How to Stop Interior Windows From Sweating

Dry windows will help you make a healthier home.

Interior window sweating is basically a reference to an accumulation of moisture on the inside of the various windows in your home. This can become an issue quickly if the interior window sweating is not stopped in a timely manner. Excessive moisture can cause mold and mildew to form. This is the main concern with interior window sweating. Damage to the paint or finish is also a concern, as well as issues with freezing water in the winter.

Things You'll Need

• Exhaust fan
• Dehumidifier
• Vents

Instructions

1. Run the exhaust fan in areas of your home that build up a great deal of humidity, which contributes to interior window sweating. You might have an exhaust fan in your bathroom, laundry room or above your stovetop.

2. Allow the exhaust fan to continue running for about 15 minutes or until all of the condensation on the windows is gone.

3. Cool down your home. If your thermostat is on a lower temperature, such as 66 to 68 degrees Fahreheit, rather than about 75 degrees Fahrenheit, your interior windows will be less likely to sweat.

4. Vent clothes dryers and gas fireplaces outdoors. This may require professional help, particularly with the gas fireplace. If these areas are improperly vented, you won't be able to stop the interior window sweating.

5. Run a dehumidifier near the interior windows that sweat most often. A dehumidifier removes moisture from the air, which will stop it from accumulating on your windows.
