Buyer's guide · Vetting a cleaner

How to vet a cleaner for a secure facility.

Q: How do I vet a commercial cleaner for a secure facility?

Screen on trust, not price. Ask for eight things: a signed NDA covering the company and the individual cleaners; background-checked staff; a named, low-turnover crew; access-control and escort protocols with documented entry and exit; a documented record of every visit in a private portal, with photos where it counts; $5M liability and CNESST compliance with proof before you sign; references by category; and any specialty capability you need, such as cleaning to your cleanroom classification. A vendor who can't produce these on request isn't ready for a sensitive site.

Q: What insurance should a commercial cleaner carry?

Ask for proof of general liability (we carry $5M) and confirmation they are CNESST-compliant with fully insured crews, in Québec. Get the certificate before you sign, not after an incident. Thin or vague insurance is a red flag on any site, and disqualifying on a sensitive one.

Q: How can I verify a cleaner actually did the work?

Demand proof, not promises. We photo-verify every task on a checklist each visit, with the time and an inspection score, in your own private client portal. You can see a sample portal before you sign. If a vendor can only offer "trust us," you have no way to audit a site you can't watch overnight.

Q: Does staff turnover matter when vetting a cleaner?

A great deal. A named, stable crew that knows your rules is far safer than a nightly rotation of unfamiliar faces. Ask who will actually be on your site and how often that changes — low turnover means fewer people vetted-and-cleared, and fewer chances for a mistake.

A practical checklist you can act on — the questions to ask, the proof to demand, and the red flags that should end the conversation.

The short version

To vet a commercial cleaner for a secure or high-security facility, screen on trust, not price. The eight things that matter: (1) a signed NDA covering both the company and the individual cleaners; (2) background-checked, screened staff; (3) a named, low-turnover crew — not a rotating cast; (4) access-control and escort protocols with documented entry and exit; (5) a documented record of every visit in a private portal, with photos where it counts; (6) $5M liability and CNESST compliance, with proof before you sign; (7) references by category — they should decline to name confidential clients, and that's a good sign; and (8) any specialized capability you need, like cleaning to your cleanroom classification.

A cleaner who can't produce these on request isn't ready for a sensitive site.

Print this

The 8-point vetting checklist.

Work down the list. Each item is something a serious vendor can prove on request — and a risky one can't.

A signed NDA — company and staff

Confidentiality on paper, binding both the company and the assigned cleaners. See how cleaning NDAs work.

Background-checked crews

Every technician screened before they set foot in your facility. Ask when and how they vet — before assignment, not after.

A named, low-turnover crew

Ask who will actually be on your site and how often it changes. A stable, cleared crew beats a nightly rotation of strangers.

Access control & escort protocol

Keys and badges logged to named staff, returned on schedule, escorted where required, with entry and exit documented every visit.

Documented accountability

Proof of every visit — task checklist, time and inspection score — in a private portal. See a sample. "Trust us" is not proof.

Insurance & CNESST compliance

Proof of liability coverage (we carry $5M) and CNESST compliance, in hand before you sign — not after an incident.

References by category

They should give references by industry — "a records-storage site" — and decline to name confidential clients. That discretion is the point.

Specialty capability you need

Cleanroom, data-center or lab work? Confirm they clean to your protocols and classification — not an ISO claim they don't hold.

Know the signals

Red flags vs. green flags.

You can learn most of what you need in one conversation — if you know what to listen for.

Walk away

Red flags

A rotating, anonymous crew — different faces every week
Won't sign an NDA, or "we've never been asked"
No background checks, or can't say when they run them
No proof of insurance, or vague coverage
No record of who had access, or when
Names their confidential clients to impress you
A price far below everyone else

Worth a walkthrough

Green flags

Named, stable crew assigned to your site
Signs your NDA — company and staff — without hesitation
Background-checked before anyone is assigned
$5M liability + CNESST proof offered up front
Documented access — keys and badges logged in and out
References by category, discreet about who they serve
Priced on scope and risk, and can prove the work

The process

How to run the vetting.

Shortlist on trust

Screen candidates against the 8-point checklist before price ever comes up. Anyone who fails the trust items is off the list.

Request proof

Ask for the NDA, the insurance certificate, the background-check policy and a sample of their service reporting — in writing, before the walkthrough.

Walk the site together

See how they think about your no-go zones, access and escort rules. A serious vendor asks security questions you didn't prompt.

Run a short trial

Start with a defined trial period and watch the proof come in. It's the cheapest way to test a vendor before handing over full access.

