How to Choose the Right General Contractor in Montreal

The single biggest factor in how a renovation actually goes isn't the size of your budget or the complexity of your project - it's who you hire to run it. A good general contractor coordinates every trade, catches problems before they become expensive, and keeps you informed without you having to chase updates. A poor fit can turn even a modest project into a stressful, drawn-out experience. Here's what to actually look at before you sign a contract.

Questions to ask every contractor you're considering

A short phone call or first meeting tells you a lot about how a contractor operates. These are the questions worth asking directly.

• How do you handle permits, and who applies for them?
• Who will be my main point of contact during the project - you, a project manager, or whoever is on-site that day?
• How do you handle changes or unexpected issues once work has started?
• What does your payment schedule look like, and what triggers each payment?
• Can I see examples of past projects similar in scope to mine?
• How do you protect the rest of my home during construction?
• What happens if the timeline changes - how and when will I be told?

Pay attention not just to the answers, but to how directly they're given. A contractor who is vague or defensive about payment schedules, timelines, or past projects during the sales conversation is unlikely to communicate more clearly once the contract is signed.

Licenses and insurance

In Quebec, contractors performing construction work above certain thresholds are required to hold a valid RBQ (Régie du bâtiment du Québec) licence. Before hiring anyone, ask for their RBQ licence number and verify it directly through the RBQ's public registry - this confirms the licence is active and shows what category of work it covers, since licences are issued for specific trades and project types.

Beyond licensing, ask for proof of liability insurance and confirm it's current. This protects you if something is damaged during construction. If a contractor is using subcontractors, it's also worth asking whether those subcontractors carry their own insurance and, where applicable, their own licensing - responsibility can get complicated if something goes wrong and only the general contractor was insured.

Communication style

A renovation involves weeks or months of decisions, and how a contractor communicates during the estimate process is usually a preview of how they'll communicate during construction. Do they respond to questions promptly? Do they explain their reasoning when you ask about a material or a step in the process, or do they brush past the question? Do they proactively flag potential issues, or only mention them once they've already become a problem?

Ask directly how updates will be handled once work begins. Some contractors provide a single dedicated project manager as your point of contact. Others expect you to coordinate directly with whichever trade is on-site. Neither approach is inherently wrong, but you should know which one you're getting before you commit.

Scope and timeline clarity

A trustworthy estimate spells out exactly what's included - materials, labour, permits, cleanup, and disposal - and just as importantly, what's excluded. If a quote is a single lump sum with no breakdown, ask for one. You should be able to understand what you're paying for before you commit, not discover it partway through the project.

The same goes for timeline. A contractor should be able to give you a realistic project schedule, including how permit approval time and material lead times factor in - not just the number of days the physical construction will take. Ask what happens if the timeline shifts, and how you'll be informed if it does.

How to evaluate quotes

When comparing quotes from different contractors, resist the urge to simply rank them by total price. Two quotes for the "same" kitchen renovation can assume completely different scopes, materials, and inclusions. Before comparing numbers, make sure you're comparing the same project.

1. 1Confirm each quote covers the same scope of work.
2. 2Check whether permit fees are included or separate.
3. 3Ask about the specific materials and finish levels assumed in each quote.
4. 4Look at what's excluded, not just what's listed.
5. 5Ask how each contractor would handle a scope change or unexpected issue, and whether that process is defined in writing.

References and past work

Ask for references from projects similar in scope to yours, not just any past client. A contractor who does excellent bathroom refreshes isn't automatically the right fit for a full home renovation or a home addition. When you speak with a reference, ask specifically about communication during the project, how changes or surprises were handled, and whether the final result matched what was promised at the estimate stage.

Red flags to watch for

A few warning signs are worth taking seriously, even if everything else about a contractor seems fine on the surface.

• Reluctance to provide RBQ licence or insurance documentation
• Requesting a large upfront deposit before any work or materials are committed
• A verbal-only agreement with nothing in writing
• Pressure to sign quickly, especially with a discount tied to an immediate decision
• Vague answers about permits, or a suggestion that permits aren't needed without a clear explanation why
• No fixed address or verifiable business presence
• Quotes that seem significantly lower than others with no clear explanation for the difference

None of these signs alone is automatically disqualifying, but more than one should prompt a closer look before you sign anything. For more on how quote comparisons and rushed decisions commonly go wrong, see our article on common renovation mistakes to avoid.

Bringing it all together

Choosing a general contractor is ultimately about trust and clarity: do they explain things clearly, back up their claims with documentation, and give you a realistic picture of scope, cost, and timeline before you commit? Take the time to ask the questions above, verify licensing and insurance directly, and compare quotes on equal footing. It's worth the extra week or two of vetting to avoid months of frustration.
