I asked this question in the other (FixIt) forum as well. Got one reply there, suggesting that the problem might be truss lift. Don't think that applies in my case - two story house, with joists over the room in question. I might add that the cracks are *not* large - maybe 1/16" or a bit more, and easily filled with caulk. I'm just wondering if I'm on the right track thinking it's a minor, temperature related problem...
Put up crown molding in dining room last August. Looked great then, still looks great. But just noticed that if you look closely, small cracks have opened up in a few places between ceiling and molding. Almost all on exterior wall, so I assume temp change (cold weather) has something to do with it. No problems on interior walls. I can caulk and repaint, no problem, but I hate to think that I'll have to do this regularly... Am I correct in thinking that this is a one-time, temp-related problem? House is 10 yrs old, so I don't think there are any settling issues.
