Sewer Line Repair Cost Guide

A trenchless spot repair (CIPP lining) typically costs $1,500–$4,000. A full sewer line replacement costs $3,500–$12,000 depending on length, depth, access, and method. Open trench replacements on deep or long lines with difficult access and concrete restoration can exceed $12,000.

Trenchless methods (pipe lining or pipe bursting) repair or replace the sewer line with minimal excavation - typically just small access pits at each end. Open trench requires digging along the full length of the pipe. Trenchless is less disruptive to landscaping and hardscape but is not always an option, depending on pipe condition and access.

Yes, in almost every case. A camera inspection identifies the exact problem (root intrusion, pipe belly, crack, offset joint) and its location. Recommending a full sewer replacement without a camera inspection is a red flag - it may be diagnosing a $400 hydro-jet cleaning as a $6,000 replacement job.

Yes. Sewer line repair and replacement requires a permit in virtually every US jurisdiction. The permit triggers an inspection to confirm the work meets code. A contractor who skips the permit is working without oversight - do not accept this.

In most jurisdictions, the homeowner is responsible for the sewer lateral - the pipe that runs from your home to the city sewer main. The city is responsible for the main sewer line. The property line is typically the boundary, but this varies by municipality. Your contractor should clarify exactly what section of pipe is being addressed.
