External Wall Insulation in Shoreham-By-Sea, West Sussex

Most homeowners we chat with in Adur are looking for two things: a warmer house and lower energy bills. It is a simple fact that around 45% of heat loss in older homes happens through the walls. By installing a professional EWI system, we can drastically lower your property's U-value (that is the technical measure of how much heat you're losing). We use top-tier materials like EPS (Expanded Polystyrene) or Mineral Wool boards, which are mechanically fixed to your outer walls. The result? A home that stays toasty and warm in the winter and surprisingly cool during those rare Sussex heatwaves. Plus, with energy prices remaining a major concern, improving your EPC rating isn't just about comfort; it is a smart financial move that adds real value to your property.

Living so close to the sea means our homes take a bit of a beating from salt spray and driving rain. Traditional sand and cement renders often crack under the pressure, leading to dreaded penetrating damp. As Approved PRB Systems Contractors, we don't just slap on some insulation; we finish it with advanced silicone or monocouche renders. These are 'through-colour' systems, meaning the pigment is mixed right in. You will never have to pick up a paintbrush again! These finishes are incredibly flexible, which prevents the cracking you see on older Shoreham houses, and they are specifically designed for coastal weatherproofing. Whether you want a crisp, modern white or a softer, traditional tone, your home will look 'good as new' for decades.

One of the biggest worries people have about insulation is the disruption. Are you going to have to move all your furniture or live in a building site for weeks? The beauty of External Wall Insulation is that it’s all done from the outside. We don't need to touch your interior decor, and you won't lose an inch of floor space inside. Our team is known across West Sussex for being clean and tidy—we treat your property like it's our own. We'll set up the scaffolding, get the boards fixed, apply the reinforced base coat, and finish with a stunning render. We even handle the tricky bits like extending windowsills and moving downpipes. You just sit back and wait for that first energy bill to arrive to see the difference.
