Keep Southwick homes toasty while slashing energy bills

Have you noticed how some of the older houses around Southwick Green always seem a bit chilly, no matter how high the heating is cranked up? If you live in one of our area’s beautiful period properties, the chances are you have solid walls rather than modern cavity walls. This means there’s no gap to blow insulation into, and you're essentially losing about 45% of your heat right through the brickwork. It feels like you're trying to heat the entire Sussex coast sometimes, doesn't it? That’s where External Wall Insulation, or EWI, comes in. Think of it as wrapping your home in a high-quality thermal duvet that keeps the warmth in and the coastal damp out.

Why Choose Portslade Plastering for External Wall Insulation in Southwick?

Stop throwing money out of the window with EWI

We've all felt the pinch of rising energy prices lately, and watching your hard-earned money vanish through thin walls is frustrating. By installing a professional EWI system, we can drastically lower your property's U-value—that’s just a technical way of saying we stop heat from escaping. Most homeowners we chat with in Adur are amazed at the difference it makes; not only does the house stay warm long after the heating goes off, but your EPC rating gets a significant boost too. This isn't just about comfort; it's a smart investment that pays for itself through lower fuel bills and adds real value to your home.

Transform your exterior with a maintenance-free finish

One of the best things about EWI is that it isn't just a hidden upgrade. Because we finish the insulation with advanced PRB Systems renders, your home gets a complete facelift at the same time. Gone are the days of cracked masonry or peeling paint that needs touching up every couple of years. We use through-colour silicone renders that are incredibly flexible and breathable. They’re designed to withstand the salty Southwick air and wind-driven rain without cracking. You can pick a fresh, modern colour that stays looking ‘good as new’ for years, meaning you can finally put the paintbrush away for good.

Professional EWI installation with zero internal mess

Are you worried about the disruption of a big home improvement project? The beauty of external insulation is exactly that—it’s all on the outside. We won't be tearing up your floorboards or making a mess of your living room. Our team works efficiently from the exterior, fixing high-performance insulation boards like EPS or mineral wool directly to your walls before applying the reinforced base coats and decorative finish. We're proud to be Approved PRB Systems Contractors, which means we’ve been specifically trained to install these materials to the highest possible standards. We’ll treat your property with the respect it deserves, keeping the site tidy and ensuring the 'thermal bridging'—those pesky cold spots—are completely eliminated.

Trust your local Southwick insulation specialists

Choosing the right team is vital when you're making a big change to your property’s structure. We aren't a faceless national firm; we’re local tradespeople who know the specific challenges of West Sussex homes, from Victorian terraces to 1930s semis. We carry £1 million in Public Liability Insurance for your peace of mind and handle everything from the initial survey to the final clean-up. If you're in a conservation area or have a listed building near the harbour, we can even offer advice on local planning expectations. Why not give us a call on 01273 957212 for a friendly, no-obligation chat? We'll pop round, take a look at your walls, and provide a clear, transparent quote to help you start saving on your energy bills.

FAQ

External Wall Insulation FAQs

Answers to common questions about our energy-efficient External Wall Insulation (EWI) and rendering services in Southwick and across Portslade, Brighton & Worthing.

How long does new plaster take to dry?

+

It usually takes about three to five days, but this depends on the weather and how much air is moving through the room. You will see the plaster change from a dark wet look to a light, uniform pink. It is best to wait until it is completely light pink before you start painting.

Do I need to clear the room before you start?

+

It helps if the room is as empty as possible so we have space to work and move our ladders safely. We always bring plenty of heavy-duty dust sheets to protect your floors and any large bits of furniture that cannot be moved.

Can you plaster over my old Artex ceiling?

+

Usually, yes. We can either scrape back the high points and skim over it, or if the texture is very deep, we might suggest over-boarding it with new plasterboard first. We will check the condition of the ceiling and give you the best advice for a long-lasting finish.

What is the benefit of a PRB render system?

+

PRB systems are designed to be flexible and breathable. In coastal areas like Worthing and Portslade, this is very important because it helps prevent cracks and stands up to the salt air much better than traditional materials. Plus, because they come in various colours, you won't need to paint them.

How do I know if I have rising damp or just condensation?

+

Rising damp usually leaves a tide mark on the lower part of the wall, often with some salt staining or peeling wallpaper. Condensation usually shows up as black mould in corners or behind furniture where air does not move. We can come out, take a look with a moisture meter and tell you exactly what is going on.

Is your work guaranteed?

+

We take huge pride in what we do. If there is ever an issue with the workmanship, we will come back and make it right. Our use of high-quality materials also means the finish is built to last for many years.
