I am about to put drywall up in my basement. The ceiling is just under 8 ' so i am running horizontal around the room on the walls. I have one wall that is around 30' wide. My question is do i have to stagger the panels on the wall. Is it really necessary for strength or can i just stack them so the butt joints run from ceiling to floor. There so many different opinions, I would prefer not to stagger as i am having a professional taper do the seams. Thanks, any additional advise would be great or photos of your layout prior to mud and taping.
