Cleanroom, Data Center and Lab Cleaning in San Jose
Controlled-environment cleaning for cleanrooms, data halls and labs across San Jose, working inside your gowning, entry and escort rules from the very first visit.
Printable checklist
Silicon Valley’s controlled spaces
Much of San Jose’s tech work happens in rooms the public never sees. North San Jose holds semiconductor research labs, and South San Jose has large data center campuses.
Cleanrooms, data halls and labs share one rule: the room’s standard comes from the customer, and cleaning exists to protect it. Our controlled-environment cleaning works inside your rules, in plain steps your facility team can watch and check.
Gowning and entry
Crews gown at the entry in the order your gowning room posts, typically shoe covers or cleanroom boots, hood, mask, coverall and gloves. Carts, buckets and tools are wiped down before they cross the airlock, and anything that sheds stays outside the clean side.
Cleanroom classes are set under ISO 14644-1 by the airborne particle count each room allows, and semiconductor rooms often run at ISO 5 to ISO 7. Your room’s class and your facility’s procedures decide the frequencies, the materials and which bays the crew enters.
Top to bottom, cleanest to exit
Inside the room, work moves from top to bottom and from the cleanest zone toward the exit: ceilings, walls and light lenses first where your procedures include them, then equipment exteriors and work surfaces, with the floor always last.
Low-lint wipers and mop heads, charged with the solution your facility approves, are folded and turned so each pass uses a clean face. Floors are mopped in overlapping strokes back toward the door, and used materials leave the room bagged.
Data halls and raised floors
Data centers have their own priorities: keep dust off the floor, out of the cooling path and away from the racks. Cleaning covers raised-floor tile surfaces, hot and cold aisles, cage floors, door thresholds, and the staging and loading areas where dust arrives with deliveries. Rack doors and cabinet exteriors are wiped only where your team allows it.
Access works the data center’s way. Every visit is scheduled ahead, the crew signs in, shows ID and badges through security, and an escort accompanies them wherever your procedures call for one. Under-floor plenum cleaning runs when your facilities team opens the floor, with tiles lifted and replaced in the order they set.
Labs, R&D suites and the rooms around them
Research labs, QA rooms and R&D suites in North San Jose and across the city mix lab benches with offices, break rooms and restrooms. Benches and fume hoods stay with your lab staff until a surface is cleared for cleaning; the crew takes care of floors, approved sinks, ordinary trash that is not lab waste, and every surrounding room.
The rooms outside the controlled space matter too. Change rooms, corridors, offices and break rooms get regular janitorial service so dust never tracks toward the clean side, and nearby production floors can pair this work with industrial and warehouse cleaning.
Starting service in a controlled room
Before the first cleaning shift, your facility contact shows the crew the gowning room, the airlock order and the bays they may enter, and approves the wipers, mop heads and solutions that will go inside. Those materials are kept apart from general janitorial stock and labeled for the controlled space only.
Cleaning is then set around your production calendar rather than a fixed nightly slot. Rooms can be cleaned at shift change, during a tool changeover or across a planned shutdown week, when the deepest wall and ceiling work fits best. If a room’s procedure changes, your team tells the supervisor, and the next visit follows the new steps.
What sets the price for controlled-environment cleaning
Controlled-environment work is priced room by room. The factors are the number and size of rooms, the class of each cleanroom, how often each one is cleaned, gowning time per entry, the materials your facility specifies, escort and access steps, raised-floor and under-floor work, and whether visits fall on nights or weekends.
List your rooms and access rules in the quote form, and each space is priced on its own line so the total is easy to follow.
A few useful answers
Common questions
Do your cleaners follow our gowning procedure?
Yes. The crew gowns in the order your gowning room posts and wipes down every tool and cart before it crosses into the clean space.
Can you clean under raised floors in a data center?
Yes. Under-floor plenum cleaning is booked with your facilities team, and tiles are lifted and replaced in the order they set.
Will the crew work with our escort rules?
Yes. Visits are booked ahead, the crew signs in and badges through security, and an escort accompanies them wherever your procedures require one.
Do you clean ISO-classified cleanrooms?
Yes. Cleanrooms are cleaned at the frequency and with the materials your room class and facility procedures set, using low-lint wipers and a top-to-bottom sequence.
Do you clean the offices and break rooms around the lab?
Yes. Offices, corridors, change rooms, break rooms and restrooms around the controlled space are cleaned on a regular schedule.
