Recurring Blockage Investigation
If clearing the blockage only buys you a few weeks, the real cause is still down there. We find it — and fix it properly.
A drain that blocks again and again almost always has an underlying cause: root ingress, a partial collapse, displaced joints, heavy scale, or a section of pipe with the wrong fall. Repeatedly clearing it treats the symptom, not the problem.
Our investigation uses a camera survey to identify exactly why the blockage keeps coming back, so you can invest in a fix that actually lasts.

Recurring Blockage Investigation — your questions answered
Why does my drain keep blocking even after it is cleared?
Because clearing removes the blockage but not its cause. Tree roots, a collapse, scale or a poorly laid section will keep catching debris until repaired.
What is the permanent fix?
It depends on the cause — options include root cutting, drain relining, a localised patch repair, or excavation for a collapse.
