How to Fix Condensation in Windows

Window condensation is generally prevalent during the fall and winter months. Condensation forms when the moisture in the air comes in contact with a cool window. The air touches the window, gets cooled and releases drops of moisture on the window, resulting in condensation. Newer homes have more problems with condensation, because the walls are so insulated, making them much warmer than the windows. Window condensation may seem like a small problem, but it can eventually lead to mold, which is a serious health risk. It's important to get rid of condensation quickly to avoid bigger problems in the future.

Things You'll Need

• Dehumidifier
• Hygrometer

Instructions

1. Keep the stove exhaust fans running when you cook. The steam from the cooking rises up into the air and accumulates on your windows and walls. Using the bathroom exhaust fan while taking a shower will prevent the steamy air from ending up on your windows. Exhaust fans pull the moist air up and out, which reduces excess moisture inside your home.

2. Turn on ceiling fans to circulate the air. If the weather is nice enough, opening a window several inches helps prevent condensation as well.

3. Use a dehumidifier to remove moisture in the air. If you have a large collection of houseplants that you just can't bear to part with, a dehumidifier will help to counteract the extra moisture that the plants add to the air.

4. Open the drapes and blinds to allow warm air to reach the windows. Also, avoid turning the thermostat down too low. Cold air doesn't retain as much moisture as warm air does, so the condensation will quickly cling to the windows.

5. Maintain the level of humidity in your home at approximately 40 percent during the winter. To measure the humidity level, purchase a hygrometer from a home improvement store. Also, turn off humidifying devices such as furnace humidifiers.

6. Open fireplace dampers, and vent clothes dryers and gas burners to the outside. This keeps the moisture-laden air flowing out of the home.
