Sewer Line Repair vs. Replacement
A damaged sewer line can sometimes be fixed in one spot; other times the whole line needs to go. HomeAdvisor puts typical sewer line work at $1,388–$5,323, averaging about $3,319.
Start with a camera inspection
A sewer camera inspection ($100–$500) shows roots, cracks, sags (bellies), offset joints and collapsed sections. Ask for the video and a written description with the distance to each problem.
Repair or replace?
| Camera finding | Usually means |
|---|---|
| One root intrusion or crack in an otherwise good pipe | Spot repair (about $50 per linear ft. for a partial replacement) |
| A single sag holding water | Spot repair if accessible |
| Roots and cracks in many places | Replacement or lining |
| Old clay, cast iron or Orangeburg pipe failing throughout | Replacement |
| Collapsed section | Excavation at that point; trenchless lining will not work through a full collapse |
From HomeAdvisor's sewer line cost guide.
Replacement costs
| Method | Typical cost per linear ft. |
|---|---|
| Traditional complete replacement | $60–$250 |
| Trenchless pipe lining (CIPP) | $90–$250 |
| Trenchless pipe bursting | $60–$200 |
| Line under a slab | Adds $300–$350 per ft. |
| Landscape, driveway or patio repair afterward | $1–$25 per sq. ft. |
From HomeAdvisor. See trenchless vs. traditional excavation.
Who pays for what
Homeowners are usually responsible for the line from the house to the property line or the city main; the exact point varies by city. Ask your utility, and check whether your homeowners policy or a service line warranty covers sewer lines.
