Does relining reduce the pipe diameter?

Marginally — the liner adds a small wall thickness, but flow capacity is essentially unaffected for standard domestic drainage.

What's included

What's included.

Drain relining begins with a CCTV survey to confirm the run is a suitable candidate for the process, since not every defect can be relined. A cured-in-place resin liner is then installed through existing access points, forming a new structural pipe within the old one without any excavation. Once the resin has cured, we inspect the result on camera before signing off the work. This makes relining particularly well suited to cracked or root-affected pipework where the underlying structure is still largely intact, and to older clay or cast-iron drainage runs under driveways, patios or established gardens that owners are keen to avoid digging up.

Signs you need this

Signs you need drain relining.

Relining is typically the right option when a CCTV survey shows cracking or root ingress but the pipe structure itself is still largely sound, rather than fully collapsed. It's especially worth considering if you want to avoid excavating under a driveway, patio or mature garden, or if you're dealing with repeated root ingress at the same point despite previous clearing work. Older clay or cast-iron pipework showing general wear, without full structural failure, is also a strong candidate for this approach.

How it works

Everything you need to know about drain relining.

1. Survey and assessment

A CCTV survey confirms the pipe is suitable — severe collapse still needs excavation, so this step avoids relining a run that won't hold.

2. Liner installation

A resin-saturated liner is inserted through existing access points and cured in place, forming a new pipe within the old one.

3. Final inspection

A final CCTV pass confirms the lining has cured correctly and that flow is fully restored along the whole run.

FAQ

Answers before you call.

Often yes overall, once the cost of reinstating a dug-up driveway or garden is factored in — though the right answer depends on the specific defect, and we'll recommend excavation honestly where that's genuinely the better option.
