This is the granite at the entrance of my place:
As you can see, a huge crack has developed over the past few years. House was built in 2002 and I moved in in 2005 and I'm confident it wasn't there at first. The crack extends into the granite that's in the closet to the left of this pic.
There's a wall to the right of this entrance area, and you'll notice that the floor is separating from the wall/baseboard:
Is this a clear sign of a shifting foundation? I will need to do more than just replace the granite, and it's not gonna be cheap, right?
