The front door of my 90 yr old house sticks out at the top corner by 1/2 inch. After studying the problem and reading for the past few weeks I have come to understand the frame was twisted to fit the outward sloping wall 30 yrs ago. I do not use the door but would like to fix it before putting the house on the market. Kids are gone and I am downsizing. Cash is tight. I just want it to look decent. Any ideas would be appreciated.
