From the 1930s to the 1990s, asbestos was used in many building materials such as vinyl and linoleum flooring, stucco, insulation, roof felt shingles, gypsum board filling compound, incandescent light fixture backings, and deck under-sheeting. When disturbed, it can be released into the air, rendering it harmful to anyone working or living on the property. In order to properly identify asbestos, a qualified testing company or asbestos surveyor must be retained to ensure the safety of your installation crews and of the homeowners.
