I was asked to coordinate a remodel for a client who owns a Pulte home; in a VA neighborhood of Pulte homes!
I was shocked: all the tile was installed directly on the plywood sub-floor rather than using Durock or Hardy board; the "industry standard." Curious; the owner and I decided to poll the neighborhood: all of the responses have been the same: cracked, chipped tile - tile to sub-floor; no intermediate material!
Siding problems too! One owner was told if he remained "quiet," it would be repaired in its' entirety.
Owner's biggest investment = their house.
How dare Pulte!
