I’m looking to reinforce a pre-hung interior door rather than purchase a solid-core replacement. The door was about 7/16” wider than the opening, so I cut the jamb down and then trimmed the hinge side of the door since the other side is bored for the door knob. Cheap being cheap, there’s only about 3/16” of “meat” left after routing the hinge and not enough to secure the hinge screw. Any ideas of adding some reinforcement inside the door where the hinge screws will penetrate? I was thinking about opening up a 1/2” hole behind the hinge and blowing in expanding foam. Not sure a screw will bind to it, but then again, maybe I can pre-install some anchors first. Epoxy?

Take off the whole edge and glue in a new thicker one. You’d be at nothing with the foam.

ditto on renners ^. Except for the winklepickers, since I don’t know what they are, or how they affect trustworthiness.

What renners wrote is what I was going to advise.

Or.. if it’s one of those white pressed doors it’s probably $29 at home depot. You could cut a little off each side then.

avxflyer, in the door business; we call this reblocking. clamp two 1×4’s on either side of door face, use your router with a template guide, and a straight bit. route out all waste don’t get into skin more than a hair. cut a new piece of fir or pine probably 1-1/8” wide and glue back in; reroute for the hinges, and your good to go!

Have your say...
