I’m asked by Farmer’s Ins Co to make an inspection of a ceramic tile installation from a year ago. This floor is a replacement for a hardwood floor flooded by a clothes washer whose water shutoff/fill level switch failed. They only removed the hardwood and three weeks later began a three week installation of the tile. Underlayment is the 1/4 inch concrete type, nailed not screwed.
I’ve only put in three such floors in my life, first with a master mason/tile person, and, therefore, am not an “expert.” I believe I know the basics on how it’s supposed to be done.
My question: what is the “professional” way to check for voids, proper mortar, proper underlayment, properly attached to the floor, etc.
