What causes condensation?

What causes condensation? From a technical point of view, condensation is caused when warm, damp air (humidity) is released into the atmosphere in our homes. This normally happens when the water laden air comes into contact with cold surfaces such as windows and cold walls.

From a more down to earth human nature perspective however, condensation is typically caused through unavoidable daily tasks within everyday living.  This includes such things as:

  • Boiling water
  • Cooking
  • Bathing and showering
  • Washing and drying clothes inside
  • Certain forms of heating such as paraffin and gas heaters
  • Even the act of breathing contributes to water vapour in the air  

It is estimated that a family of four will produce the equivalent of 100 pints of water a week through such routine activities.

The leading cause of condensation

Whilst condensation occurs in every home, the leading cause of condensation developing is a lack of proper ventilation and circulation in the property.

As we increasing look to insulate our homes through double/triple glazing, draft proofing, etc; it has the knock on effect of trapping the moist air within a property. Without a source of air ventilation that would help to naturally push the moist air out of the property, the moist air becomes trapped.  Eventually, the moist air will come into contact with a colder surface long enough for the dew point to drop, resulting in condensation water beads forming.  Given time, this condensation moisture will fester leading to black mould.

Does the weather cause condensation?

Condensation is known to effect properties more in the colder months from October to April (known as condensation season) than it is during the summer period (however brief that may be!).

Since we naturally prefer to stay warm by turning up the central heating and keeping our windows closed when it is cold outside, we introduce greater levels of humidity into the home. When the outside temperature drops you may start to see water appear inside your home, especially on windows, walls and in the loft.

Stopping the causes of condensation

More often than not, simple lifestyle choices can go alone way to helping alleviate the cause of condensation.  As individuals, we are still going to continue showering, cooking and drying clothes.  However, by changing a few habits in the home and by following a few hints and tips; it can go a long way to reducing the excess moisture within your home or property.  Click to visit our how to stop condensation web page for a helpful free guide on what you can do.
