What Factors Into Sewer Repair Costs?

Issues with your sewer system are always unpleasant. Repairs are essential to avoid further damage and ensure your system operates properly. The cost of sewer line repairs varies and often depends on the following factors:

Type of Damage

The type and severity of the damage your plumbing system sustains can play a significant role in the cost of services. Minor concerns often cost less than major problems, which usually warrant more invasive repairs.

Location of the Damage

The location of the damaged sewer line impacts how much repairs will cost. Costs can increase if damaged sewer lines are in areas with limited access due to structures or landscaping. This is because these types of jobs require more labor-intensive work, such as excavating, which adds to the overall expenses.


The materials needed to complete a repair job can affect the overall price. In terms of pipe replacement, forgoing clay or cast iron pipes for modern materials like PVC can affect the total cost.

Sewer Line Repair Methods

Perhaps the most significant factor when it comes to determining sewer line repair costs is the method used. The two most common methods are trenchless sewer repair and traditional excavation.

Trenchless Sewer Repair

This repair and pipe replacement method is designed to be an effective solution for property owners, delivering as little disruption as possible. Trenchless sewer repair eliminates the need for invasive digging. Instead, specialists use strategic techniques to yield long-lasting results. Trenchless sewer repair includes the following procedures:

  • Cured-in-place pipe lining: Ideal for sewer line pipes with minimal damage, this method entails technicians pulling resin-saturated tubing into the pipe, preserving the existing line. It creates a restorative seal that lasts up to 50 years.
  • Pipe bursting: Sewer line pipes beyond repair can be replaced using this trenchless sewer repair method. With advanced technology, technicians break apart the existing pipe while simultaneously running a new one in its place.

Conventional Methods

Traditional sewer line repairs involve removing and replacing the damaged pipe. Here, specialists replace damaged pipes with new ones. Specialists complete this by trenching, shoring, and laying the new pipe.

The construction process typically takes multiple stages, prolonging the project timeline. To access the sewer lines, professionals must perform heavy excavation work, which can leave properties disheveled. Conventional sewer line repair methods can be time-consuming, invasive, and expensive.

Trenchless sewer repair can be more affordable and quicker because it involves very minimal excavating compared to traditional tactics.
