roots, or just the natural compacting of the earth over decades can all play a role. Sometimes, it's related to the original construction – maybe the soil wasn't properly compacted before the concrete was poured.

The important thing is that if you spot these shifts and uneven areas, don't ignore them. While a small crack might be cosmetic, unevenness often points to a structural issue that could worsen over time. It's a good idea to get a professional to take a look and figure out the underlying cause. Ignoring it could lead to bigger problems down the road, and that's definitely something you want to avoid.

* Potential Causes of Concrete Floor Damage in Residential Settings.


Recognizing Cracks and Shifts in Concrete Floors: Potential Causes of Concrete Floor Damage in Residential Settings

You're walking across your living room, maybe barefoot, and suddenly you feel it – a slight dip, a hairline fracture under your toe. Or perhaps you glance down and notice a crack snaking its way across the concrete slab. These aren't just cosmetic issues; they're whispers, subtle clues that something might be amiss beneath the surface. Before you panic and start envisioning a total foundation collapse, let's explore some potential causes of concrete floor damage in residential settings. Understanding these culprits can help you assess the severity of the problem and determine the best course of action.

One of the most common offenders is simple settling. Our homes, even relatively new ones, are constantly adjusting to the earth beneath them. Soil compacts, shifts due to water content changes, and this movement can exert pressure on the concrete slab. Hairline cracks, often appearing shortly after construction, are frequently the result of this natural settling process. While usually not structurally significant, monitoring them for widening is crucial.

Speaking of water, it plays a significant, often destructive, role. Excessive moisture in the soil can lead to expansion and contraction, putting stress on the concrete. Poor drainage around the foundation, leaky pipes, or even just consistently heavy rainfall can all contribute to this problem. Conversely, extremely dry conditions can cause the soil to shrink, creating voids beneath the slab and leading to cracking and unevenness.

Then there's the matter of the concrete mix itself. If the original mixture was improperly proportioned – too much water, insufficient cement, or the wrong type of aggregate – the resulting slab may be inherently weaker and more prone to cracking. Similarly, inadequate curing during the initial setting process can compromise the concrete's strength and durability.

Finally, consider the loads placed upon the floor. While a residential concrete slab is designed to withstand a reasonable amount of weight, excessive point loads – think of a heavily loaded bookshelf concentrated on a small area – can exceed its capacity and lead to localized cracking or sinking. Similarly, significant vibrations from nearby construction or heavy machinery can also contribute to damage over time.

Recognizing cracks and shifts is the first step. By understanding these potential causes, you can start to piece together the puzzle and determine whether the issue is a minor cosmetic flaw or a sign of a more serious underlying problem that requires professional attention. Don't ignore those whispers from your floor; they might be telling you something important.

* When to Contact a Foundation Repair Specialist: Red Flags.


Okay, so you're strolling through your house, maybe barefoot, maybe just admiring your handiwork (or lack thereof), and you notice something...off. That perfectly smooth concrete floor you remember seems to have sprouted a crack. Or maybe that gentle slope you always attributed to your imagination is, well, still there, but maybe a little *more* there. That's when the little alarm bells in your head should start to tingle.

Recognizing cracks and shifts in your concrete floor is like deciphering a secret code your house is trying to tell you. Not all cracks are created equal. Hairline cracks, those tiny little guys that look like someone drew on the floor with a very fine pencil, are usually just cosmetic. They happen as the concrete cures and shrinks, and most of the time, you can fill 'em and forget 'em.

But. Big but here. If you're seeing cracks that are wider than, say, a quarter of an inch, or if they're jagged, or if they're accompanied by one side of the crack being higher than the other (that's the "shift" part we're talking about), then Houston, we might have a problem.

Think of it like this: your concrete floor isn't just sitting there. It's the foundation for everything else. If it's cracking and shifting, it suggests the ground underneath is moving, settling unevenly, or experiencing some kind of pressure it wasn't designed to handle. That could be due to poor drainage, expansive soil, or, worst case scenario, a foundation problem brewing.

Ignoring these bigger, more noticeable cracks is like ignoring a toothache. It might start as a little twinge, but left untreated, it can turn into a root canal nightmare. The same goes for your foundation. A small crack now could lead to major structural issues down the road, costing you a whole lot more time, money, and stress. So, those red flags? Those are your house's way of saying, "Hey, it's time to call in the professionals." Don't ignore them. Your wallet (and your house) will thank you.

* The Role of Soil and Drainage in Concrete Floor Stability.


Okay, so you're checking out your concrete floor and you see a crack. Or maybe the whole thing looks like it's shifted a bit. Before you panic about a major structural disaster, let's talk about what might be going on beneath the surface, literally. I'm talking about the soil underneath and how well your floor is draining. Because believe it or not, those two things play a HUGE role in whether your concrete floor stays put or starts acting up.

