Why Choose Our Condensation & Mould Prevention Services?

Why Do My Walls Suffer From Damp and Mould?

Mould growth is rarely just a cosmetic issue; it is a symptom of an underlying thermal imbalance. In many older properties throughout Rhondda Cynon Taf, cold wall surfaces act as magnets for condensation, creating the perfect environment for spores to thrive. Our approach addresses this by installing internal wall insulation that raises the internal surface temperature, effectively neutralising the cold spots that cause moisture build-up. We also assess your current ventilation systems to ensure that excess humidity is safely extracted from kitchens and bathrooms before it can settle on your walls.

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.
