The 17 warning signs that you have the wrong commercial cleaning vendor, or that the vendor you’re about to sign with is going to disappoint you. Written for facility managers in CT and RI who got burned and don’t want to repeat it.
Most commercial cleaning vendor relationships fail in predictable ways. After 39 years of operating bank, healthcare, manufacturing, and office cleaning programs across eastern Connecticut and southern Rhode Island, the failure patterns repeat. If your current vendor is showing any 3 or more of these red flags, it is time to start a procurement process. If a vendor you are evaluating shows any of these patterns during procurement, walk away.
Red flags during procurement (before you sign)
1. They quote without walking your building
Reasonable vendors do a free walkthrough before quoting. Vendors who quote sight-unseen are guessing, and the quote will need to be revised once they see the actual scope, or worse, they will understaff your account based on the wrong assumptions.
2. The bid is more than 30 percent below market
For a 10,000 sq ft office on 5-night janitorial in CT or RI, market rate is $1,500 to $2,500 per month. A bid of $900 means one of two things: they will understaff your account (so you get bad service starting month 2), or they will raise prices aggressively after year one. Both end the same way.
3. They cannot produce a sample certificate of insurance within 24 hours
Bonded, insured commercial cleaning vendors carry COIs as part of their standard sales kit. If they cannot produce one quickly, it usually means the documentation does not exist yet or is out of date.
4. The proposed scope of work is vague
“Standard cleaning of office areas” is not a scope of work. A real scope lists every task, every area, and every frequency. Vague scope is the leading cause of contract disputes, six months in, you are arguing about whether something was supposed to be cleaned.
5. The named supervisor is not actually named
“Your supervisor will be assigned at contract signing” is a red flag. The supervisor should be named in the proposal, with a phone number, with their other accounts disclosed, and with their tenure stated.
6. References are vague or refused
Industry-specific references should be three minimum, with current contact information, named contacts, and verifiable. Vendors who push back on references usually do not have happy current clients to point at.
7. They cannot describe their backup coverage procedure
What happens if your assigned cleaner is sick? If the answer is “we will figure something out,” they will not figure something out, your building will get skipped or get a substitute who does not know the scope.
8. The proposal is generic, your name in mail-merge fields
Real proposals are written for your facility. Look for references to your specific square footage, area types, restroom count, industry compliance requirements, and walkthrough findings. Generic proposals signal generic service.

9. The supervisor never walks the building with you
Standard practice: monthly walk-through with the supervisor signing off on a written report. If you have never met your supervisor or it has been more than 60 days since the last walk-through, supervision has lapsed.
10. Cleaner turnover at your account is constant
Industry average annual turnover is above 75 percent. The good vendors hold turnover under 50 percent. If your assigned cleaner changes every two months, you are getting whatever crew the vendor has available, not a dedicated team.
11. Restrooms look bad by midweek
Walk your restrooms on a Wednesday at 2pm. If they look tired, the cleaning is missing the documented scope. If you bring it up and it is fixed for one week then drifts again, the supervisor is not enforcing the standard.
12. You find dust on horizontal surfaces above shoulder height
Detail dusting (window sills, door tops, picture frames, supply room shelves, light fixtures) is in every documented scope. If you can write your name in dust on top of a file cabinet, the crew is skipping it. Confront once; if it does not improve in 30 days, the vendor is unfixable at this account.
13. Trash and recycling get mixed
If your facility separates recycling from trash and the cleaning crew co-mingles them in the dumpster, they are not following the scope. This is a small thing that signals a bigger thing: the crew is rushing.
14. Conference rooms are not reset between meetings
For day porter or after-hours: rooms should be reset (chairs in place, table wiped, glass cleaned, supplies restocked). If you walk in to a meeting and the previous meeting’s coffee cups are still on the table, the scope is being skipped.
15. You receive monthly invoices but no monthly reports
Standard practice: monthly walk-through reports, restroom check-off sheets, and any incident or scope-change documentation routed to you with the invoice. If you only get invoices, the vendor is operating without accountability documentation.
16. The supervisor is unreachable when you have an issue
Standard expectation: supervisor reachable within 30 minutes during business hours, within 2 hours after-hours. If you are leaving voicemails and waiting 24+ hours for callbacks, the vendor’s supervisor structure is broken.
17. Annual price increases above 5 percent without justification
Reasonable contracts include a CPI-tied or capped escalator (typically 3-5 percent). Increases of 8-15 percent without specific justification (new minimum wage, scope expansion, regulatory cost) signal the vendor is testing how much you will tolerate.
What to do when you spot 3 or more
- Document specific instances with dates, times, and photos where applicable.
- Have a direct conversation with the supervisor and/or account manager. Give them a documented 30-day cure period with specific expected improvements.
- If the cure period passes without genuine improvement (not just one good week), start a formal procurement process per your contract notice terms.
- Use the cure period to walk other vendors through your facility and collect competitive bids.
- Time the transition to your contract notice window. Most cleaning contracts allow 30 to 60 days notice for non-cause termination.
The vendors who do not have these red flags
The cleaning vendors that consistently deliver share five operational traits:
- Documented scope of work per account, signed by both parties at contract execution.
- Named supervisor with a reasonable account ratio (12-15 accounts per supervisor maximum).
- Cleaner tenure tracked and disclosed. Industry-leading vendors hold turnover under 50 percent.
- Monthly walk-through reports as a default, not a request.
- Backup coverage built into the schedule, not improvised when problems happen.
