Want to run this by the crew. I have a client that removed a wall between two rooms. They had an engineered LVL installed in the attic crawl so that the finished ceiling in the room below was flush across. They have had a constant crack at the drywall seam that they have already repaired twice since new and I think I know why it keeps re-appearing. The ceiling joist run in opposite directions on either side of the LVL. Those perpendicular are attached to the LVL with joist hangers. Rather than breaking the drywall to split on the double LVL, they made the drywall seam at the edge if the LVL and under the joist hangers. See sketch - I think if they cut back the drywall and split the seam on the LVL and moved the patch seam 2 feet into the perpendicular joists that will eliminate the constant crack. Thoughts? Roof is stick build ranch style so no trusses involved. [ATTACH]70874[/ATTACH]

Hi Everyone, So I just gutted my 10'x15' living room and wanted to get opinions on drywall. I've heard many different things such as 1/2" for walls and ceilings, 5/8" for both, or 5/8" ceilings&1/2" walls. What is the proper type of drywall? Do I need to use mold resistance? Thanks, Sam
