Locate the opening after the growth has been cut back and the pipe cleaned enough to view. Root ingress and blockages can return if the cracked joint or other entry point stays outside the follow-up decision.
Remove roots before deciding whether the pipe needs repair
Blockage history and survey findings need to be read together. Root intrusion can be fine and localised or dense enough to hide the pipe surface, so clearance and diagnosis may need separate passes.
Roots on rods or cutting tools confirm growth inside the drain, but they do not show the size or condition of the opening.
Clean footage must expose the root entry
Roots and trapped debris can hide the joint or crack beneath them. The pipe needs enough cleaning for the camera to show where growth begins and whether the surrounding section remains aligned.
That view separates routine cutting from a repair discussion. A proposal is more useful when it points to a visible opening than when it relies only on the fact that roots were recovered.
Roots returning at the same joint
Root fibres found repeatedly at one position suggest an opening in the pipe, but the cleaned wall still needs to show it. A general note that roots were removed is not enough to locate a repair.
CCTV after cutting can distinguish a local joint or crack from deformation or damage extending along the run. Those conditions do not all call for the same response.
Why repeated clearance may fall short
Removing the obstruction deals with the immediate loss of flow. If the access point remains open, new growth can enter and begin catching material again. That is why the finished view of the pipe matters.
- Can the joint, crack or displaced section now be seen?
- Is the surrounding pipe stable enough for a local repair discussion?
- Would the proposed work close the actual entry route?
- What part of the drain should be monitored afterwards?

Can roots enter at a pipe joint? Yes, where a joint has an opening that gives fine roots a route to moisture inside. The cleaned camera view should be used to identify what is happening at that location. Why do roots cause blockages as well as pipe damage? Growth inside the bore forms a snagging point for paper, wipes, fat and other passing material. The combined mass reduces the space available for flow.
Do you need CCTV if roots came back on the rods? Recovered fibres are a useful clue, but footage can locate the intrusion and show what surrounds it. Talk to us about the blockage history so the inspection starts with the right run.
