West Seattle is a peninsula of hillsides

From the Admiral ridge down to Alki, from Genesee to the Fauntleroy ferry, West Seattle drops toward the water on three sides. Its neighborhoods filled in mainly from the 1920s through the 1950s, so the side sewers are a mix of late clay and mid-century concrete, with Orangeburg appearing in the postwar streets. Many of those laterals run downhill for a long way to reach a main, and the slopes above Alki and along the western bluffs have the same tendency to creep in wet winters as the rest of Seattle’s hillsides.

Common sewer problems in West Seattle

• Cracked concrete pipe from the 1940s and ’50s, often with roots in the crack.
• Offset joints on the slopes where the ground has moved and the rigid pipe stepped.
• Bellies at the bottom where a steep run flattens out and solids settle.
• Orangeburg in specific postwar blocks — a fibre pipe that softens and deforms with age.

Fixes that respect a West Seattle lot

West Seattle yards are the point of West Seattle. A BlueLight UV-cured liner bridges offset joints and seals cracks from a single access point; pipe bursting replaces a failed run from a pit at each end instead of a trench down a terraced slope. A collapsed section near the house is usually a targeted spot repair. Full sewer replacements carry a transferable lifetime parts-and-labor warranty, subject to the written terms. We put the camera in first and show you every option that applies.

Permits in Seattle

Side-sewer repairs and replacements inside Seattle city limits need a side-sewer permit, issued by Seattle Public Utilities since October 1, 2025. The side sewer is private property from the house to the connection at the public main, so the permit is the homeowner’s responsibility — which is why we handle it as part of the job and put it in the estimate. Work in the street or planting strip can also need a separate SDOT permit. The permit puts the work on record for the next owner.
