I have a broken window pane in my front door. I need some advice on how to replace it. How do I measure for size of replacement glass? Is there any particular type of caulk that I use once the pane is in place?

It depends upon the frame material and how the glass is held in place.

If the frame is wood the glass may be held in place with a removable wood trim. This trim must be VERY carefuly removed so not to cause damage. Cut around the joint between the trim and the mullion with a razor blade or matte knife. Then gently pry the trim away. Note that the corners are usually mitered. You should find that there are very few nails holding it in place. Don't replace it with any more nails than it already has. The glass should then come out unless glazing caulk was used. If so, cut it away with the matte knife. The replacement glass size should be the highth and width of the recess less 1/8". If you give the glass company the size of the opening they can size the glass accordingly. Reverse the process to reassemble, putty the holes, and paint.

If the glass is held in place with caulk, scrape away the caulk with a hooked blade deglazing knife or other tool of your choice. Be careful not to cut the wood. After the caulk is removed remove the diamond shaped glazing points that are stuck into the wood. Remove the glass get a install the new. Sizing is the same as above. Reset the glass with new metal points (handyman versions are available that are easier to use with a common screwdriver) and add glazing putty with a putty knife. Striking a flat surface on the putty is a skill not achieved on the first try. Let the putty dry for a week before painting.

If the door is metal, the glass is held in with a snap-in or screw applied trim. Remove the snap-in by popping off the trim with a prying tool or screwdriver. Size as above and set in glazing putty to seal gaps. reassemble the trim.
