Sewer Line Replacement Cost in 2026
Sewer line replacement costs $3,000 to $15,000 for most homeowners, averaging about $7,500 — but the repair method matters more than anything else. A spot repair on one damaged section can run $1,500, while trenching the same line under a slab runs five figures. Sewer line repair (a spot fix) and trenchless sewer repair sit at very different points on that scale.
Trenchless methods — CIPP lining ($125–$200 per foot) and pipe bursting ($60–$200 per foot) — often cost more per foot than open-trench but save $2,000–$5,000 all-in once you count the surface restoration digging avoids. Which method your line qualifies for depends entirely on what a camera finds.
Sewer Line Repair Pros connects you with independent local sewer pros who run a camera before quoting. The ranges below are honest 2026 national figures from Angi, HomeGuide, and HomeAdvisor — only a camera-verified bid is exact.
Typical national range
$3,000 – $15,000
Complete replacements average about $7,500. Spot repairs start near $1,500; local labor and depth move quotes ±40%.

Cost breakdown
| Item | Typical range | Notes |
|---|---|---|
| Spot repair (one damaged section) | $1,500 – $4,000 | Only an option if the rest of the pipe is sound. |
| CIPP pipe lining (trenchless) | $125 – $200 | Per foot; full runs commonly $6,500–$12,000. Needs a structurally intact host pipe. |
| Pipe bursting (trenchless) | $60 – $200 | Per foot; full jobs commonly $8,000–$15,000. Handles badly deteriorated pipe; needs two access pits. |
| Open-trench replacement | $50 – $250 | Per foot; pipe work $50–$125/LF plus excavation $50–$200/LF. Add surface restoration. |
| Open-cut under slab | $300 – $350 | Per foot; concrete breakout, hand digging, and re-pour ride along. |
| Driveway / concrete restoration | $2,000 – $4,000 | Trenchless methods avoid most of this. |
| Camera inspection | $125 – $500 | The first dollar to spend; decides which methods your line qualifies for. |
| Slab leak repair (related plumbing) | $2,000 – $6,000 | A leak in a line under the slab; access is the expensive part, which trenchless spot repair can avoid. |
What changes the price
Providers quote their own work — these are the factors that consistently move the number.
- Repair method: a spot repair runs $1,500–$4,000, while a full replacement by lining, bursting, or open trench runs into five figures — the camera decides which methods are even possible.
- Line length: laterals from the house to the street are typically 30–80 ft, and per-foot methods scale directly with that footage.
- What's above the line: open-cutting under a driveway adds $2,000+ in restoration and under a slab runs $300–$350/LF, which is where trenchless usually wins.
- Pipe condition: a collapsed or badly bellied line can't be lined and needs bursting or a full dig; a single crack may only need a spot repair.
- Depth: trenches deeper than 6 ft need shoring and bigger equipment, adding $500–$2,500.
- Local labor, soil, and permits: these move quotes by ±40% on the same length of pipe, which is why camera-verified bids are the only exact number.
Repair or replace?
Trenchless vs open-trench is the core decision. Per foot, trenchless lining and bursting often cost more than digging — but all-in they typically save $2,000–$5,000 (30–50%) once excavation and restoration are counted, especially under driveways, mature landscaping, or a slab. Over open lawn with a shallow line, a straight dig can still be the cheapest option.
Whether your line qualifies for trenchless comes down to pipe condition, which only a camera can confirm. Our trenchless sewer repair candidacy tool walks through the factors that decide lining vs bursting vs dig — try it at /tools/trenchless-sewer-repair-candidacy before you collect bids.
Frequently Asked Questions
How much does it cost to replace 50 feet of sewer line?
Roughly $2,500–$12,500 by open trench ($50–$250/LF), $6,250–$10,000 by CIPP lining ($125–$200/LF typical), or $3,000–$10,000 by pipe bursting ($60–$200/LF) — before surface restoration. Under a driveway or slab, trenchless usually comes out cheaper once you count the concrete work an open trench requires.
How much does trenchless sewer repair cost?
Trenchless CIPP lining runs $125–$200 per foot (quotes range $80–$250/LF by diameter), and pipe bursting runs $60–$200 per foot. Full trenchless jobs commonly land at $6,500–$15,000. Per foot it often costs more than digging, but it typically saves $2,000–$5,000 all-in by avoiding surface restoration.
Is trenchless sewer replacement cheaper than digging?
Per foot, trenchless often costs more — but all-in it typically saves $2,000–$5,000 (30–50%) once excavation and restoration are counted, especially under driveways, mature landscaping, or a slab. Over open lawn with a shallow line, a straight dig can still be the cheapest option.
How much does slab leak repair cost?
A slab leak — a leak in a pipe running under the home's concrete slab — typically runs $2,000–$6,000, because the expensive part is accessing the line. Where the failure is on the sewer lateral, a trenchless spot repair can avoid breaking the slab entirely; a camera inspection confirms the location and method first.
Why do quotes for the same job vary so much?
Depth, soil, local labor rates, permit costs, and how much surface has to be restored all vary by property and market — easily ±40% on the same length of pipe. Get at least two camera-verified bids, and make sure each one states the method, footage, depth, and restoration scope in writing.
