Why Choose Our Condensation & Mould Prevention Services?

Understanding the Causes of Damp in Vale of Glamorgan Homes

Condensation typically occurs when warm, moist air meets cold surfaces, such as solid walls or single-glazed windows. In the maritime climate of Barry, many older properties struggle with thermal bridging, where heat escapes through structural elements and creates cold spots perfect for mould growth. Our experts analyse your property to determine whether the issue stems from inadequate airflow, insufficient insulation, or rising damp. By addressing these factors, we prevent the cycle of moisture that damages your internal finishes and impacts your wellbeing.

Professional Solutions for a Healthier Living Environment

We offer a range of targeted interventions, including the installation of high-performance mechanical ventilation systems and humidity-controlled extractor fans. For properties suffering from significant heat loss, we provide advanced internal and external wall insulation solutions that meet PAS 2035 standards. This approach not only improves energy efficiency but also keeps walls warmer, effectively eliminating the surface temperatures that lead to condensation. Our retrofit services are designed to be minimally invasive while providing maximum protection against moisture ingress.

Compliance and Retrofit Standards for Local Property Owners

As a PAS 2030 accredited business, we ensure all our work adheres to rigorous industry standards. For landlords across the Vale of Glamorgan, maintaining MEES compliance is essential for both legal requirements and tenant satisfaction. We help you navigate the complexities of property upgrades, ensuring that all insulation and ventilation work enhances your building's EPC rating. Whether you own a bungalow, a terrace, or a commercial office space, our technical expertise ensures that your damp-proofing measures are both effective and compliant.

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.