Think of your concrete slab as a boat. That boat needs stable water to float on, right? Well, the soil is that "water." If the soil is uneven, poorly compacted, or just plain unstable, your concrete floor is going to feel it. Imagine building a house on sand – it's going to shift and settle. The same principle applies here. Soil that expands and contracts with moisture changes can put a ton of stress on the concrete. Clay soils are notorious for this. They swell when wet and shrink when dry, leading to cracks and movement in the slab above. Proper soil preparation, including compaction and sometimes even soil replacement, is crucial *before* the concrete is ever poured.

Then there's drainage. Picture this: you've got water constantly pooling around the foundation of your house. That water eventually seeps into the soil, saturating it. This saturation can weaken the soil's supporting capacity and, again, lead to movement. Poor drainage can also cause hydrostatic pressure, which is basically water pushing upwards on the underside of the slab. Over time, this pressure can crack the concrete or even lift sections of it. Gutters that aren't diverting water properly, landscaping that slopes towards the foundation, or even just poor grading around the house can all contribute to drainage problems.

So, when you're looking at those cracks and shifts, don't just focus on the concrete itself. Take a look around. Is there standing water near the foundation after it rains? Is the ground sloping towards the house? Are your gutters clean and functioning? These are all clues that can help you figure out if the soil and drainage are the culprits behind your concrete woes. Addressing these underlying issues is often the key to preventing further damage and ensuring the long-term stability of your concrete floor. Ignoring them is like trying to patch a leaky boat without fixing the hole – it's just a temporary fix that won't solve the real problem.

* Foundation Repair Solutions for Cracked or Shifting Concrete Floors.


Okay, so you've got cracks in your concrete floor, maybe even some shifting going on. That sinking feeling in your stomach? I get it. It's not just about aesthetics; it's about the stability of your whole house. But before you panic and start picturing your home sliding into the earth, let's talk about recognizing what's going on.

First off, not all cracks are created equal. Think of them like wrinkles – some are just signs of aging, others are a signal something deeper is happening. Hairline cracks, the super thin ones, are pretty common, especially in new concrete as it cures. Usually, they're not a huge concern. But if you see cracks wider than, say, an eighth of an inch, or if they're jagged and uneven, that's when you need to pay closer attention.

Then there's the shifting. Does a door suddenly stick? Are windows harder to open or close? Look at where the floor meets the walls. Are there gaps that weren't there before? These are all clues that your foundation might be moving. Sometimes, it's subtle; other times, it's pretty obvious – a noticeable slope in the floor, for example.

Don't just rely on your eyes, though. Feel the floor. Is there a dip in one area compared to another? Get down on your hands and knees (yes, really!) and shine a flashlight across the surface. This will highlight any unevenness you might miss standing up.

And finally, keep an eye on things over time. Take pictures of the cracks. Measure the width of the cracks if you can. Note any changes in the shifting. This will give you a baseline and help you track whether the problem is getting worse.

Recognizing these signs early is key. The sooner you address foundation issues, the better the chances of finding a cost-effective repair solution and preventing further damage. So, walk around, take a good look, and trust your gut. If something feels off, it probably is.



A disaster inspector at work in the United States assessing tornado damage to a house

A home inspection is a limited, non-invasive examination of the condition of a home, often in connection with the sale of that home. Home inspections are usually conducted by a home inspector who has the training and certifications to perform such inspections. The inspector prepares and delivers to the client a written report of findings. In general, home inspectors recommend that potential purchasers join them during their onsite visits to provide context for the comments in their written reports. The client then uses the knowledge gained to make informed decisions about their pending real estate purchase. The home inspector describes the condition of the home at the time of inspection but does not guarantee future condition, efficiency, or life expectancy of systems or components.

Sometimes confused with a real estate appraiser, a home inspector determines the condition of a structure, whereas an appraiser determines the value of a property. In the United States, although not all states or municipalities regulate home inspectors, there are various professional associations for home inspectors that provide education, training, and networking opportunities. A professional home inspection is an examination of the current condition of a house. It is not an inspection to verify compliance with appropriate codes; building inspection is a term often used for building code compliance inspections in the United States. A similar but more complicated inspection of commercial buildings is a property condition assessment. Home inspections identify problems but building diagnostics identifies solutions to the found problems and their predicted outcomes. A property inspection is a detailed visual documentation of a property's structures, design, and fixtures. Property Inspection provides a buyer, renter, or other information consumer with valuable insight into the property's conditions prior to purchase. House-hunting can be a difficult task especially when you can't seem to find one that you like. The best way to get things done is to ensure that there is a property inspection before buying a property.

North America

[edit]

In Canada and the United States, a contract to purchase a house may include a contingency that the contract is not valid until the buyer, through a home inspector or other agents, has had an opportunity to verify the condition of the property. In many states and provinces, home inspectors are required to be licensed, but in some states, the profession is not regulated. Typical requirements for obtaining a license are the completion of an approved training course and/or a successful examination by the state's licensing board. Several states and provinces also require inspectors to periodically obtain continuing education credits in order to renew their licenses.[citation needed] Unless specifically advertised as part of the home inspection, items often needed to satisfy mortgage or tile requirements such as termite ("pest") inspections must be obtained separately from licensed and regulated companies.

