Trenchless vs. Standard Sewer Line Repair: Pros & Cons

A clogged sewer line is not a problem that will solve itself or go away if you ignore it. Instead, the problem will continue to worsen until you finally discover that raw sewage and dirty water are backing up into your home. And at that point, you will be forced to deal with this annoying and sometimes expensive repair.

The most common cause of a sewer line clog is damage to the pipe itself. It might be a crack from an aggressive tree root or a broken joint, but the result is always the same. Once there is any damage to a sewer line, water, and waste leak out while dirt and tree roots begin to invade the pipe. Soon, the blockage stops water and waste from draining into the city sewer system, and you are facing a nasty mess of contamination in your home.

Fortunately, you have many options when it comes to repairing your sewer line. There is the traditional method of digging up the damaged section and replacing it. And there is also a more modern process called trenchless sewer line repair. This method uses a liner and epoxy compound to make the repair without needing to dig up the pipe. To help you decide which method will work best for you, we have compiled a list of Pros and Cons for you to review.


  • Saves Time And Money- The trenchless method eliminates the time needed to excavate the pipe. And that means that you are paying less for the total amount of labor necessary to complete the project.
  • Less Inconvenience- The trenchless process is often faster than the traditional method by several days. So you will not be without functional toilets and drains in your home for many days. That can be a stressful event in an already busy household.
  • Less Destruction- Many homeowners choose to put off a sewer line repair because they don’t want to look at the massive scar that it will leave in their yard and landscape. Trenching is very destructive. Depending on the location of your sewer line, the trench could destroy your lawn, driveway, sidewalk, and some plant material.
  • A High-Quality Solution- Trenchless sewer line repairs use a cure-in-place liner that carries a warranty that is as long as 50 years. And because the new liner is not made of metal, you will never have any corrosion issues at the repair location.
  • Meets Code- The CIPP trenchless sewer line repair process meets all building codes in the U.S. for sewer line replacement and repairs.


  • Not Covered By Homeowners’ Insurance- You will need to check your homeowner’s insurance policy to determine if repairs or tree root invasion of your sewer line are covered.
  • Trenchless Could Be More Expensive- If your sewer line does not run under your driveway or near expensive landscape material, a traditional repair could be more affordable. The only way to be sure which option is the best for your home is to get price quotes from a licensed plumber for traditional and trenchless repairs.
  • This Process Requires Significant Expertise- The process of trenchless sewer line repair is far more intricate than merely digging a trench and repairing a damaged pipe. The process requires a great deal of training and experience to be completed in a professional, high-quality manner. Remember, your sewer line replacement will only be as reliable as the company that you hired to complete the work for you.
