Broken Window Seal: Repair or Replace?

When the seal around an insulated glass unit fails, the appearance can become cloudy or streaked and the sealed airspace no longer performs as intended.

What can be replaced

In some designs, a glass company can replace the insulated glass unit without replacing the entire frame. Availability depends on the window construction and condition.

When full replacement is worth comparing

If the sash, frame, weatherstripping, hardware or surrounding installation is also failing, replacing only the glass may solve too little of the overall problem.

Compare total project value

Ask what each option fixes, what remains old, expected appearance, warranty coverage from the provider or manufacturer, and how the cost compares.
