Sewer Line Replacement Cost: Per Foot in 2026
Estimate sewer line replacement cost per linear foot — with the free calculator.
A failed sewer line is the most stressful home repair there is — but the cost is predictable once you know the per-foot range and the trenchless option.
THE SHORT ANSWER
The short answer
Sewer line replacement runs $50–$250 per linear foot installed in 2026, averaging $150/ft. A typical 100 ft replacement runs $5,000–$15,000. Trenchless (CIPP lining) runs $90–$250 per foot.
What it costs
Traditional trench replacement runs $50–$250 per foot. Trenchless pipe bursting runs $60–$250. CIPP lining (no dig, repairs in place) runs $90–$250. Trenching alone adds $5–$12 per foot on top.
- Traditional dig: $50–$250 per ft
- Pipe bursting (trenchless): $60–$250 per ft
- CIPP lining: $90–$250 per ft
- Typical 100 ft job: $5,000–$15,000
Trenchless vs dig
Trenchless costs more per foot but saves landscaping, driveways and time. CIPP lining is ideal when the pipe is structurally sound but leaking. Digging is cheaper for short runs or when the pipe has collapsed.
