You may already be aware that the use of asbestos in construction materials has waned dramatically. A naturally occurring mineral, asbestos exposure is linked to mesothelioma, a rare cancer affecting the lining of the abdominal cavity or chest, and a scarring of the lungs (asbestosis). The Environmental Protection Agency (EPA) banned the use of asbestos-containing materials in the late nineties; there are two instances where you may have to worry about asbestos exposure: when you move into a home built before 1989, or when insulation containing asbestos needs to be removed or disturbed during a renovation.

Where in your home is asbestos most likely to be found?

• Drywall installed prior to 1990 may contain asbestos, which was used to fill gaps between boards and seal seams. If old drywall is being removed as part of the renovation project, it must first be subjected to asbestos testing.
• Floor tiles manufactured before 1990 may contain asbestos fibers. Back then, asbestos fibers were added to vinyl to enhance strength and insulation. In asphalt tiles, asbestos fibers are integrated very tightly, so it is usually never a problem. Regardless of the type of flooring material, it is best to discuss the potential risks and solutions with your renovation company.
• As mentioned earlier, asbestos can be found in insulation around hot water pipes and tanks. It is more commonly discovered in the wall and attic insulation at the time of renovation.

Should your renovation project require removing all the old materials, asbestos testing is highly recommended. On the other hand, if you don’t expect to disturb or tear down asbestos-containing materials in insulation, tiles, ceiling or roofing materials, testing may not be necessary.
