What type of vacuum do I need to properly clean construction dust from carpets in Ottawa?

You need a vacuum with true HEPA filtration to properly clean construction dust from carpets. It is the difference between removing fine construction dust and simply spreading it around your home. A HEPA filter is designed to trap the very fine particles produced by drywall sanding, concrete grinding, and wood cutting. Many standard household vacuums without HEPA filtration can let those particles pass through the filter and blow back into the room, sometimes as a visible dust cloud behind the machine.

For construction dust, look for a vacuum with a sealed HEPA system, meaning the airpath from intake to exhaust is sealed so air can only leave through the HEPA filter. Some vacuums have a HEPA filter but leak dust through joints and seams in the body, which defeats the purpose. Commercial HEPA vacuums cost considerably more than household models, so for a one-time post-renovation cleanup, renting one from an equipment rental company in the Ottawa area is often the most cost-effective option — call ahead for daily rates.

Construction dust is a challenge for carpets because the particles are very fine and work deep into carpet fibres and the pad underneath. Surface vacuuming, even with a HEPA machine, only removes dust from the top layer of the carpet pile. Effective cleaning requires slow, deliberate passes with the vacuum's beater bar or rotating brush engaged. Make multiple passes in overlapping lines, then rotate 90 degrees and make another set of passes perpendicular to the first. This cross-pattern technique dislodges dust from fibres oriented in different directions. Expect to need several complete vacuuming sessions spread over a week or two before most of the construction dust is out of the carpets.

In Ottawa, winter renovations mean carpets collect construction dust during the driest months of the year, when heated indoor air does little to help fine dust settle. Keep the furnace filter fresh and run HEPA air filtration while you work through the vacuuming sessions, so dust you stir up is caught rather than settling back into the carpet.

Even after thorough HEPA vacuuming, carpets exposed to heavy construction dust often benefit from hot-water extraction cleaning, commonly called steam cleaning. This process flushes hot water and cleaning solution into the carpet fibres, then extracts the dirty water along with embedded dust that a vacuum can't reach. Quotes for carpet extraction after construction in Ottawa can run roughly $200 to $500 depending on the area covered — ask for an itemized written quote. For heavy dust, combining HEPA vacuuming with extraction usually gives the best result.
