Water leaking right now? Do this first
Stop the water first, then call. The sooner the main valve is closed, the less there is to dry out.
- Close the main shut-off valve. It is usually where the water line enters the house, often in the basement, crawlspace or garage. Turn it clockwise until it stops. Find it before you need it.
- Shut off the water heater if it is the source: switch off its breaker (electric) or turn the gas control to "pilot" or "off" (gas).
- Keep water away from electricity. Do not step into standing water near outlets or appliances.
- If you smell gas, leave the house without touching switches, then call 911 and PSE at 1-888-225-5773 from outside.
- Book a plumber. Take photos of the damage for your insurer, and keep the receipts if you plan to ask Seattle Public Utilities for a leak adjustment (see below).

Repair or replace? The plumbing problems older Seattle homes have
Repair when the problem is one fitting, one fixture or one section of pipe. Consider replacing when the same system keeps failing, because each repair visit adds a trip fee and the next leak is usually close to the last one.
- Galvanized steel pipe. Common in older Seattle houses. It rusts from the inside, so pressure drops and the water can run brown. One leak can be patched; low pressure throughout the house usually means repiping.
- Lead and copper at the tap. Seattle Public Utilities reports no detectable lead in its source water, and says the lead or copper sometimes found in home tap samples comes mainly from corrosion of household plumbing. When your plumbing was installed and what it is made of both matter.
- Water heaters. A leak from the tank itself means replacement; a leak from a valve or fitting can often be repaired.
- Fixtures. Faucets, toilets and disposals are usually cheaper to replace than to rebuild once parts are hard to find.

Water heaters in Seattle homes
We repair and replace tank, tankless and heat pump water heaters. A replacement in Seattle has three code details that a quick swap can miss:
- A plumbing permit. Installing or changing a water heater needs a permit from Public Health, Seattle and King County. We pull it for every installation.
- Earthquake straps. The tank must have two 20-gauge metal straps, one in the upper third and one in the lower third.
- An expansion tank where the water system is closed, so heated water has somewhere to go besides the relief valve. Gas heaters also need correct venting and combustion air.
Heat pump water heaters: Seattle City Light offers a $750 instant discount on a qualifying (Tier 3 or 4) heat pump water heater installed by a contractor who buys it through a participating distributor. Home Comfort Alliance is an approved Seattle City Light contractor.

Do you need a plumbing permit in Seattle?
Yes, for most work beyond simple repairs. In Seattle, plumbing and gas piping permits are issued and inspected by Public Health, Seattle and King County, not by SDCI. A permit is required whenever a plumbing or gas piping system is installed, relocated or changed, and gas piping takes its own separate permit.
Homeowners can pull a permit for their own work, but a professional must be a registered contractor. We pull the required permits for every installation and meet the inspector, so the work is on record when you sell or insure the house.
Leaks and your Seattle Public Utilities bill
Seattle Public Utilities (SPU) gives billing adjustments for most leaks, but only if the repair is done within 60 days of the first high bill that showed the leak. Keep the invoice and photos: SPU asks for proof of the repair.
A leak underground, between the water meter and the foundation, needs one more step. SPU must inspect the repair before the trench is backfilled, so tell us at booking and we will leave the line open until the inspection is done. Details are on SPU's leak adjustment page.

As a regional benchmark, Angi puts most Seattle plumbing jobs at $284 to $760 and hourly rates around $150 to $200 (July 2026).
How do I find a good plumber in Seattle?
Check that the company is a registered contractor with a plumbing contractor license on the Washington L&I "Verify a Contractor" lookup, that it gives a written price before work starts, and that it pulls permits with Public Health, Seattle and King County. Home Comfort Alliance holds WA Contractor Reg. #HOMECCA785BD and Plumbing Contractor Lic. #HOMECCA751QG.
Who issues plumbing permits in Seattle?
Public Health, Seattle and King County issues plumbing and gas piping permits in Seattle and does the inspections, not SDCI. A permit is needed whenever a plumbing or gas piping system is installed, relocated or changed.
Does replacing a water heater in Seattle need a permit?
Yes. The new heater also needs two seismic straps, and an expansion tank where the water system is closed. We pull the permit for every water heater installation.
Will Seattle Public Utilities lower my bill after a leak?
Often, yes. SPU offers adjustments for most leaks if the repair is made within 60 days of the first high bill, with proof of the repair. An underground leak between the meter and the house must be inspected by SPU before it is backfilled.
Is there a rebate for a heat pump water heater in Seattle?
Yes. Seattle City Light offers a $750 instant discount on a qualifying Tier 3 or 4 heat pump water heater installed by a contractor through a participating distributor. Home Comfort Alliance is an approved Seattle City Light contractor.
Can I get a plumber the same day or after hours?
You can book by phone or online. Our plumbers work Monday to Friday, 8 AM to 5 PM, with same-day service when possible, and same-day recommended plumbing work takes $50 off. A call after hours is scheduled for the next business day.
Do you work on sewer lines?
No. We clear indoor drains, including hydro jetting, but we do not repair, replace or camera-inspect sewer lines or side sewers.
Do you do commercial plumbing?
No. Our plumbing license covers residential work, so we work on houses, condos and townhomes.
Is it worth repiping an older Seattle house?
When old galvanized pipe causes low pressure, rusty water or repeated leaks, repiping usually costs less over time than patching leak after leak. We quote repiping after a free site visit, and financing is available.
What warranty comes with your plumbing work?
Installations carry a 1-year labor warranty, and we support the manufacturer's warranty on covered equipment parts. Home Comfort Club members with a new system installed by Home Comfort Alliance get extended labor coverage, up to 5 years from installation.
