Why is there fog or moisture between my window panes?
Moisture trapped between panes commonly points to a failed seal in an insulated-glass unit. Surface condensation can have other causes, so identifying where the moisture appears is an important first step.
Does a fogged window always require a full new window?
Not necessarily. If the frame and operating parts remain suitable, replacing the insulated-glass unit may address the glass condition. The opening should be reviewed before the scope is chosen.
Can I describe the problem without knowing the technical term?
Yes. Tell Banks Inc. what you see and where it appears. Photos and a simple description are enough to begin.
