Your Kenmore Plumber
Kenmore sits where the Sammamish River meets the north end of Lake Washington, and it has only been a city since 1998, which is why its neighborhoods still go by the names of the old plats: Arrowhead and Inglewood on the lake side, Lower and Upper Moorlands to the east, Linwood Heights and Uplake Terrace on the hills to the northwest, and the downtown blocks along Bothell Way where most of the new building has gone up. Stollwerck Plumbing & Sewer works across the city from our shop in Old Town Mukilteo, about forty minutes away down I-405 or Bothell Way, and every person we send is a licensed plumber on our own crew. Two things are worth knowing before you call. Northshore Utility District provides both the water and the sewer in Kenmore, and it buys all of its water from Seattle, which means the Tolt River supply, soft and low in minerals. And plumbing permits in Kenmore are issued through the MyBuildingPermit portal the city shares with Bothell, Kirkland and its other neighbors, so a licensed contractor can pull one online.
Services we provide in Kenmore: remodel plumbing, faucet repair, toilet repair, water heaters, water leak repair, drain cleaning, water pressure and PRVs, sewer repair and camera inspection, garbage disposals, gas lines, emergency plumbing and commercial plumbing.
Services Offered in Kenmore
Remodel Plumbing
The plumbing scope of a bathroom or kitchen remodel: the rough-in for a new tub, shower or vanity, then the trim-out once the tile and cabinets are in. Most of our Kenmore work so far has been exactly this.
Faucet Repair
Cartridges, stems and whole faucets, plus the shutoffs under the sink that fail at the same age. A leaking stop under a Kenmore kitchen sink was one of our first calls in the city.
Toilet Repair
Rebuilds, resets and replacements, dye tested before we leave. Commercial flushometers too, which matters for the public buildings in town.
Water Heater Services
Tank and tankless water heaters repaired or replaced, with the expansion tank checked and the permit pulled through MyBuildingPermit.
Water Leak Repair
Leaks in supply lines, under sinks and in crawl spaces, found and repaired, with a pressure reading taken on the way in.
Commercial Plumbing
Public buildings and businesses, including prevailing-wage work. We have rebuilt flushometers at a fire station in Kenmore on exactly those terms.
Real Work in Kenmore
Our largest Kenmore project to date was the plumbing scope of a master-bath remodel in north Kenmore, run by the homeowners' builder and carried out over three visits in the spring of 2026. On the first day Logan and Willie walked the room with the homeowners to set the fixture locations, demolished the old water and waste lines, stubbed out new copper for the vanity stops and a new stop for the toilet, and laid out a freestanding tub where a deck-mounted one had been, which meant pulling the tub out of the room and building a new drain under the floor. The second day finished the rough-in: the island tub drain, the floor-mounted filler rough, a new shower valve, all set where the homeowners had approved them, the water run to each, the house re-pressurized and checked for leaks, and the waste system filled for inspection. Two weeks later the test was pulled and the fill point capped, and in May the crew came back for the trim-out: four angle stops, two widespread lavatory faucets and their drains, the shower trim with a slide bar, a right-height two-piece toilet, and the tub itself assembled onto its island drain with the Roman tub filler beside it.
In July the homeowners mentioned that the new toilet's fill valve was noisy, so Willie and Logan replaced it under our one-year guarantee, flushed it several times and left with the tank filling quietly and faster than before. That is what the guarantee is for.
Our Kenmore calls are not all remodels. In September 2025 Logan was called to a kitchen in the Arrowhead area where the hot-side double stop under the sink, the valve that feeds both the faucet and the dishwasher, had started to leak. He pulled it, installed a new double stop in its place, reconnected the sink and dishwasher supplies and tested both. And in October 2025 J.D. rebuilt two flushometers at a fire station in Kenmore on a prevailing-wage call, the kind of public work that needs the insurance we carry above the state minimum.
