Renovations are exciting right up until the work stops and you see the dust. It is on every surface, inside the light fixtures, coating the window tracks, and it keeps reappearing for days. Post-construction cleaning is the job that turns a finished build site back into a livable home or a ready to open business. Here is what it actually involves.
Why it is not just a regular clean
Construction dust is a different animal. Drywall dust, sawdust, and concrete dust are extremely fine, they travel through the air, and they settle into places normal cleaning never touches. Wipe a counter and an hour later it has a fresh film. That is why a regular clean does not work here. Post-construction cleaning uses a methodical, top to bottom approach with the right tools, including HEPA filtration, so the dust is removed instead of just pushed around the room. If you want the broader difference between surface cleaning and detailed work, we cover it in deep cleaning vs regular cleaning.
The phases of post-construction cleaning
A proper job usually happens in stages rather than one pass.
1. Rough clean
This is the first sweep once the major work is done. It is about clearing leftover debris, larger material, and the bulk of the mess so the space is safe to move around in. Trades sometimes do this between phases.
2. Final detail clean
This is the heart of the service. Every surface gets addressed, from the ceiling fixtures down to the baseboards, with attention to the fine dust that has settled into corners, vents, and tracks. This is the pass that makes the space feel finished.
3. Touch up clean
After furniture is in or just before a handover, a final touch up handles any dust that resettled and any marks from moving things into place. It is the difference between clean and truly move in ready.
What is actually covered
The exact list depends on the project, but a thorough post-construction clean typically includes:
- Dust removal from all surfaces, including walls, ceilings, trim, and ledges.
- Light fixtures, ceiling fans, vents, and switch plates.
- Inside and outside of cabinets, drawers, and closets before they get used.
- Windows, frames, sills, and tracks, plus removal of stickers and adhesive residue.
- Paint splatter, grout haze, and construction residue on floors and fixtures.
- Kitchen and bathroom surfaces, sinks, and appliances cleaned and sanitized.
- Detailed floor care, vacuuming with proper filtration then washing.
For a finished home, this hands you a space you can actually settle into. See how it fits with our regular residential service on the house and condo cleaning page.
Homes and commercial build outs
Post-construction cleaning is not only for home renovations. New offices, retail fit outs, restaurants, and clinics all need the same treatment before they open, often on a tighter deadline. We handle both residential renovations and commercial projects across Montreal, so a contractor or property manager can hand off the final clean and focus on the opening. If your project is a workspace, our office and commercial cleaning team can also set up recurring service once you are up and running.
Why it is worth hiring out
Beyond the time it takes, there are real reasons to bring in a trained team. Construction dust is a respiratory irritant, so the right protective gear and filtration matter. Fresh finishes, new floors, and delicate fixtures can be scratched or damaged by the wrong cleaning method, and a team that does this regularly knows which products and techniques are safe on new materials. Doing it properly the first time protects the work you just paid for.
How it is priced
Post-construction cleaning is quoted per project rather than by a flat rate, because the scope varies so much. The size of the space, the amount of dust and debris, the number of windows, and whether it is a single room or a whole property all factor in. For a sense of how cleaning is priced in general, see our guide to house cleaning costs in Montreal. For a post-construction job specifically, the fastest path is a quick quote. Send a few photos or a short video of the space and we can price it without coming out in person.
