Plumber in Kenmore, WA
Leaks, clogs, a water heater that has given up, or a remodel that needs new lines: our licensed plumbers handle residential plumbing across Kenmore from our Redmond branch. Call (425) 645-0404 or use the form, and you will get a written price before any work begins.
Kenmore’s water and sewer service comes from Northshore Utility District, a special purpose district headquartered in the city (City of Kenmore, utility providers). The district looks after the mains and meter; everything on the house side of the meter, from the service line to the fixtures, is the homeowner’s responsibility, and that is where we come in.

District side or house side?
When water pressure changes suddenly or water appears in the yard, the first question is whose pipe it is. Northshore Utility District asks customers to report leaking water lines, sewer service line issues and high or low pressure to the district (City of Kenmore, utility providers). A quick way to narrow it down:
- Turn off every fixture and appliance that uses water.
- Look at the meter. If it still moves, water is leaving the system somewhere past the meter, on your side.
- Close your main house shutoff. If the meter stops, the leak is inside the house; if it keeps moving, it is in the service line between the meter and the house.
Either way, we can find and repair leaks on the house side, including service lines, and we tell you when a problem belongs to the district.
Water heaters
We repair and replace tank, tankless and heat pump water heaters. Kenmore homes have both PSE electricity and PSE gas available (City of Kenmore, utility providers), so every option is on the table:
| Option | Why choose it |
|---|---|
| Heat pump water heater | Much lower electricity use than a standard tank; PSE rebate of $1,000 ($1,100 with Efficiency Boost) |
| Gas tank | Lowest purchase price where gas is already piped |
| Tankless gas | Continuous hot water for larger households; wall-mounted to save space |
| Standard electric tank | Simple swap in tight spaces |
Rebate: PSE heat pump water heater rebate. The City of Kenmore requires a permit to install or replace plumbing and gas systems regulated by the building code (City of Kenmore, Do I Need a Permit?), and we file it.
Water pressure problems
Pressure that is too high is as much of a problem as pressure that is too low. High pressure makes pipes bang when a faucet shuts, wears out toilet fill valves and appliance hoses early, and can make a water heater’s relief valve drip. Low pressure shows up as weak showers and slow-filling tubs. On the house side, the usual causes are a failing pressure-reducing valve, a partly closed main shutoff, or corroded older pipe. A plumber can test static pressure at a hose bib in a few minutes. If pressure is off at the meter itself, that is a question for Northshore Utility District, which asks customers to report high or low pressure to it (City of Kenmore, utility providers).
Townhomes and condos
Kenmore’s newer townhomes and condos near downtown and along Bothell Way bring their own plumbing situations. Water heaters are often in closets or garages with little room, so replacements need careful sizing and venting, or a compact heat pump or tankless unit. A leak can affect a neighbor below or beside you, so knowing where your unit’s shutoff is matters more than in a detached house. Many associations also have rules about who can work on shared lines and when; bring those to the visit and we will work within them.
Signs your water heater is near the end
- Rust-colored hot water, or rust around the fittings.
- Rumbling or popping as the tank heats, a sign of sediment build-up.
- Moisture or a slow drip at the base of the tank.
- Hot water running out sooner than it used to.
- A tank that is more than about ten years old.
Replacing a water heater before it fails lets you choose the type, check the PSE rebate, and avoid water damage.
Leaks, drains and fixtures
- Dripping faucets, running toilets and failed fill valves.
- Leaking supply lines and stiff or leaking shutoff valves.
- Kitchen, bath and laundry drains that clog or run slowly.
- Main drain backups, cleared from an indoor cleanout (we don’t do sewer line work).
- Garbage disposals, dishwashers and ice-maker lines.
- New faucets, sinks, toilets and shower valves.
Lower levels near the lake and river
Homes in the lowlands near Lake Washington and along the Sammamish River often have daylight basements or crawlspaces that stay damp through the cooler months, which the damp, cool winters make worse. Plumbing there deserves an annual look: check for sweating cold-water pipes, test sump pumps and their check valves, confirm that floor drains are not dry (a dry trap lets sewer gas in), and make sure any backwater valve on the sewer line opens freely.
Remodels and repiping
If you are updating a kitchen or bathroom, bring a plumber in at the planning stage. Moving fixtures changes drain slope and venting, and it is far cheaper to settle those details before cabinets are ordered. For homes where old supply lines are leaking in more than one place, repiping the house with modern materials is often more economical than chasing repairs one at a time. We rough in, set fixtures and pull the city permit.
Winter and rainy-season prep
- Disconnect hoses and protect outdoor faucets before the first frost.
- Insulate pipes in crawlspaces, garages and on exterior walls.
- Keep gutters and downspouts clear and pointed away from the foundation.
- Label the main shutoff and make sure it turns freely.
- Replace rubber washing machine hoses with braided ones.
How a plumbing visit goes
When you book, the coordinator asks what you are seeing and where, so the plumber arrives with the likely parts. On site, the plumber confirms the cause before quoting, explains the choices (a repair, a replacement part, or a larger fix if the problem keeps coming back) and gives you each price in writing. Once you approve, the work is done, tested for leaks and flow, and the area is cleaned up. If the plumber spots something else worth attention, such as a corroded shutoff or a water heater near the end of its life, you get a note about it without pressure to act on the spot.
When to call right away
- Water you cannot stop: close the main shutoff and call.
- Gas smell near a gas water heater: leave the house and call PSE and 911 from outside.
- Sewage backing up into a tub, shower or floor drain.
- A water heater relief valve that will not stop running.
