Tom, you heard right. How much of the foundation is accessible? How much do you have time to test and are you able to? Termite, Carpenter ant damage and wood rot will not stand up to the ice pick test. This is not a prank. If that ice pick finds it's way to penetrate deep, Look Out, you've discovered a money pit.Also look good at all ends of the foundation in a perspective that allows you to perceive any sagging along the foundation line. As to being treated, unless it's .60 pressure (not .40 ) I'd think twice.
