10 Questions to Ask Before Hiring a Commercial Cleaning Company

Set Expectations Before You Bid

A polished proposal doesn’t guarantee reliable service. Ask these ten questions to separate professional providers from the rest.

1. Are cleaners W-2 employees or contractors?

Employee-based models (like Anderson’s) allow consistent training, background checks, and benefits. Contractors can create gaps in accountability.

2. What is your onboarding process?

Look for documented walkthroughs, custom SOPs, and a formal transition plan—especially if you’re switching vendors mid-contract.

3. Can you provide proof of insurance?

Request certificates for general liability, workers’ compensation, and umbrella coverage. Confirm limits meet your landlord or corporate requirements.

4. How do you handle staffing shortages?

Professional firms maintain float teams and cross-train employees so absences don’t derail your cleaning schedule.

5. What is the communication structure?

Ask where you submit requests, how quickly you’ll get a response, and who performs inspections.

6. Which chemicals and equipment do you use?

Providers should specify EPA-registered disinfectants, HEPA vacuums, and microfiber systems—and be able to supply SDS sheets on request.

7. How do you protect keys, badges, and alarm codes?

Your vendor should have chain-of-custody procedures and secure storage for credentials.

8. Do you offer specialty services?

Floor care, carpet extraction, window cleaning, and supply management should be available as add-ons so you’re not coordinating multiple vendors.

9. Can you share references in my industry?

Testimonials from similar facilities—medical, corporate, education—prove the team understands your compliance needs.

10. What happens if we’re not satisfied?

Look for service-level guarantees, corrective action timelines, and an easy exit clause if things go sideways.
