Re: Are my cabinets going to fall?
If you are certain that your fasteners (new and old ) are in the studs, then short of the cabinet falling apart, it's not going to come off the wall.
Are you noticing cracks between the wall/ceiling joints that expand and contract with seasonal temperature and humidity changes? If so, then you may have a condition known as truss uplift. If you've been experiencing unusually dry or wet conditions the house itself could be moving (normal in most circumstances), which could account for the cabinets seemingly moving. If this last condition is a possibility, you're going to notice changes in door clearances between the door and jamb.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
