We added some framing and put a piece of sheetrock to make a "pillar" between 2 open doorways a little bigger.
Of course, I did not consider that the drywall seam was placed where 2 separate parts of the wall structure meet, and so it is of course prone to cracking there.
The picture shows the area that we added drywall to, and the top of that is what it cracks (this is where the seam is, and where the beam for the opening meets the added framing). The crack is along both the horizontal and vertical edge along the top of the new sheet.
What can I do:
- to fix the crack now?
- prevent it from happening again? I know I could remove what I added + some above in order so that the problem area is spanned by a solid sheet, not a seam, but I would like to avoid this if possible).
