Why Choose Global Plastering for Cavity Wall Insulation in Ferndale?

How our insulation process works for your property

Our process begins with a detailed thermal assessment of your building. We examine the current state of your walls to identify heat loss and check for potential issues like damp or structural integrity. Whether you live in a traditional terraced house or a more modern detached property, we use precision techniques to fill the cavity space with high-performance insulation material. This creates a thermal barrier that prevents warmth from escaping, significantly reducing the energy required to heat your home throughout the winter.

Why choose our PAS 2035 compliant solutions

We pride ourselves on adhering to strict PAS 2035 retrofit standards, which is essential for modern energy efficiency projects. By choosing a professional team, you ensure your property is treated with the correct materials suited to its specific construction, whether it is a standard build or a non-traditional structure. Our work helps you improve your EPC rating and assists landlords in meeting the latest MEES compliance regulations. We bring expertise and technical precision to every project across Pontllanfraith and the surrounding 35-mile radius.

The benefits of upgrading your insulation

Installing cavity wall insulation is one of the most effective ways to lower your energy bills and eliminate cold spots in your home. By reducing thermal bridging, we help you create a consistent, comfortable temperature in every room. Beyond the financial savings, our installations contribute to a more sustainable building, aiding in local decarbonisation efforts. For peace of mind, all our insulation work is backed by a 25-year insurance-backed guarantee through SWIGA, providing long-term security for your investment.

Common questions about cavity wall insulation

Many customers ask whether their property is suitable for insulation. We regularly work with diverse building types, from Victorian properties to Wimpey no-fines and Airey homes, conducting thorough checks to ensure suitability. Another frequent concern is the disruption caused during the installation; our team is trained to work efficiently, ensuring the process is as non-invasive as possible. If you are worried about existing damp, our surveys are designed to identify and address these risks before any material is installed, ensuring your home remains healthy and breathable.

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.
