Step-by-Step Guide to Replacing a Broken Door Glass Pane

For doors where the glass is held in by wood or metal stops (instead of being a sealed IGU), the following process is typically followed by restoration specialists.

The glazing beads or putty are carefully cracked away using a putty knife. If the old putty is stubborn, a heat weapon is used to soften it, making sure not to swelter the door frame.

Once the glass is removed, the remaining debris, old points, and dried putty must be scraped out of the “rabbet” (the groove where the glass sits). The wood or metal is then cleaned down with denatured alcohol to make sure a clean surface for the new sealant.
