Where a stray fiber counts
In an ordinary office, a little dust on a shelf is a cosmetic problem. In a cleanroom, a server room or a research lab, the same dust can ruin a sample, settle on an optic or get pulled into cooling equipment. Cleaning these rooms is less about elbow grease and more about discipline: approved materials, a fixed order of work and the same steps on every visit.
Your written procedures are the starting point. On a free walkthrough your lab manager, quality lead or data center operator shows us each controlled room, the gowning area, the approved product list and any equipment that stays hands-off. We turn that into a room-by-room cleaning procedure, and our background-checked cleaners follow it on every visit.
Gowning in before the first wipe
Entry to a controlled room follows your posted sequence. Cleaners put on the coveralls, hoods, masks, gloves and shoe covers your facility issues, in the order shown at the gowning station, and leave phones, paper and street jackets in the anteroom. Gowns come off in reverse on the way out, exactly as your own staff do it.
Equipment gets the same treatment. Mops, buckets, wiper stock and spray bottles used in controlled rooms are dedicated to those rooms, stored apart from general supplies and wiped down before they pass the airlock. Nothing that touched a lobby floor or an office restroom ever goes past the gowning line.
Ceiling to floor, cleanest end to the door
Work runs from the top of the room down: ceiling panels and light lenses in reach, then walls and windows, then pass-through chambers, benches and equipment exteriors, and the floor last. Within each level, the crew moves from the cleanest end of the room toward the exit, so particles always travel toward surfaces still waiting their turn.
Low-lint, low-particle wipers replace ordinary cloths, mop heads are cleanroom grade, and solutions are mixed to the dilutions your quality team approves. Where your rooms are classified under ISO 14644-1, the class your facility holds and your own procedures set the frequency and method, and the crew works to them as written.
Server rooms, data halls and raised floors
Oakland’s network rooms range from downtown colocation space to telecom closets and server rooms inside office buildings. Those spaces stay healthier with regular dust control, because particles drawn into server intakes and cooling units add up quietly over months.
Raised-floor surfaces are vacuumed with HEPA-filtered equipment and damp-wiped with low-lint material, and the under-floor space can be cleaned section by section while your staff lift and reseat the tiles. Rack exteriors, door frames, cable trays within reach and cooling unit grilles are dusted without touching anything inside the cabinets.
Access stays under your control. Badge checks, sign-in logs, escorts, camera rules and cage boundaries are followed on every visit, and cleaning is scheduled into the maintenance windows your operations team prefers.
Teaching, testing and research labs in Oakland
Teaching labs, testing labs and life sciences research space each bring their own rules and schedules.
Lab cleaning covers floors, sinks, glass partitions, door hardware, fume hood and cabinet exteriors and general waste collection. Benches with active work, labeled samples and instruments are left just as your staff arranged them, and the clear surfaces around them are cleaned. Anything that needs special handling stays with your lab team.
The offices that surround the controlled rooms
Every controlled space sits inside a working building. Offices, conference rooms, break rooms, locker rooms, restrooms and loading areas get our recurring janitorial care on the same schedule, using a separate set of tools that never enters the cleanroom or the data hall.
One plan can cover the whole property. Visitors find a tidy lobby and staff return to clean offices, while each lab or server room keeps its own procedure. Corridors and support areas with hard floors can add scrubbing and finish work through our commercial floor care service.
What goes into the quote
Controlled-environment cleaning is quoted after a walkthrough, since no two facilities share the same procedures. The main factors are the number and size of controlled rooms, their classification, gowning time at each entry, visit frequency, raised-floor and under-floor work, escort and access windows and the ratio of controlled space to ordinary offices.
Labs and data halls are often cleaned at night or on weekends, and the schedule follows yours. The quote lists the controlled rooms and the surrounding offices on separate lines, so it is clear where the time goes. Send us your procedures, walk the rooms with us and we return a written quote.
A few useful answers
Common questions.
Do your cleaners bring their own gowns?
No. They wear the garments your facility issues and put them on in the order posted at your gowning station, so every entry matches your procedure.
Who decides how often each controlled room is cleaned?
Your facility does. The room class and your written procedures set the frequency, and visits are scheduled to match them.
Can you clean our server room without touching the equipment?
Yes. Floors, rack exteriors, door frames and cooling unit grilles are cleaned, and nothing inside a cabinet or cage is handled.
Can the offices and the lab be cleaned on one schedule?
Yes. One plan covers both, with separate tools for the controlled rooms and the general offices, and both appear as lines on one quote.
What happens to benches with experiments in progress?
They are left exactly as your staff set them. Cleaners work on the floor, sinks and open surfaces around them.
