In most BC homes built prior to 1990, the presence of some building materials with asbestos is almost always present. It was commonly used in office buildings, public buildings and schools. It insulated hot water heating systems and was put into walls and ceilings as insulation against fire and sound. It has also been found in many products around the house: clapboard; shingles and felt for roofing; exterior siding; pipe covering; compounds and cement; textured and latex paints; acoustical ceiling tiles and plaster; vinyl floor tiles; and appliance wiring to name a few.
Canada Mortgage & Housing Corporation (CMHC) cautions: “To avoid health risks through prolonged exposure to asbestos fibres, proper precautions must be taken when repairs or renovations disturb asbestos-containing materials, such as: disturbing loose-fill vermiculite insulation which may contain asbestos; removing deteriorating roofing shingles and siding containing asbestos; ripping away old asbestos insulation from around a hot water tank; sanding or scraping vinyl asbestos floor tiles; breaking apart acoustical ceiling tiles containing asbestos; sanding or scraping older water-based asbestos coatings such as roofing compounds, spackling, sealants, paint, putty, caulking or drywall….”.

Recognizing and disclosing the possibility of asbestos is not within the scope of your home inspection. If your inspector suspects the presence of asbestos, he/she may suggest further evaluation and analysis by a qualified professional.
