After Builders Cleaning in Montreal — From Construction Site to Move-In Ready
Your project is finished — but what builders leave behind is more hazardous than it looks. Fine construction dust, chemical residues, adhesive and silica particles require HEPA-grade equipment and specialist expertise to remove safely and completely.
Why this isn’t just “a big clean”
What Construction Teams Leave Behind — And Why It Matters for Your Health
After any renovation or new construction, what remains is more complex than surface debris. Construction sites generate crystalline silica dust from concrete, drywall and masonry — particles fine enough to penetrate deep lung tissue. This is a genuine health hazard recognized by CNESST Quebec, not merely visible grime.
Beyond silica, post-construction environments contain VOC off-gassing from fresh paint and adhesives, grout haze on new tile, adhesive residue on floors, paint splatter on hardware, and protective films left by installers. All of these require specific chemical solvents and techniques.
The Montreal Cleaners has specialized in after builders cleaning since 2010. Our teams use HEPA-filtered vacuums (0.3-micron capture), N95 respirators, and a systematic 3-phase approach that ensures complete removal.

⚠️ Health Warning — Crystalline Silica Dust
Cutting, grinding or sanding concrete, masonry and drywall releases crystalline silica particles — some as small as 0.5 microns, invisible to the naked eye. According to CNESST Quebec, prolonged inhalation causes silicosis, an irreversible progressive lung disease. Never allow children, elderly individuals or immunocompromised people to occupy a newly renovated space before professional post-construction cleaning is complete.

Frequently asked questions
FAQ — After Builders Cleaning Montreal
How is after builders cleaning different from regular deep cleaning?
After builders cleaning addresses construction-specific residues: grout haze, adhesive residue, paint splatter, HEPA-level fine silica dust, protective film removal. These require different equipment, different chemical solvents and a systematic process. Regular deep cleaning maintains a lived-in space; after builders cleaning makes a construction site safe for habitation.
How soon after construction should I book cleaning in Montreal?
Immediately after contractor sign-off — ideally within 24–48 hours. Fine construction dust settles deeper into porous surfaces, HVAC systems and hidden spaces the longer it sits. Schedule your clean before your project ends, not after. Last-minute bookings in Montreal’s active construction market can mean a 1–2 week wait.
Are you available on weekends and evenings in Montreal?
Yes — 7 days per week, morning, afternoon and evening slots are available. For commercial projects, we recommend evening or weekend scheduling to minimize disruption. For residential projects, we coordinate around building access requirements for condominiums.
What’s the cost of after builders cleaning in Montreal ?
A 2-bedroom apartment typically runs $250–$450; a condo $400–$650; a family home $600–$1,200. Commercial projects are quoted on site. All pricing is established after a free on-site assessment — no commitment required.
