Why Choose Our External Wall Insulation Services Across South Wales?

How Our Rhondda EWI Installation Process Works

Our process begins with a professional retrofit assessment to understand the specific needs of your building. Whether you live in a traditional Victorian terrace or a non-traditional build like an Airey or Wimpey no-fines property, we tailor our approach to ensure optimal results. We clean and prepare your exterior walls before securely fixing the insulation boards. These are then finished with a high-quality, weather-resistant render. This not only traps heat effectively but also provides a fresh, modern aesthetic to your property exterior.

Why Should You Consider Solid Wall Insulation?

Investing in external wall insulation is one of the most effective ways to lower your energy bills and stop heat from escaping through your walls. Beyond the financial savings, you will notice a drastic improvement in thermal comfort during the colder months, eliminating those persistent draughts and cold spots. For landlords and property owners in the Rhondda, our service is a vital step toward improving EPC ratings and ensuring your building meets current MEES compliance standards for energy efficiency.

Professional Standards and Trusted Guarantees

At Global Plastering, we pride ourselves on being a PAS 2030 compliant contractor, ensuring that every project adheres to rigorous national retrofit standards.

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!"

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.
