Why Choose Global Plastering for Cavity Wall Insulation in Ferndale?

Why choose cavity wall insulation for your home?

Many properties in the Vale of Glamorgan were built with a cavity between the inner and outer walls. Without proper insulation, this empty space allows heat to escape, making your home difficult to warm and expensive to heat. Our cavity wall insulation creates a seamless thermal barrier, helping to retain warmth during the winter and keeping your home cooler in the summer. By improving your insulation, you can effectively lower your annual heating costs and improve your property's overall EPC rating.

Our professional installation process for Vale of Glamorgan residents

We begin every project with a thorough assessment of your home, whether you live in a detached house, a semi-detached property, or a modern apartment. Our team evaluates your walls to ensure they are suitable for insulation and compliant with PAS 2035 retrofit standards. Once confirmed, we inject high-grade insulating materials into the cavity through small, discreet holes in the external brickwork. These are carefully filled and matched afterwards, ensuring the aesthetic of your property remains undisturbed.

Meeting high standards with SWIGA and PAS 2030

Quality and peace of mind are at the heart of our service. As a CHAS accredited and PAS 2030 compliant company, we strictly adhere to rigorous industry regulations. We are proud to provide a 25-year SWIGA guarantee on our cavity wall insulation projects, offering you long-term protection for your investment. Whether you are a private homeowner or a landlord seeking MEES compliance, our retrofit expertise ensures your property is fully protected.

Frequently asked questions about insulation in Cowbridge

How do I know if my walls are suitable for insulation? Our team conducts a pre-installation survey to check for wall condition, exposure to wind-driven rain, and other structural factors. Is the work messy? We take great care to ensure our process is clean, tidy, and minimal in disruption. Can this help with ECO4 grants? As retrofit experts, we can advise on how our insulation services align with energy-saving grant criteria.

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.
