Emergency plumbing in Seattle: what after-hours repairs cost

Emergency rates depend mostly on timing. These national figures come from Angi's emergency plumber cost guide, updated September 2026.

Angi says emergency plumbers charge 1.5 to 3 times as much as a typical plumber and gives a 2026 national average of $170 per hour. HomeGuide describes the same pattern: double or triple time on weekends, after hours and holidays, and time and a half or more on weekday nights. HomeAdvisor says trip fees run $50 to $300 and emergency calls outside regular hours add $100 to $300 or more.

Some problems justify after-hours rates; others can wait for a weekday quote once you have stopped the damage.

• Call someone now: water you cannot stop, sewage backing up into the house, no water at all in winter, or a leaking gas water heater. For a gas smell, leave first and call 911 and Puget Sound Energy; the numbers are on our emergency checklist.
• Stop it, then wait: a leak under a sink or behind a toilet that you can isolate with its local valve, a single clogged drain when other fixtures work, or a running toilet.
• Weekday job: a dripping faucet, a slow drain, low hot water from an aging heater that still works.

Closing the main shutoff often turns an emergency into a scheduled repair. HomeAdvisor notes that a pipe repair kit, about $25, can serve as a temporary fix while you wait for a professional.

1. Ask for the rate before anyone drives out: the trip or call-out fee, the hourly rate at this time of day, and the minimum charge.
2. Ask whether a temporary fix tonight and a full repair at weekday rates is possible. Often the plumber only needs to stop the leak or clear the line.
3. Get the price in writing before work starts, even if only by text or email, and ask for an itemized invoice.
4. Be wary of cash-only or pay-everything-now demands. A legitimate contractor can give you a written price and an itemized invoice.
5. Photograph everything before and after for your insurer.
6. Get the agreement in writing.L&I advises getting a written contract and making sure you understand its terms, getting references and staying alert for scams. For larger follow-up work, it recommends at least three written bids.

Even at midnight, a license check takes a minute. Search the company name in the L&I verify tool. It shows whether the contractor's registration is active, whether workers' comp is current, safety violations, and lawsuits against the contractor's bond. Ask the person who arrives for their L&I plumber certificate, too. Be wary of anyone who cannot give a company name, a license number or a written price.

For sewer emergencies in Seattle, remember that the side sewer belongs to the owner up to the public main. If your neighbors also have problems, or water is coming from the street, report it to Seattle Public Utilities first; the number is on our emergency checklist. Our side sewer repair page explains who repairs what.
