Unfortunately, it's hard to know if you have asbestos in your home because it's often mixed with other materials. However, if you are renovating or demolishing a home built before 1990, it's likely that at least some parts of the home will contain asbestos. Asbestos is only harmful when materials containing asbestos are disturbed, so know where to look for it and how to remove it safely.
