Why Choose Our Silicone Rendering Services?

Why Silicone and Monocouche Systems Lead the Market

Modern rendering has moved beyond traditional sand and cement, which often cracks and suffers from unsightly algae growth in humid conditions. Our through-coloured silicone and monocouche systems are flexible, meaning they move with your building to prevent hairline fractures. These products are available in a vast array of colours and textures, including the popular K Rend finish, offering a clean, contemporary look that revitalises any exterior. By acting as a protective barrier, these systems also help reduce heat loss, contributing to a warmer home and lower energy bills.

Can Rendering Improve My Property EPC Rating

Yes, high-quality external rendering is a vital component of energy-efficient home improvements. When installed as part of a wider insulation strategy, render significantly improves the thermal envelope of your building. This is particularly effective for non-traditional builds, including Cornish units and Wimpey no-fines properties, which often struggle with thermal efficiency. We work closely with landlords and homeowners to ensure our projects align with MEES compliance and help boost your EPC rating. Investing in professional rendering is a practical step toward long-term property decarbonisation.

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.
