The Ranking

Our top 6 general contractors in Montreal

Montreal's housing stock sets the work. Plexes, duplexes and triplexes in the Plateau, Rosemont and Villeray, brick bungalows in LaSalle and Saint-Laurent, and post-war homes in Notre-Dame-de-Grâce all come with old structure, tight lots and borough rules. A general contractor earns its fee when a job crosses trades: opening a wall between a kitchen and a living room, lifting a roof for a second storey, converting a plex into a single-family house, or gutting a floor after water damage. Those projects usually need drawings, an engineer, a permit and a crew that can coordinate plumbing, electrical, framing and finishes. In Quebec a contractor must hold a licence from the Régie du bâtiment du Québec (RBQ) with the subclass that matches the work, and you can search any number on the RBQ website before you sign. Construction trades are also regulated by the Commission de la construction du Québec (CCQ), and electrical and plumbing work must be done under a master electrician or master plumber. Permits come from your borough, not from the province, so ask your contractor in writing who applies, who pays the fee and whether an architect or engineer must stamp the plans. New homes carry a separate rule: builders of new residential buildings must join the Garantie de construction résidentielle (GCR) plan. Licence numbers shown here are the ones each company publishes on its own site, and we did not confirm them on the RBQ register, so please do that yourself. Several of these firms also appear in our Montreal home remodeling ranking, because the best general contractors in the city are also its busiest renovators. Here they are judged on the broader job: structure, additions, permits and whole-home work. Each profile says what the company publishes about licensing, warranty and insurance, and what you should ask for.

Methodology

How we chose the best general contractors in Montreal

We read Google Maps results for "general contractor in Montreal, QC", "general contractor company Montreal" and "design build contractor Montreal" on October 31, 2026, then ran extra searches in French and by borough, including the Plateau, Rosemont, NDG, Westmount, Outremont, Verdun, Ahuntsic, Saint-Laurent, LaSalle and Lachine. Each company had to be operating, rated 4.5 or higher from at least 50 Google reviews, and show a street address inside the City of Montreal or one of its boroughs, a working website, a real logo and real project photos. We rejected an office outside the city (Dorval), a lead-generation site with 950 reviews, a custom furniture maker, a condo-only specialist, a firm whose website would not load after two tries, companies with no website or too few reviews, and renovators that only do painting or kitchens and baths. The order follows Google's results, with Espé Montréal and RÉNO M3 placed by their positions in our design-build and borough searches. DCR, Constructeurs De Qualité, Dargis and Espé are also listed in our home remodeling ranking, because few Montreal general contractors meet the review bar. Licence numbers are as published on each company's own site and were not checked on the RBQ register. No company paid for a place on this list. Ratings and review counts were read on October 31, 2026.

Hiring

How to choose a general contractor in Montreal

  1. Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  2. Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  3. Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  4. Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  5. Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  6. Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  7. Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  8. Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

FAQ

General contracting companies in Montreal FAQs

How do I check a Montreal general contractor's licence?

Search the contractor's number in the Régie du bâtiment du Québec (RBQ) licence lookup and confirm the licence is valid with the subclass that matches your work. Ask for proof of insurance, and for any new home ask whether the builder is enrolled in the GCR warranty plan. All six companies here print an RBQ number on their own sites, but we did not confirm any of them on the register, so check each one yourself before you sign.

How much does a general contractor cost in Montreal?

It depends on scope, structure and finishes, and none of these companies publishes a full price list. RÉNO M3's contact form starts its budget ranges at 40,000 dollars, and Espé Montréal sells a fixed-price package. Ask each contractor for a written itemized quote that separates labour, materials, permits, engineering and allowances, and compare at least two quotes for the same scope.

Do I need a permit to remove a wall or add a floor in Montreal?

Usually yes for structural changes. Montreal's boroughs issue building permits, and removing a load-bearing wall, adding a storey or converting a plex generally needs drawings and often an engineer or architect. Ask your contractor in writing who applies, who pays the fee, and check the rules with your borough office before work starts. Ecosense Renovation, Dargis and RÉNO M3 each say they coordinate engineering or plans.
