A few months ago I posted to this group about my tile showing an indentation
directly on top where the subfloor meets. I also explained how one of the
tiles cracked, the installer replaced them, but then the indentation came
back and now 5 of the tiles have cracked. Based on various responses from
this group, I contacted the Attorney General since the installer was blaming
it on a structual issue. The installer still claims this and refuses to do
anything else. It appears to me that he did not ensure the subfloor was
properly secured to the joists and that should be his problem.

I would like to know if anyone has some good suggestions to go back to the
Attorney General and installer with.

My original message posted some time ago was:

I had a new home built in August 2000 and about a year later noticed that
one of the tiles was cracked down the middle. This had me look at all the
tiles and noticed that an indentation was going down the center of numerous
tiles...happens to be right above where the floor boards meet.

The builder had the tile guy replace the cracked tile, which caused the next
tile in line to crack. However, they waited until May 2002 and the replaced
tile did not crack again...at that time they removed all the tile that
showed an indentation and the associated wonder board. It was replaced with
new wonder board (just the portion below each 12 X 12 tile (usually in a
line of tiles), tile, and grout.

Well, sadly, it is now showing the indentation on every tile that was
replaced.

The tile guy claims he has never seen this before and does not know what to
do. I looked at another house he worked on and it too has the same issue.

I watched him do the job and it appeared to be a good one, but I am not a
tile expert.

I need some ideas on what could be wrong and what I should do.

Any experts out there?
