Expert Solid Wall Insulation Services in Llanwrtyd Wells

If you live in a period home or a stone-built cottage in Llanwrtyd Wells, you likely know the struggle of keeping your living space warm. Many older properties in Powys lack modern cavity walls, meaning heat escapes rapidly through the structure. At Global Plastering, we specialise in high-performance solid wall insulation, providing both External Wall Insulation (EWI) and Internal Wall Insulation (IWI). As PAS 2030 accredited professionals, we help homeowners across the region improve thermal comfort while significantly reducing their heating bills.

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.

How Solid Wall Insulation Transforms Your Home

For most homes in Llanwrtyd Wells, External Wall Insulation is the most effective solution. By applying a robust layer of insulation to the outside of your property and finishing it with a weather-resistant, breathable silicone render, we create a thermal shield that stops heat from leaking out. For listed buildings or properties where the exterior appearance must remain untouched, our Internal Wall Insulation provides a highly effective alternative. These measures do more than just lower your energy costs; they help eliminate cold spots, prevent mould caused by condensation, and significantly improve the overall EPC rating of your property.

Are You Living in a Hard-to-Treat Property?

Many properties throughout Powys, including traditional stone cottages, Victorian terraces, and non-traditional builds such as Airey or Wimpey no-fines houses, face unique thermal challenges. These structures are often energy-inefficient, making them expensive to run. Our team has the specific expertise required to assess these building types and deliver compliant retrofit solutions. Whether you are a private homeowner or a landlord needing to meet the latest MEES regulations for an HMO or rental, we provide professional guidance tailored to the structural needs of your home.

We provide SWIGA insurance-backed guarantees, offering you genuine peace of mind long after the work is complete.

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.
