Most drywall repairs look small: a doorknob hole, a crack over a door, a stain under a leaky window. In an older house, each one can mean cutting or sanding, and that is where asbestos becomes a question. This guide covers what WorkSafeBC says, how testing works, and where my part of the job starts.
Does drywall in older BC homes contain asbestos?
It can. WorkSafeBC says that if your home was built before 1990, it is likely that at least some parts of it contain asbestos. Its homeowner page lists drywall and textured ceiling coat among the usual places. Its drywall page adds that old drywall mud and some gypsum boards can contain asbestos.
You cannot see it. WorkSafeBC notes that asbestos is hard to spot because it is often mixed with other materials. When those materials are cut or sanded, fibres can get into the air. WorkSafeBC warns that breathing them can cause asbestosis, mesothelioma and other lung cancers.
Canada's ban on the import, sale and use of asbestos products came into force on December 30, 2018. The federal government is clear that it does not cover asbestos already built into a building. For a home repair, WorkSafeBC's 1990 line is the one to go by.
Which homes need an asbestos test before drywall repair?
WorkSafeBC tells homeowners, strata councils and property managers to get a home tested before a renovation or demolition project. For maintenance or repairs, it says you also need a qualified person to make an inventory of any asbestos present. A drywall repair in a pre-1990 home falls under that advice.
In practice, test before any job that cuts or sands the old wall or ceiling. That includes cutting out a water-damaged section, opening a wall, and sanding a crack back to a sound edge.
Every job I take gets a written scope before I start, so the price is agreed in advance and the list stays the list.

Can a handyman patch drywall in a pre-1990 house?
Yes, once the wall has been tested and the report shows no asbestos in the materials the repair will touch. Then it is ordinary drywall repair, and that I do. If the report finds asbestos in that wall or its mud, the work that disturbs it is abatement. WorkSafeBC says anyone you hire to deal with asbestos in your home must be licensed to do that work in BC. Abatement is outside what I do.
Until you have a report, follow WorkSafeBC's drywall page: if you suspect asbestos in old gypsum board, do not touch it or move it. My advice to homeowners is the same. No sanding, cutting or scraping until the results are back. If the repair is for a crack that keeps coming back, why drywall cracks keep coming back explains the usual causes while you wait.
How do you get drywall tested in the Lower Mainland?
Hire a licensed asbestos surveyor. WorkSafeBC counts identifying possible asbestos and collecting samples for someone else as asbestos abatement work, and it names surveyors among those who need a licence. The surveyor samples the materials the repair will touch, sends them to a lab, and gives you a written report.
Check the name first. Since January 1, 2024, asbestos abatement contractors must be licensed to operate in BC. WorkSafeBC's Asbestos Abatement Licence (AAL) Registry on worksafebc.com shows who holds a valid licence and flags any that are expired, cancelled, suspended or refused. WorkSafeBC also advises getting an up-to-date clearance letter for the contractor before work starts.
Keep the report and share it with whoever does the repair. It shows which materials were tested and what each one contained.
What happens if the test comes back positive?
WorkSafeBC's steps for homeowners are to hire a licensed abatement contractor to safely remove or contain the materials the survey found. Get that quote first, because it sets the order of work. It is a separate bill from the drywall repair.
Once the abatement is done and cleared, new drywall goes up and gets taped, mudded and painted like any other repair. My guide to popcorn ceiling removal in BC follows the same order for a textured ceiling: test, abate if needed, then finish.
What drives the cost of drywall repair in an older home?
I publish one price: the $200 minimum per job. In a pre-1990 home the total can have three parts, each billed by whoever does it:
- The asbestos survey and lab test, from a licensed surveyor.
- Any abatement, from a licensed abatement contractor.
- The drywall repair itself, priced on size, texture, wall or ceiling, and paint matching.
What drives drywall repair cost covers that third part in detail. I repair drywall across the valley, including drywall repair in Surrey, drywall repair in Langley and drywall repair in Abbotsford.
