Condensation is by far the most common cause of dampness in buildings and affects both old and new buildings. It usually leaves a musty smell and mould growth or spores.
A lot of moisture is produced in the air whenever you cook, run a bath/shower or dry clothes in your home. When this moisture meets a cold surface it turns into droplets of water called condensation and, if left, will develop into mould.
This usually happens on cold, outside surfaces and walls and in areas where the air does not flow well. It can damage clothes and furnishings. You can reduce the problem by:
- Wiping moisture away whenever you see it
- Keeping a window open if you need to dry clothes indoors
- Only using a tumble dryer with good airflow
- Keeping all the rooms in your property warm – even by keeping your heating on a low setting you can reduce the amount of moisture in the air
- Letting air into a room by opening a window or a door
- Making sure ventilation grills in doors, windows or walls are not locked
- Not using bottled gas heaters.
If mould does form within your home wipe it off immediately using water, then apply a special solution available from most DIY stores.
