How Much Dust Will This Actually Make?

This is the question people ask last, usually as I'm walking to the van, and it should be asked first. Especially if there's a baby in the house, someone with asthma, or an open floor plan where one room is really four.

So here's the honest version.

Which jobs make dust and which don't

It varies more than people expect.

Almost none: TV mounting, furniture assembly, shelf installation, caulking, most hardware and door work. Some drilling dust that a vacuum handles on the spot.

A moderate amount: patching one or two holes. The sanding stage is localized and contained to the immediate area.

A real amount: texture matching across a larger area, a ceiling repair, or several patches in one room. Ceilings are the worst of it, because everything sanded overhead comes straight down and spreads on the way.

Drywall dust is very fine and stays airborne longer than sawdust. Left uncontained in an open floor plan, it will find the kitchen.

What I do about it

Plastic sheeting over doorways and openings to close the work area off from the rest of the house. Drop cloths on the floor, not just under the patch — dust settles across a wider radius than the work itself.

Furniture that can't move gets covered. Vents in the work area get closed off, because a running HVAC system is an efficient way to distribute dust through the whole house.

Sanding with a vacuum attachment wherever the work allows it, which catches a large share at the source. And cleanup at the end: vacuum, then wipe surfaces, because fine dust settles for a while after the sanding stops.

What I'd ask you to do

Small things that make a real difference.

Move anything soft and irreplaceable out of the room — upholstered furniture, rugs, bedding, curtains. Fabric holds fine dust in a way hard surfaces don't.

Clear the wall area a few feet in each direction, and take pictures and mirrors off nearby walls rather than leaving them to be covered.

If you have an air purifier, run it in the room afterward. And if anyone in the house has asthma or significant allergies, tell me — it changes how I set up, and it may be worth planning the work for a day when they're out.

The honest limitation

Containment is very good. It isn't perfect. Sheeting over a doorway is a barrier, not a seal, and drywall dust is fine enough that a small amount will get past it.

After a bigger job you may find a light film on a surface in the next room, and it wipes off easily. What you shouldn't find is dust through the rest of the house, or grit underfoot in a room I worked in.

If you've had drywall work done before and it was a disaster afterward, that's usually because nothing was closed off and the HVAC ran through the whole job. Both are avoidable.

Timing worth considering

Dust settles for a few hours after sanding stops. If it's a bigger job and you're sensitive to it, having the work done earlier in the day means the air is clear by evening — and it's easier to open a window in September than in January.

Common Questions

Does drywall repair make a lot of dust?

It depends on the job. Mounting, assembly and caulking make almost none. Patching produces a localized amount at the sanding stage. Ceiling work and larger texture matching produce the most, because everything sanded overhead spreads on the way down.

How is drywall dust contained?

Sheeting across doorways to close off the work area, drop cloths beyond the immediate work zone, covering furniture that can't be moved, closing vents so the HVAC doesn't distribute dust, and sanding with vacuum attachment where the work allows.

What should I move before drywall work starts?

Anything soft and irreplaceable — upholstery, rugs, bedding, curtains — since fabric holds fine dust. Also clear the wall area and take down nearby pictures and mirrors.
