Do cleaning companies need hazardous waste certification for lead paint cleanup in Ontario?

Lead paint dust from a renovation is a real health concern, and cleaning it up properly takes more than a regular post-construction clean. There is no single, simple certificate that tells you a cleaning company is qualified for lead work, so the useful approach is to ask specific questions about training, methods and insurance.

What to Ask About Lead Paint Cleanup

Older homes can have lead-based paint somewhere under newer layers. When that paint is sanded, scraped, demolished or even cleaned aggressively, the resulting dust can be hazardous, particularly for children and pregnant people. If you are not sure whether paint in your home contains lead, ask about having it tested before work starts.

Ask any cleaning company whether its crew has specific experience and training in lead dust cleanup, how they protect their workers, and how they keep dust from spreading to the rest of the house. Ontario has workplace rules for work involving lead, and an experienced company should be able to explain how it follows them.

Good lead cleanup practice generally includes containment with plastic sheeting, HEPA vacuums, wet cleaning methods that keep dust from becoming airborne, protective clothing and respirators for the crew, and some way of checking that the area is clean afterwards. Dry sweeping or using an ordinary household vacuum on lead paint debris is risky, because it spreads fine dust through the home where it settles on surfaces and can be swallowed, especially by young children.

Ask how the debris will be bagged and where it will go. Lead-contaminated debris should not simply be mixed into general construction waste; ask the company how they dispose of it, and check the City's household hazardous waste options for any small quantities you handle yourself.

Ask for proof of liability insurance and what it covers — and specifically whether hazardous materials work is covered, because some policies exclude it. If your renovation has disturbed lead paint in an older home, this is not a DIY cleanup; the health risks are too significant to handle without the right equipment and training.

The Ottawa Construction Network directory at justynrookcontracting.com lists companies across multiple trades. For lead-related work you may need an abatement specialist in addition to a cleaning company, so ask each one where their work stops and the other's begins.
