Robinson Tile

Tile contractor, Robinson Tile, was suppose to: 1) re-grout entryway tile. 2) prep living room floor by leveling the floor 3) install crack isolation membrane 4) Install tile, supplied by homeowner. (12 x 24 porcelain tiles-Daltile Marble Attache Carrera. Mr. Robinson took a $500 deposit, then claimed to be leveling the floor while tiling using cracking isolation membrane mortar. I first noticed a large gap between the bottom step from the kitchen into the living room. I asked Mr Robinson about the gap & he said he was going to grout the joint. I pointed out this was too large of a space to grout & he argued. Then I noticed a large amount of uneven tiles (known in the tile trade as lippage). Almost every tile has a corner higher than a nickel when laid flat. The edges of these rectified tiles are sharp, the edges will cut bare feet, & also be susceptible to chipping. the contractor did not use antillippage devices/towers to avoid this issue In the unfinished corners of the room I can see under the tile, large honey comb like spaces. I am able to stick my finger in the spaces. I researched the issue, this is known as "spot bonding". It's a violation of ANSI standards. The floor tile will not be able withstand heavyweight. Even a heel strike will cause breakage. Water from mopping can get trapped in these cavities. Additionally, the glue used in spot bonding is brittle & subject to breakage. The entry way was regrouted leaving gaps in the grout, & the former grout which is white shows through.
