Flowstar Cleanrooms

Flowstar Cleanrooms operates from Gilroy, California, serving the broader Silicon Valley region with specialized cleanroom design and installation services. Founded in 1990, this general contractor maintains a 23,000-square-foot manufacturing facility and currently holds a 3.4-star rating derived from five customer reviews. The company maintains standard weekday hours from 8 AM to 4 PM, with weekend operations closed.

This contractor distinguishes itself through an extensive portfolio of modular cleanroom solutions, including both hardwall and softwall configurations ranging from Class 100 to Class 10K environments. Their in-house capabilities encompass custom micro enclosures, horizontal and vertical laminar flow modules, air showers, gown changing rooms, and HEPA filter workstations. The facility produces stainless steel and Formica-top tables alongside environmental controlled chambers, offering complete turn-key installations with expedited delivery options for time-sensitive projects.

Customer experiences present a mixed picture. One reviewer recounted an urgent cleanroom repair that required prompt response, noting fair pricing alongside knowledgeable and professional service. A separate review described negative encounters involving scheduling delays and unexpected charges that were originally quoted as included. A third review referenced an unrelated traffic incident with a company representative, which did not relate to service quality.
