What drives the cost of general contracting
Project scope
The more trades involved, from demolition through framing, electrical, plumbing and finishing, the more coordination the contractor carries, and management is usually a percentage of the total build.
Design and permits
Projects that need drawings, engineering or a permit take more of the contractor time up front, and a good one prices that work in rather than surprising you later.
Finish level
Standard, mid-grade and high-end finishes change both material cost and the skill of the trades required, which moves the overall number substantially.
Site conditions
Older homes hide surprises like outdated wiring, rot or uneven framing, so a sensible contingency on top of the quote is normal on any larger renovation.
What's typically included
A general contractor typically handles project planning, permits, scheduling and supervising all subtrades, material coordination, site management, cleanup and a warranty on the completed work.
How to keep the cost down
Decide the full scope before work starts and resist mid-project changes. Change orders are the most expensive kind of decision, because they interrupt a schedule the contractor has already booked trades around.
What affects general contracting cost in Montreal
Contractor licensing
Most general contracting work in Québec must be done by a contractor holding a valid RBQ licence. Confirming the licence up front protects your warranty rights and is the first thing to check on any quote.
Permits
Renovations that touch structure, plumbing or electrical usually need a municipal permit in Montreal, and some boroughs add their own rules. Ask each contractor to confirm which permits your project needs and who pulls them.
Taxes
Québec quotes carry both GST (5%) and QST (9.975%), so build roughly 15% of tax into your budget on top of the ranges above.
Climate
Freeze-thaw winters make drainage, insulation and foundation detail especially important in Montreal, which can add cost but prevents far more expensive water damage later.

How much does general contracting cost in Montreal?
Montreal general contracting projects typically run between $5,000 and $300,000, though your final price depends on scope, materials, permits, and local labour rates in Quebec. The best way to pin down your number is to compare itemized quotes from verified Montreal contractors.
How much does General Contracting cost?
Most general contracting projects fall between $5,000 and $300,000, with the final number driven by scope, material grade, and finishes. Small refresh jobs land near the bottom of the range, while full-scale work with premium materials pushes toward the top. Treat the range as a starting point for budgeting, then confirm it with detailed quotes for your specific home; local labour rates in your city can shift the picture noticeably.
What affects the price?
Project size, material quality, structural changes, permits, and disposal all move the final number. Site condition matters too: hidden water damage, outdated wiring, or uneven framing discovered mid-job is the most common source of overruns, so a contingency of 10 to 20 percent on top of your quote is a sensible cushion. Getting several quotes remains the best way to learn your real cost before committing.
How do I get an exact price for my project?
Only a quote based on your actual home can give you a firm number. Post your project on NeedReno with a description and photos, and up to five verified local contractors will price it for free, with no obligation to hire. Comparing their itemized quotes side by side shows you both the fair market price and how each pro plans to approach the work.
How can I keep my general contracting cost down?
Scope discipline saves more than bargain hunting. Decide what you want before work starts, since mid-project changes are the most expensive kind, and consider keeping existing layouts where possible because moving plumbing or walls multiplies cost. Mid-grade materials often deliver most of the look at a fraction of premium pricing. Finally, compare multiple quotes: the spread between them is often thousands of dollars for identical scope.
Do these prices include permits and cleanup?
Ranges shown here reflect typical all-in project costs, but individual quotes vary in what they bundle. Always check whether permits, demolition, disposal, and final cleanup are itemized in each quote you receive; a low headline price that excludes them is not actually cheaper. A detailed, itemized quote is also easier to compare and a good sign of an organized contractor.
