Can a janitorial company clean a lab? What it touches, and what it never does

Yes, for the building around the science: offices, corridors, restrooms, break rooms, the lobby, and whichever lab-floor zones your walkthrough map approves. No, for the science itself: benches, fume hoods, instruments, specimens, cleanrooms, gowning rooms, airlocks and every regulated waste stream. A janitorial company worth letting in writes that line down before the first visit.

The no-touch list, by kind of building

Every lab building holds two jobs: the facility, which a good janitorial crew can carry, and the controlled work, which belongs to your staff and specialists. We publish the line between them for four kinds of site:

• Research labs. Our research lab cleaning page covers “Lab floors and aisles cleaned only in the zones your walkthrough map approves” and fences off the rest: “Benches, fume hoods, instruments, and anything flagged active: strict no-touch, every visit”. It gives the reason in plain words: “One wiped-down bench can erase months of work”.
• Clinical labs and draw stations. The medical lab cleaning page takes “Lab-area floors and non-bench surfaces to your walkthrough spec — benches, instruments, specimens, sharps, and red-bag waste stay untouched”.
• Biotech, pharmaceutical and medical-device sites. The biotech company cleaning page lists “Controlled-material rooms, cleanrooms, and active lab benches: excluded and logged, visit after visit” and, on a device floor, “assembly benches under your quality system never touched”.
• Cleanroom buildings. The cleanroom support area cleaning page draws the firmest line of the four: “The controlled envelope, the gowning rooms, and the airlocks stay with your certified cleanroom-cleaning contractor”.

Read side by side, the four pages share one rule: what counts as active, controlled or classified is mapped at the walkthrough, not left to a crew’s judgment at night.

The gowning corridor, where “up to” matters

The approach to controlled space is where two of our pages draw the line in different places. In a biotech building, the biotech page covers “Gowning corridors and ante-areas on the non-classified side, cleaned to the walkthrough map”: the corridor can be on the route up to where your map says classified begins. In a building organized around a cleanroom, the cleanroom support page makes the door the line: “Support corridors cleaned with low-lint, low-particulate dust control up to — and never past — the gowning-room and airlock doors”.

Near the door, what changes is method, and the cleanroom support page explains why: “Particulate discipline does not start at the airlock: lint and dust generated in the support corridor migrate toward gowning, load your pre-filters, and ride in on the shoes and sleeves of everyone who gowns up.” When you walk that approach with any vendor, mark it in three states instead of two: cleaned normally, cleaned with low-lint methods, and never entered. A map with only “in” and “out” leaves the most sensitive stretch to someone’s judgment.

Waste: general trash only

Waste is where a lab’s line gets crossed by accident, because a bin looks like a bin. Our research lab page writes the rule into the scope: “General, non-hazardous trash only: chemical, biohazard, and sharps streams stay with your EHS-managed haulers under the documented waste protocol”.

Clinical labs get the most explicit answer, from the medical lab page: “Sharps, red-bag regulated waste, and specimen disposal stay with your team and your licensed medical-waste hauler. Our crews clean around those stations, never into them, and flag a full sharps container rather than touch it.” It also warns that “a lab should be suspicious of any cleaning vendor who says yes” to handling that waste, a test worth putting to every bidder, us included.

There’s a regulatory reason the stream stays with a specialist: the EPA says medical waste “is primarily regulated by state environmental and health departments” and that state programs differ significantly from one another. Settle at the walkthrough who receives the full-container flag, and how; a flag that waits in a voicemail until Monday is barely a flag.

A map the crew carries, a log you keep

A boundary only works if it holds on the fifth visit, not just at the walkthrough. The cleanroom support page describes how ours travels: “The walkthrough produces a written boundary map — room by room, door by door — and it goes to the crew before the first visit, in English and Spanish, with the same list your facilities team keeps.” The biotech page adds the record each visit leaves: “every excluded room is logged on each visit so your quality file shows it”.

The same cleanroom support page names the failure a map prevents, with a local example: “A Doral or Medley light-industrial building puts offices, warehouse, and controlled space under one roof, and a vendor that has to ask every night which door it may open is a vendor you end up escorting yourself.” The map exists so that nobody has to ask.

A map that works at night is mostly plain: rooms named the way their door signs name them, one agreed look for “flagged active” (a tag, a sign, a line on the sheet), and someone on your side who owns the changes. Our research lab page puts the changes in your hands: “the no-touch map is drawn together at the walkthrough, and your escort can adjust it visit by visit”.

Your access rules, your instrument schedule

In a lab building, access and timing are part of the boundary, not just logistics. Our research lab page publishes two commitments, “Escorted access honored in controlled areas, with your sign-in and badge rules followed on every visit” and “Evening, weekend, or agreed-window scheduling around instrument runs and experiments”, because, as the same page says, “cleaning windows have to be agreed with the lab manager, never assumed”. The biotech page says it in production terms: “escorted areas are cleaned escorted, and scheduling follows your production shifts”.

How the crew physically gets in (a key, a fob, a security desk, an escort) is its own question, answered in how cleaning crews access a building after hours. In a lab, add one line: the escort can take a room off the night’s route, no debate.

Five questions before any vendor badges in

Ask them in writing; each has a checkable answer:

1. Is the exclusion list in the written scope? And is each excluded room logged on every visit, or only promised?
2. Who holds the boundary map? And how does a change reach the crew before the next visit?
3. Who will actually be on the crew? Our cleanroom support page describes crews as “the same background-checked people week to week rather than a rotating pool”. People still move on, so ask how a newcomer is screened and briefed on your map; more in how commercial cleaning companies screen and train their crews.
4. Which products come through your door? Have them named in the scope so your EHS team can review the list before the first visit.
5. Is the vendor file ready? Ours, as the biotech page puts it: “You get the quote in writing, a COI within 2 business hours, $2M insured coverage, and no payment at booking.”

What we do, and what we won’t claim

What we do, in the words of our research lab page: “We clean the facility — floors, offices, corridors, restrooms, and common areas.” Lab-floor zones join that list only where your map puts them. What we won’t claim starts with a sentence from the cleanroom support page: “JAS is a general janitorial company and does not hold a cleanroom qualification, so we do not go near a door that needs one.” We claim no lab certification either, and we don’t handle, stage or haul any regulated waste stream from your lab.

Nor do we take over your compliance program: our research lab page leaves benches, hoods and instruments “with your lab staff under your chemical hygiene plan”. We make no promise about how an audit, a survey or an inspection turns out. This guide is general information, not regulatory advice: what your building requires is for your EHS officer and your regulators to say.
