Drain Lining in Holborn: Advice & Costs
Drain lining installs a new structural pipe inside the old one — resin-saturated liner, inflated and cured in place. Done properly it is a permanent repair; the craft is in the preparation and the curing.
What the work involves
- CCTV survey and thorough cleaning/descaling of the host pipe
- Liner sized and impregnated for the run or a localised patch
- Inversion or winched insertion, then ambient/hot cure
- Post-lining CCTV proving the finished bore
Cost and lifespan, honestly
Lining prices per metre — typically mid hundreds for short domestic sections, rising with diameter and length — and cured liners carry design lives commonly stated around fifty years. The quote should include pre-jetting, the cure method (ambient, hot-water or UV — the last curing in minutes rather than hours), and post-lining CCTV proof.
Lifetime cost, versus the dig
Compare full lifetime costs: the liner’s price today plus nothing for decades, against excavation plus reinstatement plus the garden’s restoration — and the liner usually wins under any surface that is costly to reinstate. Excavation wins on open ground and single short sections; the comparison cuts both ways.
The pre-lining checklist
Before lining begins: post-jetting footage showing a clean bore, the defect list matching the survey you were quoted from, the cure method and its log, and confirmation your junctions will be robotically reopened. A five-minute checklist protects a repair designed to last fifty years.
Bends, junctions and short sections — the edge cases
The awkward cases have established answers: moderate bends take the elasticised flexi-liners built for them; junctions are lined past and then robotically reopened — or dressed with a purpose-made junction (‘top-hat’) liner that seals the connection itself, the classic fix where a branch joint leaks; and single short defects get patches rather than paying full-lining mobilisation for one metre of problem. Where quotes diverge on an awkward run, it is usually because each firm favours the equipment it owns — ask which of these three answers your survey’s geometry actually calls for.

Common questions
Does lining reduce the pipe size?
By a few millimetres of liner wall — and because the new bore is smooth, flow usually improves rather than suffers.
Can a lined drain be lined again?
Generally you patch a liner rather than re-line — one reason to insist the first installation is evidenced with CCTV.
Why do lining quotes vary?
Preparation is the hidden variable: descaling, root cutting and reinstating connections. The cheap quote often simply excludes them.
The liner failed early — what recourse?
The written guarantee first, the installer second — and if the guarantee was insurance-backed, the insurer stands behind it even if the installer is long gone. This is why that question gets asked before, not after.
Lining a shared drain — do neighbours pay?
Where the run serves several homes it may be the company’s to fix free — check first. Genuinely private shared runs: split by benefit, agree in writing, and copy everyone the footage.
