Why Choose Our External Wall Insulation Services Across South Wales?

Why choose external wall insulation for your home

Many properties in the Caerphilly region, particularly older Victorian terraces and non-traditional homes like Airey or Cornish units, suffer from poor thermal performance. By applying external wall insulation, we effectively wrap your property in a protective layer that keeps warmth inside during the winter and prevents overheating in the summer. This process eliminates cold spots and draughts, creating a consistent temperature throughout your home. Beyond the comfort benefits, our installations significantly boost your home’s energy efficiency, often leading to a higher EPC rating which is essential for modern property standards.

Our professional installation process and standards

Quality and compliance are at the heart of everything we do at Global Plastering. We are fully PAS 2030 accredited and CHAS registered, ensuring that every project adheres to strict PAS 2035 retrofit standards. Our team conducts a thorough assessment of your building type to ensure the correct specification of insulation materials is used. Following the insulation installation, we apply high-quality, breathable finishes such as silicone rendering or K Rend, which not only protect your walls from the elements but also provide an aesthetic facelift to your property. Every installation we complete is backed by SWIGA insurance-backed guarantees, giving you complete peace of mind.

Serving Rhisga and the surrounding Caerphilly area

We operate within a 35-mile radius of the Rhisga and Risca area, providing dedicated support to clients across Caerphilly and the neighbouring districts. Whether you own a terraced house, a bungalow, or a commercial office building, our expert team is equipped to handle the unique challenges of your structure. We understand the local housing stock and the specific requirements for upgrading energy efficiency in the region, ensuring your project is handled by professionals who know the area inside out.

Common questions about our insulation services

Many of our clients ask if external wall insulation requires planning permission. While some minor alterations may fall under permitted development, we always advise on your specific situation, especially for homes in conservation areas. Another frequent question relates to the impact on the property look; with our range of silicone and K Rend finishes, we can mimic traditional appearances or create a modern aesthetic. For landlords concerned about MEES compliance, our energy-efficient upgrades provide a clear solution for meeting current 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.
