Why Choose Our External Wall Insulation Services Across South Wales?

How Our PAS 2030 Retrofit Process Works

We take a professional, evidence-based approach to every project. Our process begins with a detailed survey to assess your building type, whether it is a stone-built terrace or a non-traditional Cornish unit. As a PAS 2030 accredited company, we ensure that every stage of the installation adheres to strict PAS 2035 retrofit standards. This includes calculating the required insulation thickness, managing moisture control, and ensuring the finish is applied correctly to withstand the local climate.

Why Choose Our Professional EWI Services in Rhondda Cynon Taf

Upgrading to external wall insulation is one of the most effective ways to improve your property EPC rating. Beyond the immediate financial benefits of reduced energy usage, our systems provide a significant aesthetic uplift with high-quality silicone or monocouche rendering. We are SWIGA-accredited, meaning you receive an insurance-backed guarantee for your installation. This provides lasting peace of mind for homeowners and landlords managing MEES compliance requirements throughout Rhondda Cynon Taf.

Solving Cold House Issues and Improving Thermal Performance

If you notice cold spots on your interior walls or feel a persistent chill, your property is likely losing heat through its structure. Our solid wall treatment seals the building envelope, preventing heat from escaping and eliminating the damp conditions caused by cold surface temperatures. This is particularly effective for older, solid-wall properties that have never been insulated. By choosing Global Plastering, you are investing in a sustainable future for your home, protecting it against energy price fluctuations.

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.
