The grout in the tile has cracked or separated all the way across the house from one side to the other. I figured it was normal due to settling. In the kitchen it has become really bad, to the point the tiles are cracking and there is approximately a 1/4in difference in height. I decided to replace the cracked tiles and discovered a large gap in the floor real close to 1/2in wide.
Should I worry about this or should I just replace the tiles and let it go. The house is 7 years old.
