Often occurring in winter, condensation on the inside of your windows and on other areas of your home happens when water vapour in the air meets a colder surface.  Windows are the most common location within a home for condensation to form because window panes are generally the coldest surface in the interior.

Condensation on the exterior of your windows is just dew and occurs when the window surface is colder than the dew point.

Internal condensation is more of an issue in winter because the warm air in your home holds more moisture than cold air and the temperatures outside are lower and therefore the surfaces are colder.

How can you effectively reduce condensation?

  • Provide adequate ventilation and cross ventilation. Open the windows whenever you can on warmer days.
  • Ensure your property has sufficient heating as this will reduce the likelihood of condensation when internal surfaces are warmer.
  • Control humidity by using extractor fans in bathrooms and kitchens and keep lids on pots and extractors on during and after your cooking time.
  • Make sure that your washing machine and tumble dryer are correctly vented; a load of washing can result in two litres of water being released into the air.
  • Try not to dry washing indoors but if this is not possible then isolate the washing into one room and leave the windows open and close the door.
  • If you do not have an open plan kitchen then close the door whilst cooking to prevent the moisture migrating into colder rooms thereby causing a build-up of condensation. For the same reason close the bathroom door whilst showering and if condensation forms on the wall then wipe it dry.
  • Cover any fish tanks and aquariums to avoid excess moisture.
  • Open blinds and curtains because heavy covering will restrict warm air flow over the interior glass surfaces.
