Asbestos and hazmat abatement covers the safe removal, containment, and disposal of hazardous materials before a demolition or renovation job starts. In Oakville that usually means asbestos insulation, vermiculite, floor tile mastic, or pipe wrap found in homes built before the early 1990s, along with materials like lead paint, mold-damaged drywall, or contaminated soil on older commercial sites. This work is regulated in Ontario under O. Reg. 278/05, which sets rules for containment, air monitoring, worker protection, and disposal at licensed facilities.
We list 13 companies in Oakville that handle this kind of work, ranging from small residential abatement crews to larger outfits that pair hazmat removal with full demolition and excavation.
What to check before you hire
- A current WSIB clearance certificate and liability insurance specific to hazmat work
- Experience with the type of asbestos work you need (Type 1, 2, or 3 under Ontario rules)
- A written scope that includes air quality testing and a disposal manifest showing where materials went
- Proper containment setup: negative air pressure, sealed work areas, and decontamination procedures for crews
