Water Damage

A few weeks ago, a repairman (from Sears) came to my home to repair my washing machine. He forgot to put the hose back into the drain, which resulted in water pumping onto my floor for 2 hours. Although I removed the water immediately (with a shop vac) and put fans in place, my ceramic tiles started to crack (in the tile, not the grout). The cracks are present in my laundry room, kitchen and master bath. However, the tile runs continous throughout my dining room and foyer. The contractor has stated they cannot match the tile and grout. The insurance company has indicated they will only pay for tile replacement in the damaged rooms, in spite of the continuous nature of the tile. Is this correct, or are they obligate to replace the tile in all of the rooms?
