Minimizing Indoor Humidity and Condensation on Windows

Condensation on your windows can be completely harmless in some cases. In other cases, however, it can be a sign of damage to the window.

Minimizing Indoor Humidity And Condensation On Windows

Window contractors will tell you that in order to minimize condensation forming on your windows, you need to reduce the amount of humidity in your home. Here are a few ways you can reduce indoor air humidity, helping prevent condensation.

1. Make sure your house has adequate ventilation.

Proper ventilation helps lower indoor air humidity by driving it outside the house. Vent all gas appliances, clothes dryers and exhaust fans to the outside of your home. If you are using a forced ait furnace, make sure your home is properly ventilated.

If it’s not that cold outside, you can open your replacement windows to let warm, humid indoor air escape your home.

2. Use exhaust fans.

Bathing, taking a shower, cooking — all of these things increase the levels of humidity in your home. Exhaust fans help remove the moisture in the air. Run the fan during and after you cook. Also, run your exhaust fan when taking a shower, and leave it on until the condensation in your bathroom mirror is gone after you’re done.

3. Ventilate hard-to-reach areas.

Attics and crawl spaces need to have adequate ventilation to allow humid indoor air to escape. Covering the earth in your crawl space with a good vapor barrier will also help prevent moisture from entering.

4. Store firewood outside your home.

Depending on how “seasoned” it is, firewood is likely to contain some amount of moisture. Storing firewood outside the home will help lower the amount of indoor air moisture.

Doing these things will help prevent condensation on your windows. If you’ve done all of these and condensation continues to form, then maybe it’s time to consider having your windows checked; you might be in need of new windows.
