To vet a commercial kitchen cleaning company, verify four things: proof of insurance and bonding, background checks on everyone who enters your building, references from kitchens like yours, and the documentation that proves the work actually happens. A company that clears all four is worth a contract. A company that stumbles on any one of them is a bet you’re placing on faith.
Most owners stop at the quote and a walkthrough. That’s how a restaurant ends up with a cleaner who looks fine on paper while grease builds in the exhaust system for a year. And there’s one document that tells you more about a kitchen cleaner than every sales pitch combined, yet almost nobody asks to see it.
Why Vetting a Kitchen Cleaner Is a Different Job
Hiring a cleaner for an office is a service decision. Hiring one for a commercial kitchen is a safety decision, and the stakes are set by three things no office ever deals with.
- Fire risk: grease buildup in hoods and ducts is one of the leading causes of restaurant fires. The crew you hire is your first line of defense against it, which is why the NFPA 96 fire code requires exhaust systems to be cleaned by trained, certified personnel on a set schedule.
- Health inspections: your cleaner’s work quality shows up on your inspection report with your name on it, not theirs. An inspector doesn’t care who was supposed to degrease the floor drains.
- After hours access: kitchen cleaning happens at night. You’re handing keys and alarm codes to people you’ll rarely see, working unsupervised around your equipment, your inventory, and sometimes your office.
That combination is why the generic advice about hiring cleaners doesn’t go far enough for a restaurant. The vetting has to be tighter, and it starts with paper, not promises.
Verify Insurance and Bonding Before Anything Else
Never accept “we’re fully insured” as a sentence. Ask for a certificate of insurance, and ask for it to be sent directly from the company’s insurance agent rather than handed over as a photocopy. A legitimate company arranges that in a day.
Three coverages matter for kitchen work:
- General liability covers damage the crew causes: a cracked cooktop glass, an overspray that ruins a dining room finish, a slip caused by a wet floor they left unsigned.
- Workers’ compensation covers their people getting hurt on your property. Pennsylvania requires it for companies with employees, and it matters because kitchen cleaning involves ladders, degreasers, and hot equipment. If an uninsured cleaner’s employee gets injured in your kitchen, the claim can land on you.
- A janitorial bond covers theft by the cleaning staff. Bonding is cheap for the cleaner to carry, so a company without it is telling you something about how seriously it takes the risk.
One step almost nobody takes: ask to be listed as a certificate holder on the policy. It costs the cleaner nothing, and it means the insurer notifies you if the policy lapses mid contract. A company that resists that request is worth a second look, because coverage that quietly expired is the same as no coverage.
While you have the paperwork out, confirm the business is registered in Pennsylvania. It takes two minutes on the state’s business search and filters out the fly by night operations that appear and disappear between seasons.
Background Checks: Know Who’s in Your Kitchen at 2 AM
Every reputable cleaning company will say it screens employees. The useful information is in the follow up questions, so ask all three:
- Ask whether every employee gets checked or only some roles. The person scrubbing your fryer at midnight matters as much as the supervisor who did the walkthrough.
- Ask what the check covers: criminal history only, or also identity verification and references. The answer tells you whether screening is a process or a checkbox.
- Ask when it was last run. A check from three years ago, never updated, tells you less than it seems to.
Just as important is who those people actually work for. A company using its own W2 employees controls hiring, training, and supervision, and usually keeps people longer. A company that subcontracts crews can’t fully vouch for who shows up, because it didn’t hire them.
Subcontracting a specialty job like hood cleaning is normal; subcontracting the nightly crew that holds your keys is a different matter. Ask directly, and ask whether the same crew will come every night. Consistency is both a security measure and the single biggest driver of cleaning quality.
Employee tenure is the quiet signal here. Cleaning is a high turnover industry, so a company with people who’ve stayed five or more years is doing something right, and those veterans are usually the ones trusted with restaurant accounts.
References and Real Reviews: Two Different Checks
References and online reviews get lumped together, but they answer different questions. Do both.
References tell you how the company performs over time. Ask for two or three, and push for at least one food service account, because an office reference can’t tell you how the crew handles grease, drains, or a health inspection cycle. When you call, skip “were they good” and ask:
- Did the same crew show up on schedule, month after month?
