What is the best way to clean up drywall dust after a basement renovation in Kanata?

Drywall dust is one of the most persistent and frustrating byproducts of any basement renovation, and cleaning it properly requires a specific approach that is easy to get wrong on the first attempt. The most important rule is this: avoid using a regular household vacuum on drywall dust. A vacuum without HEPA filtration can let the very fine particles pass through the filter and blow back into the air through the exhaust, so you end up spreading the dust rather than removing it. A HEPA vacuum is the better tool for the job.

A good cleaning sequence for a basement after drywall work is top to bottom, dry before wet. Start by running an air scrubber if you have access to one, as fine drywall particles can stay suspended in the air for some time after the last disturbance. HEPA vacuum the ceiling first, including around pot lights, bulkheads, and any HVAC registers. Then vacuum walls from top to bottom. Next, vacuum all horizontal surfaces including window sills, ledges, framing, and the floor. Only after thorough dry vacuuming should you switch to damp cleaning. Use a barely damp microfibre cloth on walls and surfaces, rinsing frequently in clean water. For the floor, damp mop with clean water, changing the water often because drywall dust turns into a gritty paste that will scratch new flooring if you push it around in dirty water.

Basements bring a specific challenge. If your home has a forced-air system with return vents in the basement, drywall dust can be pulled into the ductwork during the renovation. If the work happened during the winter heating season when the furnace was running, HVAC duct cleaning is worth serious consideration. Ask for it to be quoted separately, and schedule it so it does not spread dust onto freshly cleaned surfaces.

Ottawa's dry winter air makes drywall dust especially troublesome in cold months, because fine particles stay airborne more easily. If your renovation wrapped up in winter, plan for a second cleaning pass a day or two after the first, because dust that settled in cracks and crevices can keep emerging as people walk through the space and air circulates.

For a small drywall patch in a basement laundry room, you can manage cleanup yourself with a rented HEPA vacuum and plenty of microfibre cloths. But for a full basement finish, hiring a cleaning company is usually worth it. Quotes for post-drywall cleaning of a finished basement can run roughly $500 to $1,200, depending on size and how much dust there is — ask for itemized written quotes. A cleaning crew brings commercial HEPA vacuums, air scrubbers, and the experience to clean new surfaces without damaging them.
