How do I choose a commercial cleaning company?

Commercial cleaning is a labour business. Roughly speaking, the majority of what you pay is wages and the on-costs attached to them, and there is very little fat in the remainder. That means a contractor cannot be meaningfully cheaper than another unless one of three things is true: they are more efficient, they are putting fewer hours on site, or they are not paying properly.

Genuine efficiency exists, but it moves the number by a modest amount. A quote that is dramatically lower than the others is almost always a scope difference in disguise, and the difference shows up in month three when the bathrooms are being serviced in half the time they need.

This is why the vetting process should establish the labour hours before the price. Once you know the hours each bidder is proposing, the prices become comparable and the decision becomes straightforward.

These five are pass or fail. A contractor who cannot produce them in a few days is a contractor who does not have them.

Ask for the documents themselves rather than for an assurance. A certificate of currency is a one-page document that any legitimate contractor can email within a day, and the currency dates should extend past the start of your contract term.

The award question is the one buyers most often skip and the one that predicts service stability best. A contractor who can name the instrument, the classification the site will be staffed at, and the hours the price is built on has priced the work properly. One who deflects has not.

These four separate contractors who have thought about your building from contractors who have sent you a template.

The staffing model is the strongest single predictor of whether you will be satisfied. A dedicated cleaner or a stable small team that returns each visit learns the building, notices what has changed and takes ownership of the standard. A rotating pool of unfamiliar staff cannot, no matter how well managed.

The labour hours figure is the second. Ask directly: how many cleaner hours per attendance is this price built on, and how are those hours distributed across the building. A contractor who answers precisely has estimated the work. One who cannot is guessing, and the guess will be corrected later at your expense or at your standard.

Every contractor claims to care about quality. The three points here distinguish the ones who have a system from the ones who have an intention.

A documented audit regime means somebody inspects on a stated interval against a stated scoring sheet, and the score is recorded and shared with you. Ask to see a blank audit sheet. If one exists, it will arrive immediately. If it does not, that tells you what you need to know.

References are worth more than any marketing claim, but only if they are comparable and contactable. Two references from buildings genuinely like yours, with permission already obtained so the calls get answered, are worth more than a page of logos. When you call, ask what went wrong at some point and how it was handled, because every contract has a problem at some point and the answer tells you how the next one will go.

Be sceptical of unverifiable numbers. A star rating or a satisfaction percentage that cannot be traced to a source is a marketing decoration, not evidence. So is a guarantee that does not appear in the contract. If a promise matters to you, it belongs in the written agreement.

The last three points are about what happens after the honeymoon, and they are the ones businesses regret skipping.

Inclusions and exclusions decide whether the price you agreed is the price you pay. Consumables are the most common surprise, followed by periodic tasks that turn out to be add-ons. Get both in writing, with the periodic tasks listed by interval and by price.

Contract and notice terms decide whether you can act if the service declines. A month-to-month arrangement with a short written notice period keeps the contractor accountable in a way a three-year term does not. Pro Clean Corp operates month to month with 30 days written notice. Whatever you agree, read the rollover clause and confirm the exit process, including the return of keys and access credentials.

An agreed variation rate is the small clause that saves the most friction. When a one-off requirement comes up, and it always does, a pre-agreed hourly rate turns a negotiation into an instruction.

Some signals are strong enough that no price makes up for them. If two or more of these appear, the contract will consume more of your time than it saves.

The most reliable warning is a quote produced without anyone visiting the building. Cleaning cost is driven by condition, layout, wet area count and access, none of which are visible from an address. A price given over the phone is a price that will be revised.

The second is pressure. A contractor pushing for a signature before you have had time to compare, or offering a discount that expires this week, is managing your decision process rather than your building.

Put the fifteen points in a spreadsheet with one column per bidder and fill it in from the written responses. This takes an hour and it makes the decision almost mechanical.

Compare the labour hours first, before you look at the prices. If one bidder is proposing meaningfully fewer hours for the same scope, either they have a genuine efficiency they can explain or they have under-scoped. Ask them directly and judge the answer.

Then compare the prices against the hours. Pro Clean Corp publishes indicative bands of $35 to $50 per hour for general commercial and office work, $45 to $65 per hour for warehouse and industrial, and $55 to $75 per hour for specialist and medical, with ongoing contract work at $30 to $45 per hour and one-off work at $40 to $50 per hour. A bid implying an effective rate well below the applicable band is telling you something about the hours or about the wages.

Finally, weigh the qualitative evidence: the references, the audit system, the staffing model and whether the person you dealt with actually understood your building. Those factors decide whether you are still satisfied in month twelve, which is the only measure that matters.
