Built for facilities where trust is the spec.
If your building already limits who gets access at all, this is the cleaning program built for it.
Financial & trading firms
Confidential floors and after-hours discretion — we schedule around trading hours and keep crews in-lane to assigned zones.
Data centers & secure records storage
Controlled-access, chain-of-custody environments — documented entry and exit, no wandering; we clean the space, not the contents.
Semiconductor, photonics & cleanrooms
Contamination-controlled environments cleaned to your cleanroom protocols and classification — gowning, approved products.
Life-sciences, laboratory & isotope facilities
Regulated, compliance-sensitive spaces — we follow your lab, PPE and handling rules, and stay out of controlled zones unless cleared.
Clearance-sensitive & high-security sites
Escorted access and vetting to your requirements — badges, sign-in, restricted areas, every visit documented.
Government & regulated offices
Public-sector and regulated workplaces with strict access and confidentiality rules — cleaned to your protocols.
The capability stack behind the service.
Background-checked, vetted crews
Every technician is screened and background-checked before they're assigned — security starts at hiring.
NDAs signed, confidentiality by default
We sign NDAs on request and back every engagement with a confidentiality agreement.
Documented logs, photos where it counts
Every visit is clocked in and out and every task logged in your own private client portal, with photos where it counts — never public, never shared.
Cleanroom-capable
Controlled-environment and cleanroom cleaning to your classification — your protocols, not an ISO claim.
$5M insured, CNESST-compliant
$5M liability, fully insured crews, CNESST-compliant. Proof of insurance on request before you sign.
Escorted & after-hours
We work escorted where required and around your operating or trading hours — your access windows, not ours.
Why standard cleaners can't do this.
A sensitive facility isn't a harder version of a normal clean — it's a different job, and most vendors aren't equipped for it.
Not built for it
- Crews hired fast, rarely background-checked
- No NDA — or one they can't enforce
- No proof of what was done, or by whom
- No private record — it's in their inbox
- No cleanroom or controlled-environment capability
- Thin or unclear insurance

- Background-checked, screened technicians
- NDAs signed on request
- Documented logs, every visit, photos where it counts
- A private client portal only you can see

- $5M liability, CNESST-compliant, fully insured
How a secure engagement works.
Vetting & background checks
Every technician is screened and background-checked before they're assigned to your site.
Confidentiality agreement
We sign an NDA on request and back every engagement with a confidentiality agreement.
Walkthrough & zone mapping
On-site, we map your no-photo and no-touch zones and your access rules before a single visit.
Access protocol set
Badges, keys or escort — we set the access method to your security requirements and log it.
Documented service
Each visit is completed to a checklist and clocked in and out in your own private portal, with photos where it counts.
Inspection & issue resolution
Scored inspections, and any flagged issue logged, assigned and closed with proof.
Trust is the deliverable. We back it with vetted people, signed agreements, documented photo-proof in a private portal, cleanroom capability and $5M insurance — a security posture most cleaning companies simply can't match.
