Why Choose Our Condensation & Mould Prevention Services?

Why does mould grow in my home?

Mould thrives in environments where moisture cannot escape. When warm, humid air hits a cold surface, such as a bridge in your wall or an uninsulated corner, it turns into water droplets. Over time, this condensation creates the perfect conditions for mould spores to grow. In many homes across Llantwit Major, this is caused by a lack of proper ventilation or thermal bridging where insulation is missing or ineffective. Addressing the balance between ventilation and insulation is the key to stopping the cycle of damp and mould growth for good.

Our approach to damp and humidity control

We follow strict PAS 2035 standards to ensure your home is treated correctly. Our process begins with a detailed survey to locate exactly where heat is escaping and where moisture is condensing. Depending on your property type, we may recommend installing modern, quiet-running mechanical ventilation systems and extractor fans to draw humidity out of bathrooms and kitchens before it spreads. For more severe cases, we provide advanced insulation solutions, such as internal or external wall insulation, which keep your wall surfaces warm and prevent the condensation from forming in the first place.

Meeting regulatory standards for landlords and homeowners

For landlords in the Vale of Glamorgan, ensuring your property meets Minimum Energy Efficiency Standards (MEES) and is free from mould is a legal and ethical requirement. We help property owners improve their EPC ratings through targeted retrofitting that not only eliminates mould risks but also boosts the overall thermal efficiency of the building. By choosing our PAS 2030 accredited services, you are investing in a healthier environment for your tenants and long-term protection for your property assets.

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 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.
