Condensation

What is condensation?

Condensation is the appearance of water on cold surfaces. It occurs when the temperature of moist air drops as it comes into contact with air, or a surface, which is at a lower temperature.

Water produced from condensation is generally noticeable where it forms on non-absorbent surfaces (i.e. windows or tiles) but it can form on any surface and it may not be noticed until mould growth or rotting of material occurs.

Why does it matter?

Condensation can make the property less pleasant to live in and cause damage to a property. To avoid unnecessary costs, it is important that you take steps to limit condensation build-up.

How can you reduce condensation?

Prevent High Moisture Levels

Some normal daily activities produce a lot of moist air very quickly. To minimise the amount of moist air, which leads to the formation of condensation, please note the following:

  • Cover pans when cooking and kettles when boiling water. Only keep them boiling for as long as required.
  • Avoid using paraffin and portable bottle gas heaters.
  • Dry washing outdoors if possible. If it’s raining or too cold, use the clothes airer or radiator airer we provide in the bathroom with the door closed and the window open or fan on. If a clothes airer or radiator airer were not provided when you moved in please contact us.

  • Do not dry washing directly on room radiators as this releases large amounts of water vapour into the room. As the radiator is covered it cools the room at the same time which also makes condensation far more likely to happen. The increased moisture in the air helps mould to develop.
  • Run the cold water first when filling a bath as it prevents steam production.
  • Potted plants continuously release moisture. Over 24 hours any room with multiple potted plants will experiences similar moisture levels to those activities normally associated with condensation such as showers and cooking. Ensure that potted plants are removed from rooms experiencing condensation.
Manage Home Heating

During periods of colder weather, preventing sudden drops in temperature or frequent changes in temperature can stop or reduce condensation. Condensation is less likely to form in warmer houses so keep the heat on low all day.

You can control both the temperature and timing of your heating with the following:

  • Boiler settings
  • Room thermostat settings.
  • Radiator thermostat settings

Ventilate to Remove Moisture to the Outside

Your home can be ventilated without creating draughts by:

  • Keeping a small window open a little, or opening a window ventilator when the room is in use.
  • Opening the kitchen or bathroom windows to let steam and moisture out.
  • Dry washing outdoors if possible. If it’s raining, use a clothes airer in the bathroom with the door closed and the window or fan open.
  • Use an extractor fan, they only use a minimum of energy. If your any of yuor extractor fans are not working then please contact us.
  • Ventilate your bedroom by leaving trickle vents or a window slightly open with a 2 inch (5 cm) gap.
  • Closing the kitchen and bathroom doors when the rooms are in use to stop the warm moist air producing condensation in other cooler rooms.
  • Don’t clutter wardrobes and cupboards, it stops air circulating.
  • Don’t block ventilators, air bricks and chimneys.
  • Dry your windows and windowsills every morning.
  • Don’t push beds, furniture, sofas or store items against outside walls which are always colder and attract condensation. Make sure there is at least a 12 inch (30cm) gap. Bedding can get damp if air cannot circulate around it.
