Floor cracking, settling crack? Ive seen hundreds of 100 year old
houses with no cracks in shower floors, thats a hack crack, a poor job
done somewhere. You don`t need an atty just be sure your warranty time
is inforce, get a few bids and go file in small claim, when does the
warranty expire, got any photos. Is tile still smooth, enamel is still
on,, did you try a razor blade.
