T
Time's Ran Out
Another day and it doesn't look any better!
If I understand correctly the dado and everything above it needs to come off. Below the dado is fine. I know I can't talk prices but can I discuss time? To take off (trying to save the dado), retiled correctly and re skim the walls to completion, how many day are we talking?
Just get a local tiler in to give you a proper written estimate to redo the whole job to our industry standard. Anything less and you are accepting shoddy workmanship and he will continue to ruin other projects.
