Well, as far as my office goes it changes with every home I do.  when discussing an estimate with my clients, I'm always sure to let them know my involvement during the project at hand.  I am always there on the opening day of the project throughout and the day we close finish.      I send my clients updates via CompanyCam more often time than not to make sure they stay as updated as possible throughout the project. This way, there's no surprises. Information and communication is key.
