Post-Construction & Renovation Cleaning in Montreal
A construction project doesn’t end when the last contractor leaves. Fine silica dust, VOC off-gassing, adhesive residue and grout haze remain — and require professional-grade expertise to address completely. Here’s everything you need to know.
Why professional cleaning matters here
Post-Construction Cleaning: What Montreal’s Contractors Don’t Tell You
Most new buildings are occupied without any professional dust remediation — because the visible debris has been swept away and the space “looks clean.” But CNESST Quebec recognizes crystalline silica dust from concrete, masonry and drywall as a serious respiratory hazard. This invisible threat settles into HVAC systems, under baseboards and inside cabinets.
The Montreal Cleaners has provided post-construction and renovation cleaning since 2010. Residential condos in Griffintown, commercial fit-outs in Laval, new-build homes in Boucherville — our teams handle the full spectrum with HEPA filtration and systematic 3-phase protocols on every job.
Pro tip: Schedule your clean at least 2 weeks before your expected completion date. Last-minute bookings in Montreal’s construction market mean 1–2 week delays. Book now →

Frequently asked questions
FAQ — Post-Construction Cleaning Montreal
How long after renovation can I move back into my Montreal home?
After professional post-construction cleaning with low-VOC products and proper ventilation, most residential spaces are safe to occupy within 24 hours — often immediately. Your cleaning team will advise based on specific products used and renovation scope.
Why hire professionals rather than doing it myself?
Construction dust contains crystalline silica — a particle that causes silicosis, an irreversible lung disease. Consumer vacuums recirculate these particles. Professional teams use HEPA systems (0.3-micron capture), N95 respirators and chemical-specific solvents. For anything larger than a single bathroom, professional service is strongly recommended.
Do you work with general contractors for multi-unit projects in Montreal?
Yes. We regularly partner with Montreal-area general contractors for multi-unit residential developments and commercial build-outs. We offer per-unit pricing, coordinated schedules and project documentation on request. Contact us early — post-construction capacity books out weeks in advance.
What is the cost of post-construction cleaning in Montreal ?
Pricing ranges from $180–$350 for a single renovated room up to $8,000+ for large commercial projects. A typical condo renovation runs $350–$700; a family home $600–$1,400. All quotes established after a free on-site assessment with no commitment required.
