Luke U.
Jacob was fantastic to work with, as he was not pushy like the Anderson guy who used scare tactics, tried to upsell unnecessary add-ons, and even asked what our budget was. Jacob was very responsive and worked incredibly hard to accommodate our requests.
Michael K.
The installation was fast, just a day or two after the agreement was signed. The installation team was friendly, informative and skilled. They also discovered a leak in the vent seal and scheduled a roofer to take care of that. All in all this was a positive experience.
Judy T.
Ramon arrived right on time and was very professional. He knew exactly what needed to be done and explained it so I would understand why the old plumbing pipes were near the end of their life. He did a great job and was cheerful and very pleasant. I would highly recommend Thompson Plumbing and would definitely ask for Ramon again.

Called Thompson plumbing for an issue I had while changing out my shower valve. Thomas plumbing sent technician Jose Reyes within one hour. Jose promptly diagnosed the issue and gave me a reasonable quote. Once I accepted the quote he went to work and completed the job in a timely manner, Jose did a great job. Very satisfied
Travis M.
We had a great experience with Thompson Plumbing. Jose and Ignacio installed a tankless water heater, a whole house filter and replaced a whole bunch of old copper pipe. All around professionalism from booking the appointment to paying for the work. We now have a go to plumber here in Oceanside!

What Happens If You Wait Too Long

Putting off sewer line replacement rarely makes the problem go away. In most cases, a small crack or clog gets worse over time, especially with Oceanside’s mix of older clay piping and mature tree root systems that are drawn to moisture. What starts as a slow drain can turn into a full backup that damages your flooring, walls, and personal belongings.

Delaying repairs can also mean higher costs down the road. A minor repair job can turn into a full excavation project if the pipe collapses or a break spreads contamination into the surrounding soil. Beyond the property damage, a failing sewer line poses a real health risk to your household, since raw sewage exposure can lead to serious bacterial and mold issues. Acting early almost always saves you time, money, and stress.

How We Handle Your Sewer Line Replacement

Our process starts with a thorough inspection using video camera technology so we can see exactly what is happening inside your pipes. This lets us pinpoint the location and cause of the damage instead of guessing, which saves you time and unnecessary digging. From there, we walk you through what we found and explain your options in plain language, so you understand exactly what is being recommended and why.

Once we agree on the right approach, our technicians get to work using methods suited to your property and the extent of the damage. We take care to protect your landscaping and minimize the footprint of the job wherever possible. After the new line is in place, we test the system thoroughly to confirm everything is flowing properly before we consider the job complete.

Trenchless Sewer Line Repair Options

Traditional sewer line replacement often means digging up your entire yard, but trenchless technology has changed that. With trenchless methods, we can replace or reline your sewer pipe through small access points instead of a long open trench. This means less mess, less time, and less damage to your landscaping, driveway, or hardscaping.

Trenchless repair works especially well for older Oceanside homes where mature trees and established yards make traditional digging more disruptive. It is also a great option for homes with root intrusion issues, since the new pipe material resists roots far better than aging clay or cast iron lines. We will assess your property and let you know if trenchless repair is the right fit for your situation.
