Dustless Hardwood Floor Refinishing in Atlanta, GA

Containment at the Drum, Vented Outside

TriArt runs vacuum containment on every sand, capturing dust at the drum and venting it to a sealed unit outside the house. This page is about the containment system specifically; the refinishing process, pricing and timelines are on the main refinishing page.

How the Containment System Works

What the equipment actually does

Conventional floor sanding puts a large volume of fine wood dust into the air of your house. It settles on every horizontal surface, gets into ductwork, and keeps turning up for weeks after the crew has gone.

Containment attacks it at the source. The sanding equipment is coupled directly to a vacuum line, so dust is pulled off the drum as it is generated rather than being allowed to become airborne. That line runs to a sealed collection unit positioned outside the house, which means the exhaust air leaves rather than being filtered and returned to the room.

Edgers and detail sanders are on the same system. That matters, because edge work happens at the room perimeter where furniture and fixtures are, and it is where uncontained dust does the most visible damage.

Return vents in the work area get sealed before anything runs, so dust that does escape has no route into the HVAC system and the rest of the house.

Nobody Removes All of It

An honest number, not a claim

No sanding process is dust-free, and anyone telling you otherwise is selling.

Not zero The honest version

What containment cannot capture

Containment captures the overwhelming majority of what a drum produces. What it cannot capture is what comes off hand-scraping in corners, what settles from the air during the seconds between generation and capture, and the fine residue that has to be tacked off the floor between coats. You will still want to wipe down surfaces in adjoining rooms afterwards.

What you should not expect is the experience people describe from uncontained jobs: dust on the top of the kitchen cabinets, grit in the bed linen two rooms away, and a film on the television that reappears for a month.

We would rather set that expectation before the job than have you discover it during. If a contractor promises you a genuinely dust-free sand, ask them what happens to the dust from the hand-scraping.

Who This Genuinely Matters For

Allergies, asthma, infants, renovations

For most households containment is a convenience. For some it is the reason the job can happen at all.

Medical rather than housekeeping

Households with asthma or respiratory conditions, where airborne particulate is a medical issue rather than a housekeeping one. Homes with infants or with an immunocompromised family member. Anyone who has been told to minimize dust exposure during recovery.

Floors inside a larger project

If cabinetry, millwork, or fresh paint is already in place, uncontained sanding puts fine dust onto surfaces that are difficult to clean without damaging them. We can advise on sequencing floors correctly within a renovation, and it is one of the things our general contracting work covers.

Staying in the house

Most families stay through a refinish, and containment is a big part of why that works. The work area is sealed off, but the rest of the house stays livable in a way it would not otherwise.

Pets in the house

Dust settles at floor level first, which is where dogs and cats spend their time. Containment reduces that considerably, though pets should be elsewhere during finishing regardless. Stairs are sealed off separately, and tread work is contained the same way.

What the Crew Does Differently on a Contained Job

Setup, containment, breakdown

Setup takes longer on a contained job, and that is where the difference is.

  1. Plastic goes up at every opening

    Not just the doorway. HVAC returns in the zone are sealed. The collection unit is sited outside and the vacuum line is run in through a window or door with the gap sealed around it.

  2. The line may run a long way

    On a two-story house that line can cover real distance, which is worth knowing when you are comparing a contained quote against an uncontained one.

  3. The unit is emptied outside

    During the sand the vacuum runs continuously, and the collection unit is emptied outside rather than in your garage.

  4. Vacuumed between grits, never swept

    Sweeping re-suspends exactly what the system just captured, which undoes the point of running it.

  5. Breakdown is where crews cut corners

    Plastic comes down last, after the final vacuum, and it comes down carefully. Pulling containment sheeting down quickly releases everything that settled on it.

Dust and Air Quality Questions from Atlanta Homeowners

Before you compare quotes

Is dustless refinishing really dust-free?

No, and we would rather say so. Containment captures the large majority of dust at the drum and vents it outside, but hand-scraping in corners and fine residue between coats still produce some. You will not get the experience of finding grit in bed linen two rooms away, which is what people mean when they ask this.

Does dustless sanding cost more?

Setup takes longer, which shows in the labor line. What it does not usually change is the finished floor. The question worth asking is whether the additional cost is worth avoiding a whole-house clean afterwards, and for a household with asthma or an infant it generally is.

Does the containment system affect the quality of the finish?

It improves it. Dust that stays airborne eventually lands, and if it lands on a wet coat it is sealed into the finish as a visible imperfection. Capturing it at the drum means less of it is in the air when the finish goes down.

Do you seal off the HVAC?

Yes. We seal return vents in the work zone before any equipment runs. This is the step that stops dust from traveling to parts of the house where nobody is working, and it is the one most often skipped.

Is this the same as the sandless refinishing I have seen advertised?

No, and the names are confusingly similar. Sandless refinishing chemically or mechanically abrades the existing finish and applies a new coat over it, without removing the old finish. It is closer to a recoat than to refinishing, and it will not remove damage that has reached the wood. Boards in that condition need replacing first. We do a full sand to bare wood, with the dust contained.

Can we stay in the house during a dustless sand in Atlanta?

Most families do. The work area is sealed and unusable while coats cure, but containment keeps the rest of the house livable in a way an uncontained job does not. Pets should be elsewhere during finishing, and that is about the finish rather than the dust.
