Charing Mill is a three-storey smock mill on a single-storey base. It has a Kentish-style cap. It had two common sails and two spring sails and was winded by a fantail. The cast-iron windshaft carries a wooden brake wheel driving a wooden wallower, carried on a wooden upright shaft. The wooden clasp arm great spur wheel survives, but the three pairs of millstones have been removed. The mill was originally painted white overall, but the body of the mill was creosoted in 1969.
