I've got a heavy solid-core door with hinge problems. The original
screws have loosened up and stripped out. Several of these were
replaced by what appears to be 3 inch decking screws. Now it appears
that even these decking screws have loosened up and lost traction.

What's the best way to restore solid hinge attachment to the door
frame? These doors are very heavy......



How many hinges do you have? You should have at least three. I replaced my
cheap luan hollow doors with solid about 3 years ago, and added a middle
hinge in the process. They've been trouble-free.
