Why Choose Global Plastering for Cavity Wall Insulation in Ferndale?

How our insulation process improves thermal comfort

Our insulation process begins with a detailed, professional survey to determine the suitability of your wall structure. We do not believe in one-size-fits-all solutions; we carefully assess your property to prevent issues like damp or interstitial condensation. Once confirmed, we inject high-performance insulating materials into the wall cavity, sealing those hidden gaps where heat escapes. This systematic approach effectively stops cold draughts and thermal bridging, creating a consistent internal climate that keeps your living spaces comfortable throughout the year.

Why upgrade your insulation to meet PAS 2035 standards?

Improving your home insulation is one of the most effective ways to increase your Energy Performance Certificate (EPC) rating. With rising utility bills and tightening landlord regulations, such as MEES compliance, our work helps you stay ahead of the curve. By following strict PAS 2035 retrofit standards, we ensure that your property is not just warmer, but also fully compliant with modern energy efficiency requirements. This is particularly vital for those looking to decarbonise their homes or prepare for future energy standards.

Frequently asked questions about cavity wall insulation

Many of our clients ask if cavity wall insulation is suitable for older properties. While some period homes feature solid walls, we can often advise on alternative solutions like internal or external wall insulation if a cavity is not present. Another common question relates to the installation time; most cavity treatments are completed in a single day with minimal disruption to your daily routine. Finally, all our work is backed by SWIGA insurance-backed guarantees, ensuring you have total peace of mind regarding the quality and durability of our workmanship. If you have questions about your specific wall type, please reach out to our team.

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.
