Asbestos Testing

What It Is

Asbestos testing identifies materials in a building that contain asbestos fibres. Also called an asbestos survey or asbestos inspection, this is often the first step required before renovation or demolition permits are issued.

Asbestos was commonly used in insulation, fireproofing, flooring, ceiling texture, drywall joint compound, and more — and because it wasn’t fully banned in Canada until 2018, asbestos-containing materials can be found in buildings of any age.

Why It’s Important

When disturbed (cut, sanded, or demolished), asbestos releases microscopic fibres that can cause severe respiratory diseases including asbestosis, lung cancer, and mesothelioma.
In BC, WorkSafeBC regulations require that asbestos be identified before any renovation or demolition, regardless of building age. Many municipalities, including Vancouver and Coquitlam, also require a completed asbestos survey before issuing a demolition permit.

What’s Involved

j

Site Inspection

A qualified surveyor inspects the work area and identifies all suspect asbestos-containing materials (ACMs).

Sampling

Representative samples are taken from each suspect material type (e.g., drywall joint compound, vinyl flooring, insulation).

Lab Analysis

Samples are tested via Polarized Light Microscopy (PLM) at an accredited lab.

Report

A detailed report identifies locations, material types, asbestos content, and recommendations for safe handling or abatement.

Common Asbestos-Containing Materials

  • Drywall joint compound
  • Textured ceilings (popcorn finish)
  • Vinyl floor tiles & vinyl sheet flooring
  • Vermiculite attic insulation (e.g., Zonolite)
  • Pipe insulation & duct wrap
  • Cement board, siding, or stucco
