The old way vs. the CleanerOffices way.
Most cleaning companies sell you a crew. We sell you a system — and the difference shows up on the days something goes wrong.
A crew and a promise
- A night gets skipped — you hear about it from staff first
- Someone's off sick and nobody covers
- Quality depends on who showed up that night
- No proof of what was actually cleaned
- You chase the company; emails get lost
- Hidden costs surface after you sign
A system you can see
- Substitute coverage — a trained backup steps in, no gap
- Photos where it counts, every visit clocked in and out
- Scored inspections — we catch issues before you do
- A dedicated manager on a direct line, not a ticket queue
- One clear quote from a walkthrough — no surprises
- Insured & CNESST-compliant, $5M liability

You're not hiring a cleaner — you're plugging into a system. The real value is the operations layer underneath — so nothing depends on someone's memory; it depends on the system. The same six systems run at every Montreal client, from a single office to portfolios over a million sq ft. You get full visibility into all six, from day one.
