My broter is a home inspector in the suburbs north-west of Dallas and he can tell some horror stories. The builders HATE HIS GUTS as do the real estate agents. His clients LOVE him. he does no advertising, all of his business is repeat and word of mouth and he cannot keep up. Anyone who is having a house built without his own inspector doing the periodic inspections is crazy.
I'd give 100 likes if I could. All my work was commercial/industrial/institutional. Idiots install the stuff (especially when I worked for the Pgh School Board) then you never see them again. I didn't appreciate fixing some hack's mess-ups. (I usually spell MESS differently.) Yes, if I were to have a home built the contractors would hate me. One mechanical contractor I worked for had our own guys hating me. I loved that! Stupid idiots running heating & cooling water piping right in front of the control panel & filter access doors to make them inaccessible was done often. I just refused to "sign off" on certain things. It wasn't my money, but I was going to be the schmuck working on the stuff.
But a person's home, that's completely unacceptable. Good luck X 100!!
