Has anyone seen 3/4" OSB floor sheeting installed where the joints are not staggered? 20x24 room addition with the 4x8 ends butted to each other. In my 30 years of inspection and construction I have never seen this done before? Homeowner mistake. It's glued and will have concrete board and tile floor added at the finish stage. Would you request this be tore out and redone or do you think that concrete board placed and staggered over the seams will suffice?
