Entry door needs to be repaired

[Joseph Venne]

Hello all,

As I have already said, I am planning to rent my old home. Yesterday I went there to check whether it needs any upgradation. I found that the entry door is slightly jammed. It is a bit difficult to open and close the door. First, I thought that I'll have to call a  replacement windows and door service. But while searching online I found few articles giving guidelines to repair a jammed door. I understood the steps, but I don't have any first hand experience in repairing a door. If I do it by myself, I'll be able to save the repairing cost, but I'm not sure whether the work will be perfect if I do. What shall I do now?? Does anyone here have any experience repairing the door?? Any suggestions??
