I have a contrete slab floor and want to put a new subfloor over it but would need to remove the sliding glass door and then reinstall on the raised floor. Do I just put the threshold on the new subfloor and can I cut into the header to accomadate the new height? It's a 6' door and I want to move it up 4". Thanks.
