From the site record
Photographed examples of this service, with the full project scope available in each case study.
Box gutter waterproofing at a retail building in Camberley, with corrosion treatment, pitched roof repairs and new pest proofing. The project covered 60 linear metres of gutter over two weeks.

Commercial gutter lining is a specialist refurbishment that applies a liquid waterproofing membrane inside a suitable existing industrial gutter. The written specification identifies the joints, corners, stop-ends and outlets to be detailed, without necessarily removing the existing gutter.
Local sealant repairs may not address movement across the wider gutter run. A specified lining system bridges joints with a bonded, flexible membrane designed to accommodate movement.
Full gutter replacement can require scaffold, removal of the existing gutter, new manufactured sections, downpipe reconnection and roof-sheet edge re-detailing. Lining retains a suitable existing gutter.
A lining project typically includes inspection and condition survey, specified cleaning and repairs, application of the selected membrane and, where included, testing and photographic records. The written specification confirms the required stages and details.
The programme depends on the specified product, weather, access, gutter condition and scope. The written programme and product system data control sequencing, cure periods and return to service.
Pre-formed GRP gutter liners use rigid sections with sealed joints. Liquid lining forms a continuous bonded membrane and can accommodate varied gutter profiles and geometry without bespoke rigid sections.
The specified lining system and detailing are assessed against the gutter substrate, loading, outlets, corners and stop-ends. The written specification confirms any preparation and access requirements.
Pricing depends on gutter profile, substrate condition, repairs, outlets and access method. We provide a fixed-price written quotation following a free gutter inspection.
The quotation sets out the included preparation, repairs and lining system. Qualifying systems can carry a 20-year guarantee subject to written terms.
01
Specified liquid-applied liners can form a continuous waterproof membrane across suitable gutter sections.
02
Box, valley, parapet and secret gutters may be suitable for lining; the survey confirms substrate and profile suitability.
03
Outlets, downpipes and penetrations are assessed and detailed in the specified lining system where required.
04
Specified repairs can address corroded or damaged gutter sections before lining where the substrate is suitable.
05
The specified finish is assessed alongside gutter falls, outlets and maintenance requirements to support drainage performance.
06
UV-stable coatings are specified to maintain flexibility and waterproofing over the system's service life.
The Advantages
Our gutter lining service delivers lasting results with minimal disruption to your business operations.
From initial survey to final inspection, we follow a proven methodology to ensure quality results every time.
We assess the condition of your gutters, identifying corrosion, blockages, and any structural issues.
Gutters are thoroughly cleaned and any damaged sections are repaired or reinforced.
Multiple coats of liquid membrane are applied with reinforcement at joints and outlets.
Where included in the specification, water testing and photographic documentation record the completed work.
Commercial gutter defects can occur at joints, corners, stop-ends and outlets as sealants degrade, metal corrodes and sections move. Where suitable, a specified liquid lining can form a bonded membrane within the existing channel and detail identified joints and outlets.
Pricing depends on the gutter profile, substrate condition, repairs, outlets and access method. We provide a free gutter inspection followed by a fixed-price written quotation.
Qualifying lining systems can carry a 20-year guarantee, subject to the written terms supplied for the project. The system specification is selected for the gutter substrate, condition and expected movement.
A range of commercial gutter profiles may be suitable for lining, including box, valley, parapet and selected metal or fibre-cement gutters. Our survey confirms whether the gutter type, substrate and condition are appropriate for the specified system.
Yes, where the existing gutter is suitable. We first address specified repairs, clean and prepare the gutter channel, and then apply the lining system. Qualifying systems can carry a 20-year guarantee subject to written terms.
The programme and curing time depend on the specified product, weather, access and scope. The written programme and product system data control the sequencing, cure periods and return to service for each project.
The effect on drainage capacity depends on the specified system thickness, gutter geometry, falls, outlets and existing debris management. These factors are reviewed during survey and reflected in the written specification.
