How to replace the glass from a window in a door

1. There is a finished side and a non-finished side to the window. Non-finished meaning there are wooden pieces holding the glass in on that side. (Usually the unfinished side is on the outside) Pull out the wooden supports on the unfinished side THEN measure the size of the pane glass that needs to be replaced!

2. When removing the broken plane, first tape the broken glass pane so when you take it out none of the pieces fall out and shatter. There is no need to make a bigger mess.
