Understanding the Causes of Window Condensation

Homeowners who have recently installed high-quality Renewal by Andersen® replacement windows in Scranton sometimes contact us at this time of year, concerned that their lovely new windows are covered in condensation. While it is true that this problem can be caused by a broken seal, the culprit is usually not the window: it’s the humidity in your home. Here are some of the common causes of high humidity and what you need to know to prevent condensation from fogging up your view.

Window CondensationHigh-Moisture Activities

Cooking, bathing and showering are the activities that release the most moisture into a home. It’s very important to have working exhaust fans that are vented to the outside to draw the excess moisture out. Always use the exhaust fan above your stove when cooking, and turn on your bathroom exhaust fan while showering or bathing. The fan should be left on until the mirror is clear again. This will also help prevent mold and mildew. In addition, check to be sure that your dryer is vented properly, since clothes drying also releases a lot of moisture.

Attics and Crawl Spaces

In most areas, it is smart to also vent attics and crawl spaces to the outside. For crawl spaces, it’s important to put down a good vapor barrier to block moisture from coming up through the ground and into your home.

Blinds and Window Treatments

Curtains, drapes and blinds can contribute to the buildup of interior condensation by preventing warm air from flowing over the window. To avoid this, simply keep windows uncovered as much as possible during the winter months. This will have the added benefit of letting in the sun to help warm your home naturally.

Insect Screens

Sometimes interior insect screens can block the flow of air as well. Since there are no insects to worry about during the winter in most areas, consider removing and storing your insect screens.

Reviews

"Our installation team, Josh and Mike, did a phenomenal job with the installation, cleanup, and "orientation" after the work was completed! We were totally satisfied with everyone that we dealt with before and after the installation...and would surely recommend Renewal by Andersen to anyone contemplating a window replacement project!"
