Our Trench Sewer Line Repair

Our traditional trenching methods allow us to safely and effectively excavate your sewer line to perform the required repairs or sewer line replacement. We’ll promptly mark, secure any necessary permits, and carefully excavate your line to perform the work. We can repair damage caused by shifting soils, frost, corrosion, construction work, and other issues.

Our technicians will repair the damaged section and then thoroughly test your pipes to confirm the issue is resolved. We adhere to the strictest safety and quality control standards and guarantee code compliance with our services.

Signs You Need Sewer Line Repairs

We strongly recommend all homeowners pay close attention to the operation of their plumbing systems. Often, minor annoyances can indicate significant problems that require repair before they get worse. Fortunately, by monitoring the performance of your plumbing, most issues that are caught early can be easily resolved.

If you notice any of these issues, we recommend scheduling a service right away:

  • Slow drainage: Slow drainage from one drain can indicate a minor clog, whereas slow drainage from multiple drains can indicate a more significant blockage.
  • Leaks: Pooling water or water dripping from ceilings or down walls can indicate broken pipes, failed connections, and other problems.
  • Noxious odors: Noxious odors occur as sewage decomposes in the pipes. It’s a sign that the pipes aren’t draining properly.
  • Lush landscaping: Lush spots in the landscape often indicate excessive water being fed to the lawn via cracks in the sewage line.
  • Frequent backups: Sewage backups into the tub, sinks, or toilets should always be promptly investigated as these can indicate a significant clog or broken pipe.
  • Gurgling sounds: Gurgling sounds occur when air gets trapped within pipes. This happens due to insufficient flow through the pipe, which is often caused by a blockage, deformity, or broken pipe.

Trench Sewer Line Repair FAQs


Sewer line video inspections allow us to insert a specialized camera deep within your sewer line. This way, we can identify corrosion, broken pipes, clogs, tree root infiltration, and other issues.

It depends on the extent and cause of the problem, the weather, and the complexity of the required repairs. Before starting work, our team will thoroughly assess various factors and provide an accurate timeline for your repairs.

We strongly discourage DIY sewer line repairs. Doing so can cause extensive damage to your landscaping and plumbing. The task also requires specialized training and skill to perform safely and in a manner that permanently restores the condition of your sewer line.

Garrett and Stephen came out and quickly and professionally replaced our 70-year-old sewer plumbing after it cracked. They worked super hard and ensured we had working plumbing each night and through the weekend. They finished and cleaned up and I would highly recommend them.

Chris was a very professional, knowledgeable, polite and patient plumber. They said he'd be here within the hour, he was here in 20 minutes. Pieces were missing from our brand new toilet to be installed, he was willing to take his lunch and allow us the time to run to Home Depot to exchange the toilet. Once we had all the parts, he installed it…
