What questions should I ask a contractor before hiring them?

Before hiring any contractor, ask targeted questions about their licensing, insurance, references, and project approach to ensure you're working with a qualified professional who will deliver quality work on time and within budget.

The most critical questions fall into several key areas that will reveal whether you're dealing with a reputable contractor or someone to avoid. Start with the fundamentals that protect you legally and financially, then dig into their experience and approach to your specific project.

Licensing and Legal Requirements
Ask to see their business license, WSIB coverage, and liability insurance certificates. In Ontario, electrical contractors must be ESA-licensed, and gas work requires TSSA certification. Don't just ask if they have insurance - request to see current certificates and verify coverage amounts. A legitimate contractor will provide these documents immediately. For larger projects, ask if they're registered with Tarion (new home warranty program) if applicable.

Experience and References
Request three recent references for similar projects and actually call them. Ask how long they've been in business and specifically how many projects like yours they've completed in the past two years. A contractor specializing in kitchen renovations might not be your best choice for basement waterproofing. Ask to see photos of recent work, and if possible, visit a current job site to observe their work quality and site cleanliness.

Project Planning and Timeline
Get specific about their timeline and what factors might cause delays. Ask how they handle change orders, material delays, and weather issues (crucial for Toronto's unpredictable climate). Find out their typical work schedule - do they work multiple jobs simultaneously or focus on one project at a time? Understanding their approach helps set realistic expectations.

Permits and Code Compliance
Ask who handles permit applications and whether permit costs are included in their quote. In Toronto, building permits can take 10-20 business days for simple projects, so factor this into your timeline. Verify they understand Ontario Building Code requirements for your specific project. Red flag: any contractor who suggests skipping permits to save money.

Pricing and Payment Structure
Never pay large amounts upfront - legitimate contractors typically request 10-15% down with progress payments tied to completion milestones. Ask for a detailed written estimate breaking down materials, labor, and other costs. Understand what's included versus excluded, and how they handle cost overruns. Get clarity on who purchases materials and whether you benefit from contractor discounts.

Communication and Problem Resolution
Ask about their communication style and frequency of updates. Who's your main contact - the owner or a project manager? How do they handle problems or disputes? Understanding their warranty policy is crucial - what's covered and for how long?

Toronto-Specific Considerations
For Toronto projects, ask about their experience with century homes if relevant, as these require specialized knowledge of heritage requirements and older building systems. If you're in a condo, verify they understand board approval processes and building-specific restrictions.

Next Steps
Get everything in writing before signing any contract. Compare at least three detailed quotes, checking references for each contractor. Remember, the lowest bid isn't always the best value - factor in experience, reputation, and your comfort level with their professionalism. Trust your instincts; if something feels off during initial meetings, it likely won't improve once work begins.
