Construction Dust Control and Cleaning Tips for Pros
Home renovations can get messy fast. Prevent big messes from accumulating in the first place, clean as you go, or clean up efficiently with these tips for professionals.
Lay Down a Protective Path
It's impossible to demo a wall or bust up a floor without making a mess, but that doesn't mean you need to track that mess all over the rest of the house. The next time you have to tear out some carpet, cut several long strips, and use them as pathways to protect the flooring in other areas of the house. Make sure to flip the carpet upside down so the abrasive backing won't scratch the finish on wood floors. Canvas drop cloths are still the best method for protecting stair treads.
Drive Dust Outside With a Fan
A fan blowing out the window
helps to keep dust levels down,
and it creates a slight vacuum in the
work area. That way, any gaps in your
dust barrier will let air flow into the
work zone, but dust-laden air can't
sneak into surrounding rooms. This
works so well, in fact, that you may
not even need a dust barrier for light-dust
projects. Just be sure to close
large gaps around the fan with
cardboard or plastic so wind gusts
don't blow the dust right back inside.
For good airflow, you may have to
crack open a door or window on the
opposite side of the room.
Protect Finished Flooring with Hardboard
Rosin paper, cardboard and dropcloths are all legit ways to protect a floor—that is, until you knock your trim gun off the top of a 6-ft. ladder. If you really want to ensure that a floor stays dent- and scratch-free, cover it with 1/8-in. hardboard. It's pretty cheap, and as the name suggests, it's pretty hard. Cut the sheets with a circular saw or jigsaw, and to prevent scratches, make sure both the floor and the hardboard are perfectly clean before you lay the hardboard down. Tape the seams with masking tape to keep the dirt and debris from slipping through the cracks. When the job is done, pull up the sheets and save them for the next job.
Cover up Air Ducts
Construction dust sucked into return air ducts can plug
your furnace filter. Even worse, small particles can pass
through the filter and coat every room in the house with a
blanket of fine dust when the blower turns on. Air supply ducts
can be a problem too—dust that settles inside will come blasting
out when your heating/cooling system starts up. You can
close the damper on a supply register, but it won't seal out dust
as effectively as plastic and tape. Note: Turn off the heating/
cooling system while the ducts are covered. Operating the system
with restricted airflow can damage it.
Make a Plastic Passage
Hanging sheets of plastic from the ceiling is a good way to isolate a room that's being remodeled. But instead of hanging one continuous sheet to keep the dust in, hang two and overlap them 4 ft. or so. That way you'll have a handy door to walk through, which beats having to duck under the plastic every time you come and go. Lay a scrap piece of lumber on the bottom of the plastic to keep it in place.
Vacuum While You Cut
If you're cutting or drilling drywall, you'll have to drag out the vacuum sooner or later anyway. So do it now and suck up the dust before it spreads. If your plans include lots of drywall dust, consider buying a HEPA filter, which will catch even the smallest particles. Standard paper filters trap only the larger particles while your vacuum blasts the rest throughout the house.
Remodeling contractors, listen up! Buy a set of four Zip Poles for all those dusty jobs that you need to isolate from the rest of the house. You can quickly set up a temporary wall or booth with the telescoping poles and hang some poly. The poles clamp the plastic against the ceiling by pushing against the floor. For most jobs you'll need four of the 10-ft. steel poles. Longer aluminum poles are also available. You can buy Zip Poles on Amazon or at tool suppliers.

Wear a Respirator, Not a Dust Mask
Dust masks and respirators may look the same, but respirators are designed to block 95 percent of small particles (0.3 micron). To find a true respirator, look for “N95” on the label. In order for a respirator to work, it needs to fit properly. There are respirators available in small, medium and large—wear one that fits. And for you blokes with bushy beards, respirators are better than nothing, but they won’t provide the protection you need. If you work around dust a lot, you should ditch the whiskers.
Save Trips to the Vac
Using a vacuum as a dust collection system makes a lot of sense, but walking back and forth to turn it on or off can get a bit tedious, and listening to it run all day is not an option. Do yourself a favor and pick up an i-Socket Autoswitch. Plug the Autoswitch into the wall, and then plug the tool and the vac into the Autoswitch. Every time you fire up the tool, the Autoswitch will trigger the vac. Once you’ve made your cut, the vac continues to run for seven seconds so it can finish sucking up the dust.
Make Your Wet/Dry Vacuum Filter Last Forever
Fine drywall and masonry dust will plug a vac filter almost immediately. The Dust Deputy from Oneida separates large and small particles into a 5-gallon bucket before they can reach your vac, so you don’t have to waste time cleaning the filter every three minutes.
This model comes with two buckets, all the hoses you need and casters for the bucket. The bucket can be permanently fastened to the vac, but the pros we talked to prefer to strap it on with a bungee so it can be easily separated for dumping. A 5-gallon bucket is a lot easier to carry outside to dump than a cumbersome vac canister.
Dust-Sucking Rotary Tool
Nothing works better at cutting holes in drywall than a rotary tool. It’s also true that nothing fills a room with dust faster. Thankfully, RotoZip has figured out how to control that dust. Its new RotoSaw with Dust Vault has an integrated dust collection system that reduces airborne dust by up to 90 percent. It also works on wood, cement board and tile, among other materials.
Exhaust the Vac Outside
Want a sure way to kick up a bunch of dust on a remodel site? Switch on a vacuum. The exhaust air is guaranteed to blast filth all over the place. Prevent this ironic tragedy by pumping that dusty air outside with an additional hose hooked up to the exhaust port.
Knock Down Dust with Water
When cutting stone or masonry, have a helper wet down the blade of the circ saw. This will prevent the dust from getting airborne, and the slurry will extend the life of the blade by keeping it cool. A garden sprayer works perfectly for this job.
Caution: Plug the saw into a GFCI-protected outlet or into a special portable GFCI plug.
Low-Dust Joint Compound
Drywall sanding may be the single dustiest process in any remodeling project. While there’s no way to control all the dust, working with a low-dust joint compound will help. Low-dust mud is formulated to fall straight down to the ground instead of floating around. The downside is that low-dust mud is harder to sand than regular mud and can cost 60 percent more, so most pros use it only on smaller remodeling projects and put up with the mess on larger jobs.
Conquer Drill Dust
Here’s a neat little tool that sucks up the dust right at the source. Hook the BitBuddie up to a vacuum and place it over the spot where you plan to drill. This thing lets no dust escape whatsoever, and the suction from the vac actually holds it to the wall! It will also suck up slurry if you’re wet-drilling. The BitBuddie is made by Dustless Technologies and comes with an 18-in. hose.
Nibble Away at Fiber Cement
The dust created from cutting fiber cement siding with a circular saw is not only prodigious; it's also hazardous to your health. If you have a thousand cuts to make, a circ saw is a necessary evil, but if you're just making repairs or installing siding on a small addition, consider cutting with the TSF1 TurboShear made by Malco. This shear attaches to most drills larger than 14.4 volts and creates very little dust as it chews its way through fiber cement siding. It also can cut curves!
