About Guy L Warden & Sons
Guy L Warden & Sons, doing business as Warden, is a minority-owned, Asian-Pacific American-owned for-profit Subchapter S corporation based in Cerritos, California, that operates exclusively as a prime contractor providing mechanical infrastructure installation, maintenance, repair, and upgrade services to federal healthcare and correctional facilities. The company competes on full-and-open federal contracts with no set-aside posture, though individual purchase orders occasionally carry total small business designations.
Warden's capability portfolio centers on steam, hot water, heating, ventilation, air-conditioning (HVAC), and condensate systems at Department of Veterans Affairs medical facilities. Representative work includes a $750 thousand emergency steam system preventive maintenance and upgrade contract at the VA Medical Center in Loma Linda, California (awarded December 2025, ultimate completion December 2026); a $325.4 thousand replacement of a hot water unit and water mixing distribution station at a VA facility in Long Beach, California (July 2021); a $319.4 thousand emergency hot water return system contract with VISN 22 (August 2021); and a $187.5 thousand first-floor mechanical room piping upgrade at VA Loma Linda (October 2022). Across the recent portfolio, work spans condensate pump replacement, steam trap maintenance and removal, heat exchanger installation and repair, boiler room piping, cooling tower cell replacement, sump pump replacement, and emergency valve and pressure regulator service.
Customer concentration is extreme: the Department of Veterans Affairs Veterans Integrated Service Network 22 accounts for 66 of 122 awards (54% of the portfolio) and $5.0 million of the $5.2 million combined potential value across all awards—96% of the dollar base. The remaining customer agencies (Department of Justice Bureau of Prisons Federal Correctional Complex Lompoc, Department of Health and Human Services Indian Health Service, Department of the Navy, and Department of the Air Force) collectively represent 1% of potential value. Warden has no parent vehicles or IDIQs; all federal work flows through direct purchase orders issued by VISN 22 and other customer agencies.
Activity has been stable: nine awards in 2022, eleven in 2023, twelve in 2024, declining to six in 2025, with one award placed year-to-date in 2026. One award (the $750 thousand emergency steam system contract) carries an ultimate completion date inside the next twenty-four months and represents recompete exposure. Warden has never subcontracted on federal contracts and carries no prime teaming relationships in the source data. The company was registered in SAM.gov in 2001 and has maintained continuous federal contracting activity with the VA since that time, with nearly all work performed at VA medical facilities in Southern California (Loma Linda, Long Beach, Artesia, West Los Angeles) and the Southwest (Phoenix, Arizona).
