Your Local Silicone Rendering Specialists
Render Group SW Ltd are based in Llanbradach — right in the heart of Caerphilly borough. That matters because we understand the properties here in a way that companies travelling in from further afield simply don't. The Caerphilly area has a genuinely varied housing stock: rows of Victorian terraces climbing the valley sides, inter-war semis on the flatter ground, the big 1960s and 1970s estates that ring most of the town centres, and a growing number of newer-build developments. Each era of construction brings its own quirks, and knowing what you're likely to find behind the existing finish before you even start is something that only comes with experience in the area.
South Wales gets a lot of rain — that's no secret. Caerphilly borough in particular sits in a position where westerly weather systems roll in off the Atlantic with very little to slow them down. That persistent dampness, combined with the temperature fluctuations you get through a typical Welsh winter, puts real pressure on exterior walls. Surfaces that aren't properly protected can allow water to penetrate brick and block, leading to issues like damp, frost damage, and deteriorating pointing. Silicone render is one of the most effective solutions we know of for this climate: the hydrophobic surface causes water to bead and run off rather than soak in, and the flexible nature of the system means it can handle the minor thermal movement that causes more rigid renders to crack over time. Because it's also vapour-permeable, any residual moisture in the wall can still escape — you're not sealing a problem in, you're giving the wall proper protection while letting it breathe.
Where We Work in Caerphilly Borough
We cover the full Caerphilly borough and carry out silicone rendering work regularly across all the main towns and villages. That includes Llanbradach, Caerphilly town itself, Bedwas, Risca, Ystrad Mynach, Hengoed, Aberbargoed, and Bargoed, as well as the many smaller communities between them. Being locally based means there's no call-out charge for surveys within the borough, and we're not trying to fit a Caerphilly job around work in another region — when we're here, we're focused on the job in front of us.
How We Approach a Silicone Rendering Project
Every job starts with a proper survey. We come out, look at the existing surface, assess whether there's any existing render that needs to come off, check for cracks or areas of concern in the substrate, and talk through colour options with you. We use a colour-matching system so you can see how different shades will look before any commitment is made. Once you're happy and we have an agreed start date, the preparation work begins — which is often the most time-consuming part of the process. Old render that's blown or de-bonded has to be hacked off; the wall behind needs to be sound before anything new goes on. We apply a reinforcing mesh embedded in a base coat before the silicone top coat goes on, which significantly improves impact resistance and reduces the risk of cracking. When the render is finished we clean the site and make sure any surrounding surfaces are as we found them.
