Read moreOntario (ON) does not currently require a state-level license for restoration contractors. When hiring for basement waterproofing in Ajax, this means there is no state oversight verifying contractor qualifications — making your own due diligence even more critical. Look for contractors who voluntarily carry general liability insurance, are bonded, and can provide proof of workers' compensation coverage.
Ask for IICRC certification numbers and verify them at iicrc.org. Request proof of pollution liability insurance specifically — standard general liability does not cover hazardous material incidents. Check that the company has experience with your specific type of damage and can provide references from similar projects.
Local municipalities in the Ajax area may still require permits for certain restoration jobs. Ask your contractor about permit requirements before work begins.

Restoration companies should carry general liability insurance ($1M minimum), workers compensation, pollution liability insurance for hazardous materials, and professional liability coverage. For sewage and mold work, additional biohazard liability coverage is essential.
Improper restoration work can leave hidden moisture causing structural rot, spread mold spores throughout the home, expose occupants to toxic soot particles, or result in denied insurance claims worth tens of thousands of dollars. Unlicensed hazardous material handling violates OSHA regulations and environmental laws.
Restoration sites contain serious hazards: structural instability after fire, toxic soot and ash particles, black mold spores, sewage pathogens (E. coli, hepatitis), asbestos in older homes disturbed by damage, and electrical hazards from water-damaged wiring. Never enter a fire or flood-damaged structure without professional clearance.