In May 2001, Massachusetts became the first state to recognize the potential conflict of interest when real estate agents selling a home also refer or recommend the home inspector to the potential buyer.[citation needed] As a result, the real estate licensing law in Massachusetts was amended[1][non-primary source needed] to prohibit listing real estate agents from directly referring home inspectors. The law also prohibits listing agents from giving out a "short" name list of inspectors. The only list that can be given out is the complete list of all licensed home inspectors in the state.

In September 2018, the California state legislature passed Senate Bill 721 (SB 721),[2] which requires buildings with specific conditions, such as having exterior elevated structures, to undergo inspections by licensed professionals. These inspections must be conducted by qualified individuals, such as structural engineering firms,[3] and a detailed report must be issued. Failure to comply with these requirements can result in penalties for property owners.

Ancillary services such as inspections for wood destroying insects, radon testing, septic tank inspections, water quality, mold, (or excessive moisture which may lead to mold), and private well inspections are sometimes part of home inspector's services if duly qualified.

In many provinces and states, home inspection standards are developed and enforced by professional associations, such as, worldwide, the International Association of Certified Home Inspectors (InterNACHI); in the United States, the American Society of Home Inspectors (ASHI), and the National Association of Home Inspectors (NAHI)(No Longer active 10/2017); and, in Canada, the Canadian Association of Home and Property Inspectors (CAHPI), the Professional Home & Property Inspectors of Canada (PHPIC) and the National Home Inspector Certification Council (NHICC).

Currently, more than thirty U.S. states regulate the home inspection industry in some form.

Canada saw a deviation from this model when in 2016 an association-independent home inspection standard was completed. This was developed in partnership with industry professionals, consumer advocates, and technical experts, by the Canadian Standards Association. The CAN/CSA A770-16 Home Inspection Standard was funded by three provincial governments with the intent to be the unifying standard for home inspections carried out within Canada. It is the only home inspection standard that has been endorsed by the Standards Council of Canada.

In Canada, there are provincial associations which focus on provincial differences that affect their members and consumers. Ontario has the largest population of home inspectors which was estimated in 2013 as part of a government survey at being around 1500.[4]

To date, Ontario Association of Certified Home Inspectors is the only association which has mandated that its members migrate to the CAN/CSA A770-16 Home Inspection Standard, with a date of migration set as February 28, 2020. Other national and provincial associations have set it as an option to be added to other supported standards.

In Canada, only Alberta and British Columbia have implemented government regulation for the home inspection profession. The province of Ontario has proceeded through the process, with the passage of regulatory procedure culminating in the Home Inspection Act, 2017 to license Home Inspectors in that province. It has received royal assent but is still awaiting the development of regulations and proclamation to become law.

In Ontario, there are two provincial Associations, OAHI (the Ontario Association of Home Inspectors) and OntarioACHI (the Ontario Association of Certified Home Inspectors). Both claim to be the largest association in the province. OAHI, formed by a private member's Bill in the Provincial Assembly, has the right in law to award the R.H.I. (Registered Home Inspector) designation to anyone on its membership register. The R.H.I. designation, however, is a reserved designation, overseen by OAHI under the Ontario Association of Home Inspectors Act, 1994. This Act allows OAHI to award members who have passed and maintained strict criteria set out in their membership bylaws and who operate within Ontario. Similarly, OntarioACHI requires equally high standards for the award of their certification, the Canadian-Certified Home Inspector (CCHI) designation. To confuse things, Canadian Association of Home and Property Inspectors (CAHPI) own the copyright to the terms Registered Home Inspector and RHI. Outside of Ontario, OAHI Members cannot use the terms without being qualified by CAHPI.

The proclamation of the Home Inspection Act, 2017, requires the dissolution of the Ontario Association of Home Inspectors Act, 1994, which will remove the right to title in Ontario of the RHI at the same time removing consumer confusion about the criteria for its award across Canada.

United Kingdom

[edit]

A home inspector in the United Kingdom (or more precisely in England and Wales), was an inspector certified to carry out the Home Condition Reports that it was originally anticipated would be included in the Home Information Pack.

Home inspectors were required to complete the ABBE Diploma in Home Inspection to show they met the standards set out for NVQ/VRQ competency-based assessment (Level 4). The government had suggested that between 7,500 and 8,000 qualified and licensed home inspectors would be needed to meet the annual demand of nearly 2,000,000 Home Information Packs. In the event, many more than this entered training, resulting in a massive oversupply of potential inspectors.

With the cancellation of Home Information Packs by the coalition Government in 2010, the role of the home inspector in the United Kingdom became permanently redundant.

Inspections of the home, as part of a real estate transaction, are still generally carried out in the UK in the same manner as they had been for years before the Home Condition Report process. Home Inspections are more detailed than those currently offered in North America. They are generally performed by a chartered member of the Royal Institution of Chartered Surveyors.

