Sewer Line Repair and Inspection Basics

Backups, soggy lawns and recurring clogs can point below ground. See how sewer problems are found and repaired.

The sewer line carries everything from your home to the city main, and when it fails the symptoms show up in many fixtures at once. Because the pipe is buried, the first job is to see inside it. A camera inspection shows whether the problem is a blockage, roots, a crushed section or a joint that has shifted, and that decides the right repair.

Signs you may need Sewer Line Repair

  • Several drains backing up or gurgling at the same time
  • A toilet that bubbles when the washer drains
  • Sewage smell in the yard or near the foundation
  • A patch of lawn that stays wet or unusually green
  • Clogs that return soon after every cleaning

What Sewer Line Repair covers

Repair options depend on what the camera shows. A blockage can be cleared, a short damaged length can be replaced through a spot excavation, and a long failed run may need a different approach. You should see the findings and understand why a method is recommended.

How the process works

  1. 1

    Find the cleanout

    Most homes have an access point outside or in the basement that lets a camera enter the line directly.

  2. 2

    Inspect with a camera

    The video shows pipe material, roots, offsets, cracks and the exact distance to any problem.

  3. 3

    Review the findings together

    You see what is wrong and which repair methods fit the situation before anything is dug up.

  4. 4

    Repair and verify

    The damaged section is cleared or replaced, then the line is flushed and checked again.

What Denver adds to the picture

Many older Denver homes were built with clay tile or cast iron service lines that have been in the ground for generations. Joints open up, roots find them, and shifting soil can create low spots where waste collects. A camera check is a sensible step before buying or renovating an older house.

What you can do now

Do not run water, laundry or dishwashers during a backup because it adds volume to a line that has no room. Keep children and pets away from any overflow and avoid chemical cleaners that may splash back.

Questions about Sewer Line Repair

How do I know the problem is the sewer line and not one drain?

One slow fixture is usually local. When the lowest drains in the house back up or several fixtures react to each other, the main sewer line is the likely cause.

Is camera inspection worth it before a repair?

It shows what is actually wrong, so the repair is matched to the damage. It also gives you a record of the line condition.
