If you own a 1,200-pound (544-kilogram) grand piano, you're in trouble. These instruments are oddly shaped, extremely heavy and very difficult to get into a new home. Many people simply hire a piano moving service to do the dirty work for them -- and that may be the best idea, especially if your new home is going to present a challenge. For example, piano movers have been known to use a crane to hoist the piano through a window. Otherwise, the job usually requires a special piano dolly. If you're moving to a building with a freight elevator, you're in luck.