India

[edit]

The concept of home inspection in India is in its infancy. There has been a proliferation of companies that have started offering the service, predominantly in Tier-1 cities such as Bangalore, Chennai, Kolkata, Pune, Mumbai, etc. To help bring about a broader understanding among the general public and market the concept, a few home inspection companies have come together and formed the Home Inspection Association of India.[5]

After RERA came into effect, the efficacy and potency of home inspection companies has increased tremendously. The majority of homeowners and potential home buyers do not know what home inspection is or that such a service exists.

The way that home inspection is different in India[6] than in North America or United Kingdom is the lack of a government authorised licensing authority. Apart from the fact that houses in India are predominantly built with kiln baked bricks, concrete blocks or even just concrete walls (predominantly in high rise apartments) this means the tests conducted are vastly different. Most home inspection companies conduct non-destructive testing of the property, in some cases based on customer requirement, tests that require core-cutting are also performed.

The majority of homeowners are not aware of the concept of home inspection in India. The other issue is that the balance of power is highly tilted toward the builder; this means the home buyers are stepping on their proverbial toes, because in most cases, the home is the single most expensive purchase in their lifetime, and the homeowners do not want to come across as antagonising the builders.

Home inspection standards and exclusions

[edit]

Some home inspectors and home inspection regulatory bodies maintain various standards related to the trade. Some inspection companies offer 90-day limited warranties to protect clients from unexpected mechanical and structural failures; otherwise, inspectors are not responsible for future failures.[a] A general inspection standard for buildings other than residential homes can be found at the National Academy of Building Inspection Engineers.

Many inspectors may also offer ancillary services such as inspecting pools, sprinkler systems, checking radon levels, and inspecting for wood-destroying organisms. The CAN/CSA-A770-16 standard allows this (in-fact it demands swimming pool safety inspections as a requirement) and also mandates that the inspector be properly qualified to offer these. Other standards are silent on this.

Types of inspections

[edit]

Home buyers and home sellers inspections

[edit]

Home inspections are often used by prospective purchasers of the house in question, in order to evaluate the condition of the house prior to the purchase. Similarly, a home seller can elect to have an inspection on their property and report the results of that inspection to the prospective buyer.

Foreclosure inspection

[edit]

Recently foreclosed properties may require home inspections.

Four point inspection

[edit]

An inspection of the house's roof, HVAC, and electrical and plumbing systems is often known as a "four-point inspection", which insurance companies may require as a condition for homeowner's insurance.

Disaster inspection

[edit]

Home inspections may occur after a disaster has struck the house. A disaster examination, unlike a standard house inspection, concentrates on damage rather than the quality of everything visible and accessible from the roof to the basement.

Inspectors go to people's homes or work places who have asked for FEMA disaster aid.

Section 8 inspection

[edit]

In the United States, the federal and state governments provide housing subsidies to low-income people through the Section 8 program. The government expects that the housing will be "fit for habitation" so a Section 8 inspection identifies compliance with HUD's Housing Quality Standards (HQS).

Pre-delivery inspection

[edit]
See also: Pre-delivery inspection

An inspection may occur in a purchased house prior to the deal's closure, in what is known as a "pre-delivery" inspection.

Structural inspection

[edit]

The house's structure may also be inspected. When performing a structural inspection, the inspector will look for a variety of distress indications that may result in repair or further evaluation recommendations.

In the state of New York, only a licensed professional engineer or a registered architect can render professional opinions as to the sufficiency structural elements of a home or building.[11] Municipal building officials can also make this determination, but they are not performing home inspections at the time they are rendering this opinion. Municipal officials are also not required to look out for the best interest of the buyer. Some other states may have similar provisions in their licensing laws. Someone who is not a licensed professional engineer or a registered architect can describe the condition of structural elements (cracked framing, sagged beams/roof, severe rot or insect damage, etc.), but are not permitted to render a professional opinion as to how the condition has affected the structural soundness of the building.

Various systems of the house, including plumbing and HVAC, may also be inspected.[12]

Thermal imaging Inspection

[edit]

A thermal imaging inspection using an infrared camera can provide inspectors with information on home energy loss, heat gain/loss through the exterior walls and roof, moisture leaks, and improper electrical system conditions that are typically not visible to the naked eye. Thermal imaging is not considered part of a General Home Inspection because it exceeds the scope of inspection Standards of Practice.

Pool and spa inspection

[edit]

Inspection of swimming pools and spas is not considered part of a General Home Inspection because their inspection exceeds the scope of inspection Standards of Practice. However, some home inspectors are also certified to inspect pools and spas and offer this as an ancillary service.[13]

Tree health inspection

[edit]

Inspection of trees on the property is not considered part of a General Home Inspection because their inspection exceeds the scope of inspection Standards of Practice. This type of inspection is typically performed by a Certified Arborist and assesses the safety and condition of the trees on a property before the sales agreement is executed.[14]

Property inspection report for immigration

[edit]

The UKVI (United Kingdom Visa and Immigration) issued guidance on the necessity of ensuring that properties must meet guidelines so that visa applicants can be housed in properties which meet environmental and health standards. Part X of the Housing Act 1985 provides the legislative grounding for the reports - primarily to ensure that a property is not currently overcrowded, that the inclusion of further individuals as a result of successful visa applications - whether spouse visa, dependent visa, indefinite leave to remain or visitor visa, can house the applicants without the property becoming overcrowded. Reports are typically prepared by environmental assessors or qualified solicitors in accordance with HHSRS (Housing Health and Safety Rating Scheme). Property inspection reports are typically standard and breakdown the legal requirements.

