I live in Seattle and it's currently wintertime. The house was built in 2014, we purchased this house in 2018 and did not have any nail pops or drywall cracks back then but the house was freshly painted so they probably just covered up a bunch of nail pops and cracks.
When it started getting cold this fall, I noticed a few nail pops in the ceiling on the 2nd floor of the house. A little later I got a crack along the edge of the ceiling and what appears to be drywall tape peeling in a couple of places.
I've checked the attic and there is no sign of water damage in these spots. There is some water near the edges of the foundation in the crawlspace that we are having addressed this spring by installing a french drain via a foundation repair contractor.
What's the best way to repair the peeling tape along the edge?
Is there anything out there that's better for edges than just applying more drywall tape?
