Foggy Window Glass Repair in Knoxville TN: When to Repair or Replace

What Foggy Glass Usually Means

When a window looks cloudy or milky between the panes, the problem is usually not dirt on the surface. It is a failed seal in the insulated glass unit, which lets moisture drift into the space between panes and leaves a haze that will not wipe away.