Pre-Listing Home Inspection

[edit]

A pre-listing inspection focuses on all major systems and components of the house including HVAC, electrical, plumbing, siding, doors, windows, roof and structure. It's a full home inspection for the seller to better understand the condition of their home prior to the buyer's own inspection.

Radon mitigation is any process used to reduce radon gas concentrations in the breathing zones of occupied buildings, or radon from water supplies. Radon is a significant contributor to environmental radioactivity and indoor air pollution. Exposure to radon can cause serious health problems such as lung cancer.[1]

Mitigation of radon in the air by active soil depressurization is most effective. Concrete slabs, sub-floors, and/or crawlspaces are sealed, an air pathway is then created to exhaust radon above the roof-line, and a radon mitigation fan is installed to run permanently. In particularly troublesome dwellings, air exchangers can be used to reduce indoor radon concentrations. Treatment systems using aeration or activated charcoal are available to remove radon from domestic water supplies. There is no proven link between radon in water and gastrointestinal cancers; however, extremely high radon concentrations in water can be aerosolized by faucets and shower heads and contribute to high indoor radon levels in the air.

Testing

[edit]

The first step in mitigation is testing. No level of radiation is considered completely safe, but as it cannot be eliminated, governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced. The World Health Organization's International Radon Project has recommended an action level of 100 Bq/m3 (2.7 pCi/L) for radon in the air.[2] Radon in the air is considered to be a larger health threat than radon in domestic water. The US Environmental Protection Agency recommendation is to not test for radon in water unless a radon in air test shows concentrations above the action level. However, in some U.S. states such as Maine where radon levels are higher than the national average, it is recommend that all well water should be tested for radon. The U.S. government has not set an action level for radon in water.

Air-radon levels fluctuate naturally on a daily and seasonal basis. A short term test (90 days or less) might not be an accurate assessment of a home's average radon level, but is recommended for initial testing to quickly determine unhealthy conditions. Transient weather such as wind and changes in barometric pressure can affect short-term concentrations as well as ventilation, such as open windows and the operation of exhaust fans.

Testing for radon in the air is accomplished using passive or active devices placed in the building. Some devices are promptly sent to a laboratory for analysis, others calculate the results on-site including digital Radon detectors. Radon-in-water testing requires a water sample being sent to a laboratory.

Retesting is recommended in several situations, for example, before spending money on the installation of a mitigation system. Test results which exceed accuracy tolerances also require re-testing. When a mitigation system installation is warranted, a retest after the system is functional is advised to be sure the system is effectively reducing the radon concentration below the action level, and after any mitigation system repairs such as replacing a fan unit. The US EPA recommends retesting homes with radon problems every two years to ensure proper system function. Due to the vast fluctuation in indoor radon levels, the EPA recommends all homes be tested at least once every five years.[3]

Testing in the United States

[edit]
Radon map of the United States

ASTM E-2121 is a US standard for reducing airborne radon in homes as far as practicable below the action level of 4 picocuries per liter (pCi/L) (148 Bq/m3).[4][5] Some states recommend achieving 2.0 pCi/L or less.

Radon test kits are commercially available[6] and can be used by homeowners and tenants and in limited cases by landlords, except when a property is for sale.

Commercially available test kits include a passive collector that the user places in the lowest livable floor of the house for 2 to 7 days. The user then sends the collector to a laboratory for analysis. Long-term kits, taking collections from 91 days to one year, are also available. Open land test kits can test radon emissions from the land before construction begins, but are not recommended by the EPA because they do not accurately predict the final indoor radon level. The EPA and the National Environmental Health Association have identified 15 types of radon test devices.[7] A Lucas cell is one type of device.

Retesting is specifically recommended in several situations. Measurements between 4 and 10 pCi/L (148 and 370 Bq/m3) warrant a follow-up short-term or long-term radon test before mitigation. Measurements over 10 pCi/L (370 Bq/m3) warrant only another short-term test (not a long-term test) so that abatement measures are not unduly delayed.

Progress has been made regarding radon in the home. A total of 37 states have now[when?] passed legislation requiring home-sellers to disclose known radon levels before completing the transaction (although only a handful have introduced criminal penalties for misrepresentation).[8] And over half the legislatures have written radon into their state's building code.[9] Purchasers of real estate may delay or decline a purchase if the seller has not successfully abated radon to less than 4 pCi/L.

