Washington Plumbers

Hiring a Plumber in Washington

Buildermuse currently lists 10 plumbers in Washington, averaging 4.9 stars across 11,053 verified Google reviews. That is an unusually strong field — when nearly every firm clears 4.8 stars, response time and availability become the real differentiators, so call two or three rather than only the top result. Most of the crews above operate out of Auburn, Bellevue, and Seattle.

Washington licenses this trade at the state level: the Plumbing credential is required for all work, regardless of project size. Licensed through L&I Plumbing Section. Licenses renew on a two-year cycle (registration date). Expect a $171 state application fee. Verify any license directly with the Washington Department of Labor & Industries at (800) 647-0982 before signing a contract.

Labor is the biggest line item on most bids, and the Washington market sets the floor: construction workers here average $40.95 an hour — about $85,176 a year — across 217,000 workers statewide, per Bureau of Labor Statistics data. That puts Washington among the pricier construction labor markets in the country, so expect quotes to reflect it.
