Trenchless sewer repair prices are driven by one number more than any other: the length of pipe being renewed. In 2026, most trenchless work in the Southwest and West Coast falls between $60 and $250 per foot, with a typical residential lateral (30–60 feet) landing between $4,000 and $15,000 all-in.
| Method | Typical range (per foot) | Typical residential job |
|---|---|---|
| CIPP lining (cured-in-place pipe) | $80 – $250 | $4,000 – $15,000 |
| Pipe bursting (full replacement) | $60 – $200 | $3,500 – $12,000 |
| Sectional / spot repair | $600 – $2,500 per section | $1,000 – $4,000 |
| Traditional excavation (for comparison) | $50 – $250 + restoration | $4,000 – $25,000+ with restoration |
The number excavation quotes hide: restoration. Repouring a driveway, re-landscaping a yard, or replacing interior flooring after a slab cut routinely adds $2,000–$10,000 that never appears on the dig quote. Trenchless methods work through two small access points, so that line item mostly disappears.
Pipe bursting is often slightly cheaper per foot and delivers a brand-new full-diameter pipe, but it needs room to pull a new pipe through — read the full comparison in our pipe bursting vs. pipe lining guide. CIPP lining shines when the old pipe is structurally intact but leaking, cracked, or root-invaded, and it handles bends well. Learn what's involved in each on our services page.
Any quote given without a camera inspection is a guess. The real process: a camera inspection locates the damage and measures the line, then a specialist quotes the correct method for your pipe's condition. Most of our listed providers apply the inspection cost toward the repair.

Per foot, trenchless methods can look similar to open-cut excavation. But once you add the cost of tearing out and restoring driveways, landscaping, patios, or flooring — which excavation requires and trenchless avoids — the total project cost of trenchless is frequently equal or lower.
Under-slab lining usually stays in the same $80–$250 per foot range as yard laterals, and the savings are dramatic compared to cutting the slab: no jackhammering, no flooring replacement, no weeks of interior restoration.
Usually not for wear-and-age failures, which most are. Some policies or service-line riders cover sudden damage. It's always worth a call to your insurer, and a camera-inspection report gives you documentation either way.
Yes — sectional (spot) liners target a single failed joint or crack and can cost a fraction of a full-line job. A camera inspection determines whether a spot repair will actually solve the problem or just move it.
CIPP (cured-in-place pipe) lining costs $80–$250 per foot in 2026 — most homes pay $4,000–$15,000 for a fully relined lateral that's warrantied for decades.
