Your sewer line has a crack and you don’t know what to do. You’re afraid of the mess, the cost, and the hassle. 

A cracked sewer pipe can cause all sorts of problems. Not only will it leak wastewater into your yard or home, but it can also lead to extensive and expensive damage if you do not resolve it as soon as possible.

But don’t worry, we have a solution for you. In this article, we’ll discuss your options for fixing a cracked sewer pipe so you can get your home back to normal as quickly as possible. To start, we will discuss the common reason sewer lines break in the first place.

5 Common Reasons Why a Sewer Line Breaks or Cracks

Here are some of the most common reasons why sewer lines break and crack:

1. Tree Roots

Tree roots are a common cause of sewer line damage. They can grow into the pipes and cause them to crack or collapse. This is especially common in older homes with trees close to the sewer line.

If you want to get rid of tree roots in your sewer line, you can use a root killer. This chemical will kill the tree roots without harming your pipes. For more information, check out our article about How to Kill Tree Roots in Your Sewer Line.

2. Clogged Pipes

Clogged pipes can also cause sewer lines to break. If the pipes are full of debris, they can become overloaded and crack under pressure. It’s essential to keep your pipes clear of debris to prevent them from breaking.

3. Soil Movement

Another common cause of sewer line damage is soil movement. This can be caused by floods, earthquakes, and even the freezing and thawing of the ground. When the ground moves, it can pressure the sewer pipes and cause them to crack.

4. Poor Installation

If your sewer pipes are poorly installed, they are more likely to break and crack. This is often the case with older homes that have clay sewer pipes. Poor construction can also lead to problems like joint leaks and pipe collapses.

5. Old Pipes

Older pipes are more likely to break and crack. This is because they are more brittle and less flexible. If your home has older sewer pipes, it’s important to be aware of the risk of cracking and take steps to prevent it.

So, now that we know some of the most common reasons sewer lines break let’s look at your options for fixing them.

two sewer line repair and replacement methods

Option 1:  Traditional Sewer Line Repair

The first option is to have your sewer line repaired by digging a trench. This is the traditional way to repair a sewerline break. This requires digging a trench to access the sewer pipe. Once the pipe is accessed, it can be repaired or replaced.

Option 2:  Trenchless Sewer Line Repair

The second option is to repair your sewer line without digging a trench. This is called trenchless sewer line repair. There are a few different methods used for trenchless sewer line repair, and these are:

  • Sewer Pipe Bursting: This procedure is used when the sewage pipe has significant damage and must be replaced. A machine is used to insert a new sewer pipe into the old sewer pipe, and then the old pipe is burst apart. The new pipe then takes its place.
  • Sewer Pipe Relining: This method is used to repair a damaged sewer pipe without replacing the entire pipe. A new liner is inserted into the old sewer pipe and then inflated. This liner will then harden and create a new sewer pipe.
  • Sewer Spot Repair: This technique repairs a small section of a sewer line. Using a camera to find the area with the damage, then applying a patch over the hole.

How Much Is The Repair Cost For a Cracked Sewer Pipe?

The cost of sewer line repair depends on a few factors, such as the type of damage, the severity, and the location of the crack or damage. The average cost to repair a sewer line using trenchless methods is between $100 and $250 per linear foot.

The average cost to repair a sewer line using traditional methods is between $100  and $450 per linear foot, depending on the depth of the trench, the accessibility of the pipe, and the type of pipe.


There are a few different methods you can utilize in repairing a sewer line, and each one has its benefits and drawbacks. If your sewer line has extensive damage and needs a replacement, trenchless sewer line repair is the best option.

If your sewer line has mild damage, trenchless sewer line repair or sewer spot repair may be the best option. It is always best to consult with a professional before deciding on a repair method.
