Finishing your basement is one of the smartest ways to add space and value to your home. Whether you’re turning it into a family room, a home gym, or a rental suite, understanding the basement finishing cost in Montreal is essential before starting the project.
At Revohouse, we specialize in helping homeowners plan and complete beautiful, durable basement renovations across the Greater Montreal area. Let’s break down what impacts your project’s cost and how to budget effectively.
How Much Does Basement Finishing Cost in Montreal?
On average, finishing a basement in Montreal costs between $40,000 and $85,000, depending on the size, complexity, and finishes you choose.
Here’s a quick breakdown:
| Type of Project | Estimated Cost (CAD) | Description |
|---|---|---|
| Basic Finishing | $40,000 – $55,000 | Includes insulation, drywall, flooring, lighting, and basic paint. |
| Mid-Range Remodel | $55,000 – $70,000 | Adds better flooring, custom trim, and possibly a small bathroom. |
| High-End Basement | $70,000 – $85,000+ | Includes full bathroom, kitchenette, home theatre, or gym. |
💡 Tip: The cost per square foot usually ranges from $80 to $150, depending on design complexity and material choices.
Factors That Affect Basement Finishing Cost
Every basement renovation is unique, but these are the main factors that determine your total cost:
1. Size and Layout
The larger the basement, the higher the cost. However, larger spaces tend to have a lower cost per square foot, as some expenses (permits, labor setup, etc.) are fixed.
2. Design & Features
A simple recreation room will cost less than a luxury basement suite with plumbing, heated floors, or custom built-ins. Adding a bathroom or kitchenette can increase costs by $10,000–$25,000.
3. Plumbing and Electrical Work
Upgrading or rerouting plumbing and electrical systems is often necessary for older Montreal homes. That can add $5,000–$10,000 to your project, depending on scope.
4. Finishes and Materials
Your choice of flooring, lighting, and wall finishes plays a big role in the final price. Vinyl plank flooring is durable and affordable, while hardwood or engineered wood options will increase the total cost.
5. Permits and Inspections
In Montreal, you usually need a renovation permit for major basement work. Permits ensure your project meets building codes and safety standards. Learn more in our full guide:

How to Budget for a Basement Renovation
Planning ahead prevents stress and unexpected costs. Here’s how to budget wisely:
| Budget Item | Percentage of Total | Notes |
|---|---|---|
| Materials & Finishes | 40–45% | Flooring, walls, paint, lighting |
| Labor | 35–40% | Skilled trades, installation |
| Permits & Design | 10% | City permits and professional design |
| Contingency | 10–15% | For unexpected changes or upgrades |
Set aside an extra 10% buffer for unforeseen issues like plumbing upgrades or hidden foundation repairs.
