Asbestos in Older Homes and Renovation Projects
Why asbestos in older materials becomes a greater concern when it is damaged or disturbed during repair, renovation, or demolition.
Homes and buildings constructed before 1980 may contain asbestos in insulation, floor tiles, pipe coverings, and other materials. Intact asbestos is not an immediate hazard, but cutting, drilling, sanding, or demolishing these materials releases microscopic fibers into the air, creating a significant inhalation risk.
Why renovation changes the risk picture
Cutting, drilling, sanding, scraping, demolition, and removal can disturb asbestos-containing materials and make airborne exposure more likely. OSHA specifically regulates asbestos in construction and renovation settings because these activities can create significant exposure without proper controls. OSHA
Older buildings still matter
CDC notes that people can still be exposed to asbestos in older buildings and in some consumer products, even though use declined after peaking in the 1970s. CDC
