A method of arranging an overhead sectional door (SD) in a doorframe () that defines a door opening, the overhead sectional door (SD) comprising a plurality of door panel sections (). The method disclosed herein involves: a) fitting a first door panel section () in the doorframe (), b) fitting a second door panel section () in the doorframe (), and c) actuating an electric motor (M) to cause the first door panel section () to push the section door panel section () a distance in an upward direction. The method further involves: d) securing the second door panel section () with respect to the doorframe (), e) causing said at least one electric motor (M) to move the first door panel section () a distance in a downward direction, thereby leaving a space () between the secured door panel section and the first door panel section (), f) fitting a next door panel section () in the space (), and g) causing said at least one electric motor (M) to move the first door panel section () a distance in an upward direction. Further, the method involves: h) unsecuring the secured door panel section () with respect to the doorframe (), causing said at least one electric motor (M) to move the first door panel section () a further distance in an upward direction, engaging the top edge of the next door panel section () with the bottom edge of the previously secured door panel section (), and securing the next door panel section () with respect to the doorframe (). The method also involves repeating steps e) to h) for each next door panel section () until at least all but a last door panel section of the overhead sectional door (SD) have been arranged.
