Industrial Drainage Solutions
Gutter Lining
Eliminate persistent gutter leaks with our seamless liquid gutter lining systems. We transform failing industrial gutters into watertight drainage channels - without the cost and disruption of replacement.
What is commercial gutter lining?
Commercial gutter lining is a specialist refurbishment that installs a seamless, fully bonded liquid waterproof membrane inside an existing industrial gutter, bridging every joint, corner, stop-end, and outlet to create a continuous watertight channel. It eliminates the joint and outlet leaks that cause 90% of commercial gutter failures, without removing the existing gutter. Lining systems carry 20-year guarantees and typically cost half to one-third of full gutter replacement.
Why Lining Beats Sealant Repairs and Replacement
Sealant repairs at gutter joints fail within one to three years because the underlying joint continues to move with thermal expansion and the sealant simply cannot keep up. Lining solves this permanently by bridging every joint with a fully bonded, flexible membrane that moves with the gutter rather than against it.
Full gutter replacement requires scaffold, removal of the existing gutter, new manufactured sections, downpipe reconnection, and often roof sheet edge re-detailing, typically two to three times the cost of lining for the same waterproofing outcome.
Our 4-Stage Lining Process
Every lining project follows a four-stage process: full inspection and condition survey, deep cleaning with any necessary structural repairs, application of a fleece-reinforced liquid membrane bonded continuously through the channel and all outlets, then final water testing with photographic sign-off.
Most commercial gutter runs complete in two to five days depending on linear metres and complexity. The work is low-disruption, requires no internal building access, and the gutter is fully functional within hours of completion as the membrane cures.
Lining vs Replacement vs GRP Liners
Pre-formed GRP gutter liners are dropped in as rigid sections and rely on sealant at every joint between liner sections, replicating the original failure mode. Liquid lining is one continuous bonded membrane with zero joints, providing significantly longer guaranteed life and accommodating any gutter profile or geometry without bespoke manufacture.
Liquid lining also adds zero structural loading, requires no removal of the existing gutter, and integrates fully with all outlets, internal corners, and stop-ends, eliminating the bespoke-fabrication delays that affect both GRP and full replacement projects.
What Does Commercial Gutter Lining Cost?
Commercial gutter lining typically costs £60–£150 per linear metre depending on gutter profile, substrate condition, and access method. For a 200m perimeter industrial unit this equates to £12,000–£30,000, versus £40,000–£80,000 for full replacement of the same length.
Pricing is fixed following our free gutter inspection and includes any structural repairs, deep cleaning, the lining system itself, and a 20-year guarantee. Most projects are completed without scaffolding using rope access or MEWP, further reducing total cost.
Key Features
Seamless Liners
Our liquid-applied gutter liners create a continuous waterproof membrane with no joints or seams to fail.

Common Questions
Why do commercial gutters need lining?
Commercial gutters fail most commonly at joints, corners, stop-ends, and outlets, where sealants degrade, metal corrodes, and sections pull apart under thermal movement. Liquid lining creates a seamless, fully bonded waterproof membrane inside the existing channel, bridging all joints and sealing all outlets so there are no weak points left to fail.
How much does commercial gutter lining cost?
Commercial gutter lining typically costs £60–£150 per linear metre depending on the gutter profile, substrate condition, and access method. This compares very favourably with full gutter replacement, which requires scaffold, removal, new materials, installation, and downpipe reconnection, often costing two to three times as much for the same running length.
How long does commercial gutter lining last?
Our lining systems are guaranteed for 20 years via a guarantee. The liquid membrane we use is UV-stable, frost-resistant, and flexible enough to accommodate the thermal movement in long commercial gutter runs. With gutters kept clear of debris, the lined system reliably performs for the full guaranteed period and often beyond.
What types of commercial gutter can be lined?
We can line all standard commercial gutter profiles, including cast iron half-round and ogee sections, pressed steel industrial box gutters, valley gutters between parallel roof pitches, parapet gutters behind brick copings, fibre cement gutters, and aluminium fascia-mounted systems. Our survey will confirm the appropriate lining system for your specific gutter type and substrate.
Can you line gutters that are already leaking?
Yes, in most cases. We first repair any structural damage or significant corrosion, clean the gutter channel thoroughly, and then apply the lining system. This is far more cost-effective than replacing the entire gutter, and the lined gutter then carries a 20-year guarantee.
How long does gutter lining take?
Most commercial gutter lining projects are completed within two to five days depending on the total gutter run length and complexity. The lining cures within a few hours, so the gutter is fully functional the same day. The work is low disruption, no building access is required and no significant noise is generated.
Will gutter lining reduce drainage capacity?
No. The lining is typically only 2–3mm thick and creates a smoother internal surface than the original gutter channel. This can actually improve flow rates by reducing surface friction and eliminating the rough edges at corroded joints that trap debris and restrict flow.
