The remodel is done and the dust is everywhere: clean it yourself or call a crew?

The honest answer depends on the size of the project

You can clean up after a small project yourself, such as a new vanity, a painted room or a replaced light fixture, if you work top to bottom, use a vacuum with a HEPA filter and damp-wipe instead of dry dusting. After a larger remodel, a kitchen, several rooms or anything with drywall sanding or tile cutting, the fine dust settles into vents, cabinets, window tracks and every horizontal surface, and it usually takes more than one careful pass to remove. That is the job post-construction cleaning exists for, and it is worth hiring out when the project was big, the home is older or you need to move back in on a date.

I own Texas Kings Cleaning Services in Garland, and post-construction cleaning is one of the three kinds of work I do, along with residential and commercial cleaning. This guide explains why construction dust behaves differently, what you can handle yourself, and where the line is.

Why construction dust is not ordinary house dust

Household dust settles slowly and wipes away. Construction dust is finer and there is much more of it. Drywall sanding, cutting tile and stone, and sawing wood all create particles small enough to float in the air for a long time and to travel through the house on air currents and through the HVAC system. It keeps settling for days after the work stops, which is why a room cleaned on Monday can have a fresh film on Wednesday.

Some construction dust also deserves respect for health reasons. OSHA notes that cutting, sawing, grinding and drilling materials such as stone, concrete, brick and mortar creates respirable crystalline silica, which is linked to serious lung disease in workers who breathe it. In older homes there is a second concern: the EPA's Renovation, Repair and Painting program exists because work that disturbs painted surfaces in homes built before 1978 can release lead dust. If your home is that old and painted surfaces were sanded, scraped or demolished, the cleanup is not a job to improvise.

It also hides. After a project, I find dust on top of door frames and cabinets, inside drawers that were closed the whole time, in light fixtures and fan housings, on the blades of blinds, in the tracks of windows and sliding doors, behind outlet covers and along every baseboard. Clearing the visible surfaces makes the room look clean for a day. Reaching the hidden ones is what keeps it clean.

What the contractor's cleanup usually covers

Most contractors remove their debris, haul away scrap and sweep or vacuum the work area at the end of the job. Some contracts call that broom clean, which means the space is free of debris and swept, not ready to live in. Very few contractors wipe down the inside of every cabinet, clean window tracks, wash light fixtures or pull dust out of the return vents. Read your contract so you know which cleanup is included, and ask before the final payment if anything is unclear.

If you are still choosing a contractor or comparing bids, it is worth asking how they protect the rest of the house during the work and what the final cleanup includes. This guide from a remodeling contractor on comparing remodel bids that do not match covers the bigger picture of how to evaluate a contractor's scope.

What you can do yourself after a small project

For a single room or a contained job, a careful homeowner can get a good result. The key is method: work from the top down so you are not dropping dust onto surfaces you already cleaned, capture dust rather than push it around, and repeat the floor and surfaces a day or two later when the last of the airborne dust has settled.

Change the HVAC filter once the work is done, and again a few weeks later if the project was dusty. A filter that caught construction dust will keep releasing some of it if it stays in place.

• Vacuum with a HEPA-filter vacuum, starting high and working down
• Damp-wipe surfaces with microfiber instead of dry dusting
• Wipe inside cabinets, drawers and shelving in the work area
• Clean light fixtures, vents, sills and window tracks
• Vacuum and mop floors, then repeat after a day or two
• Replace the HVAC filter after the work ends

When it is time to bring in a cleaning crew

Hire out when the scale or the stakes go up. A whole kitchen or several rooms, drywall work across the house, a new build, or a move-in date that cannot slip are all good reasons. So is a household with someone who has asthma or allergies, or a baby who will be crawling on those floors, since the CDC notes that some cleaning products can trigger asthma and dust itself is an irritant.

If your home was built before 1978 and painted surfaces were disturbed, start with the EPA's guidance on lead-safe work and ask your contractor whether the work was done by a lead-safe certified firm, as the EPA recommends. That cleanup has specific methods, and it is the contractor's responsibility first. A post-construction clean comes after the work, and the work itself has to be done correctly.

Time is the other factor. A homeowner cleaning up after a kitchen remodel is often doing it in the evenings after work, around a household that is already worn out from weeks of construction. A crew that does this work regularly can usually finish in a fraction of the time with the right equipment, and in the Dallas area that often means the difference between moving back in this weekend or next month.

Tools and methods that make the difference

The biggest difference between a homeowner's cleanup and a professional one is usually the equipment and the order of work. A vacuum with a HEPA filter traps fine particles that an ordinary vacuum can blow back out through its exhaust. Microfiber cloths, slightly damp, pick dust up rather than spread it. Dry sweeping a floor covered in fine dust sends much of it back into the air, so vacuuming first and then mopping works far better.

Order matters as much as tools. Ceiling, fans and fixtures first; then walls, door frames and trim; then cabinets inside and out, counters and appliances; then windows, sills and tracks; then floors. Skip a step or do it out of order and you will be cleaning the same surface twice.

Plan for supplies, too. A dusty remodel goes through a surprising number of microfiber cloths and vacuum bags or filters, and cloths should be rinsed or swapped often so you are not wiping dust from one surface onto the next. Keep a separate set for glass and fixtures so they come out streak-free.

How a post-construction clean runs, pass by pass

On a larger project, I plan the clean in passes rather than one visit, because dust keeps settling. The first pass removes the bulk: leftover debris, heavy dust on floors and ledges, stickers and protective film, and dust inside cabinets and closets. The detail pass handles fixtures, vents, trim, glass, tracks, appliances and fine residue such as paint specks or grout haze on surfaces that can take it. A final touch-up, once the air has cleared, catches what settled after the detail pass and leaves the space ready to hand over or move into.

Not every project needs three visits; a remodeled bathroom may be done in one. The size of the project and how dusty the work was decide it, and I set that with the homeowner or contractor before we start.

• Rough pass: debris, heavy dust, film and stickers, inside storage
• Detail pass: fixtures, vents, trim, glass, tracks, appliances
• Residue: paint specks and haze on surfaces that can take it
• Final touch-up after the dust has settled

Mistakes that set the cleanup back

The most common is cleaning while the work is still going on. A trade coming back for one last fix can undo a full day of cleaning in an hour, so the final clean belongs after the punch list is finished. The second is dry dusting and sweeping, which lifts fine dust into the air to settle again. The third is forgetting the HVAC system: running it during the work without a fresh filter, or never changing the filter afterward.

Another is using harsh products on new finishes. New countertops, fixtures and flooring often come with care instructions, and the wrong cleaner can etch stone or dull a finish. Check the manufacturer's guidance before scrubbing. And never mix cleaning products to make them stronger; I explain why in common cleaning and disinfecting mistakes.

Scheduling the final clean with your contractor

The best time to book a post-construction clean is when the contractor gives you a completion date, not after. Tell me the size of the space, what work was done, whether there was drywall sanding or tile cutting, the age of the home, and the date you need to move back in or hand the space over. A few photos help. For larger jobs I may want to see the space before quoting, and I explain how size and condition drive the time in what affects the price of house cleaning.

I work with homeowners and with contractors who need a finished project cleaned before their client walks through, across Garland, Richardson, Mesquite, Rowlett and the Dallas area. Coordinating with the contractor's punch list is part of the job, so the clean happens once, at the right time.
