Government contracts for plumbers in Washington

Plumbers contracts in Washington typically cover backflow-preventer testing, water-main repair, fixture replacement at federal buildings, sewer-line work at correctional facilities, and on-call plumbing IDIQs. Federal posts in this category fall under NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors), and the bulk of the work flows to the Army Corps of Engineers, the Federal Bureau of Prisons, and GSA. Small-business set-asides are common because most jobs sit well below the simplified acquisition threshold.

Washington currently has 2 open plumbers contracts in our database, with 2 added in the last 30 days. Volume in smaller markets is lumpy: a single base or facility can drive a quarter of annual postings. The most active buyers are Washington (1 open posts) and King County (1), with the rest spread across other federal civilian agencies, DoD components, and state and local departments active in Washington.

Beyond federal opportunities, much of the plumbers work in Washington is posted through Washington's Electronic Business Solution (WEBS), with recurring buyers including WSDOT, the University of Washington / Washington State University, and Sound Transit. Washington's Office of Minority and Women's Business Enterprises (OMWBE) certification is the gate for most diversity-set-aside spend at the state level. ContractRadar pulls federal postings from SAM.gov alongside state and local feeds so a plumbing contractor doesn't have to monitor each portal manually.
