I have to replace an internal door in a house that has subsided. Unfortunately the jamb on the hinge side is not vertical and the hole is wider at the bottom than at the top by about 0.75". The lock side jamb is vertical enough. Are there any special techniques for this situation? Would I be better adding a wedge-shaped fillet to the hinge-side jamb? Reversing the door is not an option.
Thanks in anticipation
