Condensation along the inner surface of the windows or window condensation is a common, window-maintenance issue. Condensation is visible in the form of small droplets of water or an easily-detectable, damp layer along the windows interior surface.
This indicates excessive humidity and poor air circulation within the house, causing retention of moisture/water-vapor. Window condensation is deemed harmful because it causes sustained seepage of moisture along the windowpanes and drywalls around the windows.

Mildew development is more common among walls sections around windows having chronic, interior-condensation issues. However, interior window condensation can be easily prevented by adopting the following, two measures.
