We have been wanting to replace a side door. everyone that we have talk to so far does not want to touch it. Problem is that the door opens and to the left of the door is a pocket door going to the basement. It is impossible to put in the new door frame of a new door. The current door frame is not square. We think the previous owner put the door there so that they could get to the basement from outside, without going thought the house. Does anyone have any suggesting on how to correct the problem and put in a new door?
