Sewer Line Repair & Replacement

A damaged sewer line is one of the most serious plumbing problems a homeowner can face. Sewage backups, contaminated soil, and foundation damage are all possible consequences of an untreated sewer failure. Copper Hound provides fast, professional sewer diagnosis, repair, and replacement using video camera inspection and the latest repair technology.

Signs You Have a Sewer Line Problem

Multiple drains backing up or gurgling simultaneously
Sewage smell inside the home or in the yard
Unusually lush, green, or soggy patches in your lawn
Toilets that bubble when other fixtures are used
Persistent clogs despite repeated clearing

Our Diagnostic Process

Before recommending any repair, we run a video camera through your sewer line to see exactly what's happening — root intrusion, pipe collapse, offset joints, or blockage. This eliminates guesswork and ensures we recommend the right repair.

Repair Options

Root clearing and treatment — mechanical cutting and chemical treatment
Pipe relining (trenchless) — resin liner installed inside the existing pipe
Targeted spot repair — excavation and replacement of a specific damaged section
Full sewer line replacement — new modern PVC line from home to street

Frequently Asked Questions

A clog typically affects a single drain. When multiple fixtures back up or gurgle simultaneously — especially when flushing a toilet causes drains to back up elsewhere — that points to a main sewer line problem. A camera inspection is the only way to know for certain.

Yes — it's one of the most common causes of sewer line damage in older NH neighborhoods. Roots seek moisture and grow into small cracks in clay or cast iron pipes, eventually filling and breaking the line entirely.

Trenchless relining works well when the existing pipe retains its general shape. Severely collapsed sections or extreme offset joints may require excavation. We always recommend the most appropriate method after seeing the camera footage.

Trenchless repair can often be completed in one day. A full excavation and replacement typically takes 2–3 days. We'll give you a precise timeline along with your upfront quote.
