Oh my sagging door

[ed morini]

If the door structure itself has been compromised you should see visible signs in the door itself. Usually openings in the joints at the intersection of the rail and stiles. If that's the case you might be able to re-glue the assembly back to square, but because of the door construction success is iffy.
If this is a metal door(you didn't say) the above mentioned replies should work.

get a new door and install right. Cry now but smile later.

or you can take an extra sharp chisel and chisel the top hinge mating surface
so you can suck it in some more

easy enough to make cereal box shims if need be

Yes, it's an older solid wood 9 light. Definitely has visible cracks and the reveal at the top shows the sag. I removed the top hinge shim and sunk a long screw into the frame which pulled it up enough so that it doesn't rub on the floor. But it does still rub on the metal threshold a bit. It closes but not well.

Is there any way to square it up without major surgery or should I just take a kerf off the bottom?
