Homes built prior to the 1970’s could contain asbestos in insulation, plumbing, paint, wall joint compound, and other building materials. However, as long as the materials are in good condition, they pose no danger. Asbestos is only a threat if the fibers are released into the air and can be inhaled.
Renovations or demolitions of materials containing asbestos can release the fibers into the air. Therefore, the National Emissions Standards for Hazardous Air Pollutants (NESHAP) requires the owner of any property containing asbestos building materials to get an asbestos inspection prior to any demolitions or renovations of that property.
