About Seattle Plumber Pros: an independent plumbing guide for Seattle

Operator, address and commercial register entry are listed in the legal notice. Full company details are in our legal notice, and how we handle information you send us is described in our privacy policy.

We have no office, workshop or staff in Washington. We have no phone line, no vehicles and no technicians.

Seattle Plumber Pros is not a plumber, not a plumbing business and not a contractor of any kind. We hold no Washington contractor registration, no plumbing contractor license and no plumber certificate, and we do not perform, supervise, schedule, price or guarantee any plumbing, sewer or water heater work. Nothing on this site is an offer to do that work.

That distinction matters in Washington. RCW 18.106.020 says no person may engage in or offer to engage in the trade of plumbing without a journey level, specialty, residential service, temporary or trainee certificate, and, since 2021, no contractor may employ someone in the trade unless the contractor is a licensed plumbing contractor under that chapter. L&I explains that all plumbing contract work must now be done by a licensed plumbing contractor that designates a certified plumber for the company. Any work on your home should be done by a contractor that holds the licenses that apply to that job.

• Explain costs. We summarize published ranges from cost guides such as HomeGuide, HomeAdvisor and Angi, labeled with the source and year, and say when a figure is national rather than local.
• Explain rules. We link to official pages from Washington L&I, the Washington State Legislature, Public Health Seattle and King County, Seattle Public Utilities, Seattle City Light and Puget Sound Energy, and summarize what they say.
• Explain warning signs and first steps, such as where the shutoff usually is and whom to call if you smell gas.
• List licensed plumbers. Guide pages show licensed plumbers with phone numbers and license numbers, and all listed contractors are on one page. The list is unpaid and is not a ranking.
• Answer questions by email. See below.

• We do not send anyone to your home or respond to emergencies.
• We do not quote, set or negotiate prices, and we do not take payments for plumbing work.
• We do not publish customer reviews, ratings or testimonials. Our reviews page explains why.
• We do not guarantee any contractor's work. That includes the contractors listed on this site: your contract is with the one you hire.

Today it does not. Reading the site and emailing us are free for homeowners. We receive no payment or other compensation from the contractors listed on this site. Inclusion in the list is free. We may in future offer clearly labeled ad placements on this site; if that starts, this page will say so, and an ad will never decide what our guides say about costs, licensing or permits.

1. Call a listed contractor. Each guide page shows licensed plumbers with a phone number, license number and website, and all listed contractors are on one page in alphabetical order. The order on guide pages changes daily and is not a ranking.
2. Check the license yourself in the L&I verify tool before you hire, even for a listed contractor.
3. Email us if you prefer. Send your question to dispatch@seattleplumberpros.com with your city or ZIP code and a description of the problem. We reply with next steps, such as what the problem likely involves, what to ask and which permits and licenses apply. The contact page lists what helps most.
4. Any estimate, contract, payment and warranty is strictly between you and the contractor you choose.

• Official sources first. For licensing, permits, utility rules and safety we use the agency's own page: Washington L&I, the Revised Code of Washington, Public Health Seattle and King County, Seattle Public Utilities, Seattle City Light, Puget Sound Energy, the CPSC and the FTC.
• Cost guides are labeled. Cost figures come from published consumer cost guides and are shown as that guide's estimate, with its year. Most are national ranges. They are not our prices.
• Every figure has a source. Each page lists the sources we opened and used. If we cannot verify a number, we leave it out.
• No invented content. We do not publish made-up reviews, case studies, statistics or staff profiles.
• Dated reviews. This content was last reviewed in October 2026. Fees, rebates and rules change, so check the linked source before relying on a figure.
• Corrections. If you find an error, email us with the page and the correct source and we will review it.

Use the L&I verify tool to confirm that the company's license or registration is active and to see workers' comp status, safety violations and bond lawsuits. Ask the person doing the work for their L&I plumber certificate. L&I's hiring advice adds: get at least three written bids, get references, and get a written contract you understand. Hiring a registered contractor does not guarantee there will be no problems, but L&I says it may give you protections that are not available otherwise.

Contractors are listed on this site only if they meet the criteria on how we select, which also explains how to request free inclusion or removal. Listing is free and unpaid, and being listed is not a ranking, an endorsement of any job or a guarantee.
