Understanding the Problem
Why Internal Walls Cause Condensation, Mould & Cold Spots
Cold internal walls are one of the most common causes of condensation and black spot mould in UK homes, especially in older and solid wall properties.
When a wall surface stays cold, moisture in the air naturally condenses on it. Over time, this creates the perfect conditions for mould to form. Dehumidifiers, mould sprays and anti mould paints may reduce symptoms, but they don’t address the underlying issue.
In many homes, external insulation isn’t possible due to planning restrictions, property type, or disruption. Traditional internal insulation boards can also make problems worse by trapping moisture behind the wall.
To permanently stop condensation and mould, the wall itself needs to be warmer, without sealing moisture in.
How We Fix Cold, Condensation-Prone Internal Walls
A simple, permanent approach that raises internal wall surface temperature and prevents condensation. Without trapping moisture or major disruption.
Thin Internal Insulation Layer
We apply a thin layer of natural cork that warms your walls and stops condensation at the source.
