Should You Be Worried About Condensation on Your Windows?

Many people regard condensation on windows as a problem. If you’re one of them, we have good news: condensation isn’t a problem most of the time. In today’s post, the window and roofing contractors at Kroll Construction share a look at the causes of window condensation, and why you shouldn’t worry about it.

Condensation is formed when moisture in the air comes in contact with a cooler surface. As moisture collects on this surface, it forms droplets that become noticeable as condensation. A cold glass of water left on a countertop forms condensation not from the contents of the glass, but from the moisture in the air. If you leave a cold room while wearing eyeglasses, moisture in the air would collect on the still-cold lenses, resulting in foggy glasses.

The same thing happens on windows. During the winter season, it’s not uncommon for moisture to form on closed windows. You might also find some condensation on the outer side of your windows during summer, when moisture doesn’t evaporate fast enough. The good news is that most of the time, condensation is an indicator that your windows are sealed tight as they should be.

What You Should Do When You See Condensation on Your Windows

Generally, condensation shouldn’t be ignored, especially when you find it in areas such as under your roofing system. While condensation on windows, as described above, doesn’t always indicate problems with your windows, it does indicate high relative indoor humidity. This means you have to change a few things to reduce humidity in your home. If you use a humidifier, make sure it’s set around 50%. Using exhaust fans when you use the bathroom and kitchen also helps maintain indoor humidity levels and reduce condensation.

There is one exception about window condensation that you should know. Insulated windows equipped with double- or triple-pane glass have airspace between glass panels that reduce heat conduction between indoor and outdoor surfaces. If your windows have condensation within the airspace, then it indicates failed window seals, which means you need to have your windows repaired by your window contractor.
