Drain Patch Repair across Sunderland

A drain patch repair is a targeted repair technique for isolated damage in an otherwise sound pipe. Where a full pipe reline would address the entire length of a drain run, a patch repair applies a short structural resin liner — typically 300mm to 1000mm in length — precisely over the damaged section identified by CCTV survey. This is significantly more cost-effective when the damage is localised: a single cracked joint, a small fracture, or a point of root ingress in an otherwise structurally sound pipe. The patch is installed using the same cured-in-place lining technology as full relining — a resin-saturated carrier is positioned at the defect using a winch and CCTV monitoring, inflated against the pipe wall, and cured to form a rigid structural repair. Once cured, the patch is CCTV verified to confirm it has bonded correctly and sealed the defect. Patch repairs are minimally invasive — all work is carried out through existing manholes and access points with no excavation required. They are suitable for pipes from 100mm to 225mm in diameter in clay, concrete, or plastic. Most patch repairs are completed within a single visit.

Signs you need drain patch repair help

  • ✓ A CCTV survey has identified a single cracked joint or small fracture in otherwise sound pipework
  • ✓ A persistent root intrusion point has been located at a specific joint that requires permanent sealing
  • ✓ You want to repair a drainage defect without the cost of relining the entire pipe run
  • ✓ The pipe section is beneath a conservatory, extension, or hard surface where excavation is not practical
  • ✓ A localised repair is needed as part of a planned property sale or purchase negotiation

Our process

  1. 1.
    CCTV Location

    We survey the affected pipe section to confirm the exact position and size of the defect, measure the repair length required, and assess whether patch repair is suitable for the damage type.

  2. 2.
    Pipe Preparation

    The pipe is cleaned by high-pressure jetting to remove deposits and root fragments from the repair area. A clean pipe surface is essential for the resin to bond correctly.

  3. 3.
    Patch Installation

    The pre-cut, resin-saturated patch carrier is winched into position under CCTV guidance, inflated against the pipe wall at the defect location, and held under pressure while the resin cures.

  4. 4.
    CCTV Verification

    Once cured, a camera pass confirms the patch is correctly positioned, fully bonded, and defect-free. You receive before-and-after footage as part of your documentation.

Pricing guide

Drain patch repairs in the Sunderland area typically cost between £150 and £350 depending on the pipe diameter, access conditions, and length of patch required. Patch repair is considerably more cost-effective than full relining when the damage is genuinely localised. We provide a fixed price following CCTV diagnosis. No call-out fee applies.

Drain Patch Repair — frequently asked questions

How do I know if I need a patch repair or a full reline?

A CCTV survey is the only reliable way to determine which repair is appropriate. If the damage is confined to one or two specific points in an otherwise sound pipe, patch repair is the right solution. If there are multiple defects spread along the pipe run, full relining is more cost-effective. We will always recommend the most economical appropriate repair.

How long does a drain patch repair last?

A correctly installed patch repair using quality resin materials has a design life of 50 years or more — the same as a full reline. The cured resin is resistant to root intrusion, corrosion, and chemical attack. We provide a written guarantee on all patch repair work.

Will a patch repair affect the flow capacity of the pipe?

A well-installed patch repair has minimal effect on pipe flow capacity. The cured liner reduces the internal diameter by only a few millimetres and its smooth internal surface is actually more hydraulically efficient than an aged clay or concrete pipe with rough, deteriorating walls.
