The most common sign of asbestos is the age of your home. Asbestos was banned in drywall in 1977, though many products still contained asbestos until the 1980s. Indicators of possible asbestos in your home include:

  • Your home's age, if built before 1980

  • You have a home with vinyl flooring or millboard that was installed between 1952 and 1982

  • Your home has corrugated roofing

  • Your home has walls made from cement sheets

  • Your home has vermiculite insulation

Asbestos was commonly used in construction before the 1980s. While homes built after that time are unlikely to contain asbestos, there is still a possibility. Asbestos was found in materials such as flooring, drywall/joint compound, ceiling textures (like popcorn ceilings), roofing, siding, felts, HVAC systems, and more. If you're concerned about asbestos in your home, it's important to consult with an experienced asbestos professional to assess the likelihood of its presence.

Since the EPA partially banned asbestos in 1989, it is no longer used to manufacture new siding in the United States; production had largely ceased by the early 1980s. Many other countries, such as Canada, Iceland, and Denmark, also have bans on asbestos. However, asbestos siding is still present in many homes built before the late 1980s. The only definitive way to know if your siding contains asbestos is to have it professionally lab-tested.

Costs depend on property size, test types, and additional services like mold sampling.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

Asbestos siding can be dangerous, but it doesn't necessarily pose a health risk if it's in good condition and left undisturbed. The danger comes from inhaling asbestos fibers, which can be released if the siding is damaged, deteriorating, crumbling, or disturbed during remodeling or repairs. Exposure to these airborne fibers can cause serious, life-threatening diseases like asbestosis (lung scarring), mesothelioma (an aggressive cancer), and other lung cancers.

If your asbestos siding is intact, the general recommendation is to leave it alone. However, if it's damaged or you plan to renovate, it's crucial to handle it safely. Due to the significant health risks and the difficulty of containing the fibers, it is not recommended to perform any asbestos work yourself. Instead, you should hire a professional asbestos removal company to inspect, repair, encapsulate, or remove the material. The presence of asbestos can also negatively impact your property's value.
