How to evaluate a commercial cleaning company before you sign

Published by the ABR team · Updated September 2026

Key takeaways
  • Before a walkthrough, verify the vendor's certificate of insurance directly with their agent, plus general liability and workers' compensation coverage.
  • Ask who exactly will clean your building, how crews are trained, what the visit checklist looks like, and how work is verified.
  • Walk away from vendors who can't produce a building-specific checklist or a named point of contact.

Yes — we're a cleaning company telling you how to vet cleaning companies. We're publishing this anyway, because the questions below are the ones a well-run vendor wants to be asked, and the ones a poorly run one hopes you skip. Use them on us. Use them on everyone.

Before the walkthrough: paperwork that actually matters

The 12 walkthrough questions

  1. Who exactly will clean my building? The same crew nightly, or whoever's available? Consistency is the single biggest quality driver.
  2. How are crew members screened and trained? "We hire experienced people" is not a training program. Ask to see the curriculum or checklist they're trained against.
  3. What does a visit checklist look like? If they can't produce a building-specific checklist, quality depends entirely on memory.
  4. How do you verify the work was done? Initials, inspection scores, photos — anything documented beats "trust us."
  5. Who is my point of contact, and what's the response time? Get a name and a number, not a ticket portal alone.
  6. What happens when something is missed? The honest answer includes a re-clean policy with a timeframe.
  7. What products do you use, and can I see the SDS sheets? Green Seal or EPA Safer Choice certification matters in occupied buildings; safety data sheets should be available without hesitation.
  8. How do you prevent cross-contamination? Listen for color-coded cloths and separate restroom mops. Silence here is a red flag.
  9. What is and isn't in scope? Get the exclusions in writing — interior windows, dishes, high dusting frequency. Most disputes live in the gray area.
  10. How is pricing structured, and what triggers a change? Square footage, frequency, and supply costs should be itemized.
  11. What's your client retention rate? Renewal percentage tells you more than any reference call.
  12. Can I speak to a client of similar building type? A medical office reference means little if you run a warehouse.

Red flags worth walking away from
