Why Choose Our External Wall Insulation Services Across South Wales?

Why choose external wall insulation for your Gorseinon property?

Many older properties in South Wales suffer from significant heat loss through uninsulated walls. By installing a high-performance external wall insulation system, you create a thermal envelope that keeps heat inside during winter and maintains a cooler temperature during summer. This process not only tackles fuel poverty but also helps improve your property's EPC rating. As we move towards stricter decarbonisation goals, our work helps your home meet modern energy standards while protecting the structure from damp and thermal bridging.

Our professional installation and rendering process

Our process begins with a thorough retrofit assessment to ensure the system is perfectly suited to your building type. We apply high-performance insulation boards directly to your external walls, which are then reinforced and finished with premium silicone or monocouche render. These finishes provide a durable, weather-resistant, and aesthetically pleasing facelift to your home. We manage every stage of the project with precision, ensuring that the installation adheres strictly to PAS 2030 retrofit standards for your safety and long-term comfort.

Meeting local retrofit standards with peace of mind

We take pride in our status as a PAS 2030 accredited installer, which means we work to the highest industry benchmarks for energy efficiency and quality. For every project in Gorseinon and the surrounding 35-mile radius, we provide SWIGA insurance-backed guarantees. This gives you complete peace of mind that your investment is protected and that the work will stand the test of time, regardless of whether you are upgrading a single home or managing a larger commercial portfolio.

Common questions about solid wall insulation

Will external wall insulation change the look of my home? Yes, it often enhances it by providing a fresh, clean finish with high-quality render, though we always consider planning requirements for conservation areas. Can this work improve my EPC rating? Absolutely, upgrading your insulation is one of the most effective ways to move your energy rating up a band or two. Do you offer services for commercial buildings? Yes, we support both domestic and commercial decarbonisation projects, including offices and HMOs, helping landlords meet current MEES compliance regulations.

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.
