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 Solid Wall Insulation Is Essential for Your Property

Solid walls are notorious for letting heat escape, which often results in cold draughts, damp patches, and uncomfortably low room temperatures during the colder months. Our insulation systems act as a thermal blanket, significantly reducing the demand on your heating system and lowering your monthly fuel bills. Beyond simple comfort, our insulation work helps improve your property's EPC rating, which is increasingly vital for homeowners and landlords looking to meet modern decarbonisation standards. Whether you live in a detached family home or a Victorian terrace, our solutions effectively eliminate thermal bridging and cold spots.

Our Approach to PAS 2035 Compliant Retrofitting

We take a rigorous, professional approach to every retrofit project in Monmouthshire. As fully PAS 2030 compliant contractors, we adhere to the latest PAS 2035 standards to ensure your insulation is installed to the highest possible technical specification. Our process begins with a detailed retrofit assessment to understand your property's unique ventilation and moisture requirements. This careful planning ensures that our EWI or IWI installations provide lasting protection against damp and mould while significantly enhancing the thermal efficiency of your building fabric.

Can Solid Wall Insulation Solve Your High Energy Bills?

If you are struggling with rising energy costs, addressing uninsulated solid walls is one of the most effective steps you can take. Many residents in Cil-Y-Coed and Caldicot find that their heating feels ineffective because heat is rapidly lost through the structure of the building. By installing our high-quality insulation, you can retain that heat much longer, creating a comfortable indoor climate year-round. This is particularly beneficial for those in hard-to-heat property types, including concrete units and solid stone cottages, where traditional methods often fail to deliver the same impact.

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.
