Why Choose Our External Wall Insulation Services Across South Wales?

Why choose EWI for your Clevedon home?

Many older properties in the North Somerset area suffer from poor thermal efficiency, leading to cold walls, condensation, and expensive heating bills. External wall insulation acts like a thermal blanket for your home, wrapping it in high-performance materials that stop heat from escaping through your masonry. By addressing thermal bridging at the source, we help you eliminate cold spots and significantly reduce your reliance on central heating. This process is particularly effective for solid wall structures that were never designed to hold heat, offering an immediate improvement in your living environment.

Our installation process for North Somerset buildings

We follow a meticulous, code-compliant approach to every project we undertake in Clevedon. First, we conduct a thorough survey to understand your property type, current wall condition, and ventilation requirements. We then apply high-performance insulation boards, which are secured to your existing brickwork. The final finish involves a durable, weather-resistant render—such as silicone or K Rend—which comes in a wide range of colours and textures. This ensures your home looks as good as it feels, all while maintaining the breathability required for long-term structural health.

Can external insulation improve your EPC rating?

Absolutely. Improving the thermal envelope of your property is one of the most effective ways to upgrade your EPC rating. For landlords in Clevedon and the wider North Somerset region, meeting the latest MEES compliance standards is essential for renting out properties. By investing in our PAS-accredited insulation services, you are not only lowering your carbon footprint but also adding tangible value to your building. We ensure that all our work is fully documented and compliant, giving you the peace of mind needed for property certification.

Committed to quality and long-term peace of mind

As a company deeply rooted in the South West, we pride ourselves on delivering workmanship that meets the highest national standards. Every EWI installation we complete is backed by SWIGA insurance-backed guarantees, providing you with long-term protection and assurance. Our team is fully insured and licensed, ensuring every project is managed safely and professionally from start to finish. If you are ready to transform your home with a warmer, more energy-efficient finish, get in touch with our team today.

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!"

Expert Advice

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited external wall insulation, solid wall solutions, and energy efficiency services in South Wales and South West England and across South Wales.

Will EWI make my home look different?

+

Yes, but in a good way. You can choose from a wide range of silicone renders or even brick-slip finishes. If you live in a Victorian street, we can often match the aesthetic of the surrounding area while vastly improving the thermal performance.

How long does the installation take?

+

For a standard semi-detached house, the work usually takes between two and three weeks, depending on the weather. Because all the work happens outside, there is very little disruption to your daily life.

Do I need planning permission for external insulation?

+

In most cases, EWI falls under permitted development. However, if your home is a listed building or in a conservation area, you might need permission. We can advise you on the specific rules for your location in South Wales.

Can I get a grant for external wall insulation?

+

There are often government schemes available to help with the costs of energy efficiency improvements, especially for those in fuel poverty or living in certain postcodes. We can help you find out if there is any current funding available for your project.

Is EWI better than internal wall insulation?

+

EWI is generally preferred because it doesn't take up any floor space inside your rooms and it does a better job of covering thermal bridges (areas where heat escapes through the structure). It also protects the exterior fabric of your building from the elements.
