Questions about condensation and mould ventilation fixes in Greater Manchester

Can you tell if it is rising damp?

We can tell you when the pattern does not look like condensation, such as a tide mark low on a wall or damp that appears after rain, and point you to the right specialist.

What is the main cause of condensation in a house?

The main cause is moisture from everyday living, such as showers, cooking and drying clothes, that is not being extracted, combined with cold surfaces where it condenses. Poor or failed extract fans are a very common cause.
