Most businesses don't switch cleaning companies because of price. They switch because of the slow fade: great for a month, fine for two, then missed garbage bins, streaky glass, and a washroom complaint from a client you really didn't want noticing. If you're vetting cleaners in Winnipeg — whether it's your first vendor or your fourth — these twelve checks will separate companies built to last from companies built to win the quote.
The paperwork checks (dealbreakers)
1. WCB coverage. In Manitoba, if a cleaner is injured at your site and their employer isn't covered, the liability exposure can reach you. Ask for proof of WCB compliance — a legitimate company produces it within a day.
2. Commercial liability insurance. $2M general liability is the standard for commercial work. If your building requires it, ask whether they can add your company as an additional insured — larger property managers often need this, and vendors who handle it routinely will say so immediately.
3. A written scope of work — before you sign. This is the single most predictive document. Every task, every area, every frequency, on paper. Without it, every future complaint becomes a negotiation about what was "supposed" to be included. A vendor who quotes without walking your space is guessing — and pricing their guess defensively.
4. WHMIS-trained staff. Cleaning crews handle chemicals in your workplace. WHMIS training is the baseline; for industrial sites, ask about fit-testing and site-safety orientation too.
The accountability checks (where the fade begins)
5. Who inspects the work? Not "who do I call when it's bad" — who proactively checks it when you're not looking? Supervisor inspections, site checklists, photo proof of visits: any of these systems works. The absence of all of them is how the slow fade starts.
6. One named contact. Franchise call centres route your complaint to a queue. Ask: "If the washroom is missed on Tuesday, who do I text?" You want a name, not a 1-800 number.
7. What happens when something IS missed? The honest answer involves a documented correction, not a promise. Ask to see what a corrective action looks like in their system. If there's no system, the answer is really "we apologize until you leave."
8. Cleaner turnover. High-turnover vendors permanently re-train strangers in your space. Ask how long their crews stay and whether the same people clean your site each visit. Consistency of people is consistency of results — and it matters for security, too.
The fit checks
9. Do they clean spaces like yours? Office cleaning, industrial common areas, clinics, and rec facilities are different jobs with different standards. Ask specifically about spaces like yours — and be suspicious of anyone who says yes to everything, including the things they've never done. (A vendor who tells you what they don't do is showing you they'll be honest about the rest.)
10. After-hours capability. If crews can only come during business hours, your team absorbs the disruption forever. Evening and early-morning capability should be standard for commercial work.
11. Contract terms. Long-term lock-in contracts protect vendors from the consequences of declining quality. Month-to-month or short renewal terms mean the company plans to earn the renewal with the work. Ask why the contract is as long as it is.
12. Local reviews and references. Ask for two current commercial references in Winnipeg — similar size, similar space. Then actually call one. The question that gets honest answers: "What do they miss, and what happens when they do?" Every vendor misses things; the good ones have a boring, documented answer to the second half.
The one-question shortcut
If you only have time to ask one thing, use this: "Show me how I'll know the work was done to standard in month six." Everything above collapses into that answer. Vendors with real systems — scopes, checklists, inspections, photo proof — will show you something concrete. Vendors without them will tell you about their work ethic.
Where we're honest about ourselves
This checklist is also how we'd tell you to vet us. Shift Clean is Winnipeg-owned, WCB compliant and $2M insured, and every account runs on a written scope with supervisor inspections and photo-proofed visits — because we built the company around the month-six problem. We're a strong fit for offices, clinics, and small commercial buildings and industrial common areas; we're the wrong fit for production-line, cleanroom, or biohazard work, and we'll tell you so and point you to a specialist.
If you're comparing vendors right now, a free walkthrough gets you a written scope and price within 48 hours — which also makes a handy benchmark for every other quote on your desk.
