The formation of condensation is a result of moisture in the air of the house being deposited on cold surfaces.

This is most commonly seen on windows; however, it will also affect walls, inside cupboards, clothes and shoes stored in wardrobes, and soft furnishings.

Prolonged condensation will allow mould spores to germinate leading to the characteristic black appearance on walls, quite often in corners or behind furniture. There can also be a ‘musty’ smell if the property is shut up and a damp feeling on sheets, chairs etc.

Alleviating condensation and the associated dampness and mould growth can be problematic.

Modern house construction or home improvements like double glazing, draught proofing and blocking up fireplaces can reduce ventilation in the building whilst normal everyday living, showers, cooking, and even breathing add moisture vapour to the atmosphere.

Generally, a balance of heating and ventilation will control condensation to a level where it is not a problem but, in many cases, this cannot be achieved naturally and assistance is required in the form of a ventilation system.

Positive Pressure units are a very good, long term solution to ventilation problems whist the installation of specially designed air bricks (Passyfier vents) can provide air movement in limited spaces.
