My husband and I are replacing an old door. We have a 100 year old house with unique door trim, so we didn't buy pre-hung doors. We bought new solid doors and chiseled out the new door ourselves. The new door also require 3 hinges while the old door only needed 2, so we had to chisel a new middle hinge area on the door frame. The problem is, when we screw the door up, it doesn't shut all the way because it's hitting hinge side. We tried using shims under the door hinges, but so far that hasn't really worked. The hinges are flush on the door, so I'm not sure why this is happening. Any suggestions?
