Why Choose Our External Wall Insulation Services Across South Wales?

Why Solid Wall Properties in Carmarthenshire Need EWI

Many properties in the Llandovery area, including classic Victorian terraces, detached bungalows, and various non-traditional builds like Wimpey no-fines houses, were constructed without adequate insulation. These solid wall structures often act as a bridge for cold, leading to significant heat loss and damp issues. External Wall Insulation acts as a protective thermal blanket around your home. By applying this system, we stop cold spots from forming and prevent the cycle of rising heating costs that many local residents experience during the winter months.

Our Comprehensive Approach to Retrofit Compliance

We take a professional, end-to-end approach to your home improvement project. Following PAS 2035 retrofit standards, our team ensures every detail is calculated to maximise performance and longevity. From initial retrofit assessment to the final decorative finish, we guide you through the process, including assistance with ECO4 funding applications where eligibility allows. Because we are SWIGA-accredited, every project comes with the peace of mind of an insurance-backed guarantee, proving our commitment to quality across all our work in Carmarthenshire.

Transforming Aesthetics with High-Performance Rendering

Beyond the thermal benefits, our EWI systems allow for a complete aesthetic transformation of your exterior. We offer a range of modern finishes, including premium silicone rendering, which is breathable, flexible, and crack-resistant. This creates a low-maintenance, weather-proof facade that elevates the kerb appeal of your property while protecting the structural integrity of your walls. Whether you are looking to refresh a tired Victorian exterior or update a commercial building, our finish ensures your property looks as good as it performs.

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.
