Foggy Window Glass Replacement in McLean VA: Repair or Replace?

Why Windows Turn Foggy In The First Place

When window glass looks cloudy between the panes, the problem is usually not dirt, hard water, or a cleaning issue.

In a sealed double-pane or triple-pane window, the space between the panes is supposed to stay dry and filled with insulating gas or air.

That distinction matters because fog on the inside surface of the room is a different issue from fog between panes.

An experienced window replacement company can confirm the cause with a quick inspection.

How To Decide Between Glass Repair And Full Window Replacement
