What areas of my new home are most often missed during post-construction cleaning?

Even after a professional post-construction clean, certain areas of a new home are frequently overlooked or inadequately addressed. Knowing what to check helps you ensure nothing gets missed — whether you are doing a final walkthrough after the cleaning crew finishes or evaluating the thoroughness of the job yourself.

HVAC ducts, registers, and return air vents are easy to miss. Construction dust can settle inside ductwork, and while cleaning crews typically wipe the visible vent covers, the dust inside the ducts themselves usually calls for a separate duct cleaning service, quoted on its own. If this is skipped, your furnace or air conditioner can blow fine construction dust back onto surfaces in the home, undoing some of the surface cleaning. This matters most for Ottawa homes built or renovated during winter, when the heating system may have been running throughout construction.

Inside cabinets, drawers, and closets are frequently given a quick wipe rather than a proper clean. Open every cabinet and drawer after the cleaning — you will often find a fine layer of dust on shelves, construction debris in corners, and dust on the hinge mechanisms. Upper kitchen cabinets and the tops of tall closets are particularly prone to being missed because they require a step stool or ladder to reach.

Window tracks and weep holes get overlooked even when the glass itself is cleaned. Construction dust, drywall crumbs, and small debris pack into the bottom tracks of sliding and casement windows. Weep holes — the small drainage openings at the bottom of window frames — can become clogged with construction dust, which can lead to water problems if they fail to drain properly. Check every window track after cleaning.

Behind and underneath appliances is a blind spot. Refrigerators, stoves, dishwashers, and washers and dryers may have been installed before the final clean, and the floor and wall areas behind them collect dust and debris. Light fixtures, particularly recessed pot lights, gather dust inside the housing that is not visible from below but becomes noticeable when the lights are on. Outlet and switch plates can also hold drywall dust around their edges — wipe the plates, but leave anything behind them to an electrician.

Baseboards and the gap between baseboards and flooring trap fine dust that is hard to see but easy to feel when you run a finger along them. Door hinges and the tops of door frames collect dust that is above eye level and easy to miss. Attic hatches and crawl space access panels are easy to overlook during post-construction cleaning. Garage interiors — if the garage was used as a staging area during construction, it often contains significant dust and debris that does not get addressed in a standard interior clean.

After your cleaning crew finishes, do a walkthrough with a damp white cloth and run it along surfaces like cabinet tops, window tracks, baseboards, and light fixture housings. This is the quickest way to identify areas that need a second pass. Before you hire, ask whether the company will come back to address missed spots if you report them promptly, and get that in writing.
