Reply to comment by jrab3717 in Had a plumbing issue upstairs, now i need to replace a ceiling drywall cutout used to access the plumbing from below. My progress is below, and im now nervous about the consequences of adding the joint compound without an actual joist or wood anchor behind it. Is this patch temporary or should i be by jrab3717

Take out the drywall, cut some squares of plywood and fit one to each corner of the hole so it bridges between the new and old drywall. Screw it down to the old drywall, then fit the new piece and screw it in too

The old drywall crumbled las time a drill touched it, which is why I am a little nervous affixing anything to it.

I don't really see that you have a choice. The patch as-is doesn't have enough support, you either need to support it or replace more of the old drywall until you get back to studs

Dude needs to cut back to sold drywall, otherwise the repair will be crazy obvious.
