How do I verify that the final clean meets Ontario building standards before moving in?

The practical way to verify a final clean is your own careful walkthrough before you accept the work. A building inspection is about whether the work itself is built properly, so do not expect an inspector to grade how well the house was cleaned. If you have questions about inspections or occupancy for your permit, check with the City or ask your builder or contractor, rather than relying on a cleaning company to tell you what the rules are.

What you can control is the standard you agree on with the cleaning company. Before the job, get a written scope that lists every room and surface to be cleaned, so you have something concrete to check against when the crew is done.

Then conduct your own detailed walkthrough inspection before signing off on the final clean. Start from the highest point in the home — check ceiling fixtures, pot lights, and the tops of door and window casings for dust. Run a white cloth along flat surfaces to check for residual construction dust. Open every cabinet, drawer, and closet to inspect inside. Check all windows from multiple angles in natural light to spot paint overspray, adhesive residue, scratches, or missed stickers. Inspect floor surfaces on your hands and knees looking for grout haze, adhesive spots, and scratches.

Air quality is an often-overlooked component of a proper final clean. Fine construction dust particles can stay airborne for a while after being disturbed, and many are too small to see. Ask whether the crew will run air scrubbers with HEPA filtration during and after the cleaning process. You can verify air quality informally by looking at sunlight streaming through windows — visible particles floating in the light indicate that airborne dust has not been adequately addressed. If you have concerns about air quality, a portable indoor air quality monitor that measures fine particulate can give you a rough reading to compare over a few days.

Check the HVAC system by removing a vent cover and looking inside the duct opening. Visible dust or debris inside the ducts means construction particulate can recirculate every time the furnace or air conditioner runs. With Ottawa's long heating season and humid summers, the system runs much of the year, so dusty ductwork can undo your surface cleaning. If duct cleaning was not in your quote, it is worth asking about separately.

Document everything with photos and a written checklist during your inspection. If you find deficiencies, communicate them in writing to the cleaning company and give them a reasonable opportunity to return and address the issues. For a new build, note cleaning problems during your pre-delivery inspection (PDI) with the builder as well. If you need to hire a crew to bring the clean up to standard, the Ottawa Construction Network directory at justynrookcontracting.com lists post-construction cleaning companies in the Ottawa area.
