Will a Home Inspector Check for Asbestos?
Eliminate asbestos guesswork with an inspection
Only qualified pros can check for asbestos.
Asbestos was frequently used to build homes pre-1980.
Asbestos exposure increases the risk of cancer.
An asbestos inspection costs between $280–$780.
Home inspectors have a checklist they examine to determine any potential issues or hazards with a house. But do home inspections check for asbestos? Surprisingly, they don’t. An inspector might identify areas suspected to have asbestos in your home—particularly if it’s an older house—but it’s not usually part of their inspection. Find out why general home inspections don’t check for asbestos and what you need to know if you have it in your home.
Do Home Inspections Check for Asbestos?
Unfortunately, standard home inspections don’t check for asbestos, and homeowners aren’t obligated to tell buyers about existing asbestos. To avoid liability, most home inspectors won’t closely examine areas that require specific expertise, which includes asbestos, as it can be tricky to detect. Special equipment and testing are needed to confirm the presence of asbestos, and it can only be done by qualified and licensed asbestos inspectors.
What Is Asbestos and Why Is It a Health Hazard?
Asbestos is a naturally occurring mineral fiber that is heat- and chemical-resistant. Because of its fireproof qualities, it was widely used as a fire-retardant during the construction of homes and commercial buildings before the 1980s. Some common places where asbestos was used include:
Pipes
Vinyl sheet flooring
Roofs and shingles
Gas-fired fireplaces
Oil and coal furnaces
Paints
Boiler insulation
Vermiculite attic insulation
Ceiling tiles
Sheetrock
Siding shingles
According to the National Institute of Health (NIH), the International Agency for Research on Cancer (IARC) concluded in 1977 that asbestos qualifies as a carcinogen. It also revealed exposure to asbestos fibers is linked to an increased risk of lung cancer, mesothelioma, and asbestosis—a chronic lung condition caused by prolonged inhalation of asbestos fibers. Following these findings, the Occupational Health and Safety Administration (OSHA) and the Environmental Protection Agency (EPA) began to regulate the use of asbestos.
Since 2019, asbestos has been banned in the production of most building products including pipeline wrap, cement, adhesives and sealants, roofing felt and roof coatings, and millboard. In 2022, the EPA proposed a ban on the ongoing use of chrysotile asbestos that is currently imported into the U.S.
When Is a Home Inspection Check for Asbestos Necessary?
If you’re moving into a house built before 1980 and the idea of having asbestos in the home is a concern, it may be a good idea to schedule an inspection to test for asbestos. The same goes if you’re planning to renovate a home from this period. You stand a higher risk of breathing in asbestos fibers and general exposure if materials containing asbestos are disturbed during demolition and renovations.
The only way to know for sure if there’s asbestos in your home is to hire an asbestos professional. An asbestos inspector will review all structures in your home to assess their condition and take samples of various materials for testing. On average, an asbestos inspection costs $480, with a range from $280 to $780, depending on the size, condition, and location of your home.
Who Can You Hire to Check for Asbestos?
You can hire a certified asbestos inspector or an environmental consultant to check your property for asbestos. These professionals are trained in the detection of asbestos by examining the property and safely collecting and testing samples. Some inspectors may work for companies that also contain and remove asbestos, though this is not always the case.
Many states provide certification for asbestos inspectors, so you can find a list of verified asbestos professionals in your state through the state government or the Environmental Protection Agency.
Radon is a very common, undetectable threat in homes, and it's not checked for in standard home inspections. A typical home inspection also won't check for other hazardous materials such as asbestos, radiation, formaldehyde, methane, and other substances. Many home inspection services will check for these hazards for an additional cost.
What Happens if Asbestos Is Found?
If an asbestos inspector determines the presence of asbestos in your home, what to do next depends on a couple of factors.
Type of Asbestos and Abatement
Asbestos is categorized as either friable or non-friable. Friable asbestos presents more of a risk because it can be easily crumbled or crushed into airborne fibers. Non-friable asbestos is safely maintained in a way that it can’t become airborne and is best left alone—it could become friable if disturbed.
However, in some instances, asbestos professionals can encapsulate an area with asbestos using a protective sealant to prevent it from becoming airborne. Look for a reputable asbestos testing company near you to handle the removal, conduct air tests, and conduct a thorough clean-up.
Disclosure Laws and Who Pays for Asbestos Removal
Most state laws require sellers to disclose any environmental problems, including asbestos, that are known to be in their homes. If a seller is aware of the presence of asbestos in the home and doesn’t disclose it, they could face legal action long after the sale of the home. If asbestos is discovered, the buyer and seller can negotiate whether or not the sale depends on the seller remediating the asbestos.
Frequently Asked Questions
Unlike some home problems, such as water damage or pest infestations, asbestos can be very difficult to spot. Asbestos is a mineral in the form of microscopic fibers and was previously used in building materials for its bonding and fireproofing abilities. Insulation, roof shingles, ceiling tiles, floor tiles, pipe wrappings, soundproofing materials, and textured paint features like popcorn ceilings are common sources of asbestos, particularly in homes built before 1980.
Age is perhaps the biggest indicator of asbestos, as legislation passed in the 1970s labeled asbestos as dangerous and regulated its use in building materials. Signs of age in the form of wear and tear or material degradation are also indicators that asbestos fibers may be leaking into the air, but ultimately, it’s difficult to detect with the naked eye. If you have reason to suspect asbestos in your home, it’s best to hire a certified asbestos inspector.
Whether or not to buy a home containing asbestos is ultimately a decision for the homebuyer, and there are several things to consider. When in good condition and contained, asbestos is unlikely to present a health risk—it’s when those tiny fibers are loose and airborne that they become a problem. Consider any renovations you plan on doing to the home that could disturb existing asbestos and the cost of removal. If an inspection finds asbestos in a home on the market, you could negotiate with the seller for a lower price, though this isn’t a sure thing.
Asbestos is commonly found in certain older homes, depending on the time period in which they were built. Asbestos use in home construction began in the 1920s and peaked after World War II before being limited by legislation in the ’70s, so a house constructed in 1880 is unlikely to contain asbestos, while one built in 1950 is much more likely to. Research a home’s history to determine the time period when it was built and any renovations made since.
