Condensation is present when water collects on a cold surface and interacts with humid air. A lack of ventilation is the main cause of condensation.
Some damp is caused by condensation, which can then lead to a growth of mould. Mould growth can contribute to health problems for occupants, such as asthma and respiratory diseases.
Our daily routine consists of showers or baths, boiling kettles, cooking, drying, washing and breathing. This will create four pints of water per person per day, which has to go somewhere. The more moisture there is in the air, the more likely you will get condensation. Many houses are now double glazed and have loft insulation, trapping air that will inevitably turn into condensation.
When cooking, boiling the kettle or showering, make sure you keep the door closed to prevent steam escaping into colder areas of the house. Always cover pans with a lid to reduce moisture. Open windows as often as you can to let in fresh air. When running a bath, always start with the cold water tap as this will reduce steam.
When showering or cooking, switch on extractor fans to take moisture from the air, leaving it on for an extra 15 minutes when finished.
Air vents and air bricks are there to circulate air through the property. Blocking them prevents the moisture from escaping. Always keep them clear for maximum condensation control.

Ensure that your tumble dryer is correctly vented to the outside.
If you need to dry clothes indoors, make sure a window or door is left open to circulate fresh air.
Avoid using paraffin heaters and bottled-gas heaters as they produce a lot of condensation. It is cheaper to heat a room using on-peak electricity than by using bottle gas heaters.
Keep your heating on low throughout the day in cold weather as an even temperature reduces cold spots. Don’t place large pieces of furniture in front of radiators as this can stop heat circulation.
Moisture production is influenced by a home’s occupants, activities undertaken within the property and also by the design, construction and disrepair of the property. Some simple changes in lifestyle can help reduce condensation and make the home more energy-efficient.
