Unfortunately, condensation is a common modern problem. It can occur where warm moist air meets a colder material. Whilst windows are often seen as the cause, they rarely are. The colder surface of the glass and wall around the window simply indicate a problem that exists within a property.

Modern homes are now better insulated than ever but this does mean moist air can then be trapped inside.

Abbey’s Advice

  • Open windows (even slightly helps) when possible and open interior doors. This helps circulate air through the property.
  • Avoid drying washing inside. As all that water has to go somewhere.
  • If you have a radiator under a window, do not hang curtains over the radiator. This simply directs heat onto the window rather than into the room.
  • Try turning the heating down when possible (even if just certain rooms).
  • Ornaments on a window ledge in a damp area can trap damp air, further increasing mould issues.
  • Ventilators in glass or trickle ventilators in the top of the window frame can help circulate air and often reduce condensation (both of which we can install).
  • If you have tried the above tips and condensation is still a problem, try renting a dehumidifier. This will reduce moisture from the atmosphere inside your home. If it works, invest in your own dehumidifier.
  • If condensation is worse after replacement windows, it is usually due to the fact that your new windows have better seals than the originals that were simply letting moist air out.


Mould can feed on damp areas, leading to health issues. You must treat condensation as an indicator of a problem within your property that that could affect health, walls, curtains, carpets and upholstery.

External Condensation

All newly fitted windows and doors now need to contain energy saving glass to comply with Building Regulations. This is called a Low E (Emissivity) glass and works with a fine reflective coating in the same way as a Thermos flask by reflecting escaping heat back into the room as it tries to escape. Under certain weather conditions, condensation can occur when a cold external glass suddenly warms up when there is moisture in the air. This is usually when the sun rises on a cold day and the air is damp. As the glass continues to warm through the day, the condensation will disperse.

Unfortunately, it is not possible to predict when and to which windows this may occur and we are unable to guarantee against it happening or take any action to stop it if it does. As the use of this glass is now standard for our whole industry, it could affect any window from any company that correctly follows Building Regulations. Whilst we appreciate temporary condensation may appear unsightly, it will disperse and is a good indicator that the window is working at reflecting heat back inside the property (albeit it from the outside in this temporary instan
