Contamination control is not ordinary cleaning — it requires precision, discipline, and specialized training. Pacific Building's cleanroom division provides the protocols, trained technicians, and meticulous procedures that semiconductor fabrication plants, biotech laboratories, and technology facilities require. One particle out of spec can cost millions. Our teams understand that.

Quality & Safety Standards

Our cleanroom cleaning program follows industry-standard protocols covering a range of cleanroom classifications. Every technician completes training in gowning procedures, anti-static protocols, particle count verification, and chemical compatibility for sensitive equipment surfaces. We maintain detailed logs of all cleaning activities, chemical applications, and particle count measurements for your quality records.
