Drain Patch Repair – Fixing One Short Section, Not the Whole Drain
Not every damaged drain needs a full-length liner. Where CCTV shows a single defect in otherwise sound pipework, a patch liner can be installed over that short section only — typically a resin-impregnated sleeve positioned on a packer, inflated across the defect and cured in place.
When a patch may be suitable
Patch lining is aimed at defects that are contained rather than spread along the run. A specialist may consider it where CCTV shows:
- An isolated crack in an otherwise sound length of pipe
- A damaged or slightly open joint
- A small root intrusion point, once the roots have been cut back
- A short damaged section, often under a metre
- A defect at a known distance that equipment can reach cleanly
Suitability always depends on the CCTV findings and the condition of the surrounding pipe. If the survey shows several defects along the run, widespread cracking, or a pipe that has lost shape, a full drain relining repair or excavation of the section is more likely to be recommended.
How the work is normally carried out
- Survey. The defect is located and measured from the chamber during a CCTV drain survey.
- Clean. The area is jetted, and roots or protrusions are cut out so the patch can bond.
- Install. The resin-loaded patch is carried to position on a packer and inflated against the pipe wall.
- Cure. The resin sets, the packer is deflated and withdrawn.
- Check. A short follow-up survey confirms the patch is seated and the bore is clear.
Patch repair pricing
As a general orientation, patch repairs at UK residential properties often fall somewhere around £350–£1,200, depending on location, access, pipe condition and the complexity of the repair. Deep chambers, long distances from the access point, awkward junctions and additional cleaning all push the figure upwards. These are market guides only — not a quotation, and not a promise of price.
| Work | Typical UK price guidance |
|---|---|
| Patch repair, single localised defect | £350–£1,200 |
| CCTV survey to locate the defect | £150–£300 |
| Full relining instead of a patch | £70–£170 per metre |
Patch or full liner?
A patch is cheaper and quicker where the problem is genuinely one spot. It does not, however, improve the rest of the pipe. If a survey shows a pipe that is generally deteriorating, repeated patching can end up costing more than lining the run once. That judgement should be made from the footage, and explained to you in the quotation.
What to ask before accepting a patch quotation
- Where exactly is the defect, in metres from which chamber?
- How long is the damaged section, and how long is the proposed patch?
- Are there other defects visible on the same run?
- Will post-repair footage be provided?
- What do the written warranty terms cover?
