We clean from the ceiling down

Construction dust settles on every surface

Sanding drywall or cutting tile makes a dust finer than flour. It hangs in the air for hours after the saw stops and rides through open doorways before it settles on every flat surface in the house. That includes rooms nobody worked in. A contractor's broom and shop vacuum get the chunks off the floor. They do not get the white film on top of the door frames or the shelf inside a closed cabinet.

So a post construction clean is detail work in every room. We start with the ceiling fans and work down to the tops of door frames and window trim. Walls get washed where the dust settled on them, and cabinets get wiped inside and out. Door knobs get wiped by hand. Interior windows get cleaned once the sills below them are clear. Hard floors get mopped and rugs get vacuumed last, after everything above them has dropped its dust.

When the job is finished, you can run a finger along the top of a door and come away clean. The cabinet shelves are ready for dishes. The floor does not feel gritty under bare feet, and the windows do not show a haze when the afternoon sun hits them. If you can still write your name in the dust on a windowsill, the job was not finished. The next time the air conditioning kicks on, that dust spreads again.

• Ceiling fans dusted before anything below them
• Walls washed where the sanding dust settled
• Cabinets wiped inside and out
• Interior windows and door knobs cleaned
• Hard floors mopped and rugs vacuumed last

Dry dusting comes before any water

The most common mistake after a remodel is reaching for a wet rag first. Drywall dust is ground gypsum, and joint compound dust behaves the same way. Add water and it turns into a thin paste that smears across paint and dries as a pale streak. On dark cabinets and black appliance fronts, that streak shows from across the kitchen. So every surface gets dry dusted or vacuumed before a damp cloth touches it.

The order matters just as much as the method. Dust falls, so we clean the ceiling fans before the counters and the counters before the floor. If the floor gets mopped first, the fan blades drop a fresh layer on it the moment someone turns them on. Cabinets work the same way. Wiping the fronts before the tops means dust from the top edge runs down the doors you just cleaned.

Floors come last and get the most care. Tile grout and the seams in vinyl plank hold grit, and grit dragged under a mop scratches the finish. We vacuum hard floors first to lift that grit out, then mop with a cloth that is damp rather than soaked. Rugs get vacuumed slowly with overlapping passes, because fine dust works down into the pile where one quick pass cannot reach it.

Older Norfolk homes make heavier dust

A lot of the older housing in Norfolk and Portsmouth still has plaster walls over wood lath. Opening one up for new wiring or plumbing makes a different mess than drywall does. Plaster dust is gritty and heavy, it carries bits of old lath and hair binder, and it packs into the gaps between old hardwood boards. That gap dust has to be vacuumed out before anyone mops, or it keeps working back up.

The brick ranches and Cape Cods built after the war are mostly drywall inside, often under several layers of paint. Sanding that for a patch or a new doorway throws the flour fine dust that floats. Many of these houses also sit over crawl spaces, since the water table around Hampton Roads is too high for most basements. Their heat and air registers are often in the floor, so dust that settles in them blows back out later.

Newer houses in Chesapeake and Virginia Beach are mostly drywall inside, with a lot of hard flooring and open floor plans. After a kitchen or bath remodel there, the dust is less about grit and more about how far it travels. Sanding in the kitchen reaches the living room and settles on the stairs. So the clean covers the whole open area the dust could reach, and the stairs get the same attention as the room with the new cabinets.

Humid summers make fine dust stick

Summers around Norfolk run hot and damp, and that changes how dust behaves. In dry air, fine dust sits loose on a surface and comes off with a dry cloth. In humid air it takes on moisture and clings. On a cool surface like a window or a steel appliance it can cake into a film. That is why the dry pass has to be slow and careful on a muggy day, with fresh cloths swapped in often.

Spring brings its own problem. Pine pollen coats everything in Hampton Roads for a few weeks, and a remodel means doors propped open all day for tools and materials. The yellow dust comes in and mixes with the white dust from inside. It collects on the sills and on the floor inside the entry door. Left there, it gets tracked through the house on shoes and ends up in the rugs.

Then there is the air system. While the sanding goes on, the return pulls dust into the filter until the filter stops catching it. If nobody changes that filter after the work ends, the system blows construction dust back into the clean rooms for weeks. Swap in a fresh filter right before the clean and again a couple of weeks later. That one step keeps the house clean long after the last contractor leaves.

Book the clean after the painters leave

Timing decides how long a clean lasts. Fine dust keeps settling out of the air for a while after the last cut. Every trade that comes back for a touch up brings more. The best time to book is after the final coat of paint is dry and the last contractor has packed up. If a punch list is still open, the clean can wait until it is done, so you only pay for it once.

Before we come, ask the contractor to haul away the scrap, offcuts, paint cans and plastic sheeting. That leaves every surface open to reach instead of hidden behind piles. Pull any painter's tape off the windows if it is still there, since old tape leaves a sticky film on the glass. If furniture got pushed into one room during the work, tell us when you book. We move furniture as part of the job when it is needed.

When the clean is finished, the house should look ready to live in again. Pamela Abad wrote on Google: "After cleaning each room they take a photo and send them all to you." That helps if you are staying somewhere else until the work wraps up. You can check each room from wherever you are. If a corner got missed, you see it in the photo. Then you can tell us right away.
