Trenchless Sewer Repair Pros and Cons

Trenchless Sewer Repair Pros and Cons

Trenchless sewer repair pros and cons. It used to be a plumber had to spend several days tearing up your yard from your house all the way to the curb if they needed to replace a sewer line.

No more, modern video camera technology allows plumbers to be able to easily locate and fix or replace your plumbing pipes. The best part about this is that it all can be done a single day with minimal holes being dug. This means that your yard or landscaping won’t be destroyed while replacing your underground water and sewer lines.

Trenchless sewer repair is used to help remove roots that cause sewer backups as well as repair cracks in cast iron pipes that are causing leaks. Many plumbing companies will recommend you demolish your walls and floors but this is not always necessary.

Inner pipe lining lasts up to 100 years and only reduces diameter in pipes about 4%. Any kind of diameter storm, sewer or rain drain can be relined.

What is trenchless sewer repair and how does it work?

If you’re constantly dealing with leaking, damaged or old problemed pipes then trenchless sewer repair may be an option. It’s an innovative and cost effective way for you to repair underground pipelines without extensive excavation, disruption and property damage.

With trenchless sewer line repair, only two access holes need to be dug. One pit is dug at the curb and a small pit is dug near the house. The job can usually be completed in 8 hours or less and all your trees, plants, driveways, sidewalks, fence, etc. remain untouched.

After the two holes are dug a bursting head is hydraulically pulled through the existing sewer line by breaking it up the old pipe so that it crumbles in the ground. Behind the bursting head connection is a standard 4-inch polyethylene pipe that’s fused together. It’s melted together so as the bursting head travels through the existing pipe one continuous line is pulled through.

Once the bursting head has been connected to the new pipe and the old pipe is broken apart the new pipe is left in its place.

Trenchless Sewer Repair Pros and Cons


  • Because there is less digging needed to be done by the technicians the cost of the plumbing job is often much cheaper. Homeowners can save up to much as 40% on repair costs.
  • Because only two access holes need to be dug it’s a rather unobtrusive process because your landscaping, garage, and driveways remain untouched.
  • The process can be completed faster, normally within one day compared to traditional methods that take two days or longer.
  • Sewer cameras are used to diagnose and pinpoint the exact location that is in need of repair.
  • Convenience. You don’t have to move out of your home and go live in a hotel. All of the plumbing work is done outside the home and installation can take place early morning or late at night.
  • No strangers doing messy work inside your home for weeks.
  • Old worn out pipes are replaced with very high-quality pipes so you probably won’t have to deal with sewer line problems for a long time.


  • Sometimes the rehabilitation of pipes is out of the question because the joints of the pipe make trenchless repair impossible. If the sewer line is horribly broken then manual trenching may be the only option.
  • Trenching is illegal in some municipalities.
  • If trenchless repair is not done by a reputable plumbing company and can cause serious problems and end up costing more in the long run.
  • It may be challenging to find a plumbing company who have the specialized training needed to do this type of work.

No homeowner wants their property torn up when they are experiencing a major sewer problem. With “no dig” trenchless sewer repair you get an easier, cleaner and more economical way of having your sewer line replaced.

We recommend using trenchless technology when feasible for pipe lining and pipe bursting but understand that in some cases traditional trenching may be your only option. A qualified and ethical plumbing company can help you choose which option is best for you. Hopefully, it’s the option that preserves your existing fixtures and landscaping.
