The walkthrough is Friday. The painter finished yesterday. Everything in the house is new, so it’s clean.
Right?
Not even a little. A new build might be the dirtiest place you’ll ever move into. Most of the mess just hasn’t shown itself yet.
The broom doesn’t count
Toward the end of a job, somebody usually pushes a broom through the rooms and fills a dumpster. That’s fine as far as it goes. The big stuff is gone. But nobody would call that ready to live in.
What the house needs is a slow, careful pass through every single room. I think of it as the handoff between the people who built the place and the people who’ll actually live there.
Where the dust is hiding
Sanding drywall, cutting tile, running trim. All of it throws off a powder so fine it hangs in the air for a while before settling on, well, everything.
Open a cabinet. Any one. It looks spotless because nobody has touched it yet, but run a finger along the shelf and see what you get.
The sliding door tracks will be full of grit. Window frames often still carry stickers and smudges from install day.
Now look up. Light fixtures, fan blades, vents, the tops of doors. Miss those and dust keeps sifting down onto everything you just cleaned, for weeks.
And the tile. New tile and stone usually have a cloudy haze after the grout goes in, and a damp mop won’t do much about it.
High to low
Clean high to low. Fixtures, fans, vents, and trim go first. Counters, cabinets, and sills come next. Floors are always last, because whatever you knock off a fan blade is coming down somewhere.
Also, careful with paint drips and leftover adhesive. Scraping hard at a fresh finish can leave a scratch that looks worse than the spot did.
When to book it
Not until every crew is gone for good. If the painter comes back for touch-ups, or the flooring guys need one more day, you’ll need a second round.
Get the scrap lumber, drywall pieces, and packaging hauled off first. That’s usually on the contractor, and most cleaning crews expect it done before they pull up.
When you’re calling around, listen to what they ask you. Teams that handle final construction cleaning in Martin County will want to know who else is still working in the house, and when those crews will wrap up. That’s a good sign. It means they’re planning around what the build actually left behind, not making it up at the door.
Ask for a Certificate of Insurance, too. Builders tend to want one on file. Owners should as well.
Let it breathe
Dust isn’t the only thing hanging in the air of a new house. New cabinets, flooring, and finishes can give off gases for a while after they go in.
The National Institute of Environmental Health Sciences lists fumes from new construction and home-finishing products among the major sources of formaldehyde in the air. What it recommends is pretty simple. More ventilation, especially after new sources come into the home.
So open the windows when the weather allows. Run the bath and kitchen fans. And change the A/C filter after the final clean, since it’s probably been breathing in construction dust for weeks.
One more thing nobody warns you about: the dust keeps settling for days, sometimes weeks, after the work stops. Check the cabinets again before the dishes go in. Plan a light touch-up a week or two after move-in, once the air has cleared.
Before you sign off on the final clean, do a quick test. Open three cabinets at random. Slide each glass door and look at the track. Check the tile in good light, and run your hand along a window sill. If those pass, the rest of the house almost certainly does too.
A new home looks done long before it’s actually clean. Give it the time.
