Window condensation is an unpleasant problem in many newer homes due to tightly sealed and well-insulated windows. Condensation occurs around the windows when water changes from its gas state to a liquid state. Water vapor turns into liquid when it comes into contact with a cold surface; for example, during the summer condensation can occur if the air in the home is overly cool and comes into contact with a warm window.

Quick Ways to Eliminate Window Condensation:

If the condensation is mild and does not occur often, there are easy and quick ways to rid the home of excess moisture. You can purchase a dehumidifier, which works to reduce the amount of excess water vapor in the home. If you own a chimney, you may want to have the flue checked. A clogged flue can also cause problems with excess moisture in the air. One of the quickest ways to reduce condensation is to simply open a window about an inch. This helps the air to circulate and the cool air to mix with the warm air, equalizing the temperature.

Remove Obstructions:

If these quick fixes do not rid your windows of condensation, you may need to inspect the problem further to isolate the cause of the condensation. Curtains, window blinds, shades, and other window coverings can block airflow across the glass of the windows and cause condensation. Removing these obstructions from the window can reduce or eliminate the amount of condensation. Other companies produce wipes and sprays that help to reduce condensation.

Commercial Products:

Many home improvement stores sell commercial products that are made specifically for reducing and eliminating window condensation. Some manufacturers such as 3M make a window film kit that helps to eliminate window condensation. Rain-X brand manufactures a Glass Anti-Fog that you can apply to windows in the home or car, mirrors, and any other glass surface that tends to accumulate moisture. Simply wipe the solution onto the surface with a clean, soft cloth or paper towel. These types of products may not work well in extremely cold or humid conditions and may need more than one application.

Lower the Humidity:

There are two simple ways to lower the humidity within the home – either increase the air temperature or decrease the moisture in the air. By increasing the air temperature in the home, the humidity will lower. The dew point, or the amount of water in the air, however, may not be changed. If the dew point remains the same, condensation will still appear even with an increased air temperature.

Unfortunately, lowering the humidity within the home can be difficult. If there is too little humidity, the air can become dry, filled with static electricity, and uncomfortable. Installing and using ceiling fans throughout the home and exhaust fans in both the kitchen and bathroom help to circulate the air and reduce humidity. There are many different varieties of controlled ventilation systems that can be installed in the home to regulate the humidity, eliminate condensation, and keep the home comfortable. Replacing the windows in the home is always a last resort. This can be costly and you will need to research the best types of windows for your climate, location, and lifestyle.
