How do I verify a contractor's past work?

Verifying a contractor's past work is essential for protecting your investment and ensuring quality results. Start by requesting a portfolio of recent projects similar to yours, along with at least 3-5 recent client references you can contact directly.

Portfolio and Reference Verification
Ask to see photos of completed projects, ideally with before-and-after shots that demonstrate the contractor's capabilities. Quality contractors are proud of their work and readily share examples. When contacting references, ask specific questions about work quality, timeliness, cleanliness, communication, and whether they'd hire the contractor again. Don't just rely on testimonials on their website – speak directly with past clients.

Digital Verification Methods
Check online reviews across multiple platforms including Google Reviews, HomeStars, and Better Business Bureau. Look for patterns in feedback rather than focusing on individual reviews. A few negative reviews among many positive ones is normal, but pay attention to how the contractor responds to complaints. Professional contractors address concerns constructively.

Physical Site Visits
The best verification is seeing completed work in person. Ask if you can visit a recent project site (with the homeowner's permission) or drive by completed exterior work. This allows you to assess quality, attention to detail, and how well the work has held up over time. Many reputable contractors can arrange brief site visits for serious potential clients.

Toronto-Specific Verification
In the GTA, verify that electrical contractors are ESA-licensed (Electrical Safety Authority) and HVAC contractors hold TSSA certification (Technical Standards and Safety Authority). Check the City of Toronto's permit database to confirm the contractor has pulled proper permits for similar projects. Licensed contractors should readily provide their license numbers for verification.

Professional Credentials and Insurance
Request proof of WSIB coverage and liability insurance (minimum $2 million is standard in Toronto). Verify business registration through the Ontario Business Registry. Established contractors typically belong to trade associations like the Greater Toronto Home Builders' Association or relevant trade organizations.

Red Flags to Avoid
Be wary of contractors who can't provide local references, only show photos without addresses, refuse site visits, or pressure you to sign immediately. Door-to-door solicitors and contractors demanding full payment upfront are typically problematic.

Next Steps
Take time to verify credentials before signing any contract. A reputable contractor will appreciate your due diligence and provide the information readily.
