In short
Commercial cleaning across Toronto and the GTA is priced from five main inputs: cleaning frequency, square footage, washroom and kitchen count, floor types, and access requirements. Frequency moves the price more than size does. Most reputable companies quote only after a walkthrough, because a price without a written scope is not comparable to anything.
If you have gathered quotes for office cleaning before, you have probably noticed that the numbers are hard to compare. One vendor quotes a monthly figure, another a per-visit rate, a third asks for square footage and sends back a number with no detail behind it. None of them are necessarily wrong. They are just answering different questions. This guide explains how the pricing actually works, so the quotes on your desk start making sense.
The four pricing models you will encounter
- Per-visit pricing: a fixed rate for each scheduled clean. The most transparent model for recurring office service, because the monthly cost is simply the rate times the schedule.
- Monthly flat rate: one number covering the agreed schedule. Convenient for budgeting, but only meaningful when the scope and visit count behind it are in writing.
- Per-square-foot pricing: common for very large facilities and for rough estimating. For a 2,000-square-foot office it is a blunt instrument. Two offices of identical size can need very different work.
- Hourly pricing: usually a sign the scope is undefined. If the vendor cannot say what will be done, only how long someone will be there, you are buying time rather than an outcome.
What actually moves the price
Square footage is the input everyone asks about, but it is rarely the biggest driver for professional offices. The factors below matter more, which is why a walkthrough beats a calculator.
- Frequency: five visits per week is not five times the price of one because there are efficiencies, but frequency is the single largest lever on your monthly cost in either direction.
- Washrooms and kitchens: these are the most labour-intensive zones per square foot. Two extra washrooms change a quote more than five hundred extra square feet of open office.
- Floor mix: carpet, tile, vinyl, and polished hard floors each need different work, and GTA winters put more pressure on entrance zones.
- Client traffic: a mortgage office with constant appointments needs reception, boardroom, and washroom attention that a quiet back-office of the same size does not.
- Access and timing: after-hours service, alarm procedures, multi-tenant building rules, and parking logistics all shape the labour plan.
- Supplies: whether consumables such as paper, soap, and liners are included, billed separately, or handled by your office.
- Condition at the start: an office that has been undercleaned for a year may need an initial deep clean before recurring service can hold a standard.
Why a low quote is sometimes the expensive one
Cleaning is a labour business with thin margins and, industry-wide, very high staff turnover. A quote dramatically below the others is usually paid back through scope-trimming: fewer tasks done per visit, faster passes, poorly managed staffing changes, and quiet corner-cutting that takes months to notice. The price did not go down; the service did. The defence is not cynicism; it is a written scope. When every quote is attached to a documented task list, the cheap-but-vague number loses its disguise.
How to make quotes comparable
- Ask every vendor for the scope in writing: which rooms, which tasks, at what frequency.
- Ask what is excluded: windows, deep carpet work, supplies, and periodic floor detail.
- Confirm insurance, WSIB compliance, and bonding in the quote itself, not verbally.
- Ask who is accountable for the work, and how the standard survives staff turnover: a written checklist and per-visit proof, or a promise.
- Ask how completion is verified: per-visit reports, periodic inspections, or nothing.
- Then compare monthly totals, but only after the scopes match.
Where Keystone stands
Keystone does not publish a rate card, for the same reason no serious provider does: the walkthrough sets the scope, and the scope sets the price. What is fixed is the process: a walkthrough first, then a written quote within 24 hours that documents rooms, tasks, frequency, exclusions, and service notes, so you can lay it beside any other quote and compare line by line. The walkthrough and the quote cost nothing.
Common questions
Why don't commercial cleaning companies publish prices?
Because identical square footage can mean very different work. Washroom count, floor types, client traffic, access rules, and frequency all change the labour required. A published rate would either overcharge simple offices or underprice complex ones. Vendors often correct that underpricing later through scope-trimming.
Is per-square-foot pricing standard for offices?
It is common for estimating large facilities, but for professional offices between 1,500 and 5,000 square feet, per-visit or monthly pricing tied to a written scope is more typical and far more meaningful.
How do I compare two cleaning quotes fairly?
Match the scopes first: rooms, tasks, frequency, exclusions, supplies, and verification. Only when the scopes describe the same service do the prices become comparable. A lower number attached to a vaguer scope is not a lower price; it is less service.
Does Keystone charge for the walkthrough or the quote?
No. The walkthrough and the written quote are free, and the quote arrives within 24 hours of the walkthrough.
