What is condensation?

Condensation starts as moisture that is produced by cooking, washing, or by drying clothes indoors or on radiators. The moist air condenses on cool surfaces such as walls, mirrors, wall tiles and windows.

Signs of condensation include water and mould collecting on ceilings, walls or windows.

All homes suffer from condensation from time to time, but severe condensation is common in cold weather and in older properties.

If mould forms

• Wipe the mould off with antifungal solution (not washing-up liquid or water) and then apply a sealant solution to the wall. (You can get these sealants from hardware or DIY stores – but always read and follow the instructions carefully)
• If you do not remove mould quickly, it can spread onto your personal belongings

What can I do to reduce condensation?

Control moisture:

• close kitchen and bathroom doors to prevent steam going into other colder rooms
• open kitchen and bathroom windows when cooking or washing so that steam can escape, or use an extractor fan if you have one fitted
• open some windows in other rooms for a while each day to allow a change of air
• wipe down surfaces where moisture settles to prevent mould forming
• don’t block air vents
• don’t use bottled gas heaters; they produce a lot of moisture

Produce less moisture:

• dry clothes outdoors wherever possible, otherwise use well-ventilated rooms
• cover pans when cooking
• vent tumble driers to the outside

Keep your home warm:

• take steps to prevent heat loss
• keep a low background heat on for longer. This won’t necessarily cost any more.
