Drywall and construction dust behaves differently from everyday household dust — it’s finer, settles into HVAC systems, and can resurface for weeks after a standard clean if not addressed properly. New homeowners across the GTA often underestimate how much of it there actually is until they run a cloth along an untouched shelf.
Where Construction Dust Hides
- Inside HVAC vents and ductwork, where it recirculates through the home every time the system runs
- On top of cabinets, door frames, and crown moulding — areas easy to miss without looking up
- Inside light fixture covers and ceiling fan blades
- Within carpet fibers, if any carpet was installed before major construction work finished
The Right Cleaning Order
Cleaning construction dust effectively means working top to bottom — ceilings and light fixtures first, then walls and surfaces, then floors last — so dust that gets dislodged from higher areas doesn’t resettle on surfaces you’ve already cleaned.
HVAC Considerations
Changing or cleaning the HVAC filter after major construction dust settles is important, since a clogged filter from initial dust buildup reduces air quality and system efficiency going forward. In some cases, a full duct cleaning is worth considering for a newly built home before regular use begins.
Why a Single Pass Isn’t Enough
Because construction dust continues to settle out of the air for some time after major work finishes, homeowners often need a follow-up clean a few weeks after move-in to catch dust that wasn’t airborne during the first clean.
My Canada Cleaning specializes in construction dust removal for new GTA homes, using a systematic top-to-bottom approach that gets ahead of resettling dust.
