External Wall Insulation in Arundel, West Sussex

Most people we chat with are shocked to learn that up to 45% of a home's heat can escape through uninsulated solid walls. By installing an EWI system, we can drastically lower your property's U-value—that's just a technical way of saying we slow down the rate at which heat leaks out. We use high-quality materials like EPS or Mineral Wool slabs, which are mechanically fixed to your external walls. This doesn't just stop the draughts; it eliminates 'thermal bridging'—those annoying cold spots that often lead to condensation and mould inside your cupboards. It's about more than just saving a few quid on the gas bill; it's about making your home a genuinely comfortable place to be.

We don't just slap some boards on the wall and call it a day. As approved PRB Systems contractors, we're trained to use some of the best rendering products on the market. Once the insulation layer is secure, we apply a beautiful, through-colour silicone or monocouche render finish. Because the colour is built right into the render, you won't have to worry about the paint peeling or having to get the ladders out every few years. It's low-maintenance, highly breathable, and provides essential coastal weatherproofing against the damp Sussex air. Your house won't just be warmer; it'll look like a brand-new build, significantly boosting its kerb appeal and potentially its value too.

One of the biggest worries homeowners have about insulation is the disruption. If you go for internal dry lining, you're looking at moving furniture, losing floor space in every room, and dealing with weeks of dust. EWI is different. Because all the work happens on the outside, you can keep living your life indoors exactly as normal. Our team is known across Portslade and Arundel for being tidy and respectful. We take care of your garden, protect your windows, and ensure the site is left spotless. It's a straightforward way to improve your EPC rating and tackle fuel poverty without having to redecorate your entire house from top to bottom.

Living near the coast means our homes take a bit of a beating from the wind and rain. If your current render is cracked or blown, you might already be dealing with penetrating damp. Our EWI systems act as a robust barrier, protecting your building fabric from the elements. We’re fully insured with £1m Public Liability cover and have spent over a decade perfecting our craft across the Sussex coast. Whether you're in a conservation area near the Castle and need advice on planning, or you're in a more modern home in the Arun valley, we've got the expertise to help.
