Planning a demolition project in Montreal? Whether you’re tearing out drywall, removing a garage, or demolishing an entire house, the costs can vary dramatically depending on the size, structure, materials, and permit requirements. In this article, we’ll break down the cost of demolition in Montreal by project type—so you can budget smarter and avoid surprise expenses.
What Impacts Demolition Cost in Montreal?
The average demolition job in Montreal ranges from $1,500 to over $50,000, but it’s not just about square footage. Here’s what typically affects pricing:
- Project type (interior vs. full structural)
- Accessibility (urban vs. suburban lots)
- Material types (concrete, brick, drywall, steel)
- Hazardous materials (asbestos, lead, mold)
- Waste disposal and transportation
- Permit and inspection fees
Montreal also has specific borough-level regulations, which may require demolition permits and environmental controls for larger tear-downs.
Interior Demolition Cost (Kitchen, Bathroom, Walls)
Interior demolition involves tearing out non-structural components—like drywall, flooring, cabinets, and ceilings—while preserving the outer structure of the home. It’s often part of a renovation or space reconfiguration project.
| Type | Average Cost (2025) |
|---|---|
| Drywall removal | $2.50 – $4.50/sq. ft. |
| Bathroom demolition | $1,200 – $2,500 |
| Kitchen demo (with cabinet removal) | $1,800 – $3,800 |
| Basement gut | $3,000 – $6,000 |
These rates typically include labor, dust barriers, basic disposal, and tool costs. Expect higher fees for concrete floors, tile, or mold remediation.
Garage Demolition Cost
Garage demolition in Montreal depends heavily on whether it’s attached or detached, the foundation type, and the building material. Wooden garages cost less to remove than cinderblock or concrete structures.
- Detached wood-frame garage: $2,500 – $5,000
- Concrete or brick garage: $6,000 – $12,000
- Attached garage (partial demolition): $4,000 – $9,000
Permits and structural engineering may be required, especially for attached units. Most jobs include cleanup and hauling of all materials, though foundation removal is usually priced separately.
Full House Demolition Cost in Montreal
When renovations aren’t worth the investment, some homeowners opt for full residential demolition in Montreal. This process involves total teardown of a single-family home, including foundation removal and waste management.
Cost Ranges:
- Wood-frame bungalow (1,200 sq. ft.): $18,000 – $26,000
- Two-storey home (2,000+ sq. ft.): $25,000 – $45,000
- Foundation removal (add-on): $4,000 – $12,000
Costs rise with limited access, historic designations, or hazardous materials. In some Montreal boroughs, you’ll need special permission to demolish if the home is over 50 years old or sits on a heritage lot.
Commercial or Multi-Unit Demolition Cost
DemoPrep also handles small-scale commercial and multi-unit residential demolition in the Greater Montreal area. These projects are priced individually but typically range from $12 to $35 per sq. ft. depending on:
- Building height and access
- Hazardous material requirements
- Urban constraints (permits, noise, traffic control)
Permit & Disposal Fees in Montreal
Montreal demolition projects require disposal planning. Expect the following additional costs:
- Permit fees: $100 – $1,200 (depending on borough and scope)
- Disposal bins: $350 – $650 per 10-yard bin
- Asbestos testing: $300 – $700 (if required)
Always check with your borough. DemoPrep includes most permitting and disposal in our quotes, so you’re not stuck with surprise line items.
Save by Bundling Services
Clients often save by combining demolition with other services, like renovation prep or landscape excavation. We offer package pricing for:
- Interior demo + post-reno cleanup
- Garage removal + driveway regrading
- Basement gut + waterproofing prep
Bundled quotes often result in 10–20% savings versus separate contractors.

Hi Demo Team,
I have the opportunity to purchase a condemned house in the west island of Montréal. Lot size around 6000, house size 2500 sqft, double garage.
There’s mold in the home as well, and I would like to have the foundation removed as well.
Could you give me a rough estimate for this scenario?
Best,
