What Window Condensation Usually Means
Light condensation on the interior side of a window is not unusual in Rockville, particularly when humid outdoor air and cooler glass surfaces collide.
That said, not every fogged window means the same thing.
Interior condensation usually points to excess indoor humidity, weak airflow, or a cold window surface that drops below the dew point.
When the fog is trapped between panes, that is a different story.

How Homeowners Can Limit Moisture Buildup
