I doubt if they have in house plastering, I bet they sub it out. The only two or three do their own in Tucson. I learned alot in the last 6 months about how it all works, at least here in Tucson. It all started 50 or so years ago and one family, I forget the name, did most if not all of plastering in town. Over the years they have had their own families and alot of them continue to plaster. So what I understand they are all pretty much related. I had the guys from Stewarts and they did an amazing job. If I had to do it again I would pick Meadows,Pro plaster or Stewarts or Luis Rodriguez with Rodriguez plaster. They seem to be related and all know each other so it really doesn't seem like it matters much who does it. Good luck, looks great so far.
