Condensation occurs on windows when temperature and humidity changes occur within your home.

Typically, this will disappear throughout the day as it warms up and the condensation evaporates.
Sometimes, condensation is caused by a problem with ventilation in your house. When the internal air can't be properly aired out, moisture will find its way into your insulated glass unit (IGU) where it will result in a build-up of condensation.
