Most homeowners pay $2,000–$12,000 for trenchless sewer line replacement, or about $60–$250 per linear foot. Angi puts the average job at about $2,900, while long laterals and lined runs under driveways land near the top of the range (Angi, HomeGuide and Forbes Home data, as of October 2026).

Trenchless replacement fixes a broken sewer lateral through one or two small access pits instead of a trench along the whole line. It makes the most sense when the pipe runs under a driveway, mature trees, a patio or landscaping you don't want torn up.
This page compares pipe bursting and cured-in-place lining, shows what drives the price and explains how to compare quotes. For open-trench prices and the full picture, see our sewer line replacement cost guide.
Average cost
Installed trenchless prices for residential sewer laterals, national averages as of October 2026:
| Scenario | Typical range | Notes |
|---|---|---|
| Short lateral, 25–35 feet | $1,500–$8,750 | Often one access pit plus the cleanout |
| Typical lateral, 45–55 feet | $2,700–$13,750 | Most common house-to-street run |
| Long lateral, 75–100 feet | $4,500–$25,000 | Long pulls, more setup time and larger pits |
Pipe bursting vs. cured-in-place lining
| Method | Cost per linear foot | Best for |
|---|---|---|
| Pipe bursting | $60–$200 | Badly cracked or undersized pipe; installs a brand-new pipe |
| Cured-in-place lining (CIPP) | $90–$250 | Pipe still holds its shape; minimal digging |
| Spin-cast lining | $80–$250 | Coating the inside of the existing pipe |
| Traditional trench (for comparison) | $50–$200 | Plus yard, driveway and landscaping restoration |
Cost breakdown: materials, labor, permits and extras
Line-item estimate for replacing a 50-foot house-to-street lateral by pipe bursting, with two access pits. Ranges are national, as of October 8, 2026.
| Cost item | Typical range | What it covers |
|---|---|---|
| Trenchless replacement (pipe, equipment, labor) | $3,000–$10,000 | About $60–$200 per linear foot |
| Access pit excavation | $200–$1,000 | WhatHomeCosts estimate: a few hours of extra labor at $60–$250 per hour |
| Camera inspection | $175–$350 | Before the job, to confirm the method and length |
| Permits & inspections | $100–$1,000 | Up to about $1,000 depending on the city |
| Contingency (about 10%) | $200–$1,000 | Collapsed sections, roots or a hard tie-in at the main |
| Estimated total | $3,700–$13,500 | Before any discounts or rebates |
Most of the cost is the per-foot trenchless work; the savings come from the restoration you no longer need.
What affects the price
- Pipe length and diameter. Trenchless work is priced per foot, so length drives the total: Angi reports about $1,500–$8,750 for 25–35 feet and up to $25,000 for 75–100 feet. Larger-diameter pipe needs bigger equipment and costs more to burst or line.
- Method (pipe bursting or cured-in-place lining). Pipe bursting runs about $60–$200 per foot and installs a new pipe; cured-in-place lining runs $90–$250 per foot and creates a new pipe inside the old one.
- Condition of the existing pipe. Lining needs a pipe that still holds its shape. Collapsed, severely offset or heavily root-filled sections may need hydro jetting first, a short trench repair, or pipe bursting instead.
- Number and size of access pits. Most jobs need one or two pits; each extra pit, deeper pit or tie-in adds labor billed at about $60–$250 per hour, and tie-ins can run $60–$250 per linear foot.
- Camera inspection before the job. A camera inspection ($175–$350 on Angi's figures) is needed to measure the line and confirm the pipe is a candidate for trenchless repair.
- Local permit rules. Permit fees can reach about $1,000, and some cities restrict lining or require inspections at the tie-in to the main.
Ways to save
- Ask each contractor to quote both pipe bursting and lining. Depending on the pipe's condition, one method can be thousands cheaper.
- Compare the trenchless quote with an open-trench quote that includes full restoration. If the line runs under lawn only, digging may be cheaper.
- Reuse an existing camera video if it is recent, and ask whether the contractor's own inspection fee is credited toward the job.
- Line only the damaged section if the rest of the pipe is in good shape. Spot or partial lining costs less than a full run.
- Ask your city about sewer lateral cost-sharing programs and your insurer about service-line coverage before you sign.
- Get at least three itemized quotes that state the length, pipe or liner material, number of pits and warranty.
How to get an accurate quote
Request written quotes from at least three licensed contractors that offer trenchless work. Share the same details with each:
- The camera inspection video, the total length of the line and the pipe material and diameter.
- Where the cleanouts are and what sits above the line (driveway, trees, patio, sidewalk).
- Which method you want priced (pipe bursting, lining or both) and how many access pits they expect to dig.
- Ask about permits, the tie-in to the city main, restoration of the pits and the warranty on the new pipe or liner.
FAQ
Is trenchless sewer replacement cheaper than digging?
Not always per foot, but often overall. Forbes Home puts trenchless jobs at about $3,000–$12,000 versus $4,000–$20,000 for traditional digging, because you skip most landscaping and hardscape restoration.
How long does a trenchless sewer line last?
New lining and pipe materials can last more than 50 years, according to Forbes Home. Warranty terms vary by contractor and product.
Can every sewer line be replaced without digging?
No. Collapsed pipes, sharp bends, sags and some connections may still need a trench repair. A camera inspection tells the contractor which method will work.
