Cleanroom, Data Center and Lab Cleaning in San Ramon
Controlled-environment cleaning for San Ramon R&D labs, cleanrooms and server rooms, with gowning, low-lint materials and a ceiling-down sequence that follows the protocol your facility runs.

Research and technology space behind office facades
San Ramon is better known for office towers than for labs, yet controlled rooms are spread through its business parks. R&D suites, labs and server rooms sit behind ordinary office fronts there.
A lab suite can share a hallway with conference rooms, and a server room can sit behind a plain door next to a break room. We clean both sides under one plan, with a separate written procedure for each controlled room so nothing from the office side follows the crew inside.
Gowning at the door, by your rules
Every controlled room starts at its gowning area. Our cleaners put on your garments in your posted order, typically hair cover, face mask, coverall, boots and gloves, and cross the tacky mats the way your own staff do. If your SOP calls for a second pair of gloves or a sleeve change between rooms, that step goes into our procedure too.
Equipment is staged the same way. Cleanroom mops, buckets and wipes are wiped down before they cross the line, and tools assigned to a room stay with that room. Cardboard, paper towels and anything that sheds stay outside. Spent wipes and garments leave through the exit path your facility specifies.
Ceilings and walls first, floors last
Particles fall, so cleaning moves downward. Ceiling panels, light lenses and return grilles come first, then walls, pass-through chambers and doors, then benches and carts, and the floor finishes the visit. Each surface is wiped with overlapping strokes in one direction rather than circles, which pushes particles off the surface instead of spreading them around.
Inside the room, the crew works from the far wall back toward the exit, so nobody walks across a freshly cleaned floor. Low-lint polyester wipes, presaturated wipes where your QA team prefers them, and cleanroom mops with a multi-bucket system keep used solution away from clean solution. The cleaning agents themselves are the ones your quality group approves.
Your facility’s classification under ISO 14644-1 sets the standard the room must hold, and your environmental monitoring shows whether it is holding. We match the frequency and detail of each visit to that standard and adjust when your data calls for it.
Lab benches, fume hoods and the rooms around them
Research labs mix controlled zones with ordinary support space. Floors, sinks, door hardware, casework fronts and the outer faces of fume hoods and biosafety cabinets are cleaned on each visit. Lab staff clear and release bench tops, and our crew cleans the surfaces they release, leaving samples, reagents and instruments exactly where they sit.
Around the labs sit the rooms that keep a research team running: glass wash, storage rooms, write-up desks, conference rooms, locker rooms and restrooms. Those follow our office cleaning routine on the same visit, which keeps one schedule and one point of contact for the whole suite.
Server rooms, raised floors and escorted access
Data rooms run on access control. Our cleaners work inside the windows your IT or facilities team sets, sign the visitor log, carry the badges you issue and stay with their escort for the full visit. No cabinet is opened and no cable is moved; the crew works around racks, never inside them.
Dust is the enemy in a server room because it clogs filters and settles on hot components. Floors and cabinet exteriors are cleaned with HEPA-filtered vacuums and dry or barely damp low-lint cloths, and nothing wet goes near powered equipment. Hard floors outside the white space get the floor care that suits their finish, including static-dissipative finishes your facility specifies.
Raised floors need a careful hand. With your team watching, a few tiles at a time are lifted with a tile puller, the plenum and cable trays are vacuumed, and each section is closed before the next one opens, so airflow under the floor barely changes.
What shapes pricing for controlled spaces
Controlled rooms take more time per square foot than offices, and the factors are easy to list. Room classification and visit frequency set the base. Gowning time adds to every entry, and a suite with several gowning points costs more than one large room behind a single door.
Raised floor area and plenum depth, the escort windows your IT team can offer, after-hours or weekend timing and whether you supply garments and wipes shape the rest. We walk the rooms with your facilities lead, review your SOPs and then send a written quote.
A few useful answers
Common questions
Whose gowning procedure does your crew follow?
Yours. Our cleaners gown in your gowning area with your garments, in the order your SOP posts, and they repeat any change steps your procedure requires between rooms.
Can under-floor cleaning happen while our servers stay online?
Yes. Tiles are lifted a few at a time with your team present, the plenum is vacuumed with HEPA-filtered equipment, and each opening is closed before the next tile comes up.
Which materials does the crew bring into a controlled room?
Low-lint polyester wipes, cleanroom mops, buckets assigned to that room and the cleaning agents your quality group approves. Nothing that sheds, such as cardboard or paper towels, crosses the gowning line.
How is our ISO 14644 classification reflected in the cleaning plan?
Your classification sets the standard the room must hold, and your monitoring results show how it is holding. We set visit frequency and detail to match both and adjust when the data changes.
Can lab cleaning wait until researchers have gone home?
Yes. We book lab visits for after the last researcher leaves or for Saturday and Sunday, once staff have cleared and released their benches.
