Hi,
I have UPVC French doors on the back of my house, recently the lock mechanism jammed in the lock position and I had to have an emergency locksmith come out to open it. This was through insurance via my bank so was a temporary fix where be completely remove the bottom half of the lock and put temporary locks on the door.
I was just wondering how much it costs to replace the whole mechanism or if it is worth completely replacing the doors (as the emergency man suggested). They are basic UPVC doors that you find in B&Q etc.
