- The biggest red flags are no walkthrough, no proof of insurance, no written scope and a price far below the rest.
- Pressure to sign quickly or a long lock-in without an exit clause should slow you down.
- Reluctance to answer basic questions is itself an answer.
Most bad cleaning experiences were visible before the contract was signed. These are the warning signs worth taking seriously.
1. A quote without seeing the building
Nobody can price your space accurately from a phone call or a form. A real quote needs square footage, restroom count, floor types and a talk about your expectations.
2. No proof of insurance
A legitimate company can send a certificate of insurance quickly. If they hesitate, change the subject or say they will "get to it later," stop. See commercial cleaning insurance explained.
3. A price far below everyone else
Cleaning is a labor business. When a bid is much lower than the others, something is missing: fewer hours, fewer visits, workers paid off the books, or supplies not included. Ask what the low bid leaves out.
4. No written scope of work
If the scope is verbal, it is hard to hold anyone to it. A written scope protects both sides.
5. Vague answers about who will clean
If the company cannot say whether they use employees or subcontractors, or who will be on your site, you may end up with a different person every night.
6. No quality-control process
Ask how work is checked. If the answer is "we hope you'll tell us," quality depends on you finding the problems.
7. High-pressure sales tactics
"This price is only good today" is a sales tactic, not a business reason. A good company lets you compare.
8. A long contract with no exit
Lengthy lock-ins with heavy cancellation penalties transfer all the risk to you. Look for a reasonable termination clause after an initial period. See what a cleaning contract should include.
9. Only reviews, no references
Reviews help, but they can be incomplete or manipulated. Ask for a reference from a similar building. See can you trust online reviews?
10. Hesitation on basic questions
How they respond to your questions is the best preview of how they will respond to your problems.
If you see two or three of these, keep looking. There are good companies that welcome the questions.
