Why Choose Our Condensation & Mould Prevention Services?

Why Do Cold Walls Cause Mould Growth?

Mould often thrives in properties suffering from thermal bridging, particularly in older Victorian, solid wall, or non-traditional construction homes common throughout Blaenau Gwent. When warm, moist air meets cold surfaces, it condenses into water droplets, creating the ideal conditions for black mould to take hold. Our team tackles this by addressing the heat loss points in your property, using professional-grade insulation and ventilation strategies that stop the cold from creeping in through your walls.

PAS 2035 Compliant Retrofit Solutions

As PAS 2030 accredited specialists, we pride ourselves on delivering work that meets the highest industry benchmarks, including PAS 2035 retrofit standards. We don't believe in quick fixes that fail after a few months; instead, we implement comprehensive energy-efficiency measures. Whether through targeted internal wall insulation or external wall insulation systems, our installations reduce the temperature differential on your walls, effectively eliminating the surface moisture that leads to mould development.

Supporting Landlords with MEES and EPC Compliance

For property owners and landlords in Nantyglo, managing damp and mould is not just about tenant health, it is a regulatory requirement. Under Minimum Energy Efficiency Standards (MEES), ensuring your property is correctly insulated and ventilated is essential for maintaining a valid EPC rating. We help landlords improve their properties' thermal efficiency and ensure they remain compliant, protecting both your investment and your reputation as a responsible provider.

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.
