Sewer Line Replacement Cost Calculator
Sewer line replacement is priced per foot of pipe, and the method (digging a trench or going trenchless) changes the total. Enter the pipe length to estimate.

What drives the price
- MethodTrenching is often cheapest per foot but tears up the yard. Trenchless methods cost similar or more per foot and avoid most restoration.
- Depth and lengthDeeper and longer lines take more digging or more pipe.
- What's in the wayDriveways, mature trees and patios over the line raise excavation and restoration costs.
- City connectionSome jobs include work at the street tap, which can require extra permits and fees.
How this estimate works
The calculator multiplies your pipe length by the installed price range for the option you pick, then adds any extras you tick and typical permit and mobilization. The headline number is the midpoint of your range. Low-end prices fit simple jobs in lower-cost areas. High-end prices fit complex jobs, premium brands and high-cost metros.
Get at least three written quotes before you hire. Ask each contractor to list materials, labor, permits and disposal separately so you can compare them line by line. Read how we build our ranges.
Common questions
How do I know if my sewer line needs replacing?
Recurring backups, gurgling drains and soggy patches in the yard are common signs. A camera inspection confirms it.
Is the sewer line my responsibility?
In many areas the homeowner owns the line from the house to the street connection. Check with your local utility.
Does homeowners insurance cover sewer lines?
Standard policies often exclude it, but some offer an add-on endorsement. Check your own policy.
