Asbestos, once widely used in construction for its heat resistance and durability, is a hazardous material linked to serious health risks.
Although its use has declined significantly, many homes built before the 1980s may still have asbestos-containing materials.
Insulation
In 2023, asbestos manufacturers produced 1.3 million metric tons of asbestos products, down from two million metric tons in 2010. Although it is not commonly used in homes, one common area where you may find asbestos is in your home’s insulation materials. This includes insulation around boilers, ducts and pipes.
Flooring
Vinyl floor tiles, as well as the adhesive used to install them, often contained asbestos. When these tiles become disturbed or damaged, such as during renovations or repairs, asbestos fibers can become airborne, posing a health risk to anyone nearby.
Popcorn ceilings
Popcorn ceilings, also known as textured ceilings, were popular in the mid-20th century and often contained asbestos due to its fireproofing and soundproofing qualities. If your home has this type of ceiling and it is in poor condition or you are planning to remove it, take precautions to avoid asbestos exposure.
Roofing
Some roofing materials may contain asbestos. This includes roofing shingles, felt and cement sheets. As these materials age or undergo damage, asbestos fibers can become released into the air, potentially causing health problems if inhaled.
Pipes and siding
Asbestos was commonly used in pipes and siding materials to provide insulation and fire resistance. If your home has older plumbing or siding, determine whether the builder used asbestos-containing materials.
Other areas
Other potential sources of asbestos in the home include textured paint, caulking and even some appliances.
While asbestos is less commonly used today, be vigilant, especially in older homes. Take appropriate precautions during any maintenance or renovation work.
