Condensation is by far the most common cause of dampness in buildings, probably accounting for the majority of damp problems that get reported. It affects both old and new buildings, but studies have shown that it can be a significant problem where buildings have been modernized.
How to reduce condensation in your home:
Control excess moisture
- Close kitchen and bathroom doors to prevent steam going
into colder rooms.
- When cooking or washing, let the steam escape by
opening a window or using an extractor fan if you have
one fitted. Leave the window open or the extractor fan on
for up to 20 minutes after you have finished cooking or
- Open some windows in other rooms for a while each day and open any trickle
vents in your window frames. This allows the air to circulate within your home.
- Wipe down surfaces when moisture settles to prevent mold from forming.
- Do not block any ventilation to allow air to circulate around your furniture.
- Do not use bottled gas or paraffin heaters, as they create a lot of moisture and they are a safety risk.
