Sewer line repair in Seattle, WA
A damaged sewer line can be fixed with a spot repair, a trenchless liner, pipe bursting or an open-trench replacement. Which one fits depends on what the camera shows, how deep the pipe is, and what's on top of it, such as a driveway, trees or landscaping.

Sewer line repair in Seattle: what's different
Seattle homeowners own their side sewer from the house to the public main, and in Ballard, Wallingford and Queen Anne many are original clay lines running down steep yards. Roots, cracked joints and sags from saturated soil are the usual failures.
Repairs range from a spot fix to a full replacement or trenchless lining, and side sewer work needs a permit from the City of Seattle. On steep lots, lining or pipe bursting often avoids a long trench through terraced yards and retaining walls.

Why is my basement floor drain backing up?

For homes built before about 1980, or with large trees in the front yard, a sewer scope is worth it. A standard home inspection doesn't look inside the sewer line, and in most U.S. cities the buyer will own that line, often all the way to the main.
