Finishing a construction or renovation project is exciting — until you see the mess left behind. Post-construction cleaning goes far beyond regular housekeeping. Construction dust, drywall particles, paint residue, and volatile organic compounds (VOCs) from new materials can linger in the air and on surfaces for weeks if not properly addressed.
At Mold Busters, we bring over 20 years of decontamination expertise to every post-construction cleanup, serving Ottawa, Montreal, and surrounding areas. What sets us apart? Our background in mold remediation and air quality testing. We don’t just make your space look clean — we make sure it’s actually safe to occupy.

Post-construction cleaning is a comprehensive, multi-phase process designed to transform a construction site into a move-in ready space. Our services cover every aspect:
- Debris and waste removal — clearing all construction materials and supplies
- Deep dust elimination — HEPA vacuuming of all surfaces including walls, ceilings, and vents
- Window and glass cleaning — removing paint splatter, adhesive residue, and construction film
- Floor cleaning and restoration — stripping coverings, cleaning grout, polishing hardwood
- Kitchen and bathroom sanitization — thorough disinfection of all fixtures and appliances
- HVAC and duct cleaning — removing construction dust from ventilation systems
- Surface disinfection — sanitizing all touchpoints including handles, switches, and railings
We also offer specialized disinfection services for healthcare and food preparation facilities.
How much does post-construction cleaning cost?
In Canada, post-construction cleaning typically ranges from $0.15 to $0.60 per square foot, with most residential projects falling between $500 and $2,000. Key factors that influence pricing:
- Size of the space — larger projects require more time and equipment
- Type of construction — new builds typically need more work than renovation cleanups
- Level of finish required — basic cleanup vs. deep decontamination with IAQ verification
- Presence of hazardous materials — older buildings may need specialized handling
- Location and timeline — rush jobs may cost more due to crew scheduling
After our extensive office renovation, the mess left behind was overwhelming. We hired Mold Busters for their post-renovation cleaning services, and it was the best decision we could have made. Their team didn’t miss a single detail, from sanitizing surfaces to removing every bit of construction debris. They transformed our chaotic space into a spotless, welcoming environment.
Why is professional post-construction cleaning important for your health?
This is where most cleaning companies fall short. Construction dust is not ordinary dust. It contains silica from drywall and concrete, wood particles from framing, chemical compounds from adhesives and paints, and fiberglass from insulation. Even in small quantities, these can cause respiratory irritation, allergic reactions, and more serious health effects.
The hidden mold risk after construction
In our 20 years of mold inspection work, we’ve seen countless cases where mold started during or immediately after construction:
- Building materials exposed to rain absorb moisture
- New drywall and concrete release moisture as they cure
- Sealed buildings trap VOCs and humidity inside
- HVAC systems circulate mold-promoting particles without proper filtration
That’s why we recommend indoor air quality testing as part of any post-construction cleaning project.
Construction dust can remain airborne and settle on surfaces for up to 6 months after a project ends. In our 20 years of inspections, we’ve found that post-construction spaces almost always have elevated particulate levels — often 3 to 5 times higher than safe indoor air quality thresholds. That’s why we always recommend air testing before occupancy.

How to choose the right post-construction cleaning company
Not all post-construction cleaning services are equal. Here’s what separates a surface-level cleanup from a truly safe, clean space:
- Certifications matter — look for IICRC certification, the industry standard for restoration professionals
- Equipment makes the difference — ask about HEPA filtration and air scrubbing capabilities
- Decontamination experience — a company experienced in remediation understands hazardous particulates at a deeper level
- IAQ verification — the best companies can test and verify air quality post-cleanup
- Insurance and guarantees — full insurance coverage and satisfaction guarantees
- Local knowledge — understanding of local building codes, climate, and construction practices
At Mold Busters, we check every one of these boxes. Our background in mold remediation means we approach post-construction cleaning with a health-first mindset. Contact us for a free assessment.

Post-construction cleaning in Canada typically costs between $0.15 and $0.60 per square foot, with most residential projects ranging from $500 to $2,000. The final price depends on the size of the space, type of construction, level of cleaning required, and whether specialized services like IAQ testing are included. We provide free virtual assessments and transparent quotes.
Yes. Construction dust contains silica particles from drywall and concrete, wood dust, chemical compounds from adhesives and paints, and fiberglass from insulation. These can cause respiratory irritation, trigger allergies and asthma, and lead to more serious health issues with prolonged exposure. Construction dust can remain airborne for months, which is why professional HEPA cleaning is important before moving in.
Absolutely. Building materials exposed to rain or humidity absorb moisture, new drywall and concrete release moisture as they cure, and sealed buildings trap humidity inside. HVAC systems without proper filtration circulate mold spores throughout the space. We recommend air quality testing as part of any post-construction cleanup to catch moisture and mold issues early.
Regular cleaning addresses everyday dirt. Post-construction cleaning deals with hazardous construction-specific contaminants — fine silica dust, VOCs, adhesive residues, paint overspray, and drywall particles that penetrate HVAC systems. It requires HEPA vacuums and air scrubbers that capture particles standard vacuums miss, plus attention to hidden areas like duct interiors and cabinet crevices.
