# Seattle Plumber Pros

> Seattle Plumber Pros is an independent homeowner guide to plumbing in the Seattle area, Washington, operated by SWKM GmbH (Munich, Germany). Not a licensed contractor: the site does not perform, price or guarantee any work. It explains costs, warning signs and how to hire and verify a licensed contractor, and accepts referral requests by email (dispatch@seattleplumberpros.com). Updated 2026-10-17.

## Key facts
- Most Seattle plumbing quotes can be compared with national cost guides: HomeGuide's 2026 guide puts plumber labor at $45 to $150 per hour and unclogging a drain at $100 to $275. Seattle owners also own their side sewer all the way to the public main, and a sanitary repair permit from Seattle Public Utilities generally costs $280. Verify any plumbing contractor in the L&I lookup first.
- Verify any contractor license with the Washington State Department of Labor & Industries (L&I) (https://secure.lni.wa.gov/verify/) before signing.
- No phone line, no technicians, no reviews published. Requests by email only.
- Operator: SWKM GmbH, Kathi-Kobus-Straße 21, 80797 München, Germany, HRB 206143 (Amtsgericht München).
