Fogged-up windows often cause concern for homeowners. In some cases, condensation on windows is nothing to worry about, but in other instances, it indicates that there is a serious problem. It’s important to understand what condensation on windows means and what you should do about it.

What Causes Window Condensation?

Condensation forms when humid air comes into contact with a cold surface and water droplets collect on that surface. You need to know where condensation is forming because that will help you identify the reason and figure out whether you need to take action to address it.

Does Window Condensation Mean That You Should Be Concerned?

When condensation forms on the inside of windows, it’s because the glass is cool and the air inside the house is warm and humid. This typically happens in the winter. High levels of humidity and condensation on windows inside your house can lead to mold and rotted wood. You can reduce the indoor humidity level and prevent condensation by running a dehumidifier, using exhaust fans in the bathroom and kitchen, and opening doors and/or windows to promote air circulation.

Condensation forms on the outside of windows when the air outside is warm and humid and the surface of the glass is cool. This generally happens in the summer when outdoor humidity is high, the wind is light, and the sky is clear at night. If condensation forms on the outside of your windows, it’s not something you need to be concerned about.

If condensation is forming between the panes of glass on your windows, that’s a problem that needs to be addressed. It means that the seal has failed and moisture can get into the space between the glass panes. Your windows probably need to be replaced.
