Eric stated: "In fact, when I do re-inspections, rarely was all the work done correctly."

I would remove the word (from my experiences) "correctly". Hell, it is rare that all the work was done! More than 50% of the time the lists will include items that haven't been touched/ repaired but were on the repair list.

I've been told... "Well, when the HVAC guy got there, he said the trap vent didn't need to be past the trap. So he didn't do anything"

My reply-- "It no longer matters what he thinks... the contract ammendment (signed by the seller) stated that repairs will be made to that item".

That's just one of the fights that goes on and on.