- When something was missed, how fast was it fixed, and did it stay fixed?
- Have your inspection results changed since they started?
- Would you sign with them again tomorrow?
Reviews tell you how the company handles accounts you’ll never call. Read the middle ones, not just the five star wall. Detailed reviews that name specific services carry more weight than one line praise, and the owner’s responses to critical reviews show you exactly how complaints get treated.
Then ask the company itself about a complaint it received and how it was resolved. Every cleaner who’s been around has had one, so a company that claims it’s never had a complaint is answering a different question than the one you asked.
The Documentation That Proves the Work Happens
That one document worth more than the sales pitch: the kitchen exhaust cleaning certificate. Under NFPA 96, whoever cleans your hood and duct system must be trained and certified for it. Each service must produce a certificate recording the date, the areas cleaned, the condition found, any deficiencies, and the technician’s name and certification. A sticker on the hood shows the next service date, and your fire marshal and your insurer both know to look for it.
Ask a prospective cleaner to show you a recent certificate from another account, with the client’s name covered. A real one takes thirty seconds to produce. Hesitation means the certificates may not exist, and after a grease fire, that’s the first document an insurance adjuster requests.
Day to day work needs its own paper trail:
- Service logs or checklists signed off per visit, tied to the scope in your contract, so “we cleaned last night” is verifiable. A written scope that spells out daily, weekly, and monthly tasks, like a proper restaurant cleaning checklist, is what makes those logs mean anything.
- Before and after photos for deep cleans and floor work.
- A named contact who answers after hours, because kitchen cleaning problems surface at night.
A company that documents its work is also a company you can hold accountable without an argument. The paperwork isn’t bureaucracy; it’s the difference between a vendor and a professional.
How to Vet a Commercial Kitchen Cleaning Company in One Week
You can run the whole process in five working days without it swallowing your schedule.
- Days 1 and 2: collect quotes from three companies with a written scope of work. If one bid is far below the others, the money is coming out of labor, products, or corners; the restaurant cleaning cost guide shows what realistic pricing looks like in Pennsylvania.
- Day 3: request certificates of insurance sent from each company’s agent, and confirm state registration.
- Day 4: call references and read reviews using the checks above.
- Day 5: hold a walkthrough and ask about background checks, subcontracting, crew consistency, and training. A company that trains seriously can explain its process in detail, down to which sanitizers are used where and at what concentration, the kind of standards covered in a full restaurant sanitation program.
Then decide by elimination. If a company can’t produce insurance certificates, it’s out. If it can’t name a food service reference, it’s out. If it can’t explain its background checks or its training, it’s out.
Whoever is left standing has earned the contract, and the exercise usually leaves exactly one name.

Frequently Asked Questions
Should a commercial kitchen cleaning company be bonded and insured?
Yes, both. Insurance (general liability plus workers’ compensation) covers damage and injuries, while a janitorial bond covers theft by cleaning staff. Ask for a certificate of insurance sent directly from the company’s agent, and ask to be listed as a certificate holder so you’re notified if coverage lapses.
What should a cleaning company’s background check include?
At minimum, a criminal history check on every employee who enters your building, refreshed on a regular cycle rather than run once at hiring. Stronger programs add identity verification and reference checks. Ask what the check covers, who gets checked, and when it was last run.
How do I verify a hood cleaning company’s certification?
Ask which certification the technicians hold (IKECA is the most widely recognized) and ask to see a recent exhaust cleaning certificate showing the technician’s name and credential. After any hood service, a sticker on the hood should show the service date and the next one due. No certificate and no sticker means the work can’t be proven to your fire marshal or insurer.
How many references should I ask a cleaning company for?
Two or three is standard, and at least one should be a restaurant or other food service account. A company that hesitates to provide any references is showing you the answer.
Why are some kitchen cleaning quotes so much cheaper than others?
Labor and products dominate cleaning costs, so a quote far below market means less time on site, cheaper labor, weaker products, or tasks quietly dropped from the scope. Compare bids against the same written scope of work, and treat an outlier low price as a finding to investigate rather than a deal to grab.
