Thank you to all who replied. To answer the one question, I hired a
local handyman (there's a connection to the family), so for various
reasons I'm moving on. Probably would have been better to hire a
professional contractor, I know.
I thought it would easier if I posted a detailed photo, worth a
thousand words. Unfortunately, I do not have any photos of the
cracked grout since I already started removing the tile (long story).
