There are many factors to consider when calculating the cost of sewer line replacement and repair. Even simple maintenance can be expensive but can provide home owners with warning signs of a clogged sewer line. The cost of sanitary sewer line replacement is significantly higher than a simple fix and the cost can be significant if sewer lines are not consistently maintained. Routine sewer main inspection can minimize repair costs for a bigger problem like a sewer backup. Here are some of the biggest factors to consider when determining the cost of main sewer line replacement and repair.


PVC and ABS pipes are popular materials used for main line replacement. These materials are lightweight and easy to install, and plumbers prefer them because they don’t require excavation and are usually compatible with non-invasive methods. HDPE (high-density polyethylene) pipes are durable and flexible, but they also have a higher cost. Homeowners insurance doesn’t cover broken sewer pipes due to natural causes like tree roots.

Complete line replacement

This is the most expensive option, because it requires excavation and trenching the yard to reach the city tap. It’s the last option for bad lines, and the average cost is anywhere from $5,000 to $15,000 depending on the size of the pipe. However, if you have a cracked sewer line, this may be the most economical solution as well as the only solution. The cost of complete line replacement is around $20,000 which is far more expensive than the sewer line repair cost. There are several types of sewer line repair, so it’s worth getting an estimate to see which one is the best for your particular situation.

The cost of sewer line repair is highly dependent on the severity of the clog and the accessibility of the line. Older homes have old pipes, it may not have a cleanout, which means there are several turns and connection points throughout the house. If the clog is larger, underground utility experts need to spend more time and labor cleaning it, which increases the price. In addition, larger clogs require more effort to remove, so it’s important to call a company with underground utility services. When you contact a service company for your sewer line problem they will use video inspection to look at the sewer system and entire line. This method allows the expert to look at the plumbing system, PVC pipes, and sewer trap to find the clogged drain. Once the drain problem is found, the utility service will work with the property owners to find the best way to fix the sewer line damage.

The length and depth of the sewer line can also increase the overall cost. If you’re replacing a sewer line in your home, the work will likely be easier if you dig a trench. Fortunately, you’ll pay much less for a repair than a full replacement. Some utility services offer directional drilling that does not require trenching and solves installation problems with minimal environmental impact. Trenchless sewer line repair minimizes the damage to your yard. For a long run of existing pipe, directional drilling might be a good option for trenchless sewer repair. Nevertheless, if it’s already too deep or damaged, a professional will use heavy equipment to ensure that the job is done properly.

If you’ve been experiencing any of these problems, you probably need to have your sewer line replaced. There are many symptoms that indicate that you need to have your sewer line repaired, and a trained specialist can determine which one will be the best option for you. Having the sewer line repaired is an expensive project, so it’s best to choose a professional to do the job. A good utility service company will help you determine what type of sewer line replacement is right for you and your home.
