Why Choose Our Condensation & Mould Prevention Services?

Why does mould form in your property?

Mould is rarely just a surface issue. In many Gorseinon homes, moisture collects on cold surfaces where thermal bridging occurs. This is common in Victorian and traditional solid wall buildings where the wall temperature drops, causing condensation to form whenever warm, humid air touches the cold structure. By ignoring the cause, simple cleaning only offers a temporary fix. We focus on long-term damp proofing and moisture control that targets the physical reasons your home suffers from persistent condensation.

Our bespoke damp and ventilation solutions

We take a comprehensive approach to moisture management by combining insulation with intelligent ventilation. Our PAS 2030 accredited team frequently installs internal wall insulation to raise the surface temperature of your walls, preventing moisture from condensing. To ensure air quality, we integrate advanced PIV systems and high-performance ventilation solutions that replace stale, damp air with fresh, filtered air. This combination of measures is essential for reducing humidity levels and ensuring your home remains compliant with modern energy efficiency standards.

Professional standards for Swansea property owners

As PAS 2035 retrofit specialists, we provide solutions that are designed to stand the test of time. Whether you own a terraced house, a bungalow, or a commercial property, our team ensures every project meets rigorous quality standards. We offer SWIGA-backed guarantees for your peace of mind and maintain CHAS accreditation, giving our clients full confidence in the safety and longevity of our workmanship. For landlords in Swansea, our services are specifically tailored to help you meet MEES compliance and improve the overall EPC rating of your rental portfolio.

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."

"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 condensation prevention, mould control, and insulation services in South Wales and South West England.

Will adding insulation make my mould problem worse?

+

This is a common worry. If insulation is installed poorly without considering ventilation, it can cause issues. However, when done correctly by PAS 2030 accredited professionals like us, insulation is the cure for mould. By making the walls warmer, we prevent the moisture in the air from turning into liquid. We always assess your home’s ventilation as part of the process to ensure a healthy balance of fresh air and warmth.

Is there a difference between damp proofing and insulation?

+

Traditional damp proofing often focuses on "rising damp" from the ground. However, the vast majority of mould issues in South Wales are caused by "penetrating damp" or "condensation." Insulation addresses these by providing a thermal barrier and a waterproof outer layer (in the case of EWI). We don't just block the water; we change the temperature of the building to stop the damp from ever forming.

How long does it take to install internal wall insulation?

+

Every house is different, but for a standard terraced home in Ferndale, we can usually complete the insulation and plastering of the main external-facing walls within a few days. We work cleanly and efficiently to ensure your home is back to normal as quickly as possible, leaving you with warm walls and a smooth, paint-ready finish.

Does insulation help with my EPC rating?

+

Absolutely. Wall insulation is one of the most effective ways to jump up the EPC scales. This is vital for homeowners looking to sell and essential for landlords who must meet MEES compliance. A better EPC rating usually means a higher property value and much lower monthly outgoings for heating.

What is thermal bridging and why does it matter?

+

Thermal bridging happens when a specific part of a wall is much colder than the rest—like a concrete lintel over a window or the corner of a room. These "bridges" allow heat to escape and are usually the first places mould will grow. Our insulation systems are designed to cover these bridges, creating a continuous thermal envelope around your living space.
