we bought a forclosed house last year and for some reason in the ceilings all the joints are cracking and some have some chunks coming out. I was told its because it sat empty in the winter for at least two years and now with the heat and all everything is changing. Whats the best way to fix this so I dont have to do this again later? it has textured ceilings also so that makes it fun. Thanks!! I dont have anyone else to ask and figured someone here would have a good idea.
