Find my pathAbout this term
Asbestos was widely used in homes built before 1980 and remained legal until the 1990s. Common sources include pipe insulation, floor tiles, ceiling tiles, roofing materials, and siding. Undisturbed asbestos is not immediately dangerous, but fiber release during disturbance or deterioration poses serious health risks. Abatement requires trained professionals and proper containment. Inspectors identify likely asbestos materials and recommend testing before renovation work.
Pro Tip
If your home was built before 1980, assume asbestos may be present. Have certified contractors handle abatement.
Example
A home inspection of a 1975 home identified suspected asbestos in pipe insulation and floor tiles. Lab testing confirmed asbestos presence. Rather than immediate removal, the homeowner planned abatement before any renovation disturbing these materials.
