External Wall Insulation in Crawley, West Sussex

Most homeowners we speak to in Crawley are tired of watching their energy bills skyrocket. Did you know that up to 45% of a building's heat can escape through uninsulated solid walls? It's literally like throwing cash out the window. When we install an EWI system, we're targeting something called 'thermal bridging'—those annoying cold spots where heat leaks out through the structure. By dramatically lowering the U-value of your walls, we help you keep that expensive heat trapped inside for longer. Whether you're in a Victorian terrace or a post-war semi, the results are usually felt immediately. You'll find yourself reaching for the thermostat less often, and your home's EPC rating will get a healthy boost, which is always a bonus if you ever decide to sell.

We don't believe in cutting corners, which is why we're officially approved contractors for PRB Systems. They're leaders in high-performance renders, and using their materials means we can offer you a finish that's as tough as it is beautiful. Unlike old-fashioned sand and cement renders that can crack and flake, our modern systems—like silicone or monocouche renders—are through-coloured. This means the pigment is mixed right into the render itself, so you'll never have to pick up a paintbrush again. It’s a low-maintenance solution that’s perfect for the coastal-adjacent weather we get here in Sussex. From the initial mechanical fixings of the insulation boards to the final decorative layer, our team handles the whole programme with the kind of precision you’d expect from local experts who care about their reputation.

One of the biggest worries people have about insulation is the mess and the fuss. The beauty of external wall insulation is that, as the name suggests, it’s all done on the outside. You won't have to move furniture, take down curtains, or lose any of your precious internal floor space. We set up our scaffolding, get to work, and leave your interior exactly as it was. It’s a far less invasive process than internal dry lining, and you won't have to deal with plaster dust in your tea for weeks! We pride ourselves on being clean and tidy tradespeople. We’ll protect your garden, your driveway, and your windows, and we always make sure the site is spotless once we’ve finished transforming your Crawley home.
