How to choose a commercial cleaning company

Choosing a commercial cleaner is unusual as a purchase. You will not be there when the work happens, the person who signs the contract is rarely the person who notices problems, and the thing you are buying is invisible when it goes well.

That combination rewards preparation more than negotiation.

Before you contact anybody

Spend twenty minutes on this and every conversation afterwards gets easier — and comparable.

1. 01

   Count your restrooms and your busy-day headcount

   Those two numbers predict cleaning frequency better than floor area does. Have them ready before you speak to anybody.

2. 02

   Walk the building and note what actually bothers you

   Usually there are two or three specific things. Entrance glass. A restroom that never feels right. A meeting room clients see. Those should shape the scope rather than being buried in a generic list.

3. 03

   Establish your access hours

   When can somebody actually be in the building, and what does that involve — keys, codes, alarms, building management sign-in? This constrains everything.

4. 04

   Decide the consumables question

   Will you stock restrooms and breakroom yourself, or do you want that supplied?

5. 05

   Write down what is definitely out of scope

   Kitchen equipment, IT gear, confidential paperwork, anything above a certain height. It is easier to state upfront than to argue about later.

What to verify

Five things, and they apply to any contractor regardless of size or brand. A well-run company answers all five without discomfort.

1. Insurance and bonding, with proof

Not “are you insured” but “can I see the certificate”. Somebody will be alone in your building out of hours around your equipment. This is a reasonable request and hesitation is informative.

2. Vetting, and when it happens

Ask how cleaners are background checked and at what point in their employment. A documented process applied before anyone enters a customer property is different from a check done eventually.

3. A written, banded scope

What happens every visit, weekly, monthly and quarterly. If a contractor cannot produce this, they are selling you an intention rather than a service. What is included in commercial cleaning sets out what a complete one looks like.

4. The exclusions

Ask directly what is not covered. A contractor who says “everything” is either not thinking or not being straight — regulated fields like commercial kitchen exhaust, clinical decontamination and biohazard remediation are outside general commercial cleaning, and a professional operator says so.

5. What happens when something is missed

A named contact, an expected response, and a guarantee with an actual timeframe. “We aim to satisfy” commits to nothing.

Comparing bids that are not quoting the same job

This is the core difficulty. Three quotes for one building will differ in scope, frequency banding, consumables and exclusions, and the headline number reflects all of that at once.

Line them up on a single sheet:

• Visits per week, and which days.
• Items in the every-visit band.
• Items in the weekly band.
• Whether a monthly band exists at all.
• Quarterly or periodic work included.
• Consumables: supplied, or reported only.
• Explicit exclusions.
• Response commitment when something is missed.

Once those are aligned, the prices become comparable. Frequently a bid that looked expensive is the only one with a monthly band in it.

Warning signs

None of these are disqualifying on their own. Two or more together are worth taking seriously.

• A scope described in one phrase. “Full janitorial” means nothing until it is itemised.
• Reluctance to provide insurance documentation. A two-minute request.
• A quote given without seeing the building or asking about restrooms. Somebody is guessing.
• Pressure to sign quickly. Cleaning contracts do not need to be signed today.
• No escalation route. If nothing describes what happens when something goes wrong, nothing will happen.
• Claiming to cover regulated specialisms. Kitchen exhaust and clinical decontamination need certification. A general cleaner claiming both is overselling.

The first ninety days

Most commercial cleaning relationships that fail were already failing in month one, and nobody raised it.

Walk the building in week two, in daylight, and check the specific things you noted before you hired anybody. Raise anything immediately rather than waiting for a review — a contractor who hears about a problem in week two fixes it; one who hears in month nine has been doing it wrong forty times.

Then schedule a proper review at ninety days. That is long enough for patterns to show and early enough to adjust frequency or scope before either side has settled into a habit that does not work.
