Choose a Montreal contractor by verifying the appropriate licence, comparing written quotes for the same scope and checking recent work similar to your project. Before signing, clarify permits, insurance, payment stages and how changes will be approved. A low price or a polished website should not replace these checks.
Renovations involve more than selecting finishes. The contractor needs to understand the building, organize trades and explain what the proposed price includes. A careful selection process gives you a better chance of a workable schedule and reduces misunderstandings once walls are opened or materials are ordered.
Define the project before requesting quotes
Describe the result you want in practical terms. For a bathroom, identify whether fixtures stay in place, whether plumbing moves and whether the work includes ventilation or electrical changes. For a larger renovation, separate structural changes from cosmetic updates.
Prepare photographs, measurements and a list of known problems. State your priorities, such as accessibility, storage or reducing disruption. If drawings or professional design work are needed, establish who will provide them and when they must be ready.
Our Montreal renovation cost guide offers broader planning context. Use it to identify cost categories, then obtain project-specific quotes rather than treating a general estimate as a guaranteed price.
Verify the contractor’s licence
The Régie du bâtiment du Québec licence-checking guidance directs homeowners to its licence holders’ repertory. Verify the number yourself and confirm that the licence is valid and appropriate for the work being proposed.
Match the licensed business name with the name on the quote and contract. If the contractor uses a trading name, ask how it relates to the legal entity. A licence number copied onto a website is not enough on its own.
The RBQ also explains work requiring a licence. Where specialized trades or an unusual project are involved, ask the relevant authority to clarify the requirements. Do not accept a vague assurance that someone else’s licence covers every activity.
Ask about experience with your building type
A contractor experienced with new houses may face different conditions in an older Montreal duplex or condominium. Ask for examples involving comparable work, access constraints and occupied homes. Discuss any known history of leaks, settling or previous alterations.
Request recent references and ask specific questions. Was the site protected? Were changes explained before extra work started? Did the contractor communicate clearly when something affected the schedule? A useful reference goes beyond whether the finished room looked attractive.
Photographs can demonstrate finishes but may not show hidden work or who performed it. Ask what the contractor’s role was in each example. If possible, review projects with a similar scope rather than relying on an unrelated showcase renovation.
Compare written quotes on equal terms
Give each bidder the same scope and request a clear breakdown. Identify included materials, quantities, demolition, disposal, site protection and cleanup. Ask whether taxes and permits are included or separate.
Allowances deserve attention. A quote may include an assumed amount for fixtures or finishes while leaving the final choice open. Understand how spending above that allowance changes the price and whether handling or installation differences also apply.
| Quote item | What to clarify | Risk if omitted |
|---|---|---|
| Scope | Rooms, tasks and exclusions | Different expectations of completion |
| Materials | Products or clearly defined allowances | Unexpected upgrade charges |
| Site work | Protection, disposal and cleanup | Extra costs or avoidable disruption |
| Schedule | Start conditions and expected milestones | Unclear timing |
| Payment | Amounts linked to agreed stages | Payment ahead of documented progress |
| Changes | Written approval process | Disputes over additional work |
A higher quote may include work that a cheaper one excludes. Ask for explanations rather than assuming all contractors have priced the same project. Avoid comparing only the total at the bottom of the page.
Confirm permits and building approvals
Montreal requirements depend on the work and location. Consult the city’s permits and authorizations information and confirm requirements with the relevant borough. State in the contract who applies, pays and supplies necessary documents.
Condominium projects may also require approval from the syndicate and compliance with building rules. Elevator reservations, working hours and protection of common areas can affect the schedule. Discuss these conditions before selecting a start date.
A contractor’s availability does not mean all approvals are ready. Avoid ordering work that depends on a permit before understanding the authorization process. Include any professional drawings or assessments in your preparation plan.
Review insurance, payments and change orders
Ask for evidence of relevant insurance and clarify who is responsible for subcontractors. Explain your project to your own insurer if it changes occupancy or creates significant renovation exposure. Keep copies of documents with the contract.
Discuss payment milestones that reflect agreed progress or material commitments. Obtain receipts and keep a record of every payment. Be cautious if the payment recipient differs from the contracted business without a clear explanation.
Changes should record the revised work, price and schedule before proceeding. Hidden conditions can arise, but that does not remove the need for communication. Ask how the contractor will document a problem and present options when something unexpected is discovered.
Recognize red flags early
Pressure to sign immediately, refusal to provide a written contract and evasive answers about licensing warrant caution. So do inconsistent business details, unusually vague quotes or promises that every approval can be ignored.
A busy contractor is not necessarily a poor choice, but they should explain who will supervise and when the work can realistically begin. Ask how many projects run at once and whom you contact if a problem arises.
Before work starts, agree on access, dust control, security and daily cleanup. If you must stay elsewhere or move belongings, include those expenses in your planning. Our moving cost guide may help with that separate part of the project.
Frequently asked questions
How many quotes should I request?
Several comparable quotes can help you understand the scope and pricing. Quality matters more than collecting a large number of incomplete estimates.
Does a licence guarantee good workmanship?
No. Verify the appropriate licence, then assess references, communication, contract details and relevant experience as separate checks.
Should I always choose the lowest quote?
No. Compare inclusions, allowances, supervision and payment terms. The most useful quote is one that clearly prices the work you actually need.
