As fully PAS 2030 accredited, CHAS registered, and SWIGA-backed experts, we guarantee our PAS 2035 compliant retrofit services will dramatically improve your EPC rating and safeguard your home against high energy bills. What’s more, by partnering seamlessly with our sister company, Global Plastering, we provide a complete end-to-end service—from advanced damp proofing and insulation to a flawless traditional plaster finish.

Why Do Cold Walls Cause Damp and Mould?

Condensation occurs when warm, moisture-laden air hits cold internal surfaces, such as uninsulated solid walls. In many older properties throughout South Wales, this temperature difference leads to moisture build-up, which eventually encourages black mould growth and damages your home interior. Our approach focuses on removing the cold spots that trigger these issues. By installing advanced insulation systems, we stabilise your internal wall temperatures, ensuring that moisture cannot settle. This isn't just about covering up a problem; it is about providing a permanent thermal solution that protects your property structure and your family health.

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited damp, black mould, and condensation control solutions in South Wales and South West England and throughout South Wales.

Will insulating my walls definitely stop the black mould?

+

Yes, in the vast majority of cases. Black mould is usually caused by condensation forming on cold spots. By installing External or Internal Wall Insulation, we raise the surface temperature of your internal walls. When the walls are warm, the moisture in the air stays in the air (to be cleared by ventilation) rather than turning into water on your wallpaper.

What is thermal bridging and why is it making my house damp?

+

Thermal bridging happens when a more conductive material (like a solid brick or a concrete lintel) allows heat to bypass your insulation. This creates a "cold bridge." These spots are where you will usually see mould first. Our PAS 2035 assessments identify these bridges so we can "break" them with proper insulation.

Do you offer guarantees on damp proofing and insulation?

+

Absolutely. Because we are SWIGA accredited, our external wall insulation comes with a 25-year insurance-backed guarantee. This gives you long-term security that your home will stay dry and warm for decades to come.
