How much does final cleaning cost per square foot for new construction in Ottawa?

Some cleaning companies in Ottawa quote post-construction final cleaning by the square foot, and quotes for residential new builds can run roughly $0.50 to $1.50 per square foot. Treat that as perspective before you have real quotes, not a price list. Where your project falls depends on several factors including the complexity of the construction, the types of finishes installed, the number of windows, and whether the rough clean was already completed separately.

Toward the lower end, you are usually looking at a standard final clean for a straightforward new build with common finishes — laminate or vinyl plank flooring, standard tile in bathrooms, builder-grade fixtures, and a moderate number of windows. This level of service covers a thorough top-to-bottom interior clean including all surfaces, basic window cleaning, floor washing, fixture wiping, and cabinet interiors.

Homes with more detailed finishes — hardwood flooring that requires careful product selection, natural stone countertops, larger window packages, and custom cabinetry — tend to price higher, because crews spend more time on detail work and use surface-specific products.

The upper end usually covers luxury homes, custom builds, and properties with high-end finishes that demand white-glove treatment. Marble floors, floor-to-ceiling windows, custom millwork, designer fixtures, and architectural details all increase the time and care required, as do older homes with delicate period materials.

Keep in mind that a per-square-foot rate often covers the final clean only — not the rough clean. The rough clean, which is the initial heavy cleanup done while construction is wrapping up, is usually priced separately and should be completed before the final clean crew arrives. Certain services are also often quoted separately from the per-square-foot rate, such as HVAC duct cleaning, exterior pressure washing, and detailed window cleaning beyond a basic wipe-down. Duct cleaning is worth considering if construction happened during Ottawa's heating season, when a running furnace can circulate fine dust through the ductwork.

Always request itemized written quotes from a few companies so you can compare what is included at each price point. Ask for proof of liability insurance and what it covers, and ask whether they have WSIB coverage or a clearance certificate. The Ottawa Construction Network directory at justynrookcontracting.com lists cleaning contractors in the Ottawa area and is a useful starting point for getting competitive quotes.
