THE SMARTER WAY TO FIX PIPES
Horizontal Boring for Less Digging
Trenchless repair, also called horizontal boring or horizontal directional drilling, lets us replace or rehabilitate underground pipes from just two small access points. No trench. No demolished driveway. No weeks-long excavation project. For most Issaquah homeowners, the job is complete in a couple of days.
Homes built near Issaquah's original townsite in the 1950s through 1970s commonly have clay or Orangeburg sewer pipes. Both materials are notorious for root intrusion and cracking. The Douglas firs and big-leaf maples that define Issaquah's character send roots straight into old sewer lines, and once they find their way in, backups follow.
On the water main side, galvanized steel service lines in older Issaquah homes have spent decades exposed to the naturally soft water of the Issaquah Creek watershed. Soft water is more corrosive to metal than hard water. It pulls minerals from the pipe walls rather than depositing them. The result is rust discoloration, reduced pressure, and eventually a leak.
How Trenchless Pipe Repair Works
THE PROCESS
Camera Inspection
We send a high-definition camera down your line to locate cracks, root intrusion, collapses, or offset joints. You see exactly what we see — no guessing.
Diagnosis & Quote
We explain what we found, walk you through your repair options, and give you a honest assessment.
Trenchless Repair
Working from small access points, we utilize horizontal boring and then pull the new pipe through. No trench is needed across your lot.
Final Checks
We run the camera again to confirm a clean, sealed line. You get a post-job inspection video, a written warranty, and a yard that is still intact.
