Sewer Line Repair Cost

Sewer line repair costs depend on the method used. Various techniques have different price ranges and levels of effectiveness.

Sewer Line Repair Cost By Method

CIPP$90 – $250 per linear foot
Spin-casting$80 – $250 per linear foot

Pipe Bursting

Pipe bursting is a trenchless method that involves breaking and expanding the existing pipeline while simultaneously laying new pipe in its place. This can cost between $60 to $200 per linear foot.

CIPP

Cured-In-Place Pipe (CIPP) is another trenchless technique where a resin-saturated felt tube is inverted or pulled into a damaged pipe. It can cost $90 to $250 per linear foot.

Spin-Casting

Spin-casting involves applying a new epoxy or cement lining to the interior of the existing pipe. This repair method ranges from $80 to $250 per linear foot.

Snaking & Hydro Jetting

Snaking, also known as rooting, involves using a cable machine to clear out blockages. Hydro jetting uses high-pressure water to clean the pipe. Snaking costs between $150 and $500, while hydro jetting ranges from $250 to $800.

Sewer Line Replacement Cost Factors

Several factors can influence the overall cost of replacing a sewer line:

Labor

Labor costs can vary significantly depending on the region and the complexity of the job. Skilled labor is required for the replacement process, impacting the total cost.

Sewer Line Materials

The type of material used for the sewer pipe also affects the cost. Below is a table indicating the cost by material:

Pipe MaterialAverage Cost per Linear Foot
Cast-iron$20 – $75
Copper$30 – $80
PEX$2 – $10
PVC$3 – $8
ABS$3 – $11

Traditional vs. Trenchless Digging

Traditional digging methods require extensive excavation, which can be costly and time-consuming. Trenchless methods, such as pipe bursting and CIPP, typically have higher per-foot costs but involve less disruption and faster completion times.

Other Costs

Additional costs may include permits, inspections, landscaping repairs, and any unforeseen issues that may arise during the process.

Sewer Line Repair & Replacement FAQs

How Long Does It Take To Replace Or Repair A Sewer Line?

How Do I Know If I Need To Replace Or Repair My Sewer Pipes?

Signs that you may need a sewer line repair or replacement include frequent backups, foul odors, unusually lush patches in your yard, increased pest activity, or visible damage to the sewer pipe.

Does Homeowners’ Insurance Cover Sewer Line Repair Or Replacement?
