How many cleaners are usually needed for post-construction cleanup of a large Ottawa home?

For a large Ottawa home, a post-construction cleaning crew is often three or more cleaners, though this varies with the scope of work, the condition of the home, and how the company schedules its jobs. Smaller homes may need fewer people, and very large custom homes may call for a bigger team. There is no fixed rule, so ask each company how many people they plan to send.

Why Crew Size Matters for Post-Construction Cleaning

Post-construction cleaning is far more labour-intensive than regular house cleaning. A bigger home means either a longer day for the same crew or a larger team to complete the work in a reasonable timeframe. Many companies prefer to send a larger crew and finish in one day rather than spread the work over several, because construction dust can resettle overnight and partially undo the previous day's work, particularly if air scrubbers are not left running.

A crew often divides into roles rather than everyone doing the same task. One or two team members may handle the HEPA vacuuming and air scrubbing, working through the home systematically from top to bottom. Another team member focuses on wet cleaning, including washing walls, wiping down cabinets and fixtures, and scrubbing countertops and tile surfaces. A dedicated person usually handles window cleaning, which is slow, detail-oriented work that benefits from a specialist. On large homes with significant glass, this person may work all day on windows alone. The crew lead manages quality control, doing spot checks behind each team member and handling any delicate surfaces that require particular care.

Ottawa's winters add a factor that affects crew requirements. Homes built or renovated during the winter months can have more widespread dust, because dry indoor air during heating season lets fine construction dust stay airborne. A heating system running during construction can carry this dust throughout the home, so rooms, vents, and cabinet interiors may need intensive cleaning even where no construction happened. A winter-built home may need a bigger crew or more time than a summer build of the same size.

When evaluating quotes, pay attention to the crew size and estimated hours included. A very small crew for a large new build may mean the company is underestimating the scope or planning to take multiple days, which brings back the resettling dust problem. Conversely, an unusually large crew crammed into a home can be inefficient and raise the risk of equipment damaging fresh finishes. Look for a clear plan with defined roles and a systematic room-by-room approach. Ask the company for proof of liability insurance and what it covers, and ask whether they have WSIB coverage or a clearance certificate.
