Lead paint

Paint made before lead was restricted can contain lead. Canada limited lead in interior consumer paint in 1976 and tightened it further over the following decades, so it's mainly a concern in homes built before about 1980 — on walls, trim, doors, windows, railings, and exterior surfaces, often buried under newer coats.

Why it matters

Lead is a neurotoxin, and the people most at risk are young children and pregnant women, for whom even low exposure can affect development (Health Canada). The danger isn't usually intact, well-maintained paint — it's lead dust and chips, created when old paint is sanded, scraped, or rubs at friction points like windows and doors, or when it's peeling. That makes it both a health issue and a renovation-planning issue in older homes.

How to spot it

You can't tell lead paint by sight — a test kit or a lab/XRF test confirms it. Treat as suspect: any pre-1980 home, especially peeling or chipping paint, layers under newer paint, and painted windows and doors. Chalking, peeling, or chipping paint in an older home is the flag worth acting on.

What it costs

A consumer test kit is cheap (~$20–40); a professional lab or XRF test costs more. Managing it ranges widely: keeping paint intact and repainting (encapsulation) is low-cost, while lead-safe renovation or professional removal of larger areas runs into the thousands depending on scope and the safety controls required.

What to do

Don't dry-sand, scrape, or torch old paint yourself — that's what creates hazardous dust. If the paint is intact, maintaining and repainting it is often enough. Before renovating a pre-1980 home, test first and use lead-safe work practices or a qualified contractor, and keep children away from any disturbed area. If you have a health concern — especially about a child's exposure — talk to your doctor or public-health unit; testing blood-lead levels is simple.

Education and triage, not a home inspection. Casaroo flags pre-1980 homes and peeling paint worth testing — only a test confirms lead, and disturbing it safely needs lead-safe practices or a qualified professional. We flag; we don't certify.

Risk depends on the paint's condition and exposure; for health concerns consult a medical or public-health professional. Casaroo flags, it does not inspect.
