What does a plumber cost in Seattle?

Angi's Seattle plumber cost guide, updated in July 2026, says most Seattle homeowners spend about $522 on a plumbing job, with a typical range of $284 to $760. Angi gives a general hourly range of $45 to $200 and says Seattle plumbers usually charge closer to $150 to $200 per hour. Many companies also charge a trip fee of $75 to $200, which may cover the first hour of labor.

For a national comparison, HomeGuide's 2026 plumber cost guide puts typical plumber rates at $45 to $150 per hour and service call fees at $50 to $200, usually covering the first hour. Seattle sits at the upper end of national ranges; Angi points to the region's higher cost of living and labor rates.

What do common jobs cost?

Job	Seattle range (Angi, 2026)	National range (HomeGuide, 2026)

Faucet or fixture replacement	$150 to $600	not listed
Toilet installation	$300 to $800	not listed
Water heater installation	$800 to $2,000 flat rate	$600 to $1,800 (tankless $800 to $3,500)
Main water line leak repair	$600 to $4,500	not listed
Burst pipe repair	$1,000 to $4,000	pipe repair $400 to $2,000

These are published ranges, not quotes. The two guides group jobs differently, so compare a bid against the line that best matches your job, and read our service pages on drain cleaning, water heaters and leak detection for more detail.

How much more do nights and weekends cost?

Angi says emergency work on nights, weekends and holidays usually costs about 1.5 to 2 times the normal hourly rate. HomeGuide's national guide says weekend, after-hours and holiday work is often billed at double or triple time. If the problem can be safely contained by shutting off the water, waiting for regular hours can cut the bill substantially. Our emergency guide explains how to stop the damage first.

What do permits add in Seattle?

In Seattle, plumbing permits come from Public Health Seattle and King County. Its fee schedule effective January 1, 2026 lists:

• Plumbing or backflow permit: $137 plus $27 per fixture
• Re-inspection: $137
• Permit renewal: $68
• Already Built Construction permit, for work done without a permit: $273 plus $55 per fixture

Repipe projects carry a supplemental fee based on the expected number of inspections. Side sewer work outside the house is permitted separately by Seattle Public Utilities. Its side sewer permits page says a sanitary repair permit on private property generally costs $280 and a drainage repair permit $375, each including one to two inspections. Suburbs set their own fees; see our location pages.

Note the Already Built Construction fee: legalizing unpermitted work costs roughly twice the normal per-fixture rate, which is one reason not to accept a contractor's offer to skip the permit.

What does side sewer work cost?

Side sewer repairs are often the largest plumbing bill a Seattle homeowner faces. SPU's Troubleshooting Your Sewer Problem guide says a repair that does not require digging could range from $60 to $200 per foot, and a repair that requires digging in the public right of way would cost even more. Nationally, Angi's sewer line replacement guide puts the average replacement at $3,319, with a typical range of $225 to $10,000. Our side sewer repair options guide compares methods.

What drives the price up or down?

• Access. Pipes behind finished walls, under slabs or in tight crawlspaces take longer. Angi notes that older homes and hard-to-reach sites push costs toward the high end.
• Home age. Angi names century-old homes in neighborhoods such as Capitol Hill, Queen Anne and Wallingford as likely to need pipe upgrades. See our old house plumbing guide.
• Materials. Who supplies fixtures and whether they are included in a flat rate changes the total.
• Permits and restoration. Ask whether the price includes permit fees, inspections and patching drywall or landscaping.

How do you use these numbers?

Get at least two or three written bids for anything beyond a small repair, and make sure each one covers the same scope. A bid far below the ranges above deserves questions about what is left out; one far above should come with a clear reason. Before you sign, check the company's license in the L&I Verify tool. Our hiring guide walks through the full checklist.
