What Commercial Cleaning Actually Costs Per Square Foot in the GTA
By Probello Facility Services · March 3, 2026 · 7 min read
Price per square foot is the shorthand of this industry, and it hides more than it reveals. The same 20,000 sq ft office can be quoted three different ways depending on how many washroom fixtures are in play, how much of the floor is carpet, and whether the crew is expected to restock consumables.
What moves the number
- Washroom fixture count — the single biggest labour driver in most offices
- Hard floor versus carpet mix, and how much of it is high-visibility
- Service frequency and shift window (after-hours premiums are real)
- Consumables: supplied by the vendor or billed separately
- Access and logistics: loading dock, elevator booking, security escorts
How to compare quotes fairly
Ask every bidder to price the same written scope, with frequency stated per space type rather than nights per week. When the scope is identical, the spread between quotes tells you something real about staffing assumptions rather than about who wrote a prettier proposal.
A cheap quote is usually not a discount. It is fewer hours, and you will find out where.
If you want a written scope you can hand to other bidders, book a walkthrough. We will document space by space and send pricing within one business day.
