FAQ

  • Is a hazardous materials survey required before renovating or demolishing a house in BC?

    Yes. In British Columbia, a hazardous materials survey (HMS) is legally required before any renovation, demolition, or restoration work on buildings constructed before 1990. This is mandated by WorkSafeBC regulations (OHS Regulation 20.112) to identify materials like asbestos, lead, mercury, PCBs, and silica that may pose health risks during work.

  • What does a hazardous materials survey include?

    A hazardous materials survey involves a detailed inspection and sampling of materials throughout the property. The surveyor tests for asbestos-containing materials (ACMs), lead-based paints, mercury, mould, silica, and other dangerous substances. A report is then produced outlining the location, type, condition, and recommendations for safe handling or removal.

  • What is asbestos, and why is it dangerous?

    Asbestos is a group of naturally occurring fibrous minerals that were widely used in construction materials for fireproofing, insulation, and strength. When disturbed, asbestos fibres can become airborne and, if inhaled, cause serious diseases such as asbestosis, mesothelioma, and lung cancer. These diseases can take decades to appear and are often fatal.

  • What happens if asbestos or lead is found during a survey?

    If asbestos or lead is found, a site-specific safe work procedure must be developed, and a removal plan must be implemented by licensed professionals before any construction work begins. A clearance inspection and air monitoring are typically required after remediation to confirm that the area is safe for re-occupancy or renovation.

  • Who can legally remove asbestos in BC?

    In BC, only qualified and trained professionals can legally remove asbestos. WorkSafeBC regulations require all asbestos abatement to be conducted by workers who are certified, and as of January 1, 2024, asbestos abatement contractors must be licensed by WorkSafeBC. DIY removal is highly discouraged and may be illegal under certain conditions.

  • How long does a hazardous materials survey take, and when should I schedule it?

    The duration depends on the size and complexity of the building but typically takes a few hours to one day for sampling, with lab results available in 1–2 business days. You should schedule the survey early in the planning phase of any project—before applying for permits or starting any demolition or renovation—to avoid delays and ensure compliance.
