Metropolis Moving carried a large, steel, sculptural installation, from the ground floor to the rooftop. The piece was disassembled, but the move involved packing the elements into a passenger elevator, taking them to the 4th floor and then carrying each element up two flights of stairs, and around tight corners. Nothing was damaged. The movers were capable and extremely hard working and the move was completed efficiently. We plan to use this company again next month. I give them my highest recommendation.
