I do the same as Blaine. 2 hour appointments, tuning, pitch adjustment as necessary, repairs, and any left over time goes to improving the regulation and voicing as necessary and reasonable. I think I only have one piano in my database that truly only needed a tuning and nothing else, so being done extraordinarily early really isn't an issue for me.For new clients, I ask them to check a box on Gazelle that says "I'm a new client" which adds half an hour to their appointment. Sometimes I don't need it, but it's always better to be safe than sorry. This helps keep me on track with the rest of the day's appointments.
I usually start trying to wrap it up around the one hour forty-five minute mark. Fifteen minutes is plenty of time to put things away, reassemble the piano, accept the check, schedule additional work or the next appointment, and say goodbye to the client.
I've been doing it this way long enough that I am usually really close to knowing exactly how long things will take and am able to be on time for my next appointment. Gulp, I can't believe I just said that out loud. Now Monday's appointments are going to be crazy….
