Hi everyone, I'm planning on putting a new OSB floorboards on top of my existing floor (please don't judge me on this ) and then laminate flooring. I've watched a dozens of YT videos and in all of them they say you should undercut door frame to nicely fit laminate underneath. But check my pictures, am I really supposed to cut out the whole bottom piece of my jambs? It's pretty thick, plus metal detector says that there is probably a screw or nail in there. Will this have no effect on how the whole frame holds up? Any advice welcome!
