Lab-adjacent & Controlled Environment

Lab-adjacent, clean room, and controlled-environment cleaning through a vetted partner bench — only what we can deliver to spec, named on the COI.

Tech in cleanroom gowning wiping a stainless surface with lint-free wiper, air-shower visible behind, HEPA-filtered ceiling, no people in background.
Why this matters

What goes wrong when it's half-done.

Cleanroom cleaning is a different discipline from janitorial — gowning protocols, particle counts, IPA wipe technique, lint-free wipers, deionized water. Most janitorial vendors that say yes to cleanroom work are quietly delivering janitorial work in a cleanroom, which is how particle excursions happen. We deliver only what our vetted partner bench can deliver to spec — typically lab-adjacent and ISO 7 / ISO 8 controlled environments. ISO 5 and below, we'll refer.

How we run controlled env

Four operational principles, written into the route plan.

  1. Partner-bench delivery with named technicians, also on our COI

  2. Scope only as deep as we can credibly deliver — we don't oversell into ISO 5

  3. Documented gowning, chemistry, and HEPA protocols per cleanroom class

  4. Site-specific orientation and sign-off before the first shift

What's included

  • Lab-adjacent cleaning (offices, corridors, write-up rooms next to controlled space)
  • ISO 7 / ISO 8 controlled-environment cleaning where partner-bench coverage applies
  • Air-lock and gowning-room sanitation
  • Documented chemistry, dwell time, and gowning per visit
  • Coordination with your QA / EHS lead on protocol changes

What's not included

We name the line items we won't quietly run past you.

  • ISO 5 (Class 100) or below — referred to a specialty firm
  • GMP-regulated pharmaceutical manufacturing space (separate insurance and audit trail)
  • Vivarium or animal-research facilities (referred)
  • BSL-3 or BSL-4 biocontainment (referred)
What we use, and why

Specific tools. Documented chemistry. Operator credibility through specificity.

Equipment

  • Lint-free polyester wipers, IPA 70% in cleanroom-grade containers
  • HEPA-filtered cleanroom vacuums (no bagged, no exhaust to the room)
  • Deionized water for final wipes where particle spec requires it
  • Tacky mats at every air-lock entry, replaced on a logged cycle
  • Gowning protocol per cleanroom class — documented, trained, audited

When to add this to a recurring program

Cadence options we run for Controlled Env: Daily, Per-shift, Weekly, Project. We'll sequence it inside your existing program so the building doesn't see a second crew.

What you get back from us

Photo packet, escalation log, monthly report.

The artifact trail your auditor, your tenant, and your CFO can all read.

Photo packet by 9am

Date, address, scope completed, eight to twelve annotated photos, tech sign-off — emailed before you walk in.

Escalation log, <4hr response

Anything flagged on a visit gets logged and routed to a named lead. You see the open tickets, not the silence around them.

Monthly summary report

Photo-verified service, escalation log, scope adherence, consumables — one PDF, every site, every month.

What it costs

A real number after a 15-minute walk.

We bid controlled env from a walkthrough, not a square-footage table. Pricing reflects the building's risk profile, the crew tier, and the cadence. We'll quote a real number after a 15-minute site visit and never raise it mid-contract without 60 days written notice.

Annual review, written 60 days in advance, capped at CPI for renewals. No mid-contract surprises.

FAQ

Lab-adjacent & Controlled Environment, on a documented program.

Send us your scope and we'll send a real number back. Or book a 15-minute walkthrough — we bring a notepad and a camera, not a sales deck.

How Meridian operates

Crew model

Your recurring crew is W-2 Meridian, named in the contract. Specialty trade work — restoration, glass at height, regulated trades — flexes through a vetted partner bench, also named, also on our COI.

Insurance
$2M / $5M

General liability + umbrella. COI on file before day one, renewals tracked on our calendar.

Escalation
<4 hours

Named account manager, not a ticket queue. Re-clean or credit when something is wrong — your call.
