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 do solid wall properties lose heat so quickly?

Solid wall properties act like a thermal bridge, drawing heat out of your living space and allowing cold, damp air to penetrate. This is a common issue for homeowners in Treherbert, where traditional building techniques did not account for modern energy efficiency standards. Without proper retrofitting, you may find your walls feel perpetually cold, leading to condensation and mould growth. We specialise in identifying these thermal weaknesses and applying high-performance insulation to create a comfortable, dry, and energy-efficient environment for your family.

Expert insulation solutions for diverse property types

Whether you live in a charming semi-detached cottage, a stone-built terraced house, or a non-traditional build like an Airey or Cornish unit, we have the technical expertise to help. Our team is fully trained in modern retrofitting techniques that respect the architectural character of your home while ensuring compliance with rigorous PAS 2035 standards. We manage the entire process from initial assessment to final finish, ensuring that your property not only meets the latest energy efficiency requirements but also looks fantastic.

Commitment to quality through SWIGA and PAS standards

We pride ourselves on our reputation as a trusted, PAS 2030 accredited installer. Our work is backed by SWIGA, offering you peace of mind with insurance-backed guarantees on every installation. This commitment to quality ensures that our insulation projects contribute directly to local decarbonisation efforts while providing you with long-term protection against rising fuel costs. We work closely with homeowners and landlords to ensure all properties, including HMOs, meet the necessary MEES compliance for improved energy performance.

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.
