An adjustable sill assembly includes a substrate base; a sill plate connected with the substrate base; a riser having a top and two downwardly-extending legs defining an interior of the riser, said interior of the riser having a first flange and a second flange angling downward and toward one another; and means for supporting the riser on the substrate base including an adjusting screw and a corresponding T-nut, said adjusting screw having a head adjacent the substrate base and said T-nut slideably supported by the first and second flanges and wherein the riser is supported by the substrate base by threading the adjusting screw into the T-nut. In another embodiment, the adjusting screw is provided with a head that extends beyond at least one of the downwardly-extending legs of the riser to allow engagement and turning of the adjusting screw from the side of the riser.
