Hanging a Heavy Door
I am having some solid core doors hung. Standard 1-3/8 6'8". I read with the heavier doors that a long screw should be placed in the top hinge (they way I remember it) so the jam doesn't sag and door doesn't warp.
Is that correct for this type of door? What size and type of screw? Does it need to go through a shim? Is it really necessary for a solid core door? Not sure they weigh as much as solid wood. The jam is prehung quality and there are some good size gaps between the jam and studs.
I was going to ask my carpenter to do this on the doors to be safe. He had actually done it but on only one of them. Not through a shim. I'm sure he used a coarse drywall screw. Is that ok?
I see some people do more than the one screw but it seems they were talking about very heavy doors.
What would you do and is what he has done sufficient? One coarse drywall screw top hinge no shim. If you'd change something, how important is it? I don't want to bug him if it's not critical.
