Recurring Drain Blockages

If your drains keep blocking despite being cleared, there's almost certainly an underlying structural problem. Repeated blockages are a symptom — not the disease. A proper investigation will reveal the root cause and allow us to fix it permanently.

What to Look For

  • Blockages that return within weeks or months of clearing
  • Multiple drains blocking at the same time
  • Blockages in the same location every time
  • Foul smells between blockage episodes
  • Increasing frequency of blockages over time

How We Diagnose the Problem

A CCTV drain survey reveals why blockages keep recurring. Common causes include partial pipe collapses creating snag points, displaced joints trapping debris, tree root ingress, incorrect pipe gradients, or bellied (dipped) pipe sections where waste accumulates.

Think you might have recurring drain blockages? A professional inspection will confirm the diagnosis.

How We Fix It

Once we identify the structural cause, we provide a permanent fix — whether that's relining cracked or displaced joints, cutting out roots and sealing the pipe, or replacing a section that has collapsed or lost its gradient.
