You’ve waited weeks — maybe months — for the renovation to finish. The new kitchen looks incredible. The bathroom tile is exactly what you picked. The contractor says the job is done.
Then you look around and realize: there’s a fine layer of dust on every surface, grit in the window tracks, sticker residue on the glass, and paint splatter on the floor edges. The construction may be done, but the space isn’t livable yet.
That’s what post-construction cleaning is for. It’s not regular cleaning — it’s a specialized process designed to remove the specific debris that renovation and building work leave behind.
Why post-construction cleaning requires special attention
Construction dust isn’t like household dust. It’s finer, heavier, and sticks to everything. Depending on the project, it can include drywall particles (calcium sulfate), which settle into a chalky film on every surface. Wood dust from cutting, sanding, and framing. Concrete and morite dust from masonry work. Silica particles from tile cutting and grout work. Paint overspray and adhesive residue.
This kind of dust doesn’t just wipe away. It embeds in carpet fibers, settles inside air vents, coats the inside of cabinets, and films over windows. A standard cleaning approach — even a thorough one — won’t fully remove it.
The other issue is HVAC contamination. If the heating and cooling system ran during construction (which it often does), fine particles have been pulled into the ductwork and distributed throughout the house. Even rooms that weren’t part of the renovation can have a film of dust.
What a professional post-construction clean includes
The process typically happens in phases. How many depends on the scale of the project.
Phase 1: Rough clean (if needed)
This happens right after framing, drywall, and major installations are complete but before finish work begins. The goal is to remove large debris — scrap material, packaging, dust piles — so the finish crew can work in a clean environment.
Not every project needs this step. It’s most common in new builds and major renovations.
Phase 2: Detail clean
This is the core of the process and where our team at Asubra focuses most of the work. It happens after all finish work is complete — painting, tile, fixtures, cabinetry — and after the contractor has removed their tools and equipment.
The detail clean covers:
All surfaces wiped down from ceiling to floor. Inside new cabinets, drawers, and closets (they collect sawdust and packaging debris). Window glass cleaned and sticker/label residue removed. Window tracks and sills cleared of grit and dust. Light fixtures, outlet covers, and switch plates wiped. Baseboards, trim, and door frames cleaned by hand. Tile and grout cleaned of haze from installation. Countertops scrubbed and polished. Appliance interiors and exteriors cleaned. Full floor cleaning — vacuuming, mopping, and edge detail.
Phase 3: Touch-up clean
A follow-up visit to catch anything missed after the dust has had a day or two to settle. Renovation dust has a way of reappearing — it drifts out of vents, falls from light fixtures, and migrates from areas that weren’t fully sealed during the project.
For larger renovations, we recommend scheduling this 3-5 days after the detail clean. For more details, see cleaning a new build before move-in.
Common problems we see after renovations
After years of doing post-construction work on the South Shore, a few issues come up again and again:
Drywall dust in the HVAC system. If the vents weren’t sealed during construction, the system has been circulating fine dust throughout the house. We clean accessible vent covers and registers, but we also recommend having a duct cleaning company handle the interior of the ductwork if the renovation was extensive.
Grout haze on new tile. When grout is applied and wiped, a thin residue stays on the tile surface. It looks cloudy or dull. The fix depends on the grout type — cement-based grout haze can usually be removed with a mild acid solution, while epoxy grout haze requires a specific remover. If your tile looks hazy after installation, mention it when you book so we can plan accordingly.
Paint splatter on floors and trim. Small drips and overspray are almost unavoidable during a renovation. Fresh latex paint comes off relatively easily with the right technique. Dried or oil-based paint requires more care — especially on hardwood floors where aggressive scraping can damage the finish.
Sticker and adhesive residue on windows and fixtures. New windows, appliances, and fixtures come with manufacturer stickers and protective film. The adhesive left behind needs a specific approach depending on the surface. On glass, a razor scraper works well. On stainless steel or coated surfaces, a gentler solvent is safer.
How long does it take?
Timing depends on the scope of the renovation, the size of the home, and how much dust was generated.
A kitchen and bathroom remodel typically requires 4-6 hours for the detail clean with a crew of two. A full home renovation or new build can take a full day or more. Additions and multi-room projects fall somewhere in between.
If the contractor did a good job cleaning up after themselves, the job goes faster. If they left debris, packaging, and heavy dust behind, it takes longer.
We’ll give you a clear estimate after you describe the project and the current condition. Photos help a lot.
When to schedule the cleaning
The ideal timeline: For more details, see when to schedule relative to your project.
- Contractor finishes all work and removes tools/equipment
- You do a final walkthrough with the contractor (before the cleaning)
- Cleaning team comes in
- Touch-up visit 3-5 days later (for larger projects)
- You move furniture back in and enjoy the space
Don’t move furniture or belongings back in before the cleaning. Like move-out cleaning, an empty space allows the team to reach every surface and corner.
