Drain lining, also referred to as pipe relining or sewer lining, is a no-dig method of repairing damaged drainage pipes from the inside. Rather than excavating to access the pipe, a resin-coated sleeve is inserted and cured in place, creating a new inner lining that seals cracks, closes joints, and restores the structural integrity of the pipe. It’s suitable for a range of defects including cracks, root ingress, displaced joints, and general deterioration, and in most cases can be completed in a single visit with minimal disruption to the surrounding area.
Why choose us for drain lining in London?
When a drain survey reveals cracks, displaced joints, root ingress, or structural deterioration, the natural concern is what fixing it will involve. Excavation is disruptive, costly, and in many London properties, logistically complicated. In the majority of cases, it isn’t necessary.
Drain lining is a no-dig repair method that reinstates damaged pipework from the inside, without breaking up driveways, gardens, or floors. It’s suitable for a wide range of defects and, when carried out correctly, provides a durable, long-lasting repair that extends the working life of the pipe significantly.
All of our engineers are fully certified in drain lining and use only approved materials, so you can be confident the repair meets the required standards. We carry out a CCTV survey before any lining work begins to confirm the extent of the damage and ensure the method is appropriate, and we use camera inspection throughout the process to verify the result.

How does drain lining work?
Before lining begins, we carry out a CCTV survey to assess the condition of the pipe and identify exactly where the damage is. The pipework is then cleaned using high-pressure water jetting to ensure the internal walls are clear and ready to receive the lining.
A flexible sleeve coated with a chemical resin is inserted into the damaged section of pipe and inflated so it sits tightly against the pipe wall. The resin is then cured using hot water or UV light, hardening the sleeve into a smooth, structurally sound inner lining. Once cured, the inflated liner is removed, leaving a relined pipe ready for use.
For localised damage, patch lining allows us to target a specific section rather than relining the entire run. This is particularly effective for displaced joints, cracked sections, or damaged rest bends where the surrounding pipework is otherwise in good condition.
Frequently Asked Questions
How much does drain lining cost?
The cost depends on several factors: the diameter of the pipe, the length of the section being lined, the condition of the pipework, and whether any preparatory work such as jetting or descaling is required beforehand.
A CCTV survey is carried out prior to lining, which adds to the overall cost but ensures the work is targeted and carried out efficiently. As a general guide, no-dig lining and patch repairs typically fall within the range of £600 to £2,500 or more depending on the scope.
We’ll assess the situation and provide a clear, itemised quote before any work begins, with a straightforward explanation of what’s included and what’s driving the cost.

What are the benefits of drain lining?
The most immediate benefit is avoiding excavation. In London, where access is often constrained by driveways, paving, landscaping, or proximity to other structures, not having to dig is a significant practical advantage.
Drain lining is faster than traditional repair methods, causes considerably less disruption to occupants or operations, and typically costs less than excavation once groundwork and reinstatement are factored in.
The finished lining is smooth, resistant to root ingress, and designed to last for many years. For properties with older pipework that shows signs of deterioration in multiple areas, it also provides a practical route to addressing several defects in a single visit.
