Black mould on internal wall in house caused by condensation and damp

Here’s what’s actually going on

Mould in your home usually comes down to two things:

1. Cold surfaces

External walls, corners, bay windows — these areas get cold.

2. Lack of proper ventilation

Moisture builds up from everyday living and has nowhere to go.

Warm air + moisture hits a cold wall

  • turns into water
  • then mould starts growing

Simple as that.

How we solve it

First, we identify exactly where the problem is — then we fix it by warming up cold wall surfaces, which is what stops condensation forming in the first place. In many cases, this can be done with a thin-coat cork insulation of around 3mm, adding no real thickness while helping to reduce moisture build-up and prevent mould from coming back. We also assess how ventilation is working and guide you on how to make it work properly alongside the upgrade.

Small change — big difference.

In many cases, this is resolved with proper internal upgrades such as Internal Wall Insulation or targeted solutions like Internal Cork Coating.
