There are many different types of damp and mould. These are the most common.  


Condensation happens when your home is too humid and the warm air hits cold surfaces making it cool quickly.

Rising damp 

This is when moisture from the ground travels up through the walls.

Penetrating damp

This is when water is getting into the home through an external wall. This may be because of damaged bricks, windows or tiles, blocked gutters or leaks.
