I recently had a fire in my home and I am having the kitchen redone and the ceiling in my living room replace. The contractor that I hired put the dry wall up in the living room and in the kitchen without putting in installation. I asked him and he said that he was going to take down one piece of the dry wall and blow the installation in. So I said okay. But then this morning he sent a crew in to tape and mud the drywall. No he said he is going to go through the attic and blow the installation in. Should I be concerned about this contractor?
