Should I call Guardian Glass if I need help with my window or door?
If you have a window or sliding glass door that needs parts, repair or replacement and it has a “Guardian” stamp on the glass, the stamp simply means the glass was “tempered” by Guardian to make it stronger. We did not make the window or door.
Guardian does not manufacture windows or doors – we make glass for window/door manufacturers who use the glass in their products. Warranty, repair, parts and replacement issues for windows and doors should be directed to the window/door manufacturer. The manufacturer may be identified on the crank, latch, other hardware or on the spacer material between the two pieces of glass if it is an insulating glass unit. If there are no identifying marks on the window and you know the company/builder of your house they may be able to help.
