When a drain begins to crack, leak, or show signs of wear, many homeowners worry they’ll need excavation. Thankfully, drain relining offers a cleaner, faster, and far less disruptive way to repair damaged pipes in Plymouth.

Our local engineers carry out professional drain relining across Plymouth, Plympton, Plymstock, Saltash, Tavistock, Ivybridge, Torpoint, and surrounding areas. This no-dig method restores your drains from the inside out, strengthening them for decades.

What Is Drain Relining?

Drain relining repairs damaged drains by installing a new internal lining inside the existing pipe. A flexible liner is saturated with resin, positioned inside the drain, inflated, and left to cure. Once hardened, it forms a smooth, watertight pipe within the original pipe.

This process eliminates the need to dig up gardens, driveways, or paths. It’s ideal for pipes that still hold their shape but have cracks, leaks, or early signs of structural fatigue.

Why Plymouth Homeowners Choose Drain Relining

 

Relining costs significantly less than traditional excavation and reinstatement. Without digging, you avoid restoring paving, soil, concrete, or landscaping.

Most relining jobs are completed the same day, with very little disruption to your home or routine.

There’s no digging or trenching. Repairs are carried out through existing access points.

A relined pipe is resistant to corrosion, root intrusion, chemical wear, pressure, and cracking. The new lining often lasts for several decades.

Less heavy machinery, less waste, and less disturbance to soils and ground conditions.

 

When Drain Relining Is the Best Option

 

Drain relining is suitable when:

  • The pipe has cracks, minor fractures, or leaking joints

  • You have ongoing root intrusion but the pipe still holds its shape

  • Excavation is impractical due to buildings, concrete, or landscaping

  • You need a quick, long-lasting solution with minimal downtime

  • The drain has repeated problems but is not collapsed

A CCTV drain survey is always carried out first to confirm the pipe is suitable for relining.

Relining isn’t recommended when:

  • The pipe has fully collapsed

  • The pipe is severely deformed or misaligned

  • There is no suitable access point

  • The cost becomes high over very long distances

In these situations, a traditional repair or pipe section replacement may be required.

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.

Karen Burroughs

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!

Drain relining repairs damaged pipes by installing a new lining inside the old one. A resin-soaked liner is inserted, inflated, and cured to form a watertight inner pipe.

In most cases, yes. It’s quicker, cleaner, and avoids the heavy disruption that comes with digging up gardens, driveways, or flooring.

A quick, targeted repair using a resin-coated fibreglass patch to fix a small, localised defect without relining the entire pipe.

Yes. Once installed, the new lining shuts out roots and prevents them from re-entering.

As long as the pipe hasn’t fully collapsed or become severely misshapen, relining is usually an option.

The liner slightly reduces the pipe’s internal diameter, but the smoother interior improves flow in nearly all cases.
