No-dig repair assessment
Drain relining can repair some cracked or root-damaged pipes from the inside when CCTV shows the existing pipe can support a liner.

- 01ClearThe pipe needs to be accessible and clean enough for inspection.
- 02InspectCCTV checks the diameter, bends, damage and available repair length.
- 03CompareRelining is compared with excavation or replacement where appropriate.
Fast answer
Confirm the pipe suits relining
Relining can suit an existing pipe that still has enough shape and access for a measured liner. CCTV checks the diameter, bends, damage and repair length before the work is quoted.
Relining may suit when
- 01A repeat problem is confined to a repairable section
- 02Excavation access is difficult or disruptive
- 03The existing pipe retains enough shape for a liner
- 04CCTV shows joints or cracks that may suit relining
Checking suitability
Confirm relining suitability
Relining only suits a host pipe with enough shape and access to support a measured liner. CCTV confirms the defect, diameter, bends and repair length.

- Before quoting or specifying the liner.
- 02
- Pipe preparation

Drain Relining questions
Straight answers about when this service helps, what is involved and what happens next.
View all drain questionsIs relining always better than digging?
No. Relining suits many cracked or root-damaged sections, but collapsed lines, poor access, or certain pipe shapes may need a different repair.
Can a blocked drain be relined immediately?
The drain usually needs clearing and CCTV first. That inspection confirms whether relining is suitable and where the repair should start and finish.
How is a pipe checked for relining suitability?
CCTV and access checks review the diameter, bends, damage, host-pipe shape and repair length. A collapsed or badly displaced section may need a different repair.
What happens before a drain liner is installed?
The repair section is cleared and prepared, the liner dimensions and access are confirmed and the agreed boundaries are explained before installation.
Why is drain relining quoted after CCTV?
The blockage symptom cannot show the repair length, diameter, bends, access or preparation needed. CCTV helps measure and check the section before it is quoted.
