My dad is a home inspector, and a few months ago we purchased a 2 story house in arizona. Something is terribly wrong however, because the whole house has huge cracks now. Up the walls, on the floor, we recently peeled back the carpet and to our horror found a 2 inch crack on the floor going all the way through the tile, pieces of tile are falling off and cracking, the windows are cracking. I need to know why this is happening..I think the concrete foundation wasnt right.. and we were never informed of this problem. Please help!
