Why Choose Our External Wall Insulation Services Across South Wales?

How Our External Wall Insulation Systems Work

Our installation process begins with a detailed assessment to identify thermal bridging and energy leaks. We fix high-performance insulation boards directly to your external masonry, which are then reinforced with a base coat and mesh. To finish, we apply a decorative, weather-resistant render such as K Rend or modern silicone systems. This process not only traps heat inside during winter but also provides a fresh, modern aesthetic that rejuvenates the exterior of your property while protecting the structure from damp and moisture ingress.

Why Should You Consider EWI for Your Property?

Many older homes in Monmouthshire suffer from solid wall construction that allows heat to escape rapidly. External wall insulation is the most effective way to address this, leading to lower monthly energy bills and a warmer, more stable indoor temperature throughout the year. Beyond immediate comfort, this upgrade is a proven method to improve your EPC rating. For landlords, this is a vital step towards meeting current MEES regulations, while homeowners benefit from a property that is both more comfortable to live in and more attractive to potential buyers.

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)

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.
