Sewer line replacement costs $50 to $250 per linear foot on average, or $2,000 to $10,000 total for 40 linear feet.
Sewer line repairs cost $150 to $3,800, depending on the method used. Small tree roots or clogs may only need a basic repair, while broken lines and large cracks require full or partial replacement.
Replacing or repairing sewer lines takes 1 to 5 days on average, depending on the number of obstacles and length of the replacement. Trenchless sewer line replacements take much less time to complete than manually digging trenches.
Here are some common signs that indicate a sewer line needs work:
Sewer lines last 30 to 100 years, depending on the material. Outdated Orangeburg and clay sewer pipes last 30 to 60 years, while PVC, cast iron, and copper sewer lines last 50 to 100 years.
The life expectancy of your sewer system will ultimately depend on maintenance, the soil condition, and if any nearby tree roots get inside the pipes.
In most cases, the homeowner is responsible for maintaining, replacing, and repairing their pipes that connect to the main line. However, the city or municipality you live in is responsible if the blockages or issues are in the main city line.
Homeowners insurance policies differ in coverage, but most policies cover damage from faulty workmanship, accidents, or vandalism. Most do not cover regular wear and tear due to lack of maintenance. You can also purchase sewer line insurance, which covers more repairs and damage to sewer systems than basic homeowners' insurance.
