One of the best things that you can do is to clear the space where the movers will enter to pick up your piano. Ensure there is a clear path between the piano and the door. It is also a good idea to clear the staircase and any other areas where the movers may go to get your piano outside.
Another helpful tip is to ensure there is space for the movers to park the moving van. It should be close to the door of your home or apartment building to make the process easier.
