The answer to 'average cost of sewer line' is that the typical range for sewer line replacement or repair can vary widely depending on several key factors. In general, homeowners can expect to pay anywhere from $3,000 to $15,000 or more for a sewer line project, with the average cost falling around $7,000 to $10,000.
The biggest influences on sewer line costs are the length and depth of the pipe, the material it's made from, whether the line needs to be dug up or can be repaired using trenchless methods, and the complexity of the job due to the home's location or surrounding landscaping. Costs are also affected by your local labor rates, permit fees, and disposal fees.
