Why Are My Windows Sweating?

There are a few reasons why your windows might be sweating. The most common reason is that there is too much moisture in the air inside your home. When warm, humid air builds up in your home and touches the surface of your cool windows, it causes the moisture to condense on the surface of the glass and causes sweating. This can be unsightly, ruin your view of the outside, and also lead to mold and mildew growth.

This can happen for a number of reasons, including:

  • Cooking or bathing, which produces steam.
  • Running a humidifier.
  • Having a lot of plants in your home.
  • Living in a humid climate.
  • Having poor ventilation inside the home.

If you're concerned about condensation on your windows, there are a few things you can do to reduce the amount of moisture in your home. These include:

  • Opening your windows and doors to ventilate your home.
  • Using a dehumidifier.
  • Taking shorter showers and baths.
  • Reducing the number of plants inside.
  • Moving the rest of your plants away from your windows.
  • Increasing ventilation in your home.

If you've tried these steps and you're still having problems with condensation, chances are you need to have your windows replaced. Newer windows are often made with materials that are more energy-efficient and that help to prevent condensation.

Here are some additional tips to help prevent condensation on your windows:

  • Clean your windows regularly. This will help to remove any dirt or grime that could be trapping moisture.
  • Install window treatments. Window treatments can help to insulate your windows and keep the heat in during the winter and the cool air in during the summer. This can help to reduce the amount of moisture in your home.
  • Seal any air leaks around your windows. Air leaks can allow moisture to enter your home, which can contribute to condensation. You can seal air leaks with caulk or weatherstripping.
  • Use a whole house fan. Whole house fans exhaust hot, humid air out of the house and replace it with cooler, drier outdoor air. Whole house fans are extremely energy efficient and can reduce your electricity bill. They work best on cool nights or when the indoor temperature exceeds the temperature outside. Plus, they’re perfect for reducing the humidity inside the home. Whenever moisture builds up inside, all you have to do is turn on your whole house fan. Whole house fans expertly ventilate the home to keep it more comfortable, cooler, and drier delivering a cool breeze throughout your home. Choose the perfect whole house fan for your home here.

If you have tried these steps and your windows are still sweating, you may need to replace your windows with ones that have a higher energy efficiency rating. These windows will help to keep the warm air inside your home and the cold air out, which will help to reduce condensation.
