Expert Solid Wall Insulation Services in Risca and Caerphilly

If you live in a property with solid walls in Risca or the wider Caerphilly area, you may have noticed that your home loses heat rapidly during the colder months. Unlike modern cavity walls, solid walls lack the insulating gap that keeps warmth inside, leading to cold draughts, rising energy bills, and potential issues with damp and mould. At Global Plastering, we specialise in advanced solid wall insulation solutions designed to transform the thermal efficiency of local homes. Whether you reside in a classic Victorian terrace or a non-traditional build, our team is here to help you create a warmer, more energy-efficient living space.

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.

Understanding Your Insulation Options EWI vs IWI

We offer two primary methods to combat heat loss. External Wall Insulation involves applying high-performance insulation boards to the outside of your property, which are then finished with a durable, weather-resistant silicone render. This approach is excellent for upgrading the aesthetic appearance of your home while ensuring minimal disruption to your interior space. Alternatively, Internal Wall Insulation is perfect for properties where the exterior character must be preserved or where space constraints prevent external work. Our internal dry-lining techniques focus on thermal bridging solutions, ensuring that your home remains comfortable throughout the year while also helping to improve your property’s overall EPC rating.

How Our PAS 2030 Accredited Process Works

As a PAS 2030 compliant company, we pride ourselves on delivering work that meets the highest industry standards for energy efficiency and retrofitting. The process begins with a comprehensive retrofit assessment to identify exactly where your property is losing heat and which materials will provide the most effective thermal barrier. Once we have a clear plan, our skilled technicians carry out the installation with precision, whether that involves installing high-spec rendering or specialised internal insulation boards. We manage every aspect of the project, ensuring that your home improvement is not only effective but fully compliant with modern building regulations.

Why Local Homeowners Trust Our Retrofit Expertise

Global Plastering brings extensive experience to every project in Risca, Caerphilly, and the surrounding regions. We understand the unique challenges faced by owners of varied building types, including traditional stone-built properties and more modern non-traditional structures such as Airey or Wimpey no-fines homes. By choosing us, you benefit from our commitment to quality, backed by our status as SWIGA-accredited installers. This means every eligible insulation project we complete comes with a 25-year insurance-backed guarantee, providing you with long-term peace of mind regarding the performance and durability of your home energy upgrade.

Supporting Landlords and Homeowners with EPC Compliance

Improving the energy efficiency of your property is a smart financial investment, whether you are a homeowner looking to lower monthly costs or a landlord aiming to meet MEES regulations. A higher EPC rating not only makes your property more attractive to tenants but also ensures your home is better protected against the long-term impacts of damp and condensation. Our team is fully equipped to guide you through the process of decarbonisation, helping you navigate the complexities of property retrofitting in South Wales. We are fully insured and registered, serving clients across a 35-mile radius of our base to ensure reliable, professional service whenever you need it.

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.
