Why Choose Our Silicone Rendering Services?

Why Choose Through-Coloured Render for Your Home

Traditional sand and cement renders often crack or lose their appeal over time. In contrast, our silicone-based systems are designed to be flexible, which allows them to withstand minor building movements without developing unsightly fissures. Because the colour is integrated into the material itself, there is no need for regular painting, saving you significant maintenance effort and cost. These advanced coatings are breathable, allowing moisture to escape from your walls while preventing rainwater from penetrating, which is essential for preserving the health of your masonry.

How Our Rendering Process Enhances Energy Efficiency

Modern rendering is not just about aesthetics; it is a vital component of home energy efficiency. By applying our high-performance silicone render systems, we help improve the thermal performance of solid walls, which are common in many Victorian and terrace properties found throughout Merthyr Tydfil. This creates a more stable internal temperature and helps to combat issues like thermal bridging and damp. Our process adheres to strict PAS 2030 standards, ensuring that every project we undertake contributes to a warmer home and lower energy bills.

What Property Types Benefit from Silicone Rendering

Whether you live in a classic Victorian terrace, a mid-century semi-detached house, or a non-traditional build, our rendering solutions are tailored to suit your specific structure. We have extensive experience working on diverse building types, providing bespoke finishes that respect the architectural character of your home while delivering the modern benefits of K Rend and other leading materials. If you own an HMO or a commercial building, we also ensure our work complies with the necessary energy efficiency standards to keep your property compliant and desirable.

What Our Clients Say About Global Plastering

"Excellent work the team removing our old 1970's cladding and replacing it with insulation and a rendered finish. The job went smooth from start to finish with all old materials removed from site. We are very pleased with the end result and would thoroughly recommend Global Plastering."

A. Jenkins (Ferndale)

"Dilwyn and his team were brilliant and made a lovely job of our EWI. They were very friendly, hard-working, and left no mess at the end of each day. Our house looks great and we can definitely feel the benefits of the insulation already. I'm very glad we chose EWI especially with energy costs as they are now."

G. Toogood (Bristol)

"Charlotte and the team were professional, reliable, and excellent at communicating throughout. They did a fantastic job of skimming and rendering the back of our house during our renovation. Superb quality of work and highly recommended!"

M. Lewis (Cardiff)

FAQ

Frequently Asked Questions

Answers to common questions about our expert silicone rendering and external wall finishes in South Wales and South West England and across South Wales.

How long does silicone rendering actually last?

+

When applied correctly by a professional team, silicone render systems are designed to last 25 to 30 years or more. Because the colour is through-and-through, it won't flake or peel like paint, and its flexible nature prevents the cracking often seen in older render types.

Can I put silicone render over my existing render?

+

In many cases, yes, but it depends on the condition of the current surface. If your old render is "blown" or falling off, we will need to remove it first to ensure the new system has a solid foundation. We always carry out a full site survey to determine the best course of action for your specific walls.

Is silicone rendering expensive compared to sand and cement?

+

The initial cost is higher than traditional sand and cement, but it offers much better value over time. You save money because you don't need to repaint every few years, and the added weatherproofing and thermal benefits can help lower your heating costs. It is an investment in the long-term health and appearance of your property.

Does silicone render help with damp?

+

Yes, silicone render is excellent for tackling penetrating damp. By creating a waterproof but breathable barrier, it stops rainwater from soaking into your masonry while allowing internal moisture to evaporate. However, if you have rising damp, that is a separate issue that needs to be addressed before rendering begins.
