Sewer line repair and replacement

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.

About sewer line repair

Sewer repairs are big decisions, so they should start with a camera video and a locator showing exactly where the defect is. One cracked joint near the foundation is a very different job from a line that's collapsed in three places under the street.

Work in the public right-of-way, or on the tap at the main, usually needs a permit from the city and sometimes a separate street-cut permit.

Sewer line repair questions

What is trenchless sewer repair?

Methods that fix the pipe without digging a full trench. Lining cures a resin tube inside the old pipe; pipe bursting pulls a new pipe through while breaking the old one. Both need access pits at one or both ends.

Who pays for a sewer line under the street?

In most Front Range cities the homeowner owns the service line out to the main, including the part under the street. Rules vary, so check with your city or sanitation district.

Do I need a permit to replace a sewer line?

Yes, in most Front Range cities and counties. Work in the street or sidewalk usually needs an additional right-of-way permit.

How long does a sewer line replacement take?

Many trenchless jobs take one to two days; open-trench replacements can take longer, plus time for permits and inspections.

Can I use my plumbing during a sewer repair?

Usually not while the line is open. Plumbers often schedule work so the house is without sewer service for the shortest possible time.

Does homeowners insurance cover sewer line repair?

Standard policies often exclude wear, roots and soil movement. Some insurers and utilities offer optional service line coverage.
