Drain Relining
Repair damaged pipes from the inside with a cured-in-place liner: a strong new pipe within the old one, with no digging.
What is drain relining?
Drain relining (cured-in-place pipe, or CIPP) repairs a pipe from the inside. The installer puts a liner soaked in resin into the pipe, inflates it against the old pipe wall and lets it harden. It forms a strong new pipe with no joints, which seals cracks and keeps roots out, with no digging.
Drain relining (cured-in-place pipe, or CIPP) repairs a damaged pipe from the inside. The installer puts a liner soaked in resin into the pipe and inflates it against the old pipe wall. As the resin sets, it forms a strong new pipe with no joints.
Relining seals cracks, stops leaks and keeps roots out, all without digging. That makes it a good fit where the pipe runs under a drive, garden, floor or building.

When you need drain relining
- A survey has found cracks, fractures or open joints
- Root ingress is getting into the pipe
- A damaged section keeps causing blockages
- The pipe runs under a drive, patio, garden or floor you want to protect
Why it matters
No excavation
Since the repair happens inside the pipe, nobody digs up gardens, drives or floors. You avoid the mess, and the cost of putting things back.
Seamless & strong
Because the new liner has no joints, it resists roots and leaks. Roots usually get in at joints, so with none to exploit, the repair has a better chance of lasting.
Long lifespan
A well-fitted liner can add many years to a drain's life. Ask the installer what working life they expect for your pipe.
What it usually includes
Ask the engineer to confirm what their quote covers, since this varies.
- A survey and high-pressure jet-clean to prepare the pipe
- Installation of the resin liner, cured in place
- A final camera survey to confirm a smooth, sealed pipe (ask for it)
- A written quote to ask for before work begins
How it works
- 01
Survey & clean
First, the engineer surveys the pipe and jets it clean, ready for lining. A clean surface helps the liner bond, so this step matters.
- 02
Install liner
Next, the installer puts the liner in, inflates it and lets the resin set. They keep a check on it while it sets, so the new pipe forms as it should.
- 03
Final survey
Finally, ask for a camera survey to confirm the new pipe is smooth, sound and sealed. You then have footage that shows the repair is complete.
How much does drain relining cost?
The cost of drain relining depends on the length and width of the pipe and how many bends it has. Access to the run matters too. It usually costs less than digging out and replacing the same pipe. Send us the details, and ask for a written quote before any work starts.
What affects the price
- The length of pipe that needs lining
- Pipe diameter and how many bends are involved
- Access to the run and the condition of the host pipe
- Whether a patch liner or a full liner is required

Is relining as good as a new pipe?
For many defects, it can be. The liner forms a strong pipe with no joints. It can seal cracks, leaks and root entry points much like a new pipe.
How long does a relined drain last?
Liners can last a long time, but it depends on the product and how well someone fits it. Ask the installer what life they expect, and what cover comes with the work.
Can every drain be relined?
Most can. Still, a pipe that has fully collapsed or lost its shape may need digging out, so a survey should check first.