The accuracy of the residential radon test depends upon whether closed house conditions are maintained. Thus the occupants will be instructed not to open windows, etc., for ventilation during the pendency of test, usually two days or more. However, the occupants, if the present owners, will be motivated to pass the test and insure the sale, so they might be tempted to open a window to get a lower radon score. Moreover, there may be children or immature teens or young adults in the house who will open a window for ventilation notwithstanding instructions not to do so, particularly in uncomfortably hot weather. Accordingly, whether the potential purchaser should trust the result of such a test is problematic.

Management of radon service provider certification has evolved since being introduced by the EPA in 1986. In the 1990s this service was "privatized" and the National Environmental Health Association (NEHA) helped transition the voluntary National Radon Proficiency Program (NRPP) to be administered by private firms. As of 2012, the NRPP is administered by the American Association of Radon Scientists and Technologists (AARST).[10]

Some states, such as Maine, require landlords to test their rental properties and turn the results in to the state. In limited cases the landlord or tenants may do the testing themselves. The rules in each state vary. In many cases there are private contractors that will inspect hired by the city.

Testing in Canada

[edit]

Health Canada recommends regular annual testing, either by hiring a qualified tester or by using a home-testing kit that should be checked quarterly.[11]

Canadian Government, in conjunction with the territories and provinces, developed the guideline[12] to indicate when remedial action should be taken was originally set at 800 Bq/m3 (becquerels per cubic meter) and since reduced to 200 Bq/m3. This new guideline was approved by the Federal Provincial Territorial Radiation Protection Committee in October 2006.[13]

Testing in the UK

[edit]

Radon testing in the UK is managed by UKradon and the UKHSA.[14]

Testing in Norway

[edit]

The Norwegian Radiation and Nuclear Safety Authority (DSA) developed the protocol[15] for radon measurements in residential dwellings[16] with respect to rental accommodation, which is governed by The Radiation Protection Regulations.[17]

Methods of radon gas mitigation

[edit]
Part of a radon mitigation system including the fan and vent pipe is visible near the gutter downspout.

Because high levels of radon have been found in every state of the United States,[18] testing for radon and installing radon mitigation systems has become a specialized industry since the 1980s. Many states have implemented programs that affect home buying and awareness in the real estate community; however, radon testing and mitigation systems are not generally mandatory unless specified by the local jurisdiction.[19]

Anticipated high radon levels can be mitigated during building design and construction by a combination of ensuring a perfectly sealed foundation, allowing sufficient passive dispersal of under-slab gas around rather than through the building, and proper building ventilation. In many instances, such approaches may achieve a sufficient reduction of radon levels compared to other buildings where such approaches were not taken. However, quality of implementation is crucial and testing after construction is necessary. For instance, even a small gap in the sealing of the slab may be sufficient for excessive quantities of radon to enter, given pressure differentials.

Where such approaches were not taken during construction or have proven insufficiently effective, remediation is needed. According to the EPA's "A Citizen's Guide to Radon",[20] the method to reduce radon "primarily used is a vent pipe system and fan, which pulls radon from beneath the house and vents it to the outside", which is also called sub-slab depressurization, soil suction, or active soil depressurization (ASD). Generally indoor radon can be mitigated by sub-slab depressurization and exhausting such radon-laden air to the outdoors, away from windows and other building openings.[21] "EPA generally recommends methods which prevent the entry of radon. Soil suction, for example, prevents radon from entering your home by drawing the radon from below the home and venting it through a pipe, or pipes, to the air above the home where it is quickly diluted" and "EPA does not recommend the use of sealing alone to reduce radon because, by itself, sealing has not been shown to lower radon levels significantly or consistently" according to the EPA's "Consumer's Guide to Radon Reduction: How to Fix Your Home".[22] Ventilation systems can utilize a heat exchanger or energy recovery ventilator to recover part of the energy otherwise lost in the process of exchanging air with the outside. For crawlspaces, the EPA states,[22] "An effective method to reduce radon levels in crawlspace homes involves covering the earth floor with a high-density plastic sheet. A vent pipe and fan are used to draw the radon from under the sheet and vent it to the outdoors. This form of soil suction is called submembrane suction, and when properly applied is the most effective way to reduce radon levels in crawlspace homes."

