What Does Sewer Line Replacement Cost in Dallas County?
Real price ranges for spot repair, lining and full replacement in Dallas County, plus what drives the number up.
Typical ranges
Spot repairs on a single joint commonly run $1,500–$4,000. Trenchless lining of a 50–80 ft lateral often lands between $6,000 and $14,000. Full open-trench replacement ranges $4,000–$12,000 depending on depth and surface restoration, and under-slab tunneling adds per-foot costs.
What moves the price
Depth to the city main, length of run, whether the line crosses a driveway or mature tree, the City of Dallas permit and inspection, and whether a new cleanout is required.
Who pays for what
Dallas Water Utilities maintains the public main; the homeowner owns the lateral from the house to the connection. Confirm the tap location before budgeting.
If your scope shows a full-length failure, replacing the whole lateral is usually cheaper than repeated spot fixes.
