Sewer line replacement cost averages about $3,319 nationally, and most homeowners pay between $1,388 and $5,323. Short spot repairs cost less, while long, deep lines under driveways cost more. Our sewer repair team in High Point quotes the exact price before any digging starts.
A failing sewer line is not a job you can put off for long. Slow drains turn into backups, and backups turn into cleanup bills. This guide breaks down what you will actually pay, what drives the number and how to spot trouble early.
Key Takeaways: Sewer Line Replacement Cost
- Average cost: about $3,319, with most jobs between $1,388 and $5,323.
- Per foot: complete replacement and burst pipe work run about $60 to $250 per linear foot.
- Inspect first: a video inspection runs about $100 to $500 and shows the exact problem.
- Trenchless can save yards: less digging often means less restoration cost.
- Warning signs: gurgling drains, sewage smells and soggy spots in the yard.
What Is the Average Sewer Line Replacement Cost?
According to Angi’s 2026 sewer cost data, the national average is $3,319. Most projects land between $1,388 and $5,323, with a full range of $225 to $10,000.
That wide spread comes from the size of the job. Fixing one cracked joint is a very different project from replacing 80 feet of clay pipe that runs under a driveway.
What Is Usually Included
- A camera inspection to find the damage
- Locating and marking the line
- Excavation or trenchless access points
- New pipe and fittings
- Permits and a final test
- Backfill, with restoration quoted separately
Sewer Line Replacement Cost by Method
How the line gets replaced changes the price a lot. Here is how the main options compare.
| Method | How It Works | Best For |
|---|---|---|
| Spot repair | Dig and replace only the broken section | One crack, sag or root entry point |
| Open trench replacement | Dig along the full line and lay new pipe | Collapsed or badly sagging lines |
| Trenchless pipe bursting | Pull new pipe through the old one, breaking it outward | Lines under driveways, trees or landscaping |
| Trenchless pipe lining | Cure a resin liner inside the old pipe | Cracked pipe that still holds its shape |
Angi reports complete replacement and burst pipe work at roughly $60 to $250 per linear foot, and a partial replacement is usually the most affordable option.
Open Trench vs Trenchless
Open trench work often costs less per foot, but it tears up lawns, walkways and plantings. Trenchless work can cost more per foot, yet it can save money once you count yard and driveway restoration. Our plumbing excavation services cover both approaches.
6 Factors That Change the Price
Two homes with the same problem can get very different quotes. These six factors explain most of the difference.
- Length of the line. More feet means more pipe and more labor.
- Depth. Deeper lines need more digging and shoring.
- What sits on top. Driveways, patios and mature trees raise the cost.
- Pipe material. PVC is common and affordable, while other materials cost more.
- Replacement method. Spot repair, open trench and trenchless all price differently.
- Permits and restoration. City permits, inspections and yard repair add to the total.
At All-Star Plumbing, you approve the full price first, and there is no charge if you decline the quote. For larger jobs, our plumbing financing page explains Wisetack plans from $500 to $25,000.
Signs You Need a New Sewer Line
Sewer problems rarely stay small. Watch for these warning signs around your home.
- Several slow drains at the same time
- Gurgling toilets or tubs after you run water
- Sewage smell inside or in the yard
- Soggy, green patches over the sewer line
- Repeat backups even after cleaning
- Cracks or settling in the slab or foundation
Blockages and line breaks cause real damage beyond one house. The EPA sanitary sewer overflow page estimates 23,000 to 75,000 sewer overflows happen in the U.S. each year, not counting backups into buildings. If sewage is already coming up, call our sewer backup emergency service right away.
Repair or Replace the Whole Sewer Line?
A drain camera inspection service answers this question fast. It shows whether the damage is in one spot or spread along the whole line.
When a Repair Makes Sense
- One crack, offset joint or root entry point
- The rest of the pipe is in good shape
- The line is fairly new
When Replacement Makes Sense
- The pipe has collapsed or bellied in several places
- Roots have entered at many joints
- Old clay or cast iron is cracking along its length
- You keep paying for repeat repairs
Routine cleaning can buy time on a healthy line. Our guide on sewer cleanout costs covers that side of the budget.
Frequently Asked Questions
What is the cheapest way to replace a sewer line?
A spot repair of only the damaged section usually costs the least. When the whole line is failing, trenchless methods can lower the total by cutting down on digging and yard repair.
Is replacing a sewer line expensive?
It can be. Angi puts the national average at $3,319, with most jobs between $1,388 and $5,323. Long runs, deep lines and driveway crossings push the price higher.
Does homeowners insurance cover sewer lines?
Standard policies often exclude sewer lines damaged by age, wear or tree roots. Some insurers sell a service line endorsement. Check your policy and ask your agent before work starts.
Can a sewer line be replaced without digging?
Often, yes. Trenchless pipe bursting or pipe lining needs only small access holes. It does not fit every line, so a camera inspection comes first.
