Condensation & Mould Treatment

Condensation is the most common cause of damp in UK homes — and the most frequently misdiagnosed. We identify the true cause and provide lasting ventilation solutions.

What Is It?

Understanding Condensation & Mould

Condensation occurs when warm, moisture-laden air meets a cold surface and the water vapour turns to liquid. In homes, this is most common on windows, external walls, and in poorly ventilated areas such as bathrooms, kitchens, and bedrooms. Left untreated, it leads to black mould growth which can affect health and damage the property.

Our Approach

How We Treat Condensation & Mould

Our surveyors carry out a full assessment to confirm condensation as the cause and rule out rising or penetrating damp. We then specify the most appropriate ventilation solution — this may include a Positive Input Ventilation (PIV) unit, localised extraction fans, or a combination of both. We also treat existing mould growth with specialist biocidal wash and, where necessary, apply anti-mould paint systems.
