Sewer line repair in Knoxville, TN

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 for Knoxville homes

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.

Local conditions

Sewer line repair in Knoxville: what's different

Steep lots along the Tennessee River have long laterals that shift and crack, and older homes in Fourth and Gill have original clay and cast iron that fails.

A camera inspection shows the damage's location. Trenchless lining often avoids digging on slopes.

Permits come from the City of Knoxville Plans Review and Inspections or Knox County.

KUB provides wastewater service, and the lateral from the house to the main belongs to the owner. Crawl-space moisture also corrodes older cast-iron drains under the house, which a camera can check at the same time.

Sewer line repair questions in Knoxville

Are sewer repairs harder on Knoxville hillsides?

Yes. Long laterals on slopes are harder to reach.

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 many 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 U.S. cities and counties. Work in the street or sidewalk usually needs an additional right-of-way permit.
