How to Prevent Condensation on Your Windows

when there’s a major difference in temperature indoors versus outdoors. When it’s on the outside, condensation is essentially dew, and disappears when the sun warms the window. Indoor condensation, however, is a sign of high humidity in a room—or possibly the entire home.

But window condensation doesn’t just block your view: If it occurs regularly, over time, it can cause damage. Here’s what you can do to forming on your windows in the first place.

What causes condensation on windows

It’s not unusual for condensation to form on indoor windows, This can happen when someone is cooking (especially boiling water), taking a hot shower or bath, or drying clothes. In situations like these, the condensation typically goes away when the indoor humidity level returns to normal.

However, if condensation is forming on windows throughout the house, even when humidity-increasing activities aren’t taking place, it’s likely a sign of excessive moisture in the home—a wider problem that should be addressed right away.