Document the standard

Put the access, confidentiality and reporting expectations in the contract, so the standard survives staff changes on both sides.

Re-check periodically

Confirm insurance stays current and the crew stays the crew. Vetting once at signing isn't the same as staying vetted.

Where we fit

We're built to pass this checklist.

Our whole system is the buyer's screening checklist made real — background-checked crews, NDAs signed on request, $5M liability, CNESST compliance, visit logs and photos in a private client portal, and the discretion to never turn you into a name we didn't clear. It's why financial firms, secure records and data-storage sites, advanced-electronics plants and laboratories across Montreal let us through doors most vendors never get past.

You ask, we answer

Vetting a cleaner, answered.

How do I vet a commercial cleaner for a secure facility?

Screen on trust, not price. Ask for eight things: a signed NDA covering the company and the individual cleaners; background-checked staff; a named, low-turnover crew; access-control and escort protocols with documented entry and exit; a documented record of every visit in a private portal, with photos where it counts; $5M liability and CNESST compliance with proof before you sign; references by category; and any specialty capability you need, such as cleaning to your cleanroom classification. A vendor who can't produce these on request isn't ready for a sensitive site.

What questions should I ask a cleaning company for a high-security site?

"Will you sign our NDA — company and staff?" "Are your cleaners background-checked?" "Who exactly will be on my site, and how often does that change?" "How do you handle keys, badges and escorted access?" "Can I see proof of what was done each visit?" "What is your liability coverage and are you CNESST-compliant?" "Can you give references in my industry without naming confidential clients?" The quality of the answers tells you more than the price.

Should a cleaning company be willing to name its confidential clients?

No — and if they rattle off sensitive client names to win your business, assume they'll do the same with yours. For trust-critical work, the refusal to name clients is a good sign. A trustworthy vendor gives references by category ("a data-storage facility", "a trading firm") and only names a client with that client's explicit permission.

Why do background checks matter more than price for a secure facility?

Because the risk you're managing isn't the cost of cleaning — it's the cost of the wrong person having after-hours, often unescorted access to your floor. A breach, a leak or a theft dwarfs any invoice. Background-checked, screened crews are the single most important control, which is why we vet before anyone is assigned to a site.

What insurance should a commercial cleaner carry?

Ask for proof of general liability (we carry $5M) and confirmation they are CNESST-compliant with fully insured crews, in Québec. Get the certificate before you sign, not after an incident. Thin or vague insurance is a red flag on any site, and disqualifying on a sensitive one.

How can I verify a cleaner actually did the work?

Demand proof, not promises. We photo-verify every task on a checklist each visit, with the time and an inspection score, in your own private client portal. You can see a sample portal before you sign. If a vendor can only offer "trust us," you have no way to audit a site you can't watch overnight.

What are the red flags when hiring a cleaner for a sensitive site?

A rotating, anonymous crew; no willingness to sign an NDA; no background checks; no proof of insurance; no record of who had access or when; price far below everyone else; and a readiness to name their confidential clients. Any one of these should slow you down; two or more should end the conversation.

How do you control access — keys, badges and escorts?

To your protocol. We log every key, badge and credential issued to us, assign them to named staff, and return or deactivate them on schedule. We work escorted wherever your security requires it, and entry and exit are documented on every visit.

Does staff turnover matter when vetting a cleaner?

A great deal. A named, stable crew that knows your rules is far safer than a nightly rotation of unfamiliar faces. Ask who will actually be on your site and how often that changes — low turnover means fewer people vetted-and-cleared, and fewer chances for a mistake.

Can a regular office cleaner handle a cleanroom or data center?

Usually not without specific capability. Controlled environments need particulate and static discipline, gowning, approved products and documentation — see our data-center & cleanroom requirements guide. Confirm the vendor can clean to your protocols and classification (never an ISO claim they don't hold) before you assume they can.

How long should vetting a cleaner take?

Plan for a shortlist, a proof request, an on-site walkthrough, and often a short trial period before a full contract. Rushing it is how the wrong vendor gets keys to a sensitive building. A serious cleaner will welcome the scrutiny — it's the same standard they hold themselves to.

Do you serve secure and high-security facilities in Montreal?

Yes. We clean trust-critical facilities across Greater Montreal — financial and trading firms, secure records and data storage, semiconductor and advanced-electronics sites, life-sciences and laboratory facilities, and clearance-sensitive sites. See our secure facility cleaning page or request a walkthrough.
