The First Domino in Every Demolition
Nothing about a demolition proceeds until the hazardous materials survey exists. The municipality wants it before issuing the permit. The demolition contractor's insurer and WorkSafeBC require it before machines arrive. The abatement contractor prices their work from it. Order it late and every one of those steps waits on you; order it early and it's the cheapest, fastest line item on the whole project.
We perform complete pre-demolition hazardous materials surveys across the Fraser Valley — houses, barns, shops, and commercial structures — with reports written to satisfy WorkSafeBC requirements and the permit desks of Abbotsford, Chilliwack, Mission, Langley and the FVRD electoral areas.
What a Full Survey Involves
Unlike a renovation survey, a pre-demolition survey covers the entire structure, because all of it will be disturbed:
- Interior finishes — drywall systems, plaster, ceiling textures, flooring layers and mastics
- Insulation everywhere it hides — attics (vermiculite), walls, ducts, pipes, boilers
- Exterior — stucco, siding, cement board, roofing layers, window putty
- Mechanical rooms, crawlspaces and outbuildings
- Other regulated materials: lead paint, mercury switches, ozone-depleting refrigerants, PCB ballasts
Each material is sampled, logged by location, and analyzed at an accredited BC lab. The report inventories every hazardous material in the structure with enough detail that abatement contractors can bid the removal accurately — which protects you from both lowball surprises and padded quotes.
The Demolition Compliance Path
- Survey & report — we identify and document all hazardous materials.
- Abatement — a WorkSafeBC-licensed contractor removes the identified materials.
- Clearance — independent air and clearance testing confirms removal is complete.
- Demolition — with documentation in hand, your permit is released and the excavator goes to work.
Frequently Asked Questions
Is a survey required to get a demolition permit?
Fraser Valley municipalities build hazardous-materials documentation into the demolition process, consistent with WorkSafeBC requirements — specifics vary by city, so confirm with your permit desk. Either way, WorkSafeBC independently requires hazardous materials to be identified before demolition work, and the pre-demolition survey report is the document that starts that chain.
How is this different from a renovation survey?
Scope. A renovation survey covers only the areas your project disturbs; a demolition survey must identify hazardous materials throughout the entire structure, inside and out, because everything is coming down. More materials, more samples, more thorough — and priced accordingly.
What does a pre-demolition survey cost?
For a typical Fraser Valley house, expect $600–$1,000 depending on size, construction era, and the number of distinct materials. Outbuildings, additions, and mixed construction add samples. Firm quote before we start, always.
The house is a teardown — why does anyone care what’s in it?
Because demolition releases whatever the building contains. Asbestos fibres from an uncontrolled demo drift across neighbouring properties and expose workers, which is why regulators treat teardowns more strictly than renovations, not less.
Can you also handle the abatement?
We are independent testers — we don’t remove asbestos, which keeps our surveys honest. What we can do is refer licensed abatement contractors, then return for independent air and clearance testing so you have third-party proof the site is clean.
