Cleanroom and Laboratory Cleaning
Cleanroom and laboratory cleaning for San Mateo facilities
We clean San Mateo laboratories and cleanrooms in the order, and with the products, your facility team sets, usually in the evening or overnight once research winds down. Offices and breakrooms in the same building can share the plan.
Cleanrooms and transition spaces
Cleaning covers the room surfaces you specify, gowning areas, and transition zones. Entry and gowning procedures follow the facility’s requirements for each space.
In the lab, we clean the bench surfaces and equipment exteriors your team lists.
Controlled rooms are cleaned once your team confirms they are safe to enter, and the offices, staff rooms and corridors nearby get their own routine on the same visit.
Peninsula life-science buildings mix labs, cleanrooms and offices. Controlled areas follow your procedures while offices get standard care, all on one coordinated plan.
Offices and breakrooms nearby
Write-up offices, breakrooms and corridors sit a few steps from the controlled rooms in most lab buildings.
Neighboring offices and breakrooms receive standard care through office cleaning, and campuses in Foster City can pair the two. Coordinating both keeps the controlled rooms and the workplace on one schedule.
What the facility provides before cleaning starts
Controlled-room cleaning is only as precise as the instructions behind it. Before the first visit, the facility shares the products and tools allowed in each room, the order in which rooms are entered, the gowning steps at each transition and the operating conditions that must be met before cleaners go in. Those instructions become the routine for every visit that follows.
Your team handles instruments and samples; we clean the surfaces around them.
Laboratory floors and surrounding rooms
Laboratory floors follow the facility’s direction on products and method, not a general office routine. Corridors and break areas outside the controlled zone receive standard hard-floor care, with periodic finish work arranged through floor care when those floors show wear.
Keeping the two routines distinct matters on the Peninsula, where a single building in Foster City or San Mateo holds write-up offices, a breakroom and a suite of controlled rooms on one floor. Each area stays on its own task list, and the room sequence the facility sets decides where the crew begins and where it finishes.
Scheduling around research activity
Controlled rooms are cleaned when the operating state allows safe entry, which often means evening, overnight or weekend hours. Booking the visit for those windows keeps cleaning away from active experiments and returns rooms to staff ready for the next run.
Frequency follows the facility’s own requirements for each room. Gowning areas and transition zones that see traffic every shift belong on each visit, while rooms used occasionally follow a lighter rotation the facility chooses. Write-up offices and breakrooms nearby keep their own schedule through recurring janitorial services.
What cleanroom and laboratory cleaning costs next to office space
Laboratories and controlled rooms cost more to clean than office floors. Published 2026 market rates put lab space in San Mateo at about $0.19 to $0.38 per square foot a month, against $0.16 to $0.25 for offices on a five-night schedule. Gowning and entry steps, the facility’s own products and procedures, and slower, more careful work around benches and equipment exteriors explain the difference.
A Foster City life science building with 6,000 square feet of offices and 3,000 square feet of laboratory and transition space shows how the two rates combine. The office side at $0.19 comes to $1,140 a month, and the lab side at $0.30 adds $900, for a total near $2,040. Stricter gowning in higher-grade cleanrooms, more frequent visits during research activity, and night or weekend timing around experiments move the lab figure toward the top of its range. We walk each room with your facility team before quoting, and the cost guide compares the bands for every service.
A few useful answers
Questions about controlled-room cleaning
Can gowning and transition areas receive cleaning?
Yes. Gowning rooms and transition zones are cleaned every visit, following your gowning steps.
Can lab buildings get office cleaning too?
Yes. Offices and labs can be covered on one coordinated plan.
What happens when one of our room procedures changes?
Send us the revised procedure. The crew follows the new version from the next visit, and the old one is retired so nobody works from two copies.
Can deeper cleaning be planned around a shutdown?
Yes. A planned shutdown or equipment changeover opens time for work that busy rooms cannot get the rest of the year, and we schedule it around your dates.
Is cleanroom janitorial work done after hours?
Yes. Visits run in the evening, overnight or on weekends, whenever the room’s operating state allows safe access.
