Unless materials in your home are labeled as having asbestos, the only way to be certain is to have your home tested. If you are unsure if materials in your home have asbestos, you should treat them as if they do. Until these materials can be tested, do not disturb them to keep potential asbestos fibers from becoming airborne. If you are planning a renovation in your home and you are unsure if the building materials have asbestos, you should have your home tested before performing the renovation.
