What Causes Moisture Build-Up Inside Windows?

Moisture build-up inside windows is usually caused by condensation. Condensation occurs when warm, moist air comes into contact with a cold surface. When this happens, the moisture in the air condenses on the surface, forming droplets of water.

During the winter months, when temperatures outside are cold, and indoor heating is turned up, the temperature difference between the inside and outside of your home can cause condensation to form on your windows. This is true if the humidity level inside is higher than it should be. Also, if you have older windows with non modern insulation techniques, as they are more likely to be colder than the rest of your home. Modern windows will have at least a double pane and inside the 2 panes of glass is gas or air. This creates a barrier between the outside and inside pane of glass and serves as a form of insulation.

As already mentioned among the other causes of water on windows is high humidity levels in your home. Also cooking or showering without proper ventilation, or drying clothes indoors. These activities can release moisture into the air, which can then settle on your windows.
