Window Warranty and Repair — Important Information

If you are a homeowner needing a window repair or replacement, and you have a Vitro (PPG) glass logo in the corner of your residential window or door, it means that Vitro glass supplied that specific glass component to the manufacturer of the window or door. Our warranties are offered to the manufacturer who produced your window or door. If you have a claim or are in need of repair for a window, door or insulating glass unit, please contact your original manufacturer.
