What Usually Causes Window Condensation?

Read on to learn why window condensation happens.

Why Does Window Condensation Occur?

Condensation forms on windows when warm, moist air comes into contact with the colder glass surface. It often occurs during the colder months but can happen whenever warm air’s water vapor comes across cold surfaces. You don’t usually need to worry about condensation on your windows as long as they eventually disappear. It’s also a sign that the units have tight seals and are energy-efficient.

What Causes Windows to Fog Up?

High Indoor Humidity Levels

Cooking, showering and drying clothes indoors can significantly increase indoor humidity. These activities can heighten the likelihood of window condensation. You can eliminate excess humid air from your living space by improving ventilation and running dehumidifiers.

Window Seal Failure

Your windows likely have compromised seals if you can’t wipe the condensation on their surface. It means they are no longer providing insulation. Since seals are not repairable, you need to replace the affected units.

Aging Windows

Deteriorating or aging windows are usually less effective at insulating your home. It can result in substantial differences in temperature on either side of the glass, encouraging condensation.
