If the windows and doors are in solid condition glass replacement might make sense. If you have a cheap Menards door the glass might cost more than a new door of similar quality.

+1 to Todd's feedback. Really depends on their condition and ease of serviceability.

The windows are Pozzi and still in good condition (other than the seals!). I am guessing that the door is Peachtree because that is what the other doors in the house were. Because the door sizes have changed, the price to replace all the glass is way under what a new custom sized door would be.

We have replaced all the other doors in the house and had to have custom doors made. We replaced 2 of them because of issues with replacing locks and handles. The other doors were replaced because they were sliders/french doors that were just not holding up well. This door is seldom used in a walk out basement and still works fine.

Replace the glass. Can all be done & over with in an afternoon. Less expense, less waste, less clean-up, less time.
