I have to lift a door by the handle to get it to latch and want to fix this . My initial idea was to remove the strike plate, chisel out another 1/8" at the bottom edge, fill the existing holes, drill lower holes, then re-att ach the plate. But since the new holes are going to be so close to the fil led holes, I suspect the filler won't hold up.
I wonder if it wouldn't be better to simply grind down the bottom of the st rike plate opening with a Dremel and keep using the original holes.
