Sewer Line Repair in Kenmore, WA: Root-Damaged Sections Cut Out and Rebuilt
Done Right Plumbing repairs side sewers across Kenmore, from Moorlands and Inglewood to Uplake, Arrowhead and the blocks above Log Boom Park. We find the failure with a camera, cut out the section that failed, rebuild it in PVC and add a cleanout, so the rest of a sound line stays in the ground and the next problem can be reached from outside.
Real Work in Kenmore
In September 2025, a homeowner in Moorlands called about a side sewer that was giving trouble. When Steven and Jeremy opened the line beside the house, they found a patchwork that is common in Kenmore: newer PVC on both ends, and sandwiched between them a short stretch of the original concrete pipe, where tree roots had grown in through the old joints.
The crew removed the damaged concrete section, rebuilt it so the line runs in PVC from end to end through that stretch, and installed a new cleanout at the house. With the cleanout in, they ran a camera down the rest of the sewer toward the street, and everything downstream looked normal, so the repair stopped where the problem did.
A few blocks away in August 2026, Nick and Jeremy hydro-jetted another Moorlands side sewer that had stopped draining. The camera run afterward showed what caused it: tree roots, in an old concrete pipe that had turned brittle and was falling apart. That kind of finding is why we camera a line after clearing it, so the owner knows whether the next step is maintenance or a repair. Elsewhere in Kenmore, our Kenmore sewer cleanout job story shows a two-way cleanout added to a line that had never had one.
What We Do on a Kenmore Sewer
Camera inspection and locating
We run a camera through the line to see what failed and where, then locate it from the surface so any digging lands in the right spot.
Spot repairs on root-damaged sections
When roots have broken into one stretch of old concrete or clay, we excavate that section, replace it in PVC and leave the sound pipe alone.
Cleanouts
A cleanout outside the house turns every future clearing or camera run into an outdoor job. We add one on most repairs where the line lacks it.
Hydro-jetting and lining
Where roots are spread along the line, we jet it clean, and where a long run is failing we can line it. Our sewer line repair page and trenchless sewer repair page cover both.
What Makes a Kenmore Sewer Job Different
Northshore Utility District rules
In Kenmore the sewer main belongs to the Northshore Utility District, not the city, and the side sewer from your house to that main is yours. The city's code puts side sewer installation and repair under the district's rules, including the district's permits, along with any permit the City of Kenmore itself requires. We confirm both before the work starts.
Concrete pipe, patched over the years
Kenmore side sewers we open often started out as concrete pipe and have been partly replaced as sections failed, which leaves short runs of the old material between newer PVC. Those leftover joints are where roots get in, as they did in Moorlands, so a camera run before and after a repair matters here.
Big trees on sloping lots
Kenmore steps down toward the lake and the Sammamish River under a canopy of mature trees. Roots go looking for the moisture in old sewer joints, and slopes make guesswork digging expensive, so we locate before we excavate.
FAQs About Sewer Line Repair in Kenmore
Who handles sewer permits in Kenmore?
The Northshore Utility District, which owns the sewer mains in Kenmore. Kenmore's city code requires side sewers to be installed and repaired under the district's rules, including its permits, plus any permit the city requires. The side sewer from your house to the district main is yours, and we handle the permits for the repair.
Why do roots keep getting into my Kenmore sewer line?
Most of the time, the roots are getting in through an old concrete or clay section with open joints. Many Kenmore lines are part old pipe and part newer PVC, and the old joints are where roots find water. Clearing them buys time, but replacing that section in PVC is what keeps them out.
What does sewer line repair cost in Kenmore?
In our recent work around the region, a camera inspection runs about $250 to $475, a spot repair on one failed section roughly $2,800 to $5,000, and a two-way cleanout about $3,800 to $4,800. In Kenmore, the depth of the line, the slope of the lot and what sits above the pipe decide where a job lands.
