What to Ask a Commercial Cleaning Company Before You Sign

Nine questions that get two cleaning quotes onto the same footing, on scope, staffing, insurance and who actually shows up.

The questions that matter are about people and scope, not price

Anybody comparing quotes for a San Antonio office ends up staring at numbers, and the numbers are the least informative part of the page. Two bids can be within a hair of each other and describe completely different jobs, because one priced restrooms nightly and the other priced them three times a week. The questions below are the ones that make two quotes actually comparable, and they are all things you can ask before you sign.

Commercial cleaning is on our service list and we are happy to quote, but the list below is written to help you buy well from whoever you pick. A provider who has not thought about staffing or scope will struggle with these questions, and that tells you something before you have signed anything.

1. Who is physically going to be in my building?

Start here. The company that signs the contract is not always the company that turns up. Subcontracting is common in commercial cleaning and it is not automatically bad, but it changes who trained the person with your keys and who is accountable when something is missed. Ask directly, and ask whether the same people come each time or whether it rotates.

2. Are those people background-checked?

Cleaners work after hours with access to desks, cash drawers, server rooms and whatever is left on a printer. It is an easy question to skip at the quoting stage and an awkward one to raise later. Our people are background-checked and performance reviewed, and it is the promise we would most want you to test, because it is the one you can verify by asking for the process rather than the phrase.

3. What exactly is in scope, and at what frequency?

Ask for the scope as a list with a frequency beside every line. Nightly, weekly, monthly, quarterly. Then read it for the things you assumed. Interior glass, baseboards, kitchen appliance exteriors, high dusting, floor care on hard surfaces and carpet all commonly sit at a lower frequency than clients picture. There is no correct answer here, only a documented one.

4. What is deliberately not included?

The better version of the last question. A provider who can tell you straight away what falls outside the contract has thought about the building. Carpet extraction, tile restoration and duct work are usually separate from a nightly service, and they should be. You want them named as separate so that nobody pretends they were folded in.

5. What does your insurance actually cover?

Fully insured is a phrase, not a document. Ask every company you are comparing for the certificate rather than the word, and read what is on it. What you want covered is damage to your property and a worker injured on your premises, and you want the dates current rather than expired last quarter. We are fully insured, and the question is worth putting to everybody on your list. The ones who get vague about paperwork are telling you something useful for free.

6. Who do I call when something is missed, and how fast do you reply?

Everybody misses something eventually. The difference between a good provider and a bad one is entirely in what happens next. Ask for a named contact and an expected response time, and ask what the fix looks like. A company that treats a missed restroom as a normal event to be corrected will be easier to work with than one that treats it as an accusation.

7. How do you handle turnover?

Cleaning has real turnover, and pretending otherwise helps nobody. What you want to know is what happens to your building when the regular person leaves. Is there documentation of your specific requirements, or does the knowledge walk out with them? It is one way a service that was excellent in month one drifts by month six.

8. Do you handle the specialist work, or do I need another vendor?

Carpet, tile and grout, upholstery, air ducts and post-construction cleanup all need different equipment from a nightly clean. Some providers subcontract every one of those, and there is nothing automatically wrong with that. What matters is whether you are told. Ask who turns up for the specialist work, ask whether one company stays accountable when something goes wrong, and get both answers before you sign rather than after.

9. How do we handle changes and how do we get out?

Buildings change and contracts should bend. Ask how a scope change is priced, how much notice a cancellation needs, and whether there is an initial term. None of this is adversarial. It is the part of the paperwork you will be glad you read the day you take another floor or lose one.

Where San Antonio buildings differ

Two local things belong on a walkthrough here. The water here is hard, and SAWS puts the typical hardness at 15 to 20 grains per gallon, so restroom fixtures, glass and tile pick up scale. Restroom detail and periodic tile and grout cleaning matter more here than a generic scope allows for. And fine limestone dust with seasonal cedar and oak pollen loads entrance carpet quickly, which is why entry matting and a plan for carpet cleaning are worth naming in the contract rather than leaving to chance.

Frequently asked questions

What is the single most important question to ask a commercial cleaner?

Who is actually going to be in my building. Everything else follows from the answer. If the crew is subcontracted, the company you signed with does not control the training, the vetting or the turnover, and you will be raising problems with somebody who has to pass them along. Either way, ask what vetting the people in your building have actually had, and ask before you sign rather than after.

Should a commercial cleaning contract list every task?

Yes, task by task and with a frequency against each one. Vague scope is the root of most disputes, because the client assumes something is nightly and the cleaner priced it monthly. Neither party is lying. Getting it written down before you sign prevents the conversation where somebody says this was always included.

How do I check a cleaning company is really insured?

Ask for the certificate and read what it covers and for how much. What you want to know is whether damage to your property and injury to a worker in your building are both covered, and whether the cover is current. A company that keeps it to hand will not hesitate.

Are background checks standard for commercial cleaning staff?

They are not universal, which is exactly why the question is worth asking. Your cleaners have keys, alarm codes and unsupervised access to desks and files after hours. We background check and performance review our people, and we would rather you ask us to prove it than take it on trust from a website.

How often should we review a commercial cleaning contract?

Walk the building with your provider after the first month, then quarterly. Buildings change. A team grows, a room becomes a kitchen, a lobby gets carpet. Reviewing on a schedule keeps the scope matched to the building instead of frozen at whatever was true the week you signed.
