In case of doubt, it is recommended to bring in an expert to take a sample. Many building materials may contain asbestos, especially in homes from years before 1982. Examples of materials: gypsum, brick mortar, plaster/cement, joint compound, textured finish (stucco), insulation, duct insulation,resilient flooring, acoustic tiles (suspended ceiling), etc.
Indeed, Quebec regulations stipulate that any material with an asbestos concentration of at least 0.1% is considered as a material containing asbestos and can be dangerous to health. We offer our Asbestos testing services to clients in Montreal, Laval and West Island.
