Most problems can be resolved quickly and simply, once you know how. The information below will guide you through the most likely problem areas and help you take appropriate steps to prevent problems, or deal with them if they occur. Condensation is the result of moisture-laden air being below its 'dew point' by contact with cold surfaces such as glass, walls or ceilings. Condensation occurs because air is unable to retain water vapour, resulting in the appearance of water droplets. Water vapour is always present in the air but in variable quantities, depending on seasonal conditions and your habits.
Warm air can absorb more water vapour than cold air.
Due to differences in vapour pressure, water vapour can travel from room to room throughout the house. For example, water vapour can travel from the laundry or to other rooms in the home. Condensation isn't always visible and can occur on absorbent surfaces such as clothing, upholstery and curtains. It can also turn up inside panelled walls and timber floors, with the potential to cause damage. Main problem areas Surfaces most likely to be affected by condensation are glass, cold walls and ceilings.
