Condensation forms when the temperature drops and the air no longer can hold the moisture it is carrying. It collects as small water droplets on windows, walls, tables and other furniture. Excessive moisture can lead to wood rot, mold and fungus. This slowly eats at the structure of the house and can cause the occupants to get sick. Control condensation by eliminating any sources of moisture and removing it from the air with a dehumidifier.
Locate and remove any sources of moisture in your home, if possible. Items you can eliminate are plants, stored firewood and dirt basement floors.
Open windows and turn on the furnace's fan to circulate the air. If you have mechanical ventilation in your bathrooms, turn on the fans.
Install a dehumidifier in the low areas of your home such as basements. Empty the dehumidifiers on a regular bases.
Turn on your stove top's ventilation fan when cooking. A significant amount of moisture is released when heating food.
Turn on your home's air conditioner. AC systems remove moisture from the air by cooling it. The condensate is then removed from the home via the plumbing system.
