Trenchless Drain Repairs for Homes and Businesses Across Cornwall
When drains begin to leak, crack, or block repeatedly, excavation used to be the only option. Today, homeowners across Cornwall can benefit from drain relining — a clean, efficient, and durable method of repairing damaged pipes without digging.
Our local engineers provide expert drain relining throughout Truro, Falmouth, St Austell, Penzance, Bodmin, Redruth, Camborne, Helston, Newquay, and beyond. If your drains are showing early signs of deterioration, relining can restore them quickly and with minimal disturbance.
What Is Drain Relining?
Drain relining reinforces damaged drains by installing a new lining inside the existing pipe. The liner is soaked in resin, fed into the drain, inflated, and left to cure. Once set, it forms a smooth and watertight inner pipe.
The process avoids excavation, making it ideal for Cornwall homes where drains often run beneath driveways, gardens, or old stone pathways.
Why Cornwall Properties Benefit from Drain Relining
Cost-effective
Relining avoids excavation, ground reinstatement, and the cost of heavy machinery or landscaping repairs.
Fast and convenient
Most relining work across Cornwall is completed within a single day.
Low disruption
No digging, no broken surfaces, and no mess — repairs are done through existing access points.
Highly durable
The cured liner resists cracks, roots, corrosion, and wear. Many systems last 50 years or more.
Eco-friendly
Less machinery, less energy, and far less waste than a traditional excavation repair.
When to Choose Drain Relining
Relining is a strong choice when:
-
Pipes have cracks, small fractures, or leaks
-
Root intrusion is present but the pipe is still structurally sound
-
The drain runs under buildings, patios, or landscaped areas
-
You want a long-lasting repair without disruption
-
The pipe shows wear but hasn’t collapsed
Cornwall’s older properties, especially in areas like Penzance, Bodmin, and St Ives, benefit greatly from trenchless methods due to tight access and historic ground structures.

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!

Contact us
What is drain relining?
It’s a trenchless repair process where a new lining is formed inside the old pipe using a resin-saturated liner, sealing cracks and leaks permanently.
When should I choose drain relining?
When large sections of your drain have cracks, corrosion, or root ingress, or if excavation isn’t practical.
What is a pipe patch repair?
A quick, targeted repair using a resin-coated fibreglass patch to fix a small, localised defect without relining the entire pipe.
Will the process damage my property?
No. Both methods are trenchless, so there’s no need for heavy digging, just efficient repairs through existing access points.
How long will the repair last?
Both relined drains and patches can last up to 50 years, depending on usage and pipe condition.
Can you fix any kind of pipe?
Yes. We can repair clay, plastic, concrete, and metal pipes, provided the structure hasn’t completely collapsed.
