Condensation occurs when high levels of humid air are trapped within a building, where poor ventilation does not allow it to escape. This moisture then condenses when it touches cold surfaces such as windows or walls; eventually leading to mould growth.
Improving insulation, double glazing and draught proofing can reduce the natural ventilation in properties and therefore lead to the build up of water vapour.
Air can only hold a certain amount of moisture 'water vapour' - the warmer the air the more it can hold. If this air is then cooled by contact with a cold surface (a window, mirror, metal window frame or outside wall) the vapour becomes water droplets - condensation.
The point at which the air cools enough for the water droplets to form is known as the 'dew point'.
Everyday activity like cooking, washing, bathing or even just breathing, releases moisture into the air. An average family of 4 can generate approximately 24 pints (14 litres) of water a day.

Condensation is most noticeable during the colder winter months of October to April, when windows are generally kept closed to keep the warmth in. Obvious places condensation can appear - apart from windows, are cold walls and floors. Sometimes it can occur in hidden areas such as roof voids or under suspended floors. Timbers in these particular areas may become susceptible to rot problems.
Most properties will suffer from some condensation over time. However it becomes an issue if it is persistent and leads to other tell-tale signs such as:
There are several steps you can take to reduce the likelihood of condensation becoming a problem, however they may not be practical all of the time:

Mould spores are known allergens. Their microscopic spores are often powdery and become airborne at the slightest disturbance. These microscopic spores are then inhaled by humans and have been attributed (along with the dust mite) to being a trigger for asthma, dust allergies and hay fever.
Dust Mite increase when properties remain damp.
