- Per-foot pricing: Pipe bursting averages $125 per foot, and CIPP lining averages $150 per foot.
- Total job range: Most homeowners pay between $1,000 and $20,000, depending on length and pipe condition.

What makes trenchless sewer replacement cost more or less?
The final price moves within the $50-$250 per-foot range based on what's under your yard and inside your pipe. Length is the biggest driver, but access, pipe material, and whether a cleanout already exists can push you toward the high end.
- Pipe length: Longer sewer laterals add more linear feet. Most residential laterals fall between 50 and 80 feet.
- Access: If the pipe runs under a driveway or slab, the contractor needs to dig deeper access pits, adds complexity but no separate cost per foot.
- Depth: Once your line sits 6 feet or deeper, safety requirements may slow work, but depth itself does not add a line item to your bill.
- Old pipe material: Cast iron or clay pipes can be harder to burst, leaning your quote toward the $200 per-foot end.
- Obstructions like tree roots may require extra steps before lining, but a camera inspection catches them first.
- Always check the trenchless vs. dig decision tool once you know your pipe condition.
Pipe bursting vs. CIPP lining: How much does each method cost?
Both trenchless methods keep your yard intact, but they work differently. Pipe bursting pulls a new pipe through the old one, while CIPP lining cures a resin liner inside the existing pipe.
- Pipe bursting: $50-$200 per foot, typical $125. Works best when the old pipe is collapsed or needs a full replacement.
- CIPP lining: $50-$250 per foot, typical $150. Ideal when the pipe walls are structurally sound but have cracks, roots, or leaks.
- Spot repair: $400-$1,500 (5-10 foot section). Only fixes one short damaged spot.
- Camera inspection ($100-$500) always comes first; a contractor cannot quote a method without seeing inside the pipe.

What mistakes do people make when hiring for trenchless replacement?
A few wrong moves can add thousands to your bill or leave you with a bad pipe. Knowing them ahead of time keeps the project affordable and permanent.
- Skipping the camera inspection: No honest plumber quotes trenchless work blind. Insist on a recording and a written report.
- Not reading the fine print: Some quotes include landscape repair, others do not; confirm what “restoration” means.
- Choosing based on the lowest bid: A too-cheap price often means shorter training or no warranty.
- Ignoring the permit: Sewer work usually needs a local permit. Always confirm with your building department.
- Assuming trenchless works everywhere: Only a camera inspection can decide; our trenchless vs. dig decision tool explains why.
Trenchless or dig it up: How does the choice break down?
You do not make this call from a brochure. A camera inspection gives your plumber the information to recommend one or the other. Compare what matters below.
- Yard damage: Trenchless needs only two small pits; open trench tears up the entire line.
- Speed: Trenchless often finishes in one day; dig-ups take longer.
- Pipe upgrade: Pipe bursting can increase pipe diameter; CIPP slightly reduces it.
- Cost: Trenchless and open trench have similar per-foot ranges, but restoration costs can make digging more expensive overall.
- Use the trenchless vs. dig decision tool to see which factor fits your situation.
When should you call a professional for sewer line replacement?
All trenchless sewer replacement is professional work. You need a licensed plumber with trenchless equipment. Do not attempt any digging yourself; call 811 before any excavation: hitting a buried utility line can be deadly.

- Sewage odor or wet spots in the yard: These signal a leaking or separated pipe.
- Old pipe material: If your home has clay, cast iron, or Orangeburg, the pipe may be near end of life.
- Tree root intrusion seen on camera: Roots will grow back unless the pipe is replaced.
- Get 2-3 quotes from licensed contractors who have done trenchless work in your area. Our sewer repair cost calculator gives you a reference range to weigh against those quotes.
