How to avoid condensation this winter?

Nothing is more beautiful, than a crisp sunny winter morning when you watch the Sun comes up. That is when you can see through your window or patio door and your view is not obstructed by water drops or in worse cases some water raining down in the inside of your window…
If you experience this, your home is most likely affected by condensation.

What is condensation?

When humid air gets into contact with a cold surface such as poorly sealed windows, the water precipitates in form of water droplets. Condensation is a phenomena to take seriously. Although you might think you just wipe away the moisture and you are done, in reality it can cause dampness, mould health issues, wood rot and corrosion. In the long run it affects the walls by weakening, discolouring them and by layers of the wall painting peeling off. It is not only an aesthetic issue but can also cause serious health conditions such as asthma.
On the other hand condensation is an indicator of increased heat transfer which means poor insulation and unfortunately also means higher heating bills.

What generates moist air in your home?


We collected the most common causes that form moist air in your home:

  • Normal breathing and perspiration
  • Cooking, especially without lids
  • Taking a shower or bathing
  • Drying clothes inside
  • Failing window seals
  • Poor insulation
  • Soil moisture
  • Indoor plants and pets

Where do you find signs of condensation?


The first indicators of condensation are the water droplets on your window glaze. At the same time there are other indicators as well:

  • Faulty smell: when dampness and moulding occurs, you can smell it in the air
  • Damp patches on the external walls, on the ceiling, in the corners of rooms
  • Black mould on walls, window frames, in cupboards and on curtains or clothes
  • Paint peeling off of walls and door or window frames

8 steps to stop condensation


Because everyday life phenomena such as breathing produce moisture as well, it is fair to say that it is impossible to avoid moist air in your home. However you can prevent the condensation with our tips below:

  1. Ventilation is key. Open your windows every few hours to get rid of the humid air. If you have drip vents in your windows it is wise to keep the vents open at all times.
  2. Keep the temperature in your property constant and measure humidity level. You can also use a dehumidifier additionally in the cold months.
  3. When cooking or taking a shower always make sure to use extractor fans and open the windows as well. Shut the kitchen or the bathroom doors to avoid moist air entering into other rooms of your property.
  4. Dry your clothes outside as much as you can or alternatively use a tumble dryer. Ensure that the ventilation pipe of the tumble dryer is installed outside of your property.
  5. Make sure your closets and cupboards are not too cluttered and stuffed so air can circulate properly. For the same reason move your furniture away from the walls as well.
  6. Check your extractor fans and other ventilation airways of your home regularly to ensure moist air leaves your home and don’t cause condensation.
  7. Check your window seals and overall insulation and ventilation of your home.
  8. Get new windows and patio doors fitted in if necessary. New windows and doors help to prevent condensation and they are also more energy efficient to keep the warmth inside in the winter. If you decide to go for a new window or door replacement make sure you use high quality and well respected suppliers to avoid disappointment.
