Stairwells are where piano moving becomes significantly more difficult and significantly more dangerous. The gradient of the stairs, the width of the staircase, the presence of landings or turns, and the type of piano all affect how the move is planned and executed.
For upright pianos on staircases, the crew typically uses a combination of stair rollers, piano boards, and controlled lowering techniques that distribute the weight and keep the piano stable throughout the descent or ascent. For grand pianos, disassembly must be completed before the board reaches the stairs. Knowing how to move a piano on a staircase is not something that can be safely improvised by a crew without specific training and equipment. It requires advance planning, the right tools, and enough trained hands to manage the weight at every point on the route.
Tight doorways present a different challenge. Uprights in particular can be wider than they appear once depth is factored in. When a standard doorway will not accommodate the piano in an upright position, the crew will typically tilt the instrument onto its side on the dolly, which requires additional coordination and padding to protect the cabinet during the maneuver.
