What should I check before hiring a renovation contractor?

Before hiring any renovation contractor, verify their licensing, insurance, and references while getting detailed written estimates from at least three professionals. This upfront research protects you from costly mistakes, delays, and potential legal issues down the road.

Essential Verification Steps

Start by confirming the contractor holds proper licensing for your project type. In Ontario, electrical work requires contractors to use ESA (Electrical Safety Authority) licensed electricians, while gas work must be performed by TSSA (Technical Standards and Safety Authority) certified technicians. General contractors should be registered with the province and carry WSIB coverage. Request to see these credentials directly - legitimate professionals will provide them without hesitation.

Insurance verification is equally critical. Your contractor needs both liability insurance ($2+ million is standard in the GTA) and WSIB coverage. Call their insurance company directly to confirm active coverage - don't just accept a certificate that could be expired or fraudulent. This protects you if someone gets injured on your property or if work damages your home.

Financial and Reference Checks

Get detailed written estimates from at least three contractors, ensuring each quote covers the same scope of work. Toronto-area renovation costs typically run 10-20% higher than other Ontario markets, so expect bathroom renovations from $18,000-$60,000 and kitchen projects from $30,000-$100,000 depending on size and finishes. Be wary of estimates significantly below market rates - they often indicate corners will be cut or change orders will inflate the final cost.

Contact recent clients directly, asking to see completed work if possible. Quality contractors are proud to share references and examples of their craftsmanship. Ask previous clients about timeline adherence, cleanliness, communication, and how any issues were resolved.

Contract and Permit Considerations

Never proceed without a detailed written contract specifying materials, timeline, payment schedule, and change order procedures. In Toronto, avoid contractors demanding large upfront payments - legitimate professionals typically request 10% down with progress payments tied to completion milestones. The contract should clearly state who obtains permits and inspections.

Verify the contractor will pull proper permits through the City of Toronto Building Division. Unpermitted work creates insurance issues, resale problems, and safety risks. Major renovations require building permits, while electrical and plumbing work needs separate trade permits and ESA/city inspections.

Red Flags to Avoid

Be cautious of door-to-door solicitors, cash-only deals, or pressure tactics demanding immediate decisions. Legitimate contractors don't need to rush you into signing. Similarly, avoid anyone without a permanent business address, proper insurance, or reluctance to provide references.

Next Steps

Once you've verified credentials and compared quotes, trust your instincts about communication and professionalism. The lowest bid isn't always the best value - focus on contractors who demonstrate expertise, proper licensing, and strong references.
