I was at a relatives home this weekend. Before I went into business I renovated there kitchen as a practice job so to say. The kitchen has a second floor above half of it and an empty attic space above it. I noticed that in the part of the kitchen where the attic is above, a space has developed between the crown the drywall on the ceiling. All miters and copes are still tight, and crown is still tight to the walls and cabinets. I also installed cleates before installing crown. All crown is 2" oak; space is close to 1/8" in some places. Any ideas where I went wrong?

If the roof framing is trusses and you live in a cold climate, the ceiling may be lifting. It is common. The cold shrinks the webs enough to lift the bottom chord. Wait till spring/summer and see if it drops back. If it does, that's your answer.

That was my first thought, but the framing is either 2x6's or 2x8's I don't remember. Do you think this could still be the case?

It's likely truss uplift, caused by dryness, not temp. The dryness is caused by the cold temp, if that makes sense.

I get homeowners calling me all the time for this. If you can caulk, caulk it while the gap is exposed and when it retracts, which hopefully it will, you won't have anymore visible cracks. Allow a season of cold and hot to pass to see if that corrects the problem.

God bless.

Thats just the weather,but one thing that might help is to shoot finish nails upwards in the ceiling so that they cross each other and it helps alot. When u cross them in the sheetrock it acts kind of like a hook and wont pull out,then run a small bead of pheanoseal
