Does homeowners insurance cover sewer line replacement?

Standard homeowners insurance usually does not cover sewer line failure caused by wear and tear. What your homeowners insurance may cover is the resulting damage – say, water cleanup inside the house after a backup – rather than the line repair. Some insurers sell a separate service-line endorsement that does help with the pipe; it's worth asking your agent before you ever need it. Always read your specific policy, because coverage varies.

Is pipe relining worth it?

For the right pipe, yes. If your line qualifies, you get a 50-year structural fix without sacrificing your yard, usually at a lower all-in cost than trenching. The value drops only when the pipe isn't a candidate – a collapsed or badly sagging line can't be saved by a liner, and forcing the method there just wastes money. The honest test is the camera inspection, not the marketing.

Why is sewer line replacement so expensive?

It comes down to labor and access. In Seattle specifically, sewer replacement can be expensive because older side sewers, mixed glacial soils, hillside lots, access limits, permits, and restoration work can all add labor and complexity. Roughly half of a typical bill is labor, and on hillside lots, a line can sit 8–15 feet down – every extra foot adds digging, shoring, and time. Add permits, restoration, and the occasional driveway or mature tree in the path, and the costs stack quickly.

How long do relined sewer pipes last compared with new replacement ones?

About the same, which surprises people. A properly cured liner is rated for 50-plus years, and so is a new PVC pipe. So when you reline sewer pipe sections instead of replacing the line, you are not necessarily trading lifespan for convenience. The longevity gap most homeowners imagine in the sewer pipe replacement vs. lining matchup mostly doesn't exist. What you're really choosing between is how much of your property gets disturbed to get there.

Can a collapsed sewer pipe be relined?

No – and this is the clearest line in the whole guide. Relining needs a host pipe to bond to, so a fully collapsed section has nothing to support a liner. In that scenario, you're looking at replacement, either by traditional dig or by pipe bursting. If only a short stretch has collapsed while the rest of the line is sound, a plumber can sometimes replace that section and reline the rest – but the collapsed part itself has to be physically rebuilt, not coated.
