What causes condensation and mould?
Everyday activities such as cooking, washing and bathing can cause condensation.
This is where moisture in the air makes contact with a cold surface, such as a window and condenses leaving water droplets on the cold surface.
If this happens on a regular basis, a fungus called 'black mould' can form on walls, ceilings, clothes and furniture.
As well as affecting plasterwork and rotting window frames, black mould can affect your health if not treated.
