TL;DR: Most home renovation contractors in Montréal split your project across three crews — and the handoffs between demolition, abatement, and construction are where renovations lose weeks. DemoPrep Montréal (RBQ #5826-5448-01) runs demolition, hazard management, and complete residential renovations under one licence, one schedule, and one point of accountability.
Where multi-contractor renovations lose their weeks
A typical Montréal renovation splits the work three ways: one crew for demolition, a specialist if asbestos turns up, and a builder for the reconstruction. Each split is a handoff — and each handoff means a new mobilization, a re-quote when site conditions don’t match the plan, and a gap in the calendar while the next contractor fits you into their schedule. When something goes wrong between phases, accountability splits with it.
Homes built before 1990 make this worse. Plaster, vinyl flooring, and pipe insulation from that era must be checked for asbestos before disturbance under Québec rules, and a positive test in a multi-contractor setup stops everything while a fourth party gets sourced and scheduled.
What sets us apart from other home renovation contractors
- Demolition: selective strip-outs through full guts, dust-controlled with 99.97% HEPA filtration and sealed containment.
- Hazard management in-house: testing from $350, and when abatement is in scope, our crews work in MSA Advantage 3200 full-face respirators with P100 Flexi-Filters — no waiting on a third-party specialist’s calendar.
- The rebuild: complete residential renovations — kitchens, bathrooms, basements, open-concept conversions — design to finish, under the same RBQ licence that opened the walls.
On larger builds we also work directly alongside general contractors as partners — same site, shared schedule, structural findings documented and handed over in person, not discovered later.
What the numbers look like
| Scope | Starting Price |
|---|---|
| Basement finishing — full build-out | From $15,000 |
| Basement finishing — large or high-spec build | From $40,000 |
| Structural wall removal (open-concept conversions) | From $1,200 |
| Ceramic tile installation | From $10/sq ft |
| Demolition phase — selective strip-out to full gut | From $1,500 |
Final quotes vary by scope, finishes, and site access. Full residential renovations typically run 4–10 weeks depending on scope.
Where this matters most in Greater Montréal
- Westmount: heritage homes and high-end gut renovations — original materials and structural quirks reward a team that carries the project from discovery through finish without re-quoting at each phase.
- Laval: suburban and semi-detached stock — shared structural elements in semis demand continuity between the crew that opens the wall and the crew that rebuilds it.
- Brossard: modern South Shore homes — open-concept conversions hinge on load paths, and one team owning both the removal and the rebuild keeps the engineering tight.

Frequently Asked Questions
Do you handle the full renovation or just the demolition?
Both. We run complete residential renovations — kitchens, bathrooms, basements, open-concept layouts — from strip-out to finish. Demolition-only scopes are equally welcome.
Do you work with general contractors?
Yes, directly and as partners. On larger builds we integrate with the GC’s schedule, share structural documentation as walls open, and coordinate trades sequencing on site.
What happens if asbestos is found mid-project?
Nothing stalls. Testing and abatement are in-house — the zone is sealed, the material is handled under containment, and the build schedule absorbs it instead of waiting on an outside specialist.
How do I verify a renovation contractor’s licence in Québec?
Search the licence number in the RBQ’s Registre des détenteurs de licence — it shows active status and authorized work categories. Ours is RBQ #5826-5448-01, on every quote we issue.
