Why Choose Global Plastering for Cavity Wall Insulation in Ferndale?

How Our Cavity Wall Insulation Process Works

We begin every project with a thorough technical survey to assess the condition of your walls and determine suitability. Our experienced team uses advanced inspection techniques to identify existing voids or potential issues such as damp, which must be addressed prior to any insulation installation. Following the assessment, we use high-grade materials to fill the cavities, creating a continuous thermal barrier that effectively reduces heat transfer. The process is clean, efficient, and performed by our skilled technicians who are trained to handle various building types, from traditional terraces to modern detached homes across Powys.

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!"

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited cavity wall insulation, heat loss reduction, and energy efficiency services in South Wales and South West England.

Why Choose Global Plastering for Your Retrofit Project?

+

Choosing the right installer is just as important as the insulation itself. Poorly installed cavity fill can lead to damp issues and cold bridging, which is why we prioritise quality above everything else.
We are fully PAS 2030 compliant, which is the industry gold standard for energy efficiency installers. This accreditation means our work is regularly audited to make sure it meets the highest possible technical levels. Furthermore, we provide SWIGA (Solid Wall Insulation Guarantee Agency) or equivalent insurance-backed guarantees. This gives you total peace of mind that your investment is protected for years to come.
As a CHAS-accredited company and a licensed waste carrier, we maintain a safe, clean, and professional site from start to finish. Our team handles the project with the expertise that comes from years of experience in plastering, rendering, and energy-saving measures.

How do I know if my house has cavity walls?

+

A quick way to tell is by looking at your brickwork. If the bricks are all the same length and laid in a regular pattern, you likely have a cavity wall. If you see a mix of long and short brick ends (a "header" pattern), the wall is likely solid. We can confirm this for you during a quick site survey.

Will cavity wall insulation cause damp?

+

When installed correctly by a PAS 2030 accredited professional, insulation actually helps prevent damp by reducing condensation. We always check your property for existing issues or debris in the cavity before we start to make sure the installation is safe for your home.

How long does the installation take?

+

For a standard semi-detached house, the job is usually finished in less than half a day. There is no need for you to leave the house, and we don't need to come inside for the majority of the process.

Is it worth doing if I’m planning to sell my house?

+

Absolutely. An energy-efficient home with a higher EPC rating is much more attractive to buyers. It shows that the property has been well-maintained and will be cheaper for the new owners to run.
