OP, as a contractor, I would not like that you hired me to do a job and then went onto a random Internet forum to verify the quality of my work or choice of materials. If you came to me (the professional) and told me that a faceless, nameless internet somebody said that I was doing it wrong and suggested a better way of doing it, I'd walk off the job. The nature of questions you're asking suggests that you don't know anything about the work taking place, so be mindful of that when you offer advice to your contractor. There's an old saying...if you can't dazzle them with your brilliance, then baffle them with your BS. It would in your best interest to let the contractor do their job without telling them how it should be done...in this case.
With that attitude, you definitely would be leaving!
