Why Choose Us for Solid Wall Insulation?

Based in Ferndale and covering South Wales and South West England, Global Plastering is your trusted local partner for tackling cold, hard-to-heat homes. Whether you need External Wall Insulation (EWI) to transform a solid brick property or Internal Wall Insulation (IWI) to preserve a historic Victorian façade, our fully guaranteed retrofit services eliminate thermal bridging, lock in heat, and dramatically improve your EPC rating.

Why choose professional insulation for your property

Living in a home with solid walls often means dealing with cold surfaces and high heating costs. Unlike modern builds, these structures lack the cavity space needed for traditional filling, making specialised intervention essential. Our team addresses this through high-performance retrofitting that targets thermal bridging, effectively stopping heat from escaping through your walls. Whether you live in a traditional stone-built cottage or a non-traditional build like an Airey or Wimpey no-fines home, our solutions provide a robust barrier against the elements.

How do we improve your EPC rating and energy efficiency

Upgrading your property with our insulation systems is one of the most effective ways to improve your EPC rating. We follow strict PAS 2030 standards to ensure every project meets modern energy efficiency requirements. For landlords managing HMOs or private rentals in Y Coed Duon, our services are vital for meeting current MEES compliance regulations. By installing durable, weather-resistant finishes like silicone render on your exterior or precision dry-lining on your interior, we help create a property that is both warmer in the winter and more efficient year-round.

Our commitment to quality and industry-backed guarantees

Quality assurance is at the core of our operations. Global Plastering is a fully PAS 2030 accredited business and holds CHAS accreditation, ensuring that every installation is handled with professional care. As a SWIGA-accredited installer, we are proud to offer 25-year insurance-backed guarantees, providing you with long-term peace of mind for your home improvement investment. We are fully insured and operate as registered waste carriers, managing every stage of your retrofit project with strict attention to detail and regulatory compliance.

Frequently asked questions about solid wall insulation

Many homeowners ask whether their property is suitable for insulation. The answer depends on your specific construction, which is why we offer a comprehensive retrofit survey to assess your needs. Another common concern is the impact on aesthetics. Our modern silicone rendering systems are available in a wide range of colours and textures, ensuring that your home maintains its curb appeal while benefiting from improved thermal performance. If you are concerned about mould or damp, our insulation solutions are specifically designed to be breathable, helping to create a healthier, condensation-free living environment.

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 solid wall insulation, EWI solutions, and retrofit services in South Wales and South West England and across South Wales.

Does solid wall insulation cause damp?

+

When installed correctly by professionals like us, it actually helps prevent damp. By keeping the internal surface of the wall warmer, it stops water vapour in the air from condensing on the wall. We always make sure there is adequate ventilation as part of our PAS 2035 assessment to keep the air fresh and the walls dry.

Do I need planning permission for External Wall Insulation?

+

In many cases, EWI falls under "permitted development." However, if you live in a conservation area, a listed building, or if the insulation significantly changes the look of the front of your house, you might need permission. We can help advise you on the local rules in Rhondda Cynon Taf and beyond.

How long does the installation take?

+

For a standard semi-detached or terraced home, External Wall Insulation usually takes between 2 to 3 weeks, depending on the weather. Internal insulation can be faster but depends on how many rooms you are doing at once. We always aim to keep the workspace tidy and the disruption to a minimum.

Is it worth the investment?

+

Solid wall houses lose about twice as much heat as those with cavity walls. By insulating, you are making a long-term investment that protects the fabric of your building, slashes your carbon footprint, and saves you money every single month on your gas or electric bills.
