Hey there. Depends on the type of maintenance. The glass panels themselves don't require much at all. However we recommend the door, the springs, and the opener be service each year to make sure they keep giving you the best performance year after year. Otherwise the glass doesn't require any specific extra maintenance other than cleaning at your convenience and repair should one get broken like any other panel of a garage door. Hope that helps. Give us a call if you have any other questions. Thanks. OHD KC Team
