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.
What is a recurring blockage investigation?
A recurring blockage investigation uses a CCTV survey to find why a drain keeps blocking. Rather than clearing the same blockage again and again, it identifies the underlying cause — roots, a collapse, scale or poor falls. As a result, you can fix the problem for good instead of paying to clear it repeatedly.
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. Because repeatedly clearing it treats the symptom rather than the problem, the blockage simply returns.
Our investigation uses a camera survey to identify exactly why the blockage keeps coming back. As a result, you can invest in a fix that actually lasts, instead of paying for the same call-out again.
When you need a recurring blockage investigation
- The same drain blocks again within weeks of being cleared
- You have paid for repeated call-outs to the same spot
- Drains are slow or gurgle again soon after clearing
- Smells or damp return alongside the blockages
- There are mature trees near the drain run
Why it matters
Stop paying twice
We fix the underlying cause, so the cycle of repeat call-outs finally ends. As a result, you stop paying to clear the same drain over and over.
Root-cause clarity
You see exactly what is causing the repeat blockages on camera. Because the evidence is on screen, there is no guesswork about the fix.
A lasting fix
We then recommend the right repair — relining, a patch, root cutting or excavation. Consequently, the drain is fixed once rather than patched repeatedly.
What's included
- Clearance of enough of the blockage to pass the camera
- A full CCTV survey of the affected run
- Identification of the root cause — roots, collapse, scale or falls
- A clear, costed recommendation for a permanent fix
How it works
- 01
Clear & inspect
First, we clear enough of the blockage to get the camera through, then survey the run. Because we look before we fix, we treat the cause and not just the symptom.
- 02
Identify the cause
Next, we pinpoint and assess roots, a collapse, scale or poor falls. Meanwhile, we note how far along the pipe the problem sits.
- 03
Recommend the fix
Finally, we give you a clear, costed recommendation for a permanent solution. You then know exactly what the lasting fix involves.
How much does a recurring blockage investigation cost?
The cost of a camera investigation into recurring blockages depends on access and whether the run needs clearing first so the camera can pass. It usually pays for itself by ending repeat call-out fees — send us the details and we will give you a clear, fixed-price quote.
What affects the price
- Whether the run needs clearing before the camera can pass
- How accessible the drains are
- The length of pipe that needs investigating
- Whether a full coded report is required

Recurring Blockage Investigation — your questions answered
How much does it cost to find out why my drain keeps blocking?
It depends on access and whether the run needs clearing first so the camera can pass. However, it usually saves money overall, because it ends the cycle of repeat call-outs — send us the details for a fixed-price quote.
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 you repair the pipe itself.
Won't clearing it again just fix it?
Only temporarily. Because an underlying defect stays put, the blockage returns — often within weeks — so a camera investigation finds the cause and fixes it once.
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, and we recommend and quote the right one.
