My wife and I bought our home 3 years ago. It is roughly 50 years old, and had recently been shored prior to our purchasing it. There were a few cracks in drywall here and there, nothing that wasn't easily patched and painted. Six months ago, we had spray foam insulation installed in our attic, and since that time, I've noticed some cracks starting to appear once again, some in places I'd previously patched, some new. As I was inspecting a re-opened crack, I looked around the rest of the house, and found an interior wall where the seam where the all meets the ceiling has split, almost the whole way across the room. I'm wondering, what could cause that? Could it be related to the weight difference caused by the newly installed insulation in the attic? Could it be some natural settlement following the recent shoring job? We also had a drought for most of October through present, which could also cause some settlement issues. I have visually inspected the slab, but I don't see where any significant cracks have appeared. Has anyone seen anything like that before, or had a similar experience?

Best Answer
You indicate that you have been in a drought since October. Combine cooler weather, better insulated roof, and heat being on; the structural framing of the house may have shrunk.
I experience some "seasonal" cracking and shrinkage in my home. See what it looks like in July/August, if the condition persists, consult a local experienced contractor.
