Why Choose Our External Wall Insulation Services Across South Wales?

How Our EWI Systems Enhance Your Property

External wall insulation, or EWI, involves applying a layer of high-performance thermal insulation to the exterior of your property, followed by a durable, weather-resistant render finish. This process creates a thermal envelope that prevents heat from escaping through your walls. It is a highly effective solution for various building types found in Ferndale, including traditional Victorian terraces, semi-detached homes, and non-traditional builds like Cornish units or Wimpey no-fines constructions. By treating the exterior, we eliminate cold spots and thermal bridging, effectively upgrading your property energy efficiency and improving your EPC rating in one go.

Why Choose Global Plastering for Your Retrofit?

Choosing the right contractor is essential when dealing with energy efficiency upgrades. As a fully PAS 2030 accredited company, we adhere to the highest industry standards for every installation. We offer SWIGA-backed insurance guarantees, providing you with long-term peace of mind regarding the quality and durability of our work. Whether you are a private homeowner looking to reduce fuel poverty or a landlord needing to meet the latest MEES compliance standards for your HMOs, our team delivers professional, compliant, and cost-effective insulation projects that add lasting value to your building.

Is External Wall Insulation Right for My Home?

Many homeowners in Ferndale ask if EWI is suitable for their specific property. The answer depends on your wall structure and existing condition, which is why we always begin with a thorough, professional survey. EWI is perfect for solid-wall houses that lack a cavity, as it provides a superior thermal barrier without reducing your internal living space. We handle all aspects of the process, including advice on planning permissions for conservation areas or properties where the aesthetic finish is a priority. From classic rendered looks to brick-slip finishes, we ensure your home 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!"

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.
