Your renovation is done. The countertops are in. The tiles look great. The contractor shook your hand and left.
Then you look around.
Drywall dust on every surface. Sawdust inside your brand new kitchen drawers. Sticky residue on the windows from protective film. Paint specks on the baseboards. And a fine white powder settled on things three rooms away from where any work actually happened.
This is normal. And your contractor is not coming back to deal with it. You need a professional post-renovation cleaning service.
Why Contractors Don't Clean (and Shouldn't)
Contractors build things. That's their job. Most general contractors in Montreal will do a "broom clean" before handing over the space. That means sweeping the floors and hauling out the obvious debris (drywall scraps, lumber, packaging).
A broom clean is not a real clean. It's a courtesy. It gets the construction waste out of the way, but it doesn't address the stuff that actually prevents you from living in the space comfortably and safely.
The EPA notes that indoor pollutant levels can be significantly higher than outdoor air during and after renovation work, and recommends sealing air duct registers during construction and thorough cleanup afterward (EPA: Indoor Air Quality During Remodeling).
What a Broom Clean Leaves Behind
Fine drywall dust. This is the big one. Drywall dust is microscopic. It travels through your HVAC system and settles on surfaces in rooms where no renovation work happened. You can wipe a shelf, and 24 hours later it's dusty again. That's because the particles are still airborne, still settling. The EPA recommends HEPA filtration and proper ventilation strategy to manage these particles.
Adhesive residue. New windows, fixtures, and appliances ship with protective film, stickers, and labels. Contractors remove the big pieces but the sticky residue stays. It collects dust and looks terrible within a week.
Paint and caulk overspray. Small drops on baseboards, trim, light switches, and outlet covers. Invisible at first glance, obvious once you start actually using the space.
Sawdust and debris in hidden spots. Inside cabinets, behind appliances, inside closets, in vent covers. The stuff you don't see until you open a drawer and find a layer of grit.
What Professional Post-Renovation Cleaning Covers
A professional post-renovation cleaning service starts where the contractor stopped. The goal is to take the space from "construction complete" to "you can put your dishes away and make your bed."
At The Clean Panther, our post-renovation cleaning in Montreal covers:
- Every horizontal and vertical surface in the renovated area, wiped down multiple times to remove settled dust.
- All rooms where dust migrated (because it always migrates), not just the room where the work happened.
- Interior cabinets and drawers, cleaned so you can actually use them.
- Vent covers and baseboards, where dust accumulates the most.
- Light fixtures and outlet covers, including removal of adhesive residue and paint specks.
- Floors, vacuumed and mopped (sometimes multiple passes required for renovation dust).
We bring all equipment and supplies. You don't need to be home. We follow the dust wherever it went and clean the entire affected area.
When to Book Your Post-Renovation Clean
The right time to book is at least 24 hours after the contractors remove their tools and heavy debris. This gives airborne dust time to settle so we can clean it all in one visit. If tradespeople are still working in the space, we can't guarantee a dust-free result.
Most Montreal homeowners book us 1 to 2 weeks before they plan to move back in. With renovation activity expected to pick up across Canadian urban centers in 2026 (CMHC Housing Market Outlook), booking early is smart. We're typically 1 to 2 weeks out during peak season (spring through fall).
DIY Post-Renovation Cleaning: Why It Doesn't Work
You can try to clean it yourself. Most people do. Here's what happens:
You spend an entire weekend wiping surfaces. You go through a dozen rags. You think you're done. Then you walk through the next morning and everything has a thin layer of dust again, because fine particles were still settling from the air.
Post-renovation dust is different from normal household dust. It's finer, it's everywhere, and it doesn't respond well to a quick Swiffer pass. Professional-grade equipment (HEPA vacuums, microfiber systems, proper technique) handles it in hours. DIY takes days, and the result is usually worse. For context on what cleaning costs in Montreal, the investment is a fraction of the renovation itself.

FAQ: Post-Renovation Cleaning in Montreal
How long does post-renovation cleaning take?
A single-room renovation (bathroom or kitchen) typically takes 3 to 5 hours. A full-home renovation can take a full day with a 2-person team. The scope depends on how much dust migrated beyond the work area.
Can I stay in the home during post-renovation cleaning?
You can, but most clients prefer to leave a key and check in after. We'll text you when we're done and lock up behind us.
Do you remove heavy construction debris?
No. We're a cleaning company, not a junk removal service. We expect the contractor to remove drywall scraps, lumber, and boxes before we arrive. We handle the fine cleaning: dust, paint drops, stickers, residue.
Is post-renovation dust dangerous?
It can be. Fine particulate matter irritates the respiratory system, especially for people with asthma or allergies. The EPA confirms that indoor pollutant levels during renovation can far exceed outdoor levels. Professional cleaning removes these particles properly.
Do you serve areas outside Montreal island?
Yes. We cover the Greater Montreal Area including Laval, Longueuil, Brossard, the West Island, Rive-Nord, and Rive-Sud.
