Sewer Repair & Replacement

A Broken Sewer Line Doesn't Have to Mean a Torn-Up Property

A failing sewer line is one of the more disruptive problems a property can face. Backups, foul odors, standing water, and in serious cases, damage that spreads into a building itself. For a long time, fixing it meant digging up the line, which usually meant tearing up parking lots, landscaping, or even building foundations to get to the pipe.


That's not always necessary anymore. West Coast Hydro-Jet repairs and replaces sewer lines using both traditional and trenchless sewer repair methods, including pipe bursting and pipe lining, chosen based on what actually fits your property and the specific damage involved. Commercial properties avoid the cost and disruption of a torn-up parking lot. Multi-family communities avoid displacing residents during construction. Hospitals and schools avoid the kind of extended disruption that a full excavation can cause. And homeowners avoid losing a section of yard or landscaping they'd rather keep intact.


We've repaired sewer lines throughout Los Angeles, Orange County, the Inland Empire and San Diego for more than 34 years, with our own certified technicians handling every job from diagnosis through final repair.

Signs of a Failing Sewer Line

Sewer line problems tend to show up gradually before they become an emergency. Watch for:

  • Recurring backups, especially in the lowest drains or fixtures in a building
  • Slow drainage across multiple fixtures, which points to a main line issue rather than one clogged drain
  • Sewage odors around the property, particularly near cleanouts or low-lying drains
  • Wet or unusually green patches in the yard, which can indicate a leaking line below
  • Cracks in flooring or foundation settling, in more advanced cases where a line has been leaking for some time
  • Multiple units or tenants affected at once in a multi-family or commercial property, pointing to a shared line


Catching these early usually means a smaller, less invasive repair. Waiting tends to mean a bigger one.

Two Ways to Fix a Sewer Line & When Each Makes Sense

Traditional sewer repair means digging a trench along the length of the damaged pipe to access and replace it. It's a proven method, and for certain types of damage, especially severe structural collapse, it's still the right call.


Trenchless sewer repair takes a different approach. Using methods like pipe bursting or pipe lining, we can often repair or replace a damaged sewer line by accessing it from just one or two points, without digging up the entire length of the pipe. That means no torn-up parking lot, no destroyed landscaping, and significantly less disruption to a property's daily operations.


Not every situation is a fit for trenchless sewer repair. The right method depends on the pipe's condition, material, and the type of damage involved, which is why we start most sewer repairs with a video inspection to see exactly what we're dealing with before recommending an approach.

From Diagnosis to Repair

Most sewer repairs start with a camera inspection, so we can see the exact location, cause, and severity of the damage before recommending a fix. From there, we walk you through the repair options that fit your situation, including trenchless methods where they apply, along with a clear, upfront price before any work begins.


Once a repair method is chosen, our own technicians complete the work, whether that's a trenchless repair completed with minimal disruption or a traditional excavation where that's genuinely the better option. Either way, we test the repaired line afterward to confirm it's flowing correctly before we consider the job finished.

The Plumbers Your Plumber Calls

  • Trenchless Options - Repair sewer lines with minimal digging, where the damage allows for it
  • Video-Verified Diagnosis - We see the problem before we recommend a repair
  • Self-Performing Technicians - Our crews, our equipment, no subcontractors on your property


Sewer repair is exactly the kind of job where cutting corners costs more later. Our technicians are trained on both trenchless and traditional repair methods, so the recommendation you get is based on what your property actually needs, not on what a crew happens to be equipped to do that day.

Frequently Asked Questions About Sewer Repairs

  • What is trenchless sewer repair?

    Trenchless sewer repair fixes a damaged sewer line without digging up its entire length, using methods like pipe bursting or pipe lining accessed from one or two points instead of a full trench.

  • Is trenchless repair always possible?

    No. The right method depends on the pipe's material, condition, and the type of damage. Severe structural collapse, for example, may still require traditional excavation. We determine the best approach after a video inspection.

  • How do I know if I need sewer repair or just a cleaning?

    Recurring backups, slow drainage across multiple fixtures, and sewage odors can indicate either a clog or a structural problem with the line itself. A camera inspection is the most reliable way to tell the difference.

  • What's the difference between pipe bursting and pipe lining?

    Pipe bursting breaks apart the old pipe while simultaneously pulling a new one into place. Pipe lining inserts a new liner inside the existing pipe, creating a pipe within a pipe. Both are trenchless methods; which one fits depends on the pipe's condition and the type of damage.

  • Does West Coast Hydro-Jet repair sewer lines for both commercial and residential properties?

    Yes. We repair sewer lines for commercial and industrial properties, multi-family communities, hospitals and schools, and residential homes throughout Los Angeles, Orange County, the Inland Empire and San Diego.
