Re: sheet rock cracks
Seams from wall board is definatlely one possibilty.
Windows and door openings are more prone to stress cracks from movement.
Regardless, if there are or are no seams , something is moving to cause cracking.
Does it mean foundation issues? Hard to say over the internet.
There's no mention as to how old the home is or the construction type and whether or not this is drywall or plaster.. A new home will have lumber shrinkage which can cause cracks. Also a new home will undergo *settling* which causes stress cracks.
An older home , in most cases , will have done it's settling but structural deficiencies can cause movement.
