The difference we deliver
Natural cork thermal coating
Our cork-based coating adds insulation as well as protection.
Flexible, crack-resistant finish
The coating moves with your property, helping prevent hairline cracks.
Carefully clean down after every job
We protect your property properly and leave it tidy once done.
A smarter way to protect your exterior walls
We apply Corksol Spray Cork Systems to help you insulate, protect, and refresh exterior walls without the bulk of traditional render. Made from natural cork, this spray-applied coating creates a breathable finish that helps reduce heat loss while resisting rain and everyday weathering. Its flexible surface moves with your property, which helps prevent the hairline cracking that can spoil older rendered walls.
We've spent 25 years working on property improvements, and Kerrigan Developments knows how to match the right system for the condition of your walls. If you'd like to compare it with our full range, our rendering overview covers every system we offer. You get an exterior that looks cleaner, feels more modern, and keeps working hard long after the job is done.

Two systems to suit the condition of your walls
Our full basecoat system is ideal when walls are tired, uneven, or already cracking, because we remove loose material first and then build a stronger surface with a K Rend high polymer basecoat and embedded mesh. That gives the Corksol top finish a solid foundation and a smooth appearance that lasts. If your existing render or painted finish is still sound, we can use an overspray system with light preparation and minor crack repairs instead of stripping everything back.
This route is often a practical way to improve appearance and thermal performance with less disruption. If a two-layer build-up suits your walls better, our spray cork render system covers that approach instead. Kerrigan Developments provides full property protection and a clean down, so we respect your home from start to finish.
