Hiring a commercial cleaning company is easier than evaluating one. Most providers look similar on the surface — professional websites, reasonable prices, glowing testimonials. The differences that matter reveal themselves only after you have signed a contract and experienced the service for a few months. Here is how to surface those differences before you commit.

Nine Questions to Ask Every Provider

1. Are you fully insured and bonded?

This is non-negotiable. Ask for a certificate of insurance and verify the coverage amounts. General liability of at least $1 million per occurrence is standard. Workers compensation coverage is also essential — if an uninsured cleaner is injured on your property, you may be liable.

2. Do you use employees or subcontractors?

Many cleaning companies win contracts and then subcontract the work to third parties they have never met. This creates accountability gaps: you signed a contract with one company but someone else is entering your building. Ask directly, and get the answer in writing.

3. What does your background check process look like?

Anyone entering your business should have passed a criminal background check. Ask how recently checks are run, whether they cover all states or just the hiring state, and what happens when a check returns a concern.

4. What products do you use by default, and can they be changed?

EPA-approved, eco-friendly products are increasingly the standard — and they matter for employee health and surface compatibility. Ask for a product list and verify any claims about green certification.

5. What is the contract length and cancellation policy?

Month-to-month contracts favor you. Long-term contracts with punitive cancellation clauses favor the provider. Be wary of any contract that locks you in for more than six months without a clear performance-based exit clause.

6. How do you handle missed visits or unsatisfactory cleans?

Every reputable provider should offer a satisfaction guarantee — a commitment to return and make it right within 24 hours of a reported issue at no additional cost. Ask how this works in practice, not just in principle.

7. Who is my point of contact, and how quickly do you respond to issues?

A direct phone number and a named account manager matters more than you might expect. When something goes wrong, you need to reach a person — not leave a voicemail for a general inbox.

8. Can I speak to a reference in a similar industry?

Any established cleaning company should be able to provide three references from businesses similar to yours in size or industry. Follow up on them. Ask specifically about consistency, communication, and how the provider handled problems.

9. What does a sample scope of work look like?

Ask to see the actual document they would use to guide cleaning at your facility. A vague scope is a recipe for disappointment — a detailed scope is a sign of professional discipline.

Red Flags to Walk Away From

  • Unable to provide a certificate of insurance on request
  • Prices significantly below every other quote (usually means something important is excluded)
  • No mention of background checks or hesitation when asked
  • Guarantees that sound too comprehensive to be credible
  • No named account manager or direct contact

The Right Fit

The best cleaning service for your business is not necessarily the cheapest or the most expensive. It is the one whose scope matches your actual needs, whose communication culture matches yours, and whose processes are specific enough to deliver consistency at scale.
