How to Disassemble Double Glazed French Door Glass

Remove the screws that hold the doorknob or handle in place, setting them aside carefully. Remove the rim of the doorknob and set it aside. Twist the different sides of the doorknob until they begin to move within the door. Pull the doorknob out of the hole in the door, separating it into parts as necessary and saving all of the pieces. Reassemble the doorknob into one piece, attaching all of the screws again so that the doorknob can easily be reused. Repeat for the doorknob on the other door.

Set the drill against the hinge attachment screws and loosen the screws that attach the hinge to the door and the frame. Repeat for all the hinges and lower the doors to the ground. Set the hinges and their attachment screws aside to be used in a future project.

Inspect the doors for any other sections that have been attached together with screws. Loosen these screws and disassemble the door as much as possible.

Slide a putty knife into the area between the trim boards around the glass and the glass surface itself. Pry up the trim boards little by little, using the utility knife if necessary to cut the seal of the paint that might be holding the trim boards to the door panels. Remove the trim boards entirely and pry up the glass panels in the same manner if possible.

Separate the remaining door sections any way possible if the glass is still surrounded by wood and cannot be removed yet. Cut seams held together with glue using the utility knife. Pry sections of the door apart using the putty knife and then a nail puller as the hole gets larger, wrapping the nail puller in cloth if necessary to protect the wood from damage.

Cut the wood sections of the door into pieces if all else fails in order to remove the glass from within the door, being very careful not to cut too close to the glass and possibly cause cracking or other damage.
