Planning a reno or demo on a home built before 1990?
You have a responsibility to check for the presence of asbestos in construction materials used around your house. Prior to 1990, WorksafeBC estimates there were approximately 3,000 building materials that somehow incorporated asbestos, often hidden in plain sight.

Conducting a Visual Inspection
Asbestos becomes harmful when the materials containing asbestos are disturbed. However, some property owners have the knowledge and experience to conduct a visual inspection around their property to check for asbestos. To conduct a basic visual inspection for asbestos in your home, download our printable DIY Inspection Diagram (10MB PDF) that includes the potential location(s) and appearance of the threatening materials around your house.
Potential Sources of Asbestos in the Home

• Flooring – vinyl tiles and linoleum sheet flooring as well as flooring adhesive
• Roof felt and shingles
• Roof gutters and down-pipes can be made of asbestos cement
• Asbestos can be found in stucco
• Soffit boards can be made of asbestos cement or asbestos insulating board
• Asbestos cement board siding and under sheeting
• Deck under-sheeting
• Incandescent light fixture backing
• Backing behind recessed lighting
• Acoustic tiles
• Textured ceilings and walls – spray-on popcorn/stipple-coated and sprayed acoustic tiles
• Vermiculite wall insulation
• Artificial fireplace logs and ashes
• Asbestos pad under the fireplace hearth
• Pipe insulation
• Insulation on electrical wires
• Main panel and fuse box – each fuse wire could an individual asbestos flash guard
• Outlets and switches
• Heat reflector for wood stove
• Furnace duct tape
• Furnace door and gasket covers

〈〈〈 CAUTION 〉〉〉
Due to the health threats of asbestos-containing materials, NorHaz recommends conducting only a visual inspection for asbestos with no moving, shifting and if possible, no touching of the materials in question. Contact of any kind with the materials in question should not be undertaken without the proper use of a respirator/mask with a HEPA filter. Standard dust masks are not sufficient to filter all asbestos particles.
At the first sign of asbestos, call NorHaz for a free consultation at toll-free 1-844-466-7429.
Why is Vermiculite Removal or Abatement Necessary?
Vermiculite removal/abatement procedures are especially important for older offices and homes. During the 1900’s, almost three-quarters of the world’s vermiculite used for both homes and buildings came from one mine in Montana, that was later found to have ore that contained dangerously high levels of tremolite asbestos.
Homes and commercial properties developed in the 1990’s and prior, were commonly insulated with vermiculite. It was easy to apply, had effective insulating properties and commonly used throughout Vancouver. Contaminated vermiculite removal services are an essential service that will remove this toxic material. For this reason, our staff is dedicated to ensuring you will live more comfortably and safer with quality vermiculite removal work.
