A failing sewer line is one of the least visible and most stressful home repairs — and one of the more expensive. Replacement runs $3,000 to $12,000 in 2026, averaging around $5,500, or about $50–$250 per linear foot depending on method and access.
What you’re paying for
The pipe is cheap; the work is in getting to it. Your cost covers excavation or trenchless equipment, labor, a camera inspection to locate the problem, permits, and — often the biggest surprise — restoring whatever sits on top of the line: lawn, landscaping, walkways, or driveway.
Trenchless vs. dig-and-replace
The method drives both price and disruption. Traditional dig-and-replace is cheaper per foot but excavates a trench across your property. Trenchless methods (pipe lining or pipe bursting) cost more per foot but require only small access pits — far less damage to a finished yard or driveway, which can make trenchless cheaper overall once restoration is factored in.
Get a camera inspection first
Before approving a full replacement, pay for a camera inspection ($200–$500). It shows exactly where and how bad the problem is — sometimes a spot repair or cleaning solves it, saving thousands versus a full replacement.
How to save on sewer line work
- Start with a camera inspection to confirm the scope.
- Compare trenchless and traditional bids including restoration.
- Check for a service-line insurance endorsement before you need it.
- Act on early warning signs before a full collapse forces an emergency dig.

What affects the price
- Line length Sewer lines are priced per foot; a long run to the street costs more.
- Depth & access Deeper lines and tight access raise excavation costs.
- Method Trenchless lining or pipe bursting costs more per foot but spares your yard and hardscape.
- Location Lines under driveways, slabs, or mature landscaping add demolition and restoration costs.
- Material PVC is the budget-friendly standard; older cast iron or clay is what's usually being replaced.
Frequently asked questions
- How much does sewer line replacement cost per foot?
- It runs $50–$250 per linear foot installed, averaging around $150. Lines under a slab or driveway can reach $300–$350 per foot once demo and restoration are added.
- Trenchless vs. traditional — which is better?
- Trenchless (lining or pipe bursting) costs more per foot but avoids digging a trench across your yard. Traditional dig-and-replace is cheaper per foot but tears up everything above the line.
- Is my sewer line my responsibility or the city's?
- The lateral line from your home to the city main is almost always the homeowner's responsibility; the city maintains the main itself. Check local rules.
- What are the signs of a failing sewer line?
- Frequent backups, slow drains throughout the house, sewage smells, soggy patches in the yard, and gurgling toilets all point to a sewer problem.
- Does insurance cover sewer line replacement?
- Standard policies usually exclude it, but a 'service line' add-on or endorsement can cover it. Check your policy before you need it.
- How long does it take?
- Trenchless jobs can finish in a day; traditional excavation and restoration may take 3–5 days depending on length and access.
