Upgrade your Horsham home with durable silicone rendering

Have you ever looked at your house and felt like the exterior was letting the side down? Maybe you're tired of seeing those hairline cracks reappear every spring, or perhaps you're simply fed up with the endless cycle of repainting every few years. Living in a market town like Horsham, our homes have to stand up to a fair bit of West Sussex weather, and traditional sand and cement render often struggles to keep up. That's where silicone rendering comes in. It is a modern, high-performance solution that doesn't just make your property look brand new—it actually protects it from the elements. We've spent years helping homeowners across the area, from the leafy streets near Horsham Park to the newer developments on the outskirts, transform their properties with a finish that's built to last.

Why Choose Our Silicone Rendering in Southwick?

Benefits of choosing through-colour silicone finishes

One of the most common questions we get asked is what makes silicone render so special compared to the old-fashioned stuff. The real 'magic' is that it's through-coloured. This means the pigment is mixed right into the render itself, so you'll never have to pick up a paintbrush again. If it gets a little scratch, you won't see a different colour underneath. Beyond the aesthetics, it's incredibly flexible. While traditional render is rigid and prone to cracking when the ground shifts or temperatures change, silicone render has 'elasticity' that allows it to move with your building. It is also highly breathable, which is vital for preventing that dreaded internal damp by allowing moisture vapour to escape from your walls while keeping the rain firmly out.

Weatherproof protection for Horsham and West Sussex properties

We all know how unpredictable the weather can be in our corner of the country. Our silicone rendering systems are specifically designed to be hydrophobic—which is just a fancy way of saying they repel water. Instead of soaking into your brickwork, rainwater simply beads up and rolls off, often taking surface dirt along with it. This self-cleaning quality keeps your home looking fresh even after a stormy Sussex winter. Whether you own a Victorian terrace in the town centre that needs a sympathetic update or a modern detached house in Broadbridge Heath looking for a sleek finish, our rendering provides a robust shield that maintains its vibrant look for 15 to 25 years with very little maintenance on your part.

Certified PRB Systems contractors for guaranteed quality

We don't believe in cutting corners, which is why we are officially approved installers for PRB Systems, one of the leading names in high-performance renders. This isn't just a badge for us; it means we've been trained to apply these materials to the highest possible standards, ensuring you get the full benefit of the manufacturer's technology. We also know that having tradespeople at your house can be stressful, so we make a point of being the kind of team you'd actually want around. We're fully insured with 1 million public liability cover, and we take real pride in our 'clean and tidy' reputation. We treat your driveway and garden with respect, making sure we leave your property looking better than we found it.

Simple rendering process with professional results

You might be wondering what actually happens when we start a project. We don't just slap a bit of plaster on the wall; it's a careful, multi-stage process. After preparing the 'substrate' (your existing walls), we apply a high-quality base coat and embed a specialist mesh. This mesh acts like a skeleton, giving the wall incredible strength and further preventing cracks. Finally, we apply the silicone top coat in the colour of your choice. It creates a flawless, modern finish that instantly boosts your home's kerb appeal. Many of our Horsham clients are surprised at how quickly the transformation happens, often taking their home from dated to the best-looking house on the street in just a matter of days.

FAQ

Frequently Asked Questions

Answers to common questions about our silicone rendering and external wall insulation services in Southwick and across Portslade, Brighton & Worthing.

What Exactly Is Silicone Rendering and Why Is It Popular in Southwick?

+

If you have been walking around Southwick lately, you might have noticed many homes looking remarkably clean and modern. Most of that is down to silicone rendering. Unlike the old-fashioned sand and cement finishes that tend to crack or look tired quickly, silicone render has the water-repellent material mixed right into it. It creates a breathable surface that lets moisture escape from your walls while stopping rain from getting in. Because it is a through-colour render, the pigment goes all the way through the mix. This means if the surface gets a small scratch, you won't see a different colour underneath, and you can say goodbye to the chore of repainting your house every few years.

How Does Through-Colour Rendering Stand Up to the Southwick Sea Air?

+

Living on the Sussex coast in the Adur district means your property has to deal with plenty of salt, wind, and driving rain. Standard exterior wall finishes often struggle in these conditions, leading to damp patches and unsightly cracks. Silicone systems are much more flexible than traditional alternatives. They can handle the tiny natural movements of your house without splitting. This flexible render acts as a high-performance weatherproof coating that keeps the West Sussex weather on the outside where it belongs. It is a smart choice for anyone in Southwick who wants a finish that stays looking sharp regardless of the coastal climate.

Can I Combine New Rendering with External Wall Insulation?

+

If your home feels a bit draughty or you are worried about rising energy costs, we can certainly help. Before applying the final silicone or monocouche finish, we can install a layer of external wall insulation. This is essentially like wrapping your home in a high-tech thermal blanket. It stops heat from escaping through the brickwork, which helps keep your rooms warmer in the winter and cooler in the summer. For many people in the local area, combining insulation with a fresh rendering job is the most effective way to improve their home's energy rating and kerb appeal at the same time.

Why Do You Use PRB Systems for Your Southwick Rendering Projects?

+

At Portslade Plastering, we believe the quality of the job is only as good as the materials we use. That is why we are approved installers for PRB Systems. They are industry leaders in high-performance renders that are built to last. Whether we are applying a thin-coat silicone finish or a one-coat monocouche render, these products give us a much better finish than the cheaper brands you might find elsewhere. It allows our team of West Sussex plasterers to give you a result that is durable, looks fantastic, and adds real value to your property.

How Much Maintenance Do These Exterior Wall Finishes Really Need?

+

One of the biggest questions we get from homeowners in Southwick is about upkeep. The great thing about silicone rendering is that it is incredibly low maintenance. Because the surface is so good at repelling water, dirt and algae find it much harder to take hold. Most of the time, a quick spray with a garden hose once a year is all you need to keep it looking brand new. You won’t have to deal with the constant cycle of scraping, priming, and painting that comes with older properties. It gives you more time to enjoy your home rather than constantly working on it.
