Expert Solid Wall Insulation Services in Rhymni and Rhymney

Global Plastering is your dedicated local specialist for solid wall insulation in Rhymni and Rhymney. We help homeowners across Caerphilly transform cold, inefficient properties into warm, energy-efficient homes. Many homes in our area, particularly classic Victorian and Edwardian builds, feature solid walls that lack the thermal protection of modern cavity construction. This often leads to significant heat loss, damp issues, and rising energy bills. Our professional team provides expert solutions to bridge this gap, ensuring your property is prepared for the elements while significantly lowering your monthly heating costs.

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 Home Needs Professional Thermal Upgrades

Solid walls are notorious for acting like a heat sink, absorbing cold from the outside and transferring it directly into your living spaces. By installing external wall insulation or internal wall insulation, you create a thermal blanket that prevents heat loss and eliminates cold bridging. Our retrofitting services are designed to improve your home's EPC rating, making it a warmer, more comfortable environment during the winter and a cooler space throughout the summer. Whether you live in a traditional terraced house or a non-traditional build like an Airey or Wimpey no-fines home, we provide the expertise needed to solve your insulation challenges permanently.

How Does Our Insulation Process Work?

We follow a rigorous, PAS 2030 accredited process to ensure every project meets the highest industry standards. For external wall insulation, we apply high-performance insulation boards followed by a durable, breathable silicone render, which provides an attractive, weather-resistant finish. If external work is not suitable, we offer internal wall insulation using precision dry-lining techniques to minimise space loss while maximising thermal performance. Our team handles every aspect of the retrofit, from the initial survey and design to the final installation, ensuring full compliance with current building regulations.

Quality Assurance and Regulatory Compliance

As a CHAS and PAS 2030 accredited company, we pride ourselves on technical excellence and safety. We understand the specific requirements for upgrading older housing stock in Rhymni and the wider Caerphilly area. For added security, we provide insurance-backed guarantees through SWIGA, offering you complete peace of mind for the next 25 years. We also support landlords with meeting mandatory MEES requirements, ensuring your rental properties remain compliant and attractive to future tenants through improved energy efficiency and reduced mould risks.

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.
