Drain Line Repair in Langley, BC


Why Pipes Break


Underground pipes face constant stress. The most common causes include:

  • Tree and shrub roots growing into joints and cracks
  • Shifting or settling soil that bends or crushes the pipe
  • Age and corrosion, especially in older clay or metal pipes
  • Older clay or concrete pipes often require upgrading after their lifespan
  • Heavy loads from vehicles or construction above the line
  • Freeze and thaw cycles that crack weakened sections
  • Blockages that build pressure until the pipe fails

How We Repair Pipes

We locate the fault, expose the damaged section, and replace or reline it so water flows away from your property again.


Every repair is tested before we backfill, so you can rely on the result.



We guarantee our repairs so you can rest assured it will continue to hold.

Upgrading Clay and Concrete Pipe to PVC

Older clay and concrete pipes crack, shift at the joints and let roots in. We replace them with durable PVC that stays smooth, sealed and watertight for decades.

  • Sealed joints that keep roots out
  • Smooth walls for better flow and fewer blockages
  • Lightweight, long-lasting and code-compliant
