Trenchless Drain Repairs & Pipe Relining across Coventry

Trenchless drain repair — also known as no-dig repair — fixes damaged drains without excavating your garden, driveway, patio, or interior flooring. Pipe relining is the trenchless method we use most often: a flexible liner saturated with structural resin is inserted into the damaged pipe and inflated against the pipe walls. Once the resin cures — typically within a few hours — it forms a smooth, jointless pipe within the original pipe, sealing cracks, bridging gaps at displaced joints, and blocking root entry points. This is sometimes called CIPP, short for cured-in-place-pipe, the industry term for exactly this process. The result is effectively a new pipe installed inside the old one, with a design life of 50 years or more.

Pipe relining is suitable for repairing cracks, fractures, root damage, joint displacement, and localised corrosion in pipes from 100mm to 300mm in diameter, and it works on all common pipe materials including clay, concrete, cast iron, and plastic. Compared with traditional excavation, trenchless relining avoids the cost of digging up and reinstating hard landscaping — often the largest single cost in an excavation repair — and is typically completed in a single day rather than the one to three days a dig-and-replace repair can take. Our engineers use CCTV inspection before and after relining to confirm the repair is precise and the finished lining is defect-free.

Signs you need trenchless drain repairs & pipe relining help

  • ✓ A CCTV survey has identified cracks, fractures, or displaced joints in your underground drainage
  • ✓ Tree roots are entering your pipes through damaged joints and causing recurring blockages
  • ✓ Damp patches or subsidence near drainage routes suggest leaking pipes underground
  • ✓ Your drains are beneath a patio, driveway, or extension where excavation would be extremely disruptive
  • ✓ You want a long-lasting repair without the cost and disruption of digging up and replacing pipes

Our process

  1. 1.
    CCTV Assessment

    We survey the damaged pipe to map the exact location, length, and nature of the damage. This determines whether relining is suitable and what liner specification is needed.

  2. 2.
    Pipe Preparation

    The pipe is cleaned by high-pressure jetting to remove deposits, root fragments, and debris. A clean pipe surface is essential for the resin to bond properly.

  3. 3.
    Liner Installation

    The resin-saturated liner is pulled or inverted into position inside the pipe, then inflated against the pipe walls using air pressure. The liner conforms precisely to the pipe shape.

  4. 4.
    Curing and Verification

    The resin cures to form a rigid structural lining. A final CCTV inspection confirms the lining is smooth, correctly positioned, and defect-free. You receive before-and-after footage.

Pricing guide

The cost of pipe relining depends on pipe diameter, length and access conditions — short localised repairs are typically the most straightforward, while longer runs or larger-diameter pipes take more work. Relining is often significantly cheaper than excavation once the cost of surface reinstatement is factored in. Request a fixed-price quote online after your CCTV diagnosis.

Trenchless Drain Repairs & Pipe Relining — frequently asked questions

How long does pipe relining last?

A properly installed pipe reline has a design life of 50 years or more. The cured resin liner is resistant to root ingress, corrosion, and chemical attack. We provide a written guarantee on all relining work as standard.

Can all damaged pipes be relined?

Relining is suitable for most pipe damage including cracks, fractures, root intrusion, and displaced joints. However, pipes that have completely collapsed or lost their circular shape may need excavation instead. A CCTV survey determines whether your specific damage is suitable for relining.

Is pipe relining disruptive to my property?

Relining is minimally disruptive. All work is carried out through existing manholes and access points — no digging is required. Your garden, driveway, and landscaping remain untouched. Most relining jobs are completed within a single day.
