Garage ceiling breaking open at dry wall seams: how to repair?
I am trying to make my garage (in central Texas) semi-comfortable to work in this summer. Right now the unfathomably hot 140+ degree air from the attic is just cooking it- in part because there is no insulation above the garage, but also because the ceiling dry wall seams are breaking open with very large gaps allll along some central seams.
I am a renter! We are not having great luck with property management doing legit repairs or taking an interest in problems they feel like we can survive with.
Before they offer a “solution”: I’m hoping to understand the ideal fix.
What (I think) I’ve gathered from some light research is that the dry wall should have been aligned with the 2x4s in the attic and nailed to them all along the seams? But these dry wall seams run perpendicular to the attic 2x4s.
(Even though I don’t own this house, I want to be a good steward of this property; and I don’t mind investing in solutions that will make life better while here)
Edit: I am planning on adding insulation to the attic. I have already insulated the garage door, and added new and additional weatherstripping. I do have an ac unit installed and ready to go. I just want to make sure the ceiling is properly repaired before laying down insulation.
