4 Things You Should Know About Fog On Your Windows

Fog or condensation on your home’s windows can be a nuisance, and in some cases, damaging to your home. Often the reasons for this problem are harmless and can be easily resolved. But in others, it could be a sign your windows need to be replaced. Here are four things you should know about the fog which might be appearing on your windows.

Why do windows fog?

The reason windows fog is the same reason fog happens outdoors. Warm, moist air comes into contact with much cooler air. This causes the moisture you cannot see in the warm air to transform into a mist (fog) or water droplets.

With today’s homes and windows becoming more energy-efficient and airtight, if you have fog or condensation on the interior side of your windows, it is likely because the air outside is cold and the inside of your home is warm and humid. Once the outside air warms up, the condensation should dissipate. When the fog is on the exterior of the window, it is likely warmer outside than it is in your home.

When is window fogging okay and when is it not?

It is normal for windows to fog up at the beginning of the heating season as any humidity which may have built up inside your home begins to evaporate. However, the amount of condensation should only be minor and only occur when there is an extreme difference in temperatures between indoor and outdoor spaces, especially if the humidity level is elevated from steam from a hot shower or cooking.

It is not okay if fog or condensation occurs in between the panes of glass in insulated windows. This means the window’s airtight seal has been broken, the gas between the panes has escaped, or the desiccant in between the panes is saturated with water.

How can bad causes of fog be fixed?

Most instances of foggy windows can be resolved by simply opening the window for a few minutes until the fog dissipates. This solution is similar to how you would open a car window to clear the fog from the inside of a windshield.

If you have a fog and condensation problem with your insulated windows, you will need to have the glass replaced. And if you have older windows, you will likely need to replace the entire window.

Why should you work with a window expert?

When excessive moisture exists in your home and continually causes fog and condensation, this can cause water damage and mold in your home. If there is no obvious reason why your windows are fogging up or if your insulated windows are fogging up, you should work with a window expert to determine the cause and whether a repair or replacement is needed.
