What to Know About Summer and Winter Window Condensation

Condensation refers to vapor turning into liquid water when it comes in contact with a surface. Some of the examples that we see on our daily surroundings include dew forming on the grass in the morning, bathroom mirrors fogging up when you take a shower or droplets shaping up on the surface of a glass during a hot day.

The same thing happens to windows, particularly in winter. Not everyone knows, however, that it can also occur during summer. Window condensation during winter and summer differ in some ways, though. Renewal by Andersen® of Atlanta, the leading local windows company, discusses their differences, as well as gives tips on how to combat them.

Summer and Winter Condensation: How Do They Differ?

The key difference between window condensation in summer and winter is where it appears. Summer condensation occurs outside your windows, while its winter counterpart appears inside. This means a lot of things. During summer, the condensation is purely visual, meaning it won’t cause major issues. Winter window condensation, on the other hand, can cause wood rots, eventually affecting your units’ performance. Additionally, due to the presence of moisture, mold and mildew – which is a potential health risk – can grow inside your home.

Ways to Combat Condensation

As your trusted windows contractor, we recommend doing the following:

  • Lower your thermostat.

  • Clean your air vents and change your filter.

  • Make sure ducts are always sealed.

  • Get a dehumidifier.

  • Ventilate the air in your home daily, even if for a few minutes.

  • Invest in replacement windows that have gas-filled insulated glass and low-E coatings.

If you’re on the lookout for high-performance replacement windows, you can always turn to Renewal by Andersen of Atlanta. We offer top-of-the-line replacement windows equipped with the right features to combat condensation, no matter the season.
