Drain Repair
When a drain develops a small crack, a leaking joint, or a localised weak spot, you don’t need to dig up the entire pipe. Pipe patch repair is a quick and highly effective trenchless method that targets only the damaged section, restoring the pipe’s strength without disrupting your garden, driveway, or outdoor spaces.
Our local engineers carry out pipe patch repairs across Truro, Falmouth, St Austell, Penzance, Redruth, Bodmin, Camborne, Newquay, Helston, and surrounding areas.
If you have an isolated issue rather than widespread damage, patch repair is often the perfect solution.
What Is Pipe Patch Repair?
Pipe patch repair reinforces a small section inside the drainage pipe by installing a resin-soaked patch liner. Once in place, the patch is inflated and allowed to cure, forming a watertight, durable seal around the damaged area.
It’s designed for isolated defects such as cracked pipe sections, minor holes, displaced joints, or early root ingress, all without excavation.
Quick and Low Disruption
Most patch repairs take only a few hours, and because the process uses existing access points, your property stays untouched.
Cost-Effective
Only the damaged area is repaired, making it more affordable than relining or full pipe replacement.
Versatile Application
Works on clay, cast iron, concrete, and PVC pipe systems — ideal for Cornwall’s mix of older cottages and modern homes.
Long-Lasting Strength
A properly installed patch can last up to 50 years, reinforcing the pipe and preventing leaks for decades.
Environmentally Friendly
No digging, no waste removal, and no heavy machinery — just a clean repair with minimal environmental impact.
When Patch Repair Is the Best Solution
Pipe patch repairs are ideal when:
-
A crack or fracture is limited to one spot
-
A joint has shifted or is leaking
-
There is minor root ingress at one entry point
-
A hole or defect is threatening to spread
-
Excavation is impractical or would cause costly disruption
-
Time or budget is limited and fast repair is needed
A CCTV drain survey always comes first to confirm patching is appropriate.

Step-by-Step Drain Relining Process
1. CCTV Inspection
We inspect the entire drain with a high-resolution camera to identify cracks, root ingress, blockages, or deformation.
2. Preparation and Cleaning
Using high-pressure water jetting or mechanical cutters, we remove debris, roots, scale, and build-up to ensure the lining bonds perfectly.
3. Liner Measurement and Setup
We take accurate measurements and prepare a resin-soaked liner designed for the exact diameter and length needed.
4. Installing the Liner
The liner is inserted through an access point and pushed into position. An inflatable bladder or calibration hose ensures a snug fit.
5. Curing
The liner is hardened using warm water, steam, or UV light (depending on the system).
6. Final CCTV Check
A final camera inspection confirms a smooth, seamless, and watertight finish.
Highly recommend Drain block sevices. Had a blocked drain, contacted a few companies. Roman was the only one to be of help. Explained everything clearly. Was able to help within the hour. Sorted the problem and cleaned up. Would definitely contact if I have problems in the future. Very happy customer.
An absolutely fantastic service. Prompt, knowledgeable, friendly and professional. Issue resolved and everything explained. Cleaned up afterwards. I am glad to have chosen this company and would not hesitate to use them again if necessary. Would highly recommend to family and friends.
We had blocked drains on a weekend morning and after being let down by multiple other companies, Roman came out to us within 20 minutes of phoning and fixed our drains in 30 minutes. He’s an absolute life saver – will be our first call in the future if we were to ever need him again. Thank you!

What is pipe patch repair?
Pipe patch repair targets a small damaged area inside the drain by installing a resin-based liner patch that cures in place, sealing cracks, holes, or joint leaks.
When is patch repair the right choice?
It’s ideal when the defect is localised, such as a single crack, joint issue, or minor hole, and the rest of the pipe is in good condition.
Can patch repairs fix root intrusion?
Yes, as long as the intrusion is limited to one point. The cured patch seals the pipe and blocks further root access.
Will patch repair require any excavation?
No. The process is completely trenchless and uses existing access points, so your garden, paths, or driveways remain untouched.
How durable is a patch repair?
Patch repairs are built to last decades and are often rated for up to 50 years when properly installed.
What types of pipes can be patched?
We can patch clay, concrete, PVC, and cast iron drains, all common across Cornwall’s older and newer properties.

Most patch repairs in Cornwall are completed within a few hours, allowing you to get back to normal quickly.
