Asbestos is a carcinogen that was used extensively in building materials prior to the 1970s. It can be commonly found in a duct and pipe insulation, vermiculite attic insulation, ceiling and wall acoustical tiles, cement asbestos siding, and floor tiles (and adhesives).
Please do not let that frighten you, though. If the asbestos-containing materials in your home are undamaged, contact Encompass Environmental® immediately. It’s more dangerous to disturb them, says the Environmental Protection Agency (EPA) so it is best to contact professionals to take care of this for you.
