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 Your Property Needs Thermal Protection

Solid masonry walls are notorious for acting as a bridge for heat to escape, leading to cold internal surfaces, condensation, and potentially even mould growth. By installing external wall insulation or internal wall insulation, you create a protective thermal blanket that keeps heat inside during the colder months. Beyond the immediate comfort, these upgrades significantly improve your property's EPC rating, which is essential for meeting modern decarbonisation standards and enhancing the overall value of your home in the local Brynmawr property market.

Our Approach to PAS 2030 Standards and Compliance

As a PAS 2030 accredited company, we manage every installation with precision and technical rigour. We understand the unique challenges faced by homeowners in Blaenau Gwent, including the specific requirements for heritage properties or homes within conservation areas. Our retrofit assessments ensure that the insulation solution chosen is compatible with the structure of your wall, preventing issues like interstitial condensation. By choosing us, you are guaranteed a process that prioritises safety, legal compliance, and long-term energy performance.

Do You Need External or Internal Insulation Solutions?

The choice between External Wall Insulation (EWI) and Internal Wall Insulation (IWI) depends on your property layout and planning permissions. EWI involves adding an insulated layer to the exterior, often finished with high-quality silicone rendering to provide a fresh, weather-resistant facade. IWI is the preferred choice for properties where exterior features must be preserved or where space outside is limited. Our team will guide you through the pros and cons of both methods to ensure you receive the most effective thermal upgrade for your specific building type.

Quality Assurance and Protecting Your Investment

We take pride in our work and stand by the quality of our installations. As a SWIGA-accredited installer, we offer insurance-backed guarantees, giving you peace of mind that your investment is protected. We are also well-versed in helping clients navigate potential energy-saving grants that may be available for eligible properties in the area. For landlords in Brynmawr looking to meet MEES compliance, we provide the documentation and high-quality workmanship needed to satisfy regulatory requirements.

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.
