I recently moved into an apartment where the front door is leaning because the top hinge is broken. I have never come across this before but it appears that the door is attached to a metal frame that the hinges apparently have been pre-welded into the frame, as there are no screws or anything for me to remove the hinge from the frame side, I'm assuming as a security measure. The apartment complex was built in the 60's which I believe is how old the frame/door is. Is there any possible way this hinge could be repaired/replaced by doing it myself aside from cutting and welding a new hinge on? What type of repairman should I call for professional work, all of my searches are generally coming up for garage door repairs? Or will I just have to get the landlord to replace the entire frame? Which would be my last resort. Thank you in advance for the replies.