High radon levels in a Minnesota (USA) basement with a passive under slab vent pipe system can be seen in the left half of the graph. After installation of a radon fan (ASD), a permanent reduction in radon levels to approximately 0.6 pCi/L can be seen in the right half of the graph.
  • The most common approach is active soil depressurization (ASD). Experience has shown that ASD is applicable to most buildings since radon usually enters from the soil and rock underneath and mechanical ventilation is used when the indoor radon is emitted from the building materials. A less common approach works efficiently by reducing air pressures within cavities of exterior and demising walls where radon emitting from building materials, most often concrete blocks, collects.
  • Above slab air pressure differential barrier technology (ASAPDB) requires that the interior pressure envelope, most often drywall, as well as all ductwork for air conditioning systems, be made as airtight as possible. A small blower, often no more than 15 cubic feet per minute (0.7 L/s) may then extract the radon-laden air from these cavities and exhaust it to the out of doors. With well-sealed HVAC ducts, very small negative pressures, perhaps as little as 0.5 pascal (0.00007 psi), will prevent the entry of highly radon-laden wall cavity air from entering into the breathing zone. Such ASAPDB technology is often the best radon mitigation choice for high-rise condominiums as it does not increase indoor humidity loads in hot humid climates, and it can also work well to prevent mold growth in exterior walls in heating climates.
  • In hot, humid climates, heat recovery ventilators (HRV) as well as energy recovery ventilators (ERV) have a record of increasing indoor relative humidity and dehumidification demands on air conditioning systems. Mold problems can occur in homes that have been radon mitigated with HRV and ERV installations in hot, humid climates.[citation needed] HRVs and ERVs have an excellent record in cold dry climates.
  • A recent technology is based on building science. It includes a variable rate mechanical ventilation system that prevents indoor relative humidity from rising above a preset level such as 50% which is currently suggested by the US Environmental Protection Agency and others as an upper limit for the prevention of mold. It has proven to be especially effective in hot, humid climates. It controls the air delivery rate so that the air conditioner is never overloaded with more moisture than it can effectively remove from the indoor air.
    • It is generally assumed that air conditioner operation will remove excess moisture from the air in the breathing zone, but it is important to note that just because the air conditioner cools does not mean that it is also dehumidfying. If Δt is 14 degrees or less, it may not dehumidify at all even though it is cooling.
    • Factors that are likely to aggravate indoor humidity problems from mechanical ventilation–based radon installations are as follows and an expert radon mitigator/building scientist will check for and correct any and all of the following when he or she performs radon mitigation procedures:
      • Air conditioner duct leaks located outside the breathing zone, such as in the attic.
      • Excessive exhaust fan operation
      • Oversize or over-capacity air conditioners
      • AC air handler fans that do not stop running when the air conditioner compressor stops running.
      • Delta t (Δt), which is the amount that the air is cooled as it is passed through the air conditioner's cooling coils. A good Δt performance figure for home air conditioners is about 20 °F (11 °C). In comparison, automobile air conditioners deliver Δt performance of 32 to 38 °F (18 to 21 °C). A Δt of 14 °F (8 °C) will dehumidify poorly if at all.

In South Florida, most radon mitigation is performed by use of fixed rate mechanical ventilation. Radon mitigation training in Florida does not include problems associated with mechanical ventilation systems, such as high indoor humidity, mold, moldy odors, property damage or health consequences of human occupation in high humidity of moldy environments[citation needed]. As a result, most Florida radon mitigators are unaware of and do not incorporate existing building science moisture management technology into mechanical ventilation radon installations. Home inspectors may not necessarily be aware of the mold risks associated with radon mitigation by mechanical ventilation.

The average cost for an ASD radon mitigation system in Minnesota is $1500.[23] These costs are very dependent on the type of home and age of construction.[24]

Methods of radon-in-water mitigation

[edit]

Radon removal from water supplies may be at a treatment plant, point of entry, or point of use. Public water supplies in the United States were required to treat for radionuclides beginning in 2003 but private wells are not regulated by the federal government as of 2014. The radon can be captured by granular activated charcoal (GAR) or released into the air through aeration of the water. Radon will naturally dissipate from water over a period of days, but the quantity of storage needed to treat the water in this manner makes home systems of this type impracticably large.[25]

Activated carbon systems capture radon from the water. The amount of radiation accumulates over time and the filter material may reach the level of requiring disposal as a radioactive waste. However, in the United States there are no regulations concerning radiation levels and disposal of radon treatment waste as of 2014.

Aeration systems move the radon from the water to the air. Radon gas discharged into the air is the release of a pollutant, and may become regulated in the United States.

Hoffman Estates is a village in Cook County, Illinois, United States. It is a suburb of Chicago. Per the 2020 census, the population was 52,530.[3]

The village previously served as the headquarters for Sears and is one of the American headquarters for Mori Seiki. Now Arena, home of the Windy City Bulls of the NBA G League is part of the village. Between 2006 and 2009, the village hosted the Heartland International Tattoo, one of the largest music and dance festivals of its kind in the Midwest.

History

[edit]
Sunderlage Farm Smokehouse[4](National Register of Historic Places) in Hoffman Estates

Prior to the 1940s, German settlers moved into the area west of Roselle Road and north of Golf Road, then known as Wildcat Grove. The area was sparsely populated until farmers purchased land in the area in the 1940s.

