Controlled spaces across the South Bay’s biggest city
San Jose’s industrial parks hold labs, test floors and controlled rooms behind ordinary office facades, and the south of the city is home to large data center campuses.
Every one of those spaces depends on cleaning that respects the rules of the room. San Jose Commercial Cleaning Co plans each visit around your protocols, with background-checked cleaners who arrive knowing the procedure before they reach the door.
Gowning and entry, done your way
Controlled spaces start at the door. Our crews follow your gowning sequence exactly: the order for hoods, coveralls, boots, gloves and masks, the tacky mats and air showers, and the airlock or anteroom where garments go on. Nothing enters the room that your procedure does not allow.
Cleaning tools and supplies come in the same way. Carts, mop handles and buckets are wiped down before entry, and tools assigned to a cleanroom stay there instead of travelling between areas.
If your site uses sign-in logs, a written cleaning record or a supervisor check at the end of each visit, those steps become part of the routine.
Top to bottom, clean side to exit
Cleanroom cleaning follows gravity. The crew starts at the ceiling grid and the frames around filter units, works down the walls, pass-throughs and work surfaces, and finishes with the floor, so particles always move toward the area that is cleaned last.
Within each room, work runs from the cleanest zone toward the exit, with overlapping strokes and no backtracking across a finished surface. Low-lint wipes, cleanroom mops and the cleaning agents your site approves keep the job from adding the very particles it is meant to remove.
Your room’s ISO 14644-1 class, which grades air cleanliness by particle concentration, is your standard. The frequency, materials and steps of the cleaning plan are set to match the class your facility runs.
Data halls, raised floors and under-floor spaces
Data centers bring their own rules. Visits are booked in advance, every cleaner is badged or escorted as your security team directs, and the crew stays inside the cages, rows and rooms named in your access plan. Racks, cabling and equipment are never touched.
Raised floors collect dust that the cooling system will happily circulate. Floor tiles are lifted in sequence with your team’s approval, the under-floor space is vacuumed with filtered equipment, and the tiles go back exactly as they came out. Perforated tiles, the top surface of the floor and the areas around cooling units get cleaned in the same session.
Support rooms matter too. Loading docks, staging areas, battery and electrical rooms where access is approved, network operations centers, offices and break rooms all go into one plan.
Labs and R&D spaces
San Jose’s R&D buildings mix offices with electronics labs, test benches, wet labs and prototype rooms. Lab floors, sinks, door hardware and shared surfaces are cleaned on your schedule, while benches, instruments and chemical storage stay with your scientists and safety team.
Rooms with special handling are marked on the floor plan: where the crew cleans, where it does not enter, and which waste streams belong to your lab staff. Offices, restrooms and break rooms around the labs run on regular janitorial service, so the whole building stays on one plan.
Planned around uptime and production
Controlled spaces rarely stop for cleaning, so cleaning fits around them. Visits are set for shift changes, maintenance windows or planned shutdowns, and deeper under-floor or ceiling-level work is booked for the quiet weeks on your calendar.
Overnight and weekend crews keep the work clear of experiments, test runs and change windows.
When a schedule changes, a new tool goes in or a room is reclassified, tell us and the cleaning plan is updated before the next visit, so the crew always works from your current procedure.
What sets the price
Controlled-environment cleaning is quoted from your protocols rather than from a standard rate. The factors are the room class and gowning steps, total cleanroom and data hall area, how often each zone is cleaned, raised-floor and under-floor work, escort and access time, after-hours scheduling and the supporting offices and restrooms in the same building. A walkthrough with your facilities or EHS lead sets the plan and the written quote.
A few useful answers
Common questions.
Will your cleaners gown up exactly the way our procedure says?
Yes. Cleaners follow your gowning order, entry steps and garment rules on every visit, and tools for the cleanroom stay inside it.
Do you vacuum the space under our raised floor?
Yes. Tiles are lifted in sequence with your team’s approval, the under-floor space is vacuumed with filtered equipment, and every tile is returned to its place.
How does access work in a data center?
Your security team sets it: we book each visit ahead, and cleaners are badged or escorted and work only in approved rows and rooms.
Which cleanroom class do you clean to?
The class your room runs under ISO 14644-1. Cleaning steps, materials and frequency are set to match it, along with any written procedure your site keeps.
Can lab cleaning be combined with office cleaning in the same building?
Yes. Labs, data halls and the surrounding offices, restrooms and break rooms run on one plan, each area with its own steps and schedule.
