Installation: August 2007 Very disappointed, prep was not done properly and many tiles were uneven. He had a kid helping him that appeared to be just learning. He came back and replaced about eight tiles. Finally we had a grout guy come out and take care of the cracking grout. Still have one tile that makes a noise when you step on the corner. Update: the tile that made a noise when you step on it no longer makes a noise because it has three cracks. Evidently there is a hollow space under the tile.
