Asbestos in Canadian Homes
A comprehensive guide to understanding asbestos risks, identification methods, and remediation costs for Canadian homeowners.
Health and Safety Warning
Asbestos is a serious health hazard when disturbed. Never attempt to remove or disturb materials you suspect contain asbestos. Always consult with certified professionals for testing and remediation.
What is Asbestos?
Asbestos is a naturally occurring mineral that was widely used in building materials until the late 1980s due to its heat resistance, strength, and insulating properties. It was commonly used in insulation, floor tiles, ceiling materials, pipe coverings, and many other construction materials.
When asbestos-containing materials are damaged or disturbed, they release microscopic fibers that can be inhaled and lead to serious health problems, including asbestosis, lung cancer, and mesothelioma.
