Tree roots enter drains through small defects — usually a weeping joint — and grow toward the moisture. Within a few seasons a fibrous mass can fill the pipe, catching everything that flows past until nothing does. Root blockages do not respond to plungers or drain rods for long: they need mechanical cutting, and an inspection of the defect the roots came in through.
WaterTrust Approved — every contractor is identity-checked with accreditation and insurance verified before they can quote.
What the work involves
- CCTV confirmation that roots are the culprit
- Mechanical root cutting (flail or chain cutters) through the mass
- High-pressure jetting to flush the cuttings
- A repair recommendation for the ingress point — or roots return
When you need it
- Blockages that keep returning every few months
- Slow drains near mature trees or hedges
- Roots visible in a chamber or on a survey
- Gurgling and partial flow that rodding only briefly fixes
What heavy clearance costs in Exeter
Root cutting and descaling jobs typically run £150–£450 — above standard unblocking because they need cutting heads, higher-pressure jetting and more time on site.
What counts as a stubborn blockage
- Dense root masses grown through joints over years
- Hard scale built up until the bore is a fraction of its size
- Cement, plaster or grout washed down during building work and set in the pipe
- Compacted fat that has hardened into a soap-like solid (saponified)
Why standard clearing failed
Rods punch a hole through soft blockages; dense root masses and hard scale close straight back around them. Restoring the full bore of the pipe takes specialist root-cutting heads and, for hard scale, electro-mechanical coring — followed by jetting to flush the lot. If this is the second visit to the same run, put the money toward a survey and a permanent seal instead of a third clearance.
The escalation ladder
Stubborn clearances run in rungs: high-pressure jetting first, then mechanical cutting heads or electro-mechanical coring, then milling for set materials — with excavation only when the pipe itself has failed. A good quote says which rungs it includes and what triggers the next one, so any move to the next stage is agreed with you first.

Deep rooted drain unblocking in Exeter — common questions
Will the roots grow back?
Through the same defect, yes — cutting clears the pipe but the entry point needs sealing (usually a patch or liner) to end the cycle.
Does root cutting damage the pipe?
Proper cutters are matched to the bore. A pipe that cutting could threaten is already defective — which the camera confirms before anyone proceeds.
How long before roots return?
Typically one to two growing seasons through the same joint. Lining after cutting is what ends the cycle.
