External Wall Insulation
in Southwick & Portslade, Brighton & Worthing
Energy efficient EWI specialists and approved PRB Systems contractors.

Most homeowners we speak to in Southwick are fed up with the constant cycle of energy price hikes. If your property was built before the 1920s, it probably has solid walls rather than cavity walls, meaning there’s no gap to fill with traditional insulation. This is where EWI really shines. By fixing high-performance insulation boards—like EPS or Mineral Wool—directly to your external walls, we drastically lower your home's U-value (the rate at which heat escapes).But it's not just about the numbers on your EPC. By eliminating 'thermal bridging'—those annoying cold spots that lead to condensation and black mould—you're creating a much healthier environment for your family. Imagine waking up on a frosty January morning and not needing to immediately dive for the thermostat. That's the difference a professionally installed EWI system makes.

We know that choosing someone to work on your home is a big decision. You want to know the job’s being done right, especially with the coastal weather we get here in Sussex. That’s why we’re proud to be Approved PRB Systems Contractors.

When you call us, you're talking to tradespeople who take genuine pride in their craft and their reputation within the Portslade and Southwick community.

One of the best things about External Wall Insulation is the 'good as new' finish it gives your home. If your current brickwork is looking a bit tired, or your old render is cracking and letting in damp, EWI solves two problems at once. Once the insulation boards are mechanically fixed and meshed, we apply a beautiful, through-colour render. Because we use advanced materials like silicone render, you’ll benefit from a finish that is highly flexible (meaning no more unsightly cracks) and breathable. The best part? These renders are through-coloured, so you can put the paintbrushes away for good. Whether you want a crisp, modern white or a softer coastal tone, your home will be the envy of the street. It’s an investment that not only saves you money on bills but also adds significant value to your property.

A common concern we hear is, "How much mess will this make?" The beauty of EWI is that it's a non-invasive process. Unlike internal insulation, which requires moving radiators, skirting boards, and kitchen units, all our work happens outside. You can go about your daily routine while we work on the exterior of your property. We take great care to protect your garden, windows, and driveways, and we make sure the site is kept clean and tidy throughout the project. From the initial over-boarding to the final scrape of the monocouche render, we keep you informed every step of the way. If you’re in a conservation area or a listed building in Southwick or Brighton, we can also offer advice on local planning considerations to ensure your project goes off without a hitch.
