Damp can cause mould on walls and furniture, and make wooden window frames rot.
Some damp is caused by condensation. But what causes condensation? What can you do about it?
There's always some moisture in the air, even if you can't see it. If the air gets colder, it can't hold all the moisture and tiny drops of water appear. This is condensation. You notice it when you see your breath on a cold day, or when the mirror mists over when you have a bath.
