How the damage is found
Almost every repair quote starts with a camera. The plumber clears the line, pushes a camera from the cleanout toward the street and records it. A locator in the camera head lets them mark the yard above each defect and measure its depth. The recording shows what failed: roots at joints, a crack, a joint that has shifted, a sagging section that holds water, or pipe that has collapsed or deformed. Our page on sewer camera inspection explains how to read that footage.
Three repair methods compared
| Method | How it works | Fits | Fixr, per foot |
|---|---|---|---|
| Dig and replace | Excavate over the pipe, cut out the damaged run, lay new PVC | Short runs, shallow pipe, collapsed sections, sags that need regrading | $50–$250 |
| Lining (cured in place) | A resin-soaked tube is inverted into the old pipe and cured into a new pipe inside it | Cracked or root-damaged pipe that still holds its shape | $50–$250 |
| Pipe bursting | A bursting head splits the old pipe and pulls new plastic pipe behind it, between two small pits | Long runs under driveways, lawns and trees; pipe too damaged to line | $50–$200 |
Source: Fixr, Drain Line Breakage Repair Cost, updated January 31, 2025. Fixr describes most repairs of a broken drain line at $400 to $1,500, around $600 typical, and notes its figures cover drain lines in general, the sewer lateral among them.
Lining can't fix a pipe that has lost its shape, and it doesn't correct a sag: the liner follows the old pipe's path, dip included. Bursting replaces the pipe along the same route and can upsize it, but it needs access pits at both ends and can be limited by nearby utility lines. Digging is the only way to regrade a section.
What drives the price
- Length and depth. Per-foot pricing multiplies quickly, and a deep lateral needs a wider, shored trench.
- What sits above it. Concrete, pavers, mature trees and finished basements change both the method and the restoration bill.
- Where the damage is. A repair in the street or at the city main may need a street-opening permit and traffic control.
- Added cleanouts. A two-way cleanout near the house often goes in during the repair and pays for itself at the next clog.
- Permits. Most cities require a permit and an inspection for sewer lateral work.
Who is responsible for the sewer line?
There is no single national rule. In many cities the property owner is responsible for the whole lateral, from the house to the connection at the public main, even the part under the street. In others the city takes over at the property line or at a cleanout near the curb. Your city's sewer or public works department can tell you where its responsibility starts, and it's worth asking before you get quotes, because it decides who pays for a street repair.
Pipe materials you may find
The camera usually identifies the pipe. Vitrified clay, common in older neighborhoods, is durable but has joints every few feet where roots get in. Cast iron corrodes from the inside and cracks along its length. Fiber pipe known as Orangeburg, laid in many postwar houses, softens and flattens with age. Modern laterals are PVC or ABS with glued joints, and the repair pipe is almost always one of those.
Questions to ask before approving the repair
- Can I have a copy of the camera recording, with the distance to each defect?
- Which method, over how many feet, and why that one?
- Is restoration included: yard, driveway, sidewalk?
- Who pulls the permit, and is a street-opening permit needed?
- What is the warranty on the pipe and on the labor?
If the problem turns out to be grease or scale rather than damage, repair isn't needed at all. Hydro jetting or routine drain cleaning may be the right quote.
Before you approve a sewer repair
How long does a trenchless repair take?
Many residential lining and bursting jobs are finished in a day or two once permits are issued and the line has been cleaned and filmed. Open-trench work takes longer, mostly because of digging and restoring the yard or driveway.
Does a liner make the pipe smaller?
Slightly. The cured liner adds a wall inside the old pipe. In a typical house lateral the loss is small, and the smooth, jointless surface usually carries flow better than the rough old pipe did.
Will homeowners insurance pay for a broken sewer line?
Standard policies commonly exclude wear, tree roots and gradual deterioration. Some insurers and utilities sell service line coverage as an add-on. Read the exclusions before the work starts, not after.
Can roots grow back through a liner?
Not through the liner itself, which has no joints for roots to enter. They can still reach the line where the liner ends or where branch connections meet it, so ask how those points are sealed.
