How to Check for Window Condensation

A lot of window condensation is something, as a homeowner, that you want to avoid. Condensation occurs on windows when hot air comes into contact with dry cooler air. You will have condensation on interior windows when there is an excess of moisture in the home, and that warm air comes into contact with the cold windows. Exterior condensation occurs when your Milgard window is colder than the dew point outside, and the dew accumulates on the window. Whether it be exterior condensation or interior condensation, it is critical that you be able to remove condensation from your window, and, therefore, you should check for condensation on your Milgard windows regularly. This guide tells you how to check for window condensation. (Please make sure to read our FAQs disclaimer before reviewing or enacting any FAQ content/recommendations.)

The proper materials required to check for window condensation is a soft cloth, glass cleaner, and, as always, gloves and safety glasses.

First, we will start with checking for condensation on the interior window. Take your soft cloth and thoroughly spray down the interior window. Then wipe the interior glass with your soft cloth. You should see the condensation disappearing. If it is not disappearing, then the condensation could be on the windows exterior glass.

Therefore, move on to the exterior glass, and, once again, take your glass cleaner and completely spay down the outer window. Then, wipe the surface glass with your soft cloth. Hopefully, now, the condensation will disappear. If the condensation does not go, you will have to contact Milgard and set up an “insulated glass unit” replacement.

Repeat these steps for all your Milgard windows to check for and remove window condensation.
