Trenchless Sewer Repair

Can this be repaired without tearing up the entire yard?

Trenchless repair addresses a damaged sewer line through limited access points instead of a continuous trench along its whole length. For the right property and the right damage, it means a repaired line and a yard that's mostly left alone. But it isn't a guarantee; eligibility depends on what inspection finds.

Trenchless sewer repair through limited access points in a yard

What it generally means

Repair through two access points, not a trench

Instead of digging up the full length of the line, trenchless methods work through one or two access pits. A new liner or replacement pipe is fed through the existing path, creating a repaired line without excavating everything above it.

The result is far less disruption to lawns, driveways, and landscaping, but the line still has to be reachable and in a condition the method can handle.

Eligibility

What determines whether it's an option

Property where trenchless repair qualifies, yard intact

When it tends to qualify

  • The line is damaged but still continuous enough to accept a liner or bursting head.
  • Access points can reach both ends without major obstruction.
  • The damage type suits the method, such as cracks, minor offset, or root damage, not a full collapse.
Excavation required where trenchless does not qualify

When it may not qualify

  • A collapsed or severely misaligned section can't guide a liner through.
  • Access is blocked by structures, utilities, or property layout.
  • The line has already been patched in ways that interfere with the method.

Side by side

Trenchless vs. conventional excavation

Neither is "always better." The decision starts with what the camera shows, and which approach actually solves the condition it finds.

Trenchless repair with yard mostly intact

Trenchless

  • Two access pits, not a full trench
  • Yard, driveway, and landscaping largely preserved
  • Works through the existing path
Conventional excavation along the line

Conventional

  • Open trench along the damaged length
  • Works on any line, regardless of access
  • Cut and replace the section directly

Find out if your line qualifies

Trenchless can save the yard, but only when the line and access allow it. An inspection tells you whether it's an option for your property, or whether conventional repair is the right call.
