Damp can cause mould on walls and furniture, and make wooden window frames rot
Some damp is caused by condensation. 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. You notice it when you see your breath on a cold day, or when the mirror mists over when you have a bath.
Condensation is mostly a problem in cold weather – whether it’s raining or dry. It appears on cold surfaces and in places where there is little air movement – in corners, on or near windows, in or behind wardrobes and cupboards.
Condensation isn’t the only cause of damp. It can also come from:
- Leaking pipes, waste and overflows – see how to prevent burst and leaks in cold weather
- Rain penetrating gaps in the brickwork, roof, window frames, and around doors
- Rising damp due to a faulty damp proof course
