External Wall Insulation in Horsham, West Sussex

Does your property have solid walls? If it was built before the 1920s, the chances are it does not have a cavity that can be filled with standard insulation. This is where External Wall Insulation really shines. By fixing a layer of high-quality insulation boards—like EPS or Mineral Wool—to the outside of your brickwork, we create a continuous thermal barrier. This process drastically lowers your property's U-value, which is just a technical way of saying it stops heat from leaking out. We pay close attention to thermal bridging, making sure those pesky cold spots around windows and corners are completely eliminated. It is a game-changer for Horsham residents looking to improve their property's EPC rating and overall comfort.

We believe in doing things right the first time, which is why we are proud Approved PRB Systems Contractors. When we work on your Horsham home, we are using premium, high-performance renders that are designed to last. These systems are not just about warmth; they provide incredible coastal weatherproofing against the unpredictable Sussex weather. Because the render is through-coloured, you will not have to worry about the paint peeling or having to get the ladders out every few years for a refresh. It is a low-maintenance, durable solution that protects the very structure of your building from damp and driving rain.

Let's be honest, we all want our homes to look great. Beyond the massive energy savings, EWI completely refreshes the look of your house. We offer a variety of finishes, from Silicone Render to Monocouche, available in a wide range of colours. Imagine your tired or cracked exterior being replaced with a crisp, modern, and clean finish that makes it look like a brand-new build. Many of our Horsham customers are amazed at how much a professional EWI installation increases their property's aesthetics and market value. It is the ultimate home improvement that pays for itself through lower heating bills and a much more attractive exterior.

One of the biggest questions we get is, "How much mess will there be?" The beauty of External Wall Insulation is that all the work happens outside. Unlike internal insulation, we do not need to move your furniture, take down your radiators, or mess up your skirting boards. You do not lose a single centimetre of floor space inside your rooms, which is a huge plus in smaller properties. Our team prides itself on being tidy and respectful; we treat your property like it is our own, ensuring the site is kept clean throughout the process. We have been helping neighbours across the Horsham area for years, and we know how important it is to keep your daily life running smoothly while we work.
