Sewer Repair & Replacement in Capitol Hill
Seattle’s densest old neighborhood: mansions turned apartments, a hundred-year canopy, and combined sewers under all of it. A place where a camera inspection tells a building whether to keep clearing the line or fix the cause.
Pro Sewer Repair repairs and replaces side sewers in Capitol Hill, Seattle — camera-verified, permitted through Seattle Public Utilities, with BlueLight lining and pipe bursting where the line qualifies. Open 24/7/365; estimates and second opinions are free.
Capitol Hill is dense, old and shaded — all three matter underground
Capitol Hill has some of the oldest grand houses in Seattle, many of them long since divided into apartments, alongside brick apartment blocks from the 1920s and new mid-rises. It also has one of the heaviest tree canopies in the city, from Volunteer Park down every side street. And it sits on the part of Seattle served by combined sewers, where stormwater and sewage share the same pipes. When it rains hard, everything downstream is under load at once.
What that means for a building’s side sewer
- More fixtures on an old lateral. A house plumbed for one family now serves six units through the same clay pipe. Grease, wipes and volume the line was never sized for.
- Roots from the canopy. Mature trees find every mortared joint, and on Capitol Hill there is a lot of both.
- Rain-driven backups. In combined-sewer areas a surcharged main can push back up a lateral with a failed check or a low fixture. The camera and the timing of the symptom tell the story.
For property managers and HOAs
Capitol Hill is where our documentation-first approach earns its keep. A camera inspection shows you the condition of the line and the location of each defect, and you get written options — so a building that has been paying for quarterly drain cleaning can decide, on evidence, whether to keep clearing or to fix the cause. When it’s time to fix it, lining can rehabilitate a shared lateral from a single access point, often without opening a courtyard or a sidewalk, and pipe bursting replaces a failed run from small pits instead of a trench. Full replacements carry a transferable lifetime parts-and-labor warranty, subject to the written terms.
For homeowners
The single-family streets on the hill have the same clay-and-roots pattern as the rest of old Seattle, with the added wrinkle of steep alleys and tight lots. We scope it, show you every option, and help you choose the one that fits the property.
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 — we manage the permit requirements, and they’re explained and built into your written scope. Work in the street or planting strip can also need a separate SDOT permit. The permit and the inspection put the work on record for the next owner.
