Why Choose Our External Wall Insulation Services Across South Wales?

Solving Heat Loss and Improving EPC Ratings

Many older homes in the Caerphilly region suffer from significant heat loss due to uninsulated solid walls. This leads to cold spots, draughts, and the potential for damp or mould growth. Our professional insulation systems address these issues directly, often resulting in a substantial improvement to your property's EPC rating. For landlords, this is an essential step toward meeting modern MEES compliance standards. By choosing our insulation solutions, you are not just making a aesthetic change; you are investing in a healthier, more cost-effective property that is future-proofed against rising energy costs.

Is your property suitable for EWI and rendering?

We have extensive experience working with a wide range of building types found throughout Abercarn and South Wales. This includes solid wall construction, concrete homes, and various non-traditional builds such as Airey or Cornish units. We understand the unique thermal bridging challenges these properties present. Our process begins with a detailed assessment to ensure the installation is compatible with your specific wall construction. From the initial survey through to the final decorative silicone or K Rend finish, we maintain strict adherence to PAS 2035 retrofit standards to ensure your home receives the highest quality care.

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.
