Understanding the Difference

Damp and condensation are often confused, but identifying the correct cause is essential to fixing the problem effectively — and avoiding wasted money on the wrong remedy.

Condensation is by far the most common cause of damp-related complaints in UK homes.

Signs of Condensation

Condensation typically appears on cold surfaces and in poorly ventilated areas.

• Water droplets on windows and cold walls
• Black spot mould in corners and around windows
• Musty smells, especially in bedrooms and bathrooms
• Worse in winter and in rooms with poor airflow

Signs of Penetrating or Rising Damp

Genuine damp comes from water entering the structure of the building.

Rising damp is far less common than often claimed, and is characterised by a tide mark low down on walls.

How to Address Each Problem

Condensation is usually managed by improving ventilation, heating and insulation. Damp requires identifying and stopping the source of water ingress. An independent timber and damp survey will accurately diagnose which you are dealing with.
