Finishing your basement is one of the smartest ways to add space, comfort, and value to your home. For homeowners in Montreal, basement renovations have become increasingly popular — whether it’s turning an unused area into a cozy family room, an income suite, or a private gym.
But before you start planning your dream basement, the big question arises:
How much does it cost to finish a basement in Montreal?
At Revohouse, we’ve helped hundreds of Montreal homeowners design and complete stunning basement spaces. This guide breaks down the average basement finishing cost in Montreal, explains what factors affect the price, and gives you practical budgeting tips.
What Determines the Cost of Basement Finishing?
Every basement project is unique. The total basement remodel price in Montreal depends on a mix of structural, material, and design factors, including:
-
Basement size: A 600 sq. ft. space will obviously cost less to finish than 1,200 sq. ft.
-
Existing conditions: Moisture, cracks, or insulation issues can increase prep costs.
-
Purpose of the space: A simple playroom is cheaper than a full apartment suite with a bathroom and kitchen.
-
Material quality: Flooring, drywall, ceiling finish, and lighting choices all influence the final cost.
-
Plumbing and electrical: Adding a bathroom or laundry area adds complexity.
-
Permits and labor: Montreal’s permit requirements and skilled labor rates must be included in your budget.
💡 Example: One homeowner in Côte-Saint-Luc transformed their unfinished basement into a family media room for $25,000, while another in Beaconsfield added a guest suite and bathroom for $45,000.
