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 solid walls

Many properties in Llandeilo were built with solid walls rather than modern cavity structures, meaning they lose heat rapidly through the masonry. This lack of thermal mass often leads to cold walls, condensation, and mould growth. By choosing our insulation systems, you create a durable, weather-resistant barrier that protects the building structure while keeping your living areas warm. Whether you occupy a terraced home, a detached bungalow, or a commercial premise, our retrofitting services directly improve your EPC rating and overall thermal comfort.

The importance of PAS 2035 compliance in Carmarthenshire

Retrofitting a home involves more than just applying insulation; it requires a deep understanding of how a building breathes. As fully PAS 2030 accredited and CHAS registered contractors, we ensure every installation adheres to strict PAS 2035 standards. This rigorous approach considers essential ventilation requirements and moisture control, protecting the long-term integrity of your home. We handle the complexities of the process, including guidance on planning permissions for conservation areas, so you can enjoy a more efficient property without the regulatory headache.

Common questions regarding solid wall insulation

Will insulation change the look of my period property? We offer various finishes that can replicate traditional textures or provide a modern, sleek aesthetic suitable for both historic and contemporary homes. How does insulation impact energy bills? By wrapping your home in a thermal layer, you can expect a significant reduction in heat loss, which helps protect against rising energy prices. Do you offer guarantees for the work? Yes, we provide SWIGA insurance-backed guarantees, ensuring that your investment is fully protected for years to come. Our team is always on hand to discuss how these systems work in the context of your specific building type.

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.
