Sewer line replacement cost (2026)

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

Short answer

Most sewer line replacements cost about $50 to $250 per linear foot in 2026. For a typical residential line of 50 to 100 feet, that works out to roughly $3,000 to $20,000 installed. Depth, length, the replacement method and what sits on top of the line, such as a driveway, drive the price.

Replacing the main sewer line, the pipe that carries waste from your house to the city sewer, is one of the bigger plumbing bills a homeowner can face. The price swings widely because every line is a different length and depth, and some run under lawns while others run under driveways and trees.

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.

Typical cost by method

MethodTypical cost per footBest for
Traditional excavation (open trench)About $50 to $125Collapsed pipe, severe sags, short runs under lawn
Pipe bursting (trenchless)About $60 to $200Full replacement with access pits at each end
Pipe lining / CIPP (trenchless)About $80 to $250Cracked or root-damaged pipe that still holds its shape

For a typical home, the total usually lands between about $3,000 and $20,000. Short, shallow, easy-access lines sit near the bottom; long, deep lines under concrete sit at the top or above it.

What raises the price

  • Length and depth. Deeper lines need more excavation, shoring and time.
  • What is on top. Breaking and repouring a driveway, patio or sidewalk can add thousands.
  • Trees. Roots near the line add labor, and the tree may need protection or removal.
  • Permits and inspections. Many cities require them; fees range from about $100 to $1,000.
  • Street-side work. Connecting in the street can require extra permits and traffic control.
  • Cleanouts. Adding a cleanout for future access is a common, worthwhile add-on.

Start with a camera inspection

A sewer camera inspection shows whether the whole line has failed or just one section. If only a few feet are broken, a spot repair, often around $1,500 to $4,000, may be enough. Ask to see the video before you agree to full replacement.

Traditional or trenchless?

Trenchless methods often cost more per foot but avoid tearing up the yard, so the total can come out close to, or below, a dig-and-replace job once restoration is counted. Trenchless is not always possible: a fully collapsed pipe cannot be lined, and pipe bursting needs a reasonably straight path.

Who pays

In most U.S. cities, the homeowner is responsible for the sewer lateral from the house to the city main or to the property line. Rules vary, so check with your city before work begins.

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

How much does it cost to replace 50 feet of sewer line?

At $50 to $250 per foot, a 50-foot line typically costs about $2,500 to $12,500 before restoration, permits and extras. Trenchless jobs of that length often land around $6,000 to $15,000.

Does homeowners insurance pay for sewer line replacement?

Standard policies usually exclude wear, tree roots and corrosion. Some insurers offer a service line endorsement for a small monthly cost.

How long does sewer line replacement take?

Many trenchless jobs finish in one or two days. Traditional excavation can take several days, plus time for inspection and restoration.
