The answer to 'how much does sewer line cost' is that the cost can vary significantly depending on several factors. Sewer line repair and replacement projects typically range from a few hundred dollars for minor fixes to tens of thousands for major overhauls.
The key factors that influence the cost include the length of the sewer line, the material and condition of the existing pipes, the depth and accessibility of the line, the complexity of the job (e.g., digging through concrete or landscaping), and your local labor and material costs. Larger jobs like replacing the entire sewer line from the home to the street can be the most expensive.
