We are able to move upright pianos that are under 600 lbs. If it fits in the stairwell safely, our crew will happily move it up or down stairs for you. Baby Grand Pianos: Some of our crews are able to move baby grand pianos that are under 600 lbs, but we can not move them up or down stairs. They must be first floor-to-first floor moves only. We are not able to move grand pianos. Our apologies.
