Condensation Considerations

Condensation occurs when the surface temperature of the window is cool and the interior of your home is warm and humid, due to a lack of ventilation.

Windows are often mistaken as the problem, as they are the first place condensation can be seen, but what about between the walls and in the insulation? The moisture is there too. Your windows may actually be serving as a warning sign.

Here are a few tips to prevent excessive humidity in your home:

  1. Try to open up your windows and doors from time to time (yes, even in winter) to let some fresh air in.
  2. Open up windows and doors when using your clothes dryer to prevent the moisture from the clothes being released into your home.
  3. Use your bathroom exhaust fan during and after showers and baths, provided they are vented externally and not just into your roof cavity.
  4. Increase the temperature of your home by a few degrees to prevent water condensing on cold surfaces.
  5. Use a fan in rooms where the problem is excessive or use the dehumidifying setting on your air conditioner.
  6. To avoid any residual problems, wipe down any wet surfaces to keep them as dry as possible.
