How to Stop Condensation on a Single-Pane Window
- 1). Turn on bathroom and kitchen exhaust fans after taking a shower or bath, and after cooking, washing the dishes or running the dishwasher. Leave the fans on for a minimum of 10 to 15 minutes to remove the excess moisture which contributes to condensation buildup.
- 2). Plug in a dehumidifier and place it in the room where the majority of condensation problems occurs. Turn the unit on and run it for one to two hours per day. Increase the amount of time it runs per day until no condensation forms on the windows. Empty the collected water from the dehumidifier tank at least once per day.
- 3). Open all curtains and blinds in the morning as soon as the sun rises to help remove moisture and dry out the interior air.
- 4). Examine the inside and outside edges of the window frame carefully to identify areas of cracked or peeling caulk. These areas can allow cold air in which creates condensation inside the window. Scrape off any damaged caulk with a putty knife and apply a thin bead of white or clear caulk over the area and smooth it with a caulk smoothing tool.
