How mould issues start
Condensation starts as moisture that is produced by cooking, taking a bath, having a shower or drying clothes indoors. The moist air can condense in unheated bedrooms, bathrooms, kitchens or other rooms on cold walls, ceilings or floors and then forms mould.
How to avoid condensation
Our top tips to avoid condensation are:
- cover pans when cooking and switch off kettle once they have boiled
- don not use portable bottle gas heaters – the gas produces a lot of moisture
- dry washing outdoors on a line, or use a drying rack in well-ventilated rooms
- vent your tumble driers on the outside, unless it is a self-condensing type
- wipe down surfaces where moisture settles to prevent mould forming
- when you use your bathroom and kitchen close the room door and switch on the extractor fan, if one is fitted, or open the window so that steam can escape
- open windows in each room for a while each day to allow a change of air
- make sure permanent ventilators are not blocked
- leave a space between the back of wardrobes and walls to allow air circulation. Where possible, position wardrobes and furniture against internal walls
- keep your home warm and take steps to reduce heat loss. In cold weather, keep low background heating on all day, or as much as possible
First steps against mould
You can start by:
- dealing with the basic problems of condensation
- killing and removing mould, wiping down affected areas with fungicidal wash, available from DIY stores - following the manufacturer's instructions
- redecorating using a good-quality fungicidal paint to help prevent mould recurring after treatment
