Usually both — and they are not the same clean. Builders commonly schedule a final clean before the certificate-of-occupancy inspection or your walkthrough; check your purchase agreement or ask the builder. That clean serves the builder’s handover. The detailed dust-down before your furniture arrives is usually yours to arrange, and it is a post-construction clean, not a move-in clean.
That’s the order this work has to happen in. If you’d rather hand the final dust to a crew, tell us the square footage and the handoff date and we’ll come back with a scope and a price in writing.
Two cleans, two clients
The builder’s final clean exists so the house can be handed over: inspected, walked through and closed. Our own pages for builders describe it. The general-contractor cleaning page lists “Final clean before your CO inspection: floors scrubbed by surface type, fixtures, doors, frames, and ledges detailed”, and the property-developer cleaning page lists “Sparkle cleans timed to buyer walkthroughs, TCO inspections, and closing-day handoffs”. It is a real clean, to the builder’s standard.
A certificate of occupancy, or CO, is the building department’s sign-off; a TCO is the temporary version. Miami-Dade County’s permitting site, for one, says a CO “validates that a building (or renovation project) has been completed in compliance with applicable code(s).” Nothing in that is about the inside of a cabinet.
The same general-contractor page is candid about when that clean happens: “Your CO inspection date does not move, but every trade ahead of you slips — the final clean gets squeezed into whatever window is left.” A clean squeezed in before an inspector arrives was never planned around your move-in.
So before closing, ask the builder three things:
- Is a final clean included, and what does it cover? Only your purchase agreement, or the builder in writing, can answer that.
- When does it happen? Before your walkthrough, or after the punch list is finished?
- Will any trade work inside after it? Drywall patches, touch-up paint, a rehung door, a late appliance install.
Why a cleaned new house still has dust on move-in day
Dust in a house the builder cleaned last week does not necessarily mean anyone skipped anything. Construction dust simply outlasts the clean, and our general-contractor page names where it goes: it keeps settling into “window tracks, cabinet interiors, and mechanical closets long after the sweep-out — turnover-grade detail is its own trade.” Three things put it there.
The first is the settle. Our post-construction cleaning in Miami page puts it plainly: “After drywall-heavy work, airborne dust keeps settling for a day or two, so some clients add a lighter follow-up pass once it lands.” In a new build, that settle applies to the whole house, not one room.
The second is the punch list. Many of its fixes are small construction jobs inside a house that was already cleaned: a drywall patch sanded, a baseboard trimmed, a door planed so it closes. Each of those puts fresh dust on finished surfaces.
The third is the air. Once the air conditioning or heat runs, it moves air through every room, and whatever is still floating, or resting on a vent cover, travels with it. None of it means a bad build; it is why the clean that matters for move-in comes last.
At the walkthrough, sort what you find into two lists
Use the walkthrough to look where a quick clean misses: slide a window or patio door open and check the track, look along the top of a door frame, open a few cabinets and drawers, and get close to the window sills and vent covers. Then put each thing you find on one of two lists.
The builder’s list is anything damaged, defective or unfinished: a scratched floor, a chipped countertop edge, paint that needs touching up, a door that sticks, a missing switch plate. Those belong on the punch list, in writing, because they are the builder’s to fix. No cleaning visit repairs a scratch or rehangs a door.
The cleaning list is everything else: powder in tracks and on ledges, smudges on fixtures, sticker residue, protective film on glass. That list is what the clean before your furniture is for; name any stickers and film in your quote request, so the reviewed quote can confirm them. If powder still lines the tracks after the builder’s final clean, the detail work is still ahead of you.
Move-in clean or post-construction clean?
A move-in clean is generally built for a home someone already lived in: their grime in the cabinets, the appliances and the bathrooms. A new build has never been lived in. Its problem is powder, so our post-construction page lists move-in among the times to book a post-construction clean: “A newly built or remodeled home needs a full dust-down before the furniture and boxes arrive.”
Comparing it with a deep clean, the same page says “Same detailed checklist, different enemy”, and names the enemy: “fine renovation dust that coats every surface and hides in vents, tracks, hinges, and cabinet interiors.” The published checklist, item by item, is in what post-construction cleaning is and what it includes; the figures are in how much post-construction cleaning costs.
When to book it
Work backward from move-in day. The clean goes after you have a way in, after the last punch-list trade leaves and after the dust has had a day to settle, and before the moving truck. Our post-construction page’s readiness list: “Construction finished and trades off site, bulk debris removed, working power and water, and safe access — a key, lockbox code, or an on-site contact.” And the rule behind it: “We clean finished spaces, not active job sites.”
On timing, the page says: “Booking typically runs on a 24–48 hour lead time, so a good rhythm is to request your time as the punch list wraps up — the clean lands right before your walkthrough, photos, or move-in.” For a buyer, that event is the move-in. Furniture counts too: “whether the space is empty or already furnished” is one of the published price factors.
Before closing? Only if the builder lets a crew in: until then, access is the builder’s call, and we cannot promise a date in a house we have no key, code or contact for. Otherwise, leave a gap between getting the keys and the moving truck.
What stays with the builder, and what we won’t promise
Some work stays with the builder whoever books the clean. Bulk material is the clearest case, and the post-construction page says so: “Bulk debris — lumber offcuts, drywall sheets, packaging, old fixtures — is the contractor's haul-away.” Our property-developer page draws the same line from the builder’s side: “Rough cleans during active construction and debris hauling stay with the GC’s site crew”.
Air vents are on the published checklist; the ductwork behind them is another trade with its own equipment. Sealing new grout and exterior glass above the ground floor sit outside the visit too, and the full list, with whose job each item is, lives in what post-construction cleaning does not include.
We won’t promise access before closing, which is the builder’s call, or any inspection outcome: a clean is not an inspection. We make no air-quality or health claims either; to us, construction dust is powder and film on surfaces, and surfaces are what we show you. On eligible completed visits, your CleanCheck Report includes checklist status and customer-safe photos. This is general information, not legal advice; for what your contract covers, read your purchase agreement and take any questions to your builder or an attorney.
If the new home is in South Florida
In Miami-Dade, where we operate, the post-construction page gets specific: “New-build and first-owner homes in Doral and Homestead need a full top-to-bottom dust-down before the furniture arrives.” In a brand-new condo tower, the page’s price factors include “elevator reservations and parking in condo towers”, so ask the management office about its vendor rules before you pick a day. And if closing lands between June 1 and November 30, the Atlantic hurricane season as NOAA’s National Hurricane Center defines it, leave a buffer day between the clean and any date that cannot move.
Quick answers
Does the builder clean before closing?
Commonly, yes: builders tend to schedule a final clean before the certificate-of-occupancy inspection or the buyer walkthrough. To find out whether yours does, and what it covers, check your purchase agreement or ask the builder. Either way, that clean is timed to the builder’s handover, not to the day your furniture arrives.
Is the builder’s final clean enough to move in?
Sometimes. If no trade has worked inside since and the window tracks, door-frame tops, cabinet interiors and vent covers come up clean, it may be. If punch-list repairs came after it, book a post-construction clean between the last repair and the moving truck.
Can you clean before I close?
Only if the builder lets a crew in. We need the trades off site, working power and water, and safe access: a key, a lockbox code or an on-site contact. If that is not possible before closing, plan the clean between getting the keys and the moving truck.
What about stickers and protective film on new windows and fixtures?
Name them in your quote request. Our general-contractor page lists “stickers, labels, and protective film removed” as part of builder-side glass detail; for a home, the reviewed quote confirms what is in scope before anything is scheduled.
