Why Choose Our Condensation & Mould Prevention Services?

Why does mould return to my walls?

Black mould is often a symptom of cold surfaces meeting warm, moisture-laden air, creating condensation that settles on walls. In older properties, a lack of insulation and poor airflow are the main culprits. We assess your home to determine whether moisture is coming from rising damp, penetrating damp, or simple condensation. By installing high-performance internal wall insulation and advanced ventilation systems, we break this cycle. This approach not only removes the mould but stops it from returning, keeping your indoor air quality high and your living environment comfortable.

The Global Plastering Remediation Process

Our approach starts with a detailed retrofit survey to understand your building's unique requirements. We do not just mask the problem with paint; we address the underlying energy inefficiency. Our technicians install specialist ventilation systems to manage moisture and, where necessary, apply internal wall insulation to raise the temperature of the wall surface. Finally, we provide a high-quality plastering finish, leaving your walls smooth and ready for decoration. Every step is handled by our experienced, insured team, ensuring your property is restored to its best condition.

Improving Energy Efficiency and Compliance

Tackling damp and mould is a vital step toward improving your property's EPC rating and overall thermal efficiency. For landlords in Rhondda Cynon Taf, our services help you meet the Minimum Energy Efficiency Standards (MEES) required for rental compliance. By insulating solid walls and reducing heat loss, we help you lower energy bills while making your property more attractive to tenants or buyers. Our work is fully compliant with modern building regulations and supported by the quality assurance of SWIGA insurance-backed guarantees.

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.