Common Plumbing Issues in Kenmore Homes
Arrowhead and Inglewood: The Lake Side
Arrowhead began as summer cabins on the lake shore, and its oldest standing house dates from the 1920s, while Inglewood was platted in the 1950s and built out as a suburb within a decade. Both sit low near the water on crawl spaces, which is where we look first when a floor is soft or a supply line is weeping. The original brass angle stops and supply stubs in these houses are at the end of their lives, and the kitchen stop we replaced in the Arrowhead area is a typical call.
Upper and Lower Moorlands, Linwood Heights and Uplake Terrace: The Postwar Hills
The hillside plats filled in through the late 1930s, the 1950s and the 1960s, and those houses are now on their second or third round of fixtures. This is where the remodel calls come from: a deck-mount tub giving way to a freestanding one, a single vanity becoming a double, a shower valve moved to where the new tile wants it. The plumbing on a job like that is a rough-in, an inspection and a trim-out, and we work to the builder's schedule.
Downtown Kenmore and Lakepointe
The blocks along Bothell Way between the river and the lake have changed more than anywhere else in the city since incorporation, with apartments, townhomes and mixed-use buildings replacing the old highway frontage. That is commercial and multi-unit work, and it sits with the public buildings in town under our commercial plumbing service.
Soft Water, Old Valves
Northshore Utility District's water comes from Seattle's Tolt River supply and is soft, so Kenmore fixtures do not scale up. What fails instead is rubber and worn brass: faucet cartridges, toilet fill valves, the packing in a shutoff that has not been turned in twenty years. A valve that will not close is the thing to fix before the day you really need it closed.
The Stollwerck Difference
Licensed Plumbers, Not Contractors
Everyone we send holds a plumbing license and works for us, so the crew that roughs in a remodel in the Moorlands is the crew that comes back for the trim-out.
Insured Above State Mandates
We carry more coverage than Washington requires, which is why public agencies and building owners can bring us onto prevailing-wage jobs a residential-only plumber cannot touch.
A One-Year Guarantee
Every repair and installation is guaranteed for a full year. The noisy fill valve on that Kenmore remodel was replaced at no charge, which is exactly how it is supposed to work.
Kenmore Plumbing FAQs
Is Northshore Utility District responsible for both my water and my sewer in Kenmore?
Yes. Northshore Utility District runs both the water mains and the sewer mains in Kenmore, along with parts of Bothell, Lake Forest Park, Kirkland and Woodinville, and bills for both. On the water side your pipe starts at the meter. On the sewer side you own the side sewer out to the district's main, as in most of King County.
Where do plumbing permits for a Kenmore bathroom remodel come from?
From the City of Kenmore, through the MyBuildingPermit portal it shares with Bothell, Kirkland and other eastside cities. Moving a tub drain, adding a shower valve or replacing a water heater need one, and the inspection happens with the waste system on test before the walls close. We pull the permit and schedule the inspection as part of the rough-in.
Why do the shutoffs under my sinks leak when I finally turn them?
Because a valve that sits open for twenty years dries out its packing and seats, and the first turn is what breaks the seal. Kenmore's soft Tolt water leaves no scale to hold a worn valve together. We replace a leaking stop with a new double stop, as Logan did under an Arrowhead-area kitchen sink, and check its neighbors.
Will you come to Kenmore for one small job, like a leaking valve or a running toilet?
Yes. A leaking stop under a kitchen sink was one of our first Kenmore calls, and it took one visit. We group routine Kenmore work with our other King County stops so the drive is not wasted, which usually means a day or two out, and an active leak goes to the front of the line the same day.
Do you work on public buildings in Kenmore, like the fire station?
Yes, on prevailing-wage terms. We carry insurance above the Washington minimum and file the intent and affidavit paperwork that public work requires, which is how we came to rebuild two flushometers at a fire station in Kenmore. Facility managers for public and commercial buildings can read more on our commercial plumbing page.
