13 questions to ask a commercial cleaning company before you sign.

Visual inspection is not verification. The standard instrument for this in commercial cleaning is an ATP luminometer, which swabs a surface and returns a score in RLU (Relative Light Units) measuring organic residue left behind. Hospital cleaning audits commonly use a pass threshold in the 25-100 RLU range, with 25 being the tighter end; untested surfaces frequently read in the hundreds. Important limitation: an ATP score measures whether the cleaning step removed residue. It does not measure disinfection, does not detect a specific pathogen, and is not a compliance certification. A company that cannot produce any objective measurement is asking you to accept appearance as evidence.

Why it matters: It is the only question that separates a claim from a fact. Everything else a cleaning company tells you is downstream of whether they can measure anything at all.

Red flag answer: "Our team is very thorough" or "we do a walkthrough with the manager." Those are inspection processes, not measurements.

Our answer: We swab high-touch surfaces with an ATP luminometer and hold them below 25 RLU. If a surface reads high we re-clean and re-test on the spot, and you get the readings in writing.

A disinfectant only works if the surface stays visibly wet for the product's full label dwell time, commonly one to ten minutes depending on the product and the organism claim. Spraying and immediately wiping is the single most common failure in commercial cleaning, because it looks identical to a correct application and produces almost none of the effect. A qualified provider should be able to name the EPA registration number of the product they use in your space and state its dwell time without looking it up. They should also confirm they clean before they disinfect: disinfectant applied over organic soil is partly consumed neutralizing that soil instead of the target organism.

Why it matters: This is the fastest way to find out whether a crew has been trained in chemistry or just handed a bottle.

Red flag answer: Hesitation, or the phrase "hospital grade" with no product name and no number attached to it.

Our answer: EPA-registered products at full label dwell time, cleaning always performed before disinfection, and we will show you the label.

Cleaning is performed when the client is not present, which makes documentation the only record that the scoped work happened. A serious provider produces a room-by-room record after each visit, ideally with timestamped photographs, and can show you a redacted sample from an existing account. If the answer is that documentation is available on request or in the event of a complaint, then documentation is being treated as dispute protection rather than as part of the service.

Why it matters: In a regulated facility, your vendor's records become part of your own file when you are audited. An absence of records is your absence, not just theirs.

Red flag answer: "We can put that together if you need it." That means it does not currently exist.

Our answer: A room-by-room checklist and timestamped photos are delivered after every single visit, automatically. Ask us for a redacted sample and we will send one.

The standard controls are color-coded microfiber and equipment segregation: a specific color is assigned to restrooms, another to clinical or patient-contact surfaces, another to general areas, and cloths are never carried between zones. The related control is the two-bucket method, which separates clean solution from used solution so soil is not redistributed. A provider without a zoning system is very likely moving contamination from your restroom to your treatment surfaces, and neither of you would ever see it happen.

Why it matters: Cross-contamination is invisible. It never produces a complaint, which is exactly why it goes uncorrected for years.

Red flag answer: Any answer that describes changing cloths "when they get dirty" rather than by zone.

Our answer: Color-coded microfiber by zone, changed by room and not by appearance, plus documented SOPs per facility type.

Consistency of personnel is the strongest predictor of consistent cleaning quality, because most of what makes a good clean in a specific building is site knowledge rather than technique: which room is used for what, which surfaces are clinical, what is equipment and what is trash. Large rotating-crew models frequently show a noticeable quality decline around 90 days, once the crew that opened the account has been reassigned. Ask specifically whether the same named individuals are assigned to your account and what happens when one of them leaves.

Why it matters: A rotating crew has to relearn your building every few weeks, and each one cleans to a slightly different standard.

Red flag answer: "You'll always have a great team." That is not the same as the same team.

Our answer: The same trained, background-checked personnel stay assigned to your facility, starting with the owner. You will know exactly who is in your building.

This determines who carries liability, who controls training, and who is accountable when something goes wrong. It also affects turnover, which drives quality drift. Ask whether background checks are performed on every person who will enter your space, and ask to confirm it for the specific individuals assigned to your account rather than as a general company policy.

Why it matters: In a facility with patient records or controlled supplies, an unvetted person with after-hours access is a real exposure.

