A different flavor of this (in home re-modeling, hardscape etc.), is that the people who come to do the estimate are different than the people who come do the job. They are typically younger and pretty much clueless as to how the work would have to be done. So you can't ask them any detailed questions. All they can do is run the spreadsheet on their laptop and show you pictures of other work their company has done. They were trained on how to make a sale, that's it. Had to go with someone who I had a little trouble communicating with, but at least I could verify he knew what they were doing and understood my concerns about how the work got done.
