Protect yourself from unreliable contractors. Watch for these warning signs:
- No written contract or quote. Everything should be documented before work begins.
- Demanding full payment upfront. Standard practice is a deposit (10-30%) with progress payments. Never pay 100% before work is complete.
- No insurance or WSIB coverage. If a worker is injured on your property and the contractor lacks coverage, you could be liable.
- Pressure to sign immediately. A reputable contractor gives you time to review a quote and compare options.
- No physical address or permanent phone number. Fly-by-night operators use temporary contact info.
- Significantly lower quote than competitors. If one quote is 40%+ below others, ask why. Cheap often means cutting corners.
