Lead was a common ingredient in paint for much of the twentieth century. Many character homes in Vancouver, Burnaby and New Westminster still have layers of lead paint hidden under newer coats. It is usually safe while intact, but sanding, scraping or demolition can create toxic dust. Lead paint testing tells you exactly where the risk is.
Is My Home at Risk?
Health Canada advises that homes built before 1960 likely contain lead-based paint, and homes built between 1960 and 1990 may contain some lead paint, particularly on exterior surfaces, trim and windows. Older plumbing can also contribute lead to drinking water.
Why Lead Is Harmful
Lead has no known safe level of exposure. Young children and pregnant people are most at risk because lead can affect brain development, learning and behaviour. Adults can also experience health effects with repeated exposure. Most exposure in homes comes from dust created when lead paint deteriorates or is disturbed.
Where Lead Is Commonly Found
- Window frames, sills and sashes, where friction creates dust
- Doors, door frames and baseboards
- Stairs, railings and porches
- Exterior siding and trim
- Soil around the foundation, from years of weathering paint
- Older plumbing, solder and service lines
Types of Lead Testing
Paint chip sampling
Small samples through all paint layers are analyzed in an accredited lab to measure lead content accurately.
Dust wipe sampling
Wipes from floors and window sills show whether lead dust is present in living areas, which is especially important for homes with young children.
Soil sampling
Useful for gardens and play areas near older homes.
Water testing
Health Canada's guideline for lead in drinking water is 5 micrograms per litre. Testing tap water is a simple way to check older plumbing.

Lead Testing Before Renovation
If you plan to replace windows, refinish trim, sand floors or open walls in an older home, test first. Results guide contractors on dust controls and help you decide whether professional lead removal is needed. In many older homes, lead testing is completed alongside asbestos testing.
Everyday Tips While You Wait for Results
- Do not dry sand, scrape or heat-strip painted surfaces
- Clean window sills and floors with damp cloths rather than sweeping
- Wash children's hands and toys frequently
- Run cold tap water for a few minutes before drinking if pipes are old
Frequently Asked Questions
Are home lead test swabs reliable?
They can give a quick indication, but they can miss lead under newer paint layers. Lab analysis gives a definitive answer.
Is lead paint safe if it is painted over?
Intact paint in good condition is lower risk, but friction surfaces and any renovation work can still release dust.
How quickly can I get results?
Lab results are usually available within a few business days.
