Trenchless sewer repair cost (2026)

By USA Expert Plumbing Editorial Team. Updated . 2 min read.

Short answer

Trenchless sewer repair typically costs about $60 to $250 per linear foot in 2026, or roughly $3,500 to $20,000 for a typical home. Angi puts pipe lining at about $135 to $150 per foot and pipe bursting at about $150 to $190 per foot. Trenchless costs more per foot than digging but saves on yard and driveway restoration.

Trenchless sewer repair fixes or replaces a sewer line through small access holes instead of a long trench. It is popular because it leaves lawns, driveways and landscaping mostly intact.

Figures are 2026 national estimates compiled from published cost guides such as Angi, HomeGuide and This Old House. Prices in high-cost metro areas often run above these ranges.

The two main methods

Pipe lining (CIPP)

A resin-soaked liner is pulled or blown into the old pipe and cured in place, creating a new pipe inside the old one. It works when the existing pipe is cracked, leaking or has root intrusion but still holds its shape.

Pipe bursting

A bursting head is pulled through the old pipe, breaking it apart while pulling a new pipe in behind it. It is a full replacement and can even increase the pipe diameter.

What affects the price

  • Length and diameter of the line.
  • Pipe condition. Lining needs a pipe that is not collapsed; heavily damaged lines may need cleaning and spot repairs first.
  • Access. Each method needs an entry and exit point, such as a cleanout or small pit.
  • Bends and connections. Sharp turns and branch lines add complexity.
  • Local permits and required inspections.

When trenchless does not work

A fully collapsed pipe, a severe belly (a sag that holds water) or a line with many sharp bends may still need traditional excavation. A camera inspection before the quote tells you which options are realistic.

The real comparison

Compare the full cost, not the per-foot price. Traditional digging is cheaper per foot, but restoring a lawn, patio or concrete driveway afterward can add thousands. Our sewer line replacement cost guide walks through the traditional side of that comparison.

How to compare quotes

  • Get at least two or three written quotes for the same scope of work.
  • Ask what is included: permits, inspections, cleanup, and any wall, floor or yard restoration.
  • Ask about the warranty on both parts and labor.
  • Be wary of a quote far below the others and ask what it leaves out.

Common questions

Is trenchless sewer repair worth it?

It usually is when the line runs under a driveway, patio or mature landscaping, because it avoids expensive restoration. For a short line under open lawn, digging can be cheaper.

How long does a sewer pipe liner last?

Manufacturers commonly rate cured-in-place liners for several decades. Ask the contractor for the product warranty in writing.
