How to remove sliding glass door frame
The sliding glass door panels have been removed and the door frame is left. It would seem removing it would be easier than the door panels, but the job takes time and thought.
Allow at least two hours from start to finish.
Prepare for frame removal
Some frames can be imbedded into the house, meaning exterior trim may need to be removed.
Some frames may have exterior and interior trim. Both must be removed before attempting to remove the frame.
First use a pry bar to remove trim on both sides of frame, indoors (if needed) and outdoors. Removing top trim pieces may also be required.
Remove the nails and set aside as you will put them back into place later.
Prevent damage to walls
Interior and exterior walls can easily become damaged. Using a flat board while prying can eliminate unnecessary repairs later. Pry against the board and not against the house. Gouging and even holes can be created, if care is not given to the process.
Pull nails out with a hammer claw.
Pry frame loose
Once the trim has been removed, the next step is to cut the outside edges of the door frame with a metal saw. Cutting the nails holding the frame in place is the key to loosening it for easy removal.
Using protective glasses, place a chisel between the frame and the stud to form a gap big enough for the metal blade to fit. Turn on the saw and carefully cut through the nails.
Ease the frame out
Pull and ease the frame away from the house a bit at a time. If the frame sticks, tap it out with a hammer being careful not to ruin the supporting structure.
