Reno:
Good contractors are definetly considered an allie (sp) IMHO, as an inspector.
Notice the word 'Good'.
Definition of 'Good' is paperwork, performance & conformance, job supervision as required, and follow-thru to 'final'.
As an EC, a good inspector was also considered an allie (sp).
As to my clients, I have to say I considered myself lucky that they, for the most part were, really great people. We respected each other and had mutual trust. Them for getting what they wanted, when they wanted it, and me and my employees for a good 25 years.
LOL at the 'cost so much'...when have you called a plumber lately?