Red flag answer: A general policy statement that cannot be tied to the specific people entering your building.

Our answer: Background-checked, trained for your facility type, and assigned to your account rather than dispatched to it.

General janitorial training does not cover clinical environments. For dental and medical spaces the relevant items are OSHA bloodborne pathogen awareness, an understanding of the noncritical versus semicritical surface distinction, and HIPAA-discretion conduct, which means knowing not to read, move, or photograph anything with patient information on it. It is also worth clarifying the division of duties: certain clinical surface and instrument tasks belong to your own staff and should not be delegated to a cleaning contractor at all.

Why it matters: A crew trained on office buildings applies office standards to a treatment room, and nothing about the result looks wrong.

Red flag answer: "All of our staff are fully trained" with no named standard, certification, or curriculum behind it.

Our answer: OSHA bloodborne pathogen awareness training, IJCSA certification for medical cleaning practices, and scopes built per facility type.

Ask for a named person, a direct contact method, and a stated response window, in writing. In multi-layer or franchise structures the person you meet during the sale is often not the person managing your account afterward. The more useful version of this question is: who calls me when your team knows something went wrong, before I notice it? Proactive disclosure is a strong indicator of an internally accountable operation.

Why it matters: Missed work is inevitable. The difference between vendors is what happens in the hour after.

Red flag answer: A ticketing system with no named human attached to it.

Our answer: The owner answers the phone. If we miss something, you hear it from us first, with the correction already scheduled.

Every provider has absences. The question is whether the backup plan preserves the standard. Good answers describe a named, cross-trained backup who already knows your building, or a rescheduled visit with advance notice. Weaker answers describe pulling whoever is available that night, which reintroduces the unfamiliar-crew problem in the moment you are least likely to be watching.

Why it matters: This is where an otherwise consistent vendor quietly becomes an inconsistent one.

Red flag answer: "We always find coverage." Coverage is not the same as coverage that knows your operatory from your break room.

Our answer: You hear from us before the visit, and we reschedule rather than send someone who has not been trained on your facility. We do not send strangers.

Franchise models in commercial cleaning typically sell territories or routes to individual owners, with the parent company earning from royalties and territory sales. This can work well, but it means the entity you contracted with, the entity that manages the work, and the entity that owns the standard may be three different parties. Ask who has authority to change your scope or credit an invoice without escalating, and how far that decision has to travel.

Why it matters: Accountability tends to be strongest where ownership and delivery sit in the same person.

Red flag answer: An answer that requires three sentences to explain who actually holds your contract.

Our answer: Locally owned, Columbus-based, owner-led. Decisions are made here because there is nowhere else for them to be made.

Ask for the scope in writing at the room level rather than as a service tier name. Most disputes in commercial cleaning are scope disputes that both parties believed were settled. Pay particular attention to items commonly assumed but rarely specified: interior glass, baseboards, vents, high-touch electronics, refrigerator interiors, and the frequency attached to each. Frequency matters as much as inclusion; "detail cleaning" with no interval attached is not a commitment.

Why it matters: Nearly every complaint about a cleaning company traces back to an unwritten assumption.

Red flag answer: A one-page proposal with tier names and no room-level detail.

Our answer: Room-by-room scope in writing, with frequency attached to every line, built at the walkthrough.

Read the cancellation clause before the price. Look for the notice period, auto-renewal language, any early-termination fee, and whether an introductory rate escalates automatically after a set period. A provider confident in retention does not need to lock you in, and long lock-ins with automatic renewal are frequently a sign that the model expects quality to decline before the term ends.

Why it matters: The exit terms tell you what the vendor privately expects your satisfaction to be in month nine.

Red flag answer: Multi-year auto-renewal with a short cancellation window buried in the terms.

Our answer: Straightforward terms and no penalty trap. We would rather earn the next month than trap you in it.

Request a current certificate of insurance naming your business, and confirm both general liability and workers' compensation coverage. Without workers' compensation, an injury in your facility can become your exposure. This is a routine request that any established provider can fulfill within a day; difficulty producing a current certificate is itself informative.

Why it matters: It is the cheapest risk check available to you and takes one email.

Red flag answer: Any delay, or a certificate that has expired.

Our answer: Current certificates available on request, before you sign anything.
