Air moisture condensation takes place during the colder months (from October to April) and is known as the ‘condensation season’.

When the temperature of the air drops, it cannot hold all the moisture and tiny drops of water may appear on walls and especially windows. Constant condensation leads to mould and bad damp which creates a particularly unpleasant smell which finds its way into clothes and books.

The solution is to ventilate rooms daily when the property is occupied. In very cold weather this is not always possible so here are some hints that may reduce the problem.

– Wipe off condensation from windows on a daily basis. Mould should be washed off with a solution of 1 part bleach, 10 parts water.
– Clothes should not be dried over the radiator
– Place clothes on a drying rack in a well-ventilated room
– Tumble dryers should be properly vented
– Existing extract fans should not be disabled
– Extract fans should be used when cooking or showering
– Keeping the lid on a pan while cooking will help to avoid excess steam
– Try keeping heating low at all times as constant, sudden changes in temperature bring more condensation. It is also more economical than turning systems on and off.

Given that moisture travels around the building, the room in which condensation is actually taking place may sometimes be far removed from the origin of the moisture, usually caused by cooking, drying cloths and washing.

Bathrooms and kitchens are always a problem. In both cases ventilate after use for at least half an hour. Keep a close eye on mould growth, and wash off as soon as possible. Try to keep furniture away from outside walls in particular, and pull them away from walls in general to allow the air to circulate around them. When drying clothes you should try at all costs to keep a window open as this is often the worst cause of condensation.

Damp patches on walls may be caused by penetrating damp. A quick test is to stick cooking foil to the wall, sealing the edges with masking tape. Leave for 24hrs. If there are beads of moisture on the side that has been up against the wall, then damp is coming from outside. If moisture appears on the side away from the wall then it is condensation.

Do not ignore condensation. Over time it can cause damage to the property, and also affect your health. It can particularly affect asthmatics. We would be glad to give you advice and assistance, but with condensation it is usually the case of working good living habits into your everyday life.
