What Clean Rooms West does
Hodess Cleanroom Construction, LLC, operating under brand references including Clean Rooms West, designs, builds, and installs modular cleanroom systems and critical-environment infrastructure — cleanrooms, dry rooms, and environmental rooms — for contamination- and climate-controlled operations. Founded in 1970 and headquartered in Attleboro, Massachusetts, the firm offers a full-lifecycle delivery model spanning program development, conceptual design and estimating, design and engineering, construction management, self-perform construction, and tool install, complemented by ongoing technical services including protocol management, critical cleaning, certification and testing, equipment service, and upgrades/repairs/retrofits. The product portfolio also includes two proprietary lines: the Hodess Labtech Series (developed in partnership with Labworks) and Hodess Ceiling Systems.
The company serves two primary vertical clusters: Life Sciences (Biotech, Healthcare, Pharmaceutical, Medical Device) and Advanced Manufacturing (Aerospace/Defense, Battery, Data Center, Semiconductor, Solar). Named customers include Boston Bio (pharmaceutical cleanroom, Milford, MA) and RoslinCT (biotechnology/cell therapy, Hopkinton, MA). Revenue is generated through quote-based project construction contracts (one-time license equivalent) and recurring technical services. Distribution is exclusively direct enterprise sales with no channel intermediaries, and projects of up to 2 million square feet have been delivered across multiple U.S. states and Canadian provinces.
Leadership is led by Steven Alley as President and owner. The firm is a privately held LLC with no disclosed institutional investors, parent company, or public cap table. It is recognized on ENR's Top 600 Specialty Contractors list. Operations span North America with offices across the region. The firm has been operating continuously for more than five decades and positions itself as a niche specialist rather than a generalist contractor, with self-perform construction capability supporting margin capture on larger engagements.