In 1954, Sam and Jack Hoffman, owners of a father-son owned construction company, bought 160 acres of land in the area.[5] The pair constructed homes and began the development of the region which now bears their name. As residents moved in, they voted to incorporate the area, and the Village of Hoffman Estates was incorporated on September 23, 1959.[6][5][7] In 1973, six former town officials, including mayors Edward F. Pinger (1959−1965) and Roy L. Jenkins (1965−1969) were indicted on bribery and tax charges.[8]

Once the Northwest Tollway opened, Schaumburg Township became more attractive to Chicago commuters. In the early 1960s, land annexations north of the tollway and in other neighboring regions more than doubled Hoffman Estates' land area.[9]

The opening of the Woodfield Mall in Schaumburg to the east in 1971 made the area a major business center. An attempt to change the name of the village to East Barrington, among other names, was made in the early 1980s but failed upon a residential vote.[10]

In the 1990s, the Prairie Stone Business Park began development. This 750-acre (3.0 km2) planned multi-purpose business park[11] is bounded by Illinois Route 59 on the east, Interstate 90 on the south, Illinois Route 72 on the north, and Beverly Road on the west. The business park came to fruition in 1993 when Sears, Roebuck and Company relocated from the Sears Tower in Chicago to a sprawling headquarters in the northwest part of Prairie Stone.[12][11] That was followed in by Indramat and Quest International, which in 1995 also opened facilities in the park.[13][14][15] Throughout the 1990s, a health and wellness center and child care facility were developed, as well as other smaller office buildings, and a branch of Northern Illinois University. Development of the business park is still ongoing, and recent additions in the 2000s include the 11,000-seat Now Arena; office buildings for Serta, WT Engineering, I-CAR, and Mary Kay; a Cabela's outdoor outfitters store; a 295-room Marriott hotel; and the 400,000-square-foot (37,000 m2) Poplar Creek Crossing Retail Center, which is anchored by Target and numerous other big-box retailers. Future development will include further office buildings and retail development, Sun Island Hotel and Water Park, an amphitheater, and restaurants.

In 2011, the Village of Hoffman Estates took over ownership of the Now Arena.[16] On June 23, 2020, the Village of Hoffman Estates approved an $11.5 million deal to rename the Sears Centre Arena to the "NOW Arena".[17]

In the fall of 2016, papers and artifacts from President Barack Obama's administration began to arrive in town, where they are being stored in a building on Golf Road. The site is their temporary home while construction takes place on the Barack Obama Presidential Center in Jackson Park, Chicago, and is not open to the public.[18]

In January 2020, the Centers for Disease Control and Prevention (CDC) confirmed the second U.S. case of COVID-19 in a Hoffman Estates resident. The patient, a woman in her 60s returning from Wuhan, China, was treated at St. Alexius Medical Center.[19] Her husband was later infected in the first case of human-to-human transmission of the SARS-CoV-2 virus in the United States.[20]

Very happy with my experience. They were prompt and followed through, and very helpful in fixing the crack in my foundation.

USS was excellent. They are honest, straightforward, trustworthy, and conscientious. They thoughtfully removed the flowers and flower bulbs to dig where they needed in the yard, replanted said flowers and spread the extra dirt to fill in an area of the yard. We've had other services from different companies and our yard was really a mess after. They kept the job site meticulously clean. The crew was on time and friendly. I'd recommend them any day! Thanks to Jessie and crew.

It was a pleasure to work with Rick and his crew. From the beginning, Rick listened to my concerns and what I wished to accomplish. Out of the 6 contractors that quoted the project, Rick seemed the MOST willing to accommodate my wishes. His pricing was definitely more than fair as well. I had 10 push piers installed to stabilize and lift an addition of my house. The project commenced at the date that Rick had disclosed initially and it was completed within the same time period expected (based on Rick's original assessment). The crew was well informed, courteous, and hard working. They were not loud (even while equipment was being utilized) and were well spoken. My neighbors were very impressed on how polite they were when they entered / exited my property (saying hello or good morning each day when they crossed paths). You can tell they care about the customer concerns. They ensured that the property would be put back as clean as possible by placing MANY sheets of plywood down prior to excavating. They compacted the dirt back in the holes extremely well to avoid large stock piles of soils. All the while, the main office was calling me to discuss updates and expectations of completion. They provided waivers of lien, certificates of insurance, properly acquired permits, and JULIE locates. From a construction background, I can tell you that I did not see any flaws in the way they operated and this an extremely professional company. The pictures attached show the push piers added to the foundation (pictures 1, 2 & 3), the amount of excavation (picture 4), and the restoration after dirt was placed back in the pits and compacted (pictures 5, 6 & 7). Please notice that they also sealed two large cracks and steel plated these cracks from expanding further (which you can see under my sliding glass door). I, as well as my wife, are extremely happy that we chose United Structural Systems for our contractor. I would happily tell any of my friends and family to use this contractor should the opportunity arise!

USS did an amazing job on my underpinning on my house, they were also very courteous to the proximity of my property line next to my neighbor. They kept things in order with all the dirt/mud they had to excavate. They were done exactly in the timeframe they indicated, and the contract was very details oriented with drawings of what would be done. Only thing that would have been nice, is they left my concrete a little muddy with boot prints but again, all-in-all a great job

What a fantastic experience! Owner Rick Thomas is a trustworthy professional. Nick and the crew are hard working, knowledgeable and experienced. I interviewed every company in the area, big and small. A homeowner never wants to hear that they have foundation issues. Out of every company, I trusted USS the most, and it paid off in the end. Highly recommend.
