Why Choose Our External Wall Insulation Services Across South Wales?

Why Choose External Wall Insulation for Your Property

Many properties in Pontypridd, particularly older Victorian terraces and traditional solid-wall homes, suffer from significant heat loss through their masonry. External wall insulation acts as a thermal blanket, wrapping your home in high-performance materials that stop heat from escaping and cold from penetrating the structure. By upgrading your insulation, you effectively address damp issues and cold spots while significantly improving the EPC rating of your building. This investment not only enhances your daily living comfort but also contributes to the long-term value and sustainability of your property.

How Does the Installation Process Work

Our process begins with a comprehensive retrofit survey to assess your property's specific requirements, whether you own a standard brick home, a concrete structure, or a non-traditional build like an Airey or Wimpey no-fines house. We apply the insulation boards directly to the outer walls, which are then finished with a high-quality, weather-resistant render system. This process is managed by our PAS 2030 accredited experts, ensuring full compliance with current building regulations. From the initial consultation to the final finishing coat, we manage every aspect of the project with minimal disruption to your home life.

Expertise in Local Compliance and Retrofit Standards

Navigating energy efficiency legislation can be complex, especially for landlords or homeowners aiming to meet MEES and EPC targets. As a specialist in Rhondda Cynon Taf retrofitting, Global Plastering provides guidance on PAS 2035 standards and necessary planning permissions for conservation areas. We take pride in our status as a SWIGA-accredited installer, meaning your project is backed by insurance-backed guarantees.

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.
