Brittany Road Project Condensation & Damp Issues

Brittany Road Project

This property suffered from extensive mold growth due to severe condensation, primarily affecting the cold internal surfaces of exterior walls. Upon inspection, we identified a lack of ventilation as the primary cause. When internal walls are cold and the property is heated, condensation forms, particularly during colder months. Without adequate ventilation, this moisture becomes trapped, leading to damp conditions and surface mold growth.

In addition to the ventilation issue, we discovered that the kitchen lacked proper extraction. The cooker’s location prevented moisture from being effectively removed, allowing steam and condensation to spread throughout the property rather than being extracted as intended.

Our Solution

To address these issues, we implemented our ISO Therm Guarantee-Backed System on all affected walls. This advanced system not only prevents condensation buildup but also improves thermal efficiency, increasing wall temperatures by over 7 degrees. This significantly reduces the risk of condensation and subsequent mold growth.

In addition to the ISO Therm system, we installed extractor fans and trickle vents on the windows to ensure proper air circulation. These measures allow any residual moisture to escape, preventing future damp-related issues.

The Process

1. Preparation – We began by thoroughly cleaning the walls, removing all mold, and stripping back any damaged render, plaster, and paint. Any compromised areas were repaired using our damp-proof rendering mix to create a smooth, stable surface for application.

2. ISO Therm System Application – ISO Therm is a high-performance internal wall insulation and damp control system, ideal for projects like this. Unlike traditional damp-proof rendering, which is more labor-intensive, costly, and disruptive, ISO Therm provides a seamless solution. We applied the system using a specialized adhesive similar to tile adhesive, bonding the ISO Therm material directly to the walls. This unique, patented polyester-based material is flexible, lightweight, and offers superior insulation, effectively eliminating condensation-related issues.

3. Finishing Touches – Once the ISO Therm system was installed, we reinforced all joints with scrim tape, similar to plasterboard finishing techniques. We then applied a full plaster coat over the system, ensuring a smooth and durable finish.

4. Final Enhancements – After the plaster had fully dried, we completed the project with a fresh coat of paint, new carpets, and upgraded radiators, giving the property a modern and refreshed appearance. These finishing touches were particularly important as the client intended to sell the property following the completion of the works.
