Commercial demolition in Montréal covers offices, retail, restaurants, and warehouses — selective strip-outs, tenant fit-out clear-downs, and full interior teardowns. Cost depends on size, access, materials, asbestos, and disposal, so every job is quoted after a site visit. DemoPrep is RBQ-licensed and works around your building’s hours.
What Commercial Demolition Covers
Commercial demolition is a different job from a home teardown — tighter schedules, occupied neighbours, building-management rules, and far more debris. DemoPrep handles the full range across Greater Montréal:
- Tenant fit-out strip-outs: clearing a leased space back to base-building for the next tenant — flooring, partitions, ceilings, millwork, MEP rough-out.
- Office and retail interiors: selective demolition that keeps the structure and shell intact while removing everything inside.
- Restaurants and commercial kitchens: grease-laden equipment, hoods, walk-ins, and tiled wet areas removed and disposed of correctly.
- Warehouses and industrial units: larger-volume teardowns with the right equipment and waste handling.
What Commercial Demolition Costs in Montréal
There is no honest flat rate for commercial work — a single-suite office strip-out and a full restaurant gut are not the same job. Price is driven by the square footage, building access (loading dock, freight elevator, downtown vs suburban), the materials being removed, whether asbestos or other hazardous materials are present, and disposal volume. Rather than quote a number a competitor could undercut, we price each project after a site visit and give you a clear written scope.

Why the Right Commercial Crew Matters
- Schedule: commercial landlords and tenants work to hard deadlines — we plan around business hours and can work evenings or weekends to avoid disrupting neighbouring units.
- Compliance: Québec commercial work means RBQ licensing, CNESST safety, and proper construction-waste (CRD) disposal — not a cash crew with a trailer.
- Hazardous materials: older commercial buildings frequently contain asbestos in flooring, drywall compound, and mechanical insulation; it must be tested and contained before demolition.
Our Commercial Demolition Process
Step 1 — Site visit and scope
We walk the space, confirm what stays and what goes, flag any suspected asbestos or hazardous materials, and give you a written scope and quote.
Step 2 — Containment and safety
Where hazardous materials are confirmed, the area is contained and abated before demolition. Our crews use MSA Advantage 3200 full-face respirators with P100 Flexi-Filters, dust control, and HEPA filtration at 99.97% on hazardous scopes.
Step 3 — Demolition and clean haul-out
Selective demolition is done in sequence to protect base-building systems, with debris sorted for recycling and the space left broom-clean and ready for the next trade.

Most commercial demolition in Montréal requires a permit; rules differ by borough and by independent city. We confirm what’s needed and pull it as part of the job — see the City of Montréal’s demolition permit process.

Frequently Asked Questions
Do I need a permit for commercial demolition in Montréal?
Usually yes. Most commercial demolition — interior or full — requires a municipal permit, and the requirements differ between Montréal boroughs and independent cities. We confirm what’s needed and handle it as part of the project.
Can you work after hours so we don’t disrupt our business?
Yes. Commercial schedules are tight and neighbouring units stay open, so we regularly work evenings and weekends and coordinate with building management for elevator and dock access.
How do you handle asbestos in an older commercial building?
Suspect materials are tested first. If asbestos is confirmed, the area is contained and removed under proper controls before any demolition begins — flooring, drywall compound, and mechanical insulation are common sources in commercial buildings.
How is commercial demolition priced?
By the actual scope — size, access, materials, hazardous materials, and disposal. We quote each job after a site visit and give you a written scope rather than a guessed flat rate.
