A sealing assembly is disclosed which may be attached to exterior closures for openings, such as doors, of a building or dwelling for sealing the bottom of the closure against weather and the like. The sealing assembly includes an elongated plate having at least two steps. Each step is defined by a vertical surface and a horizontal surface. An elongated sill is attached beneath the bottom of the closure along the threshold opposite the elongated plate, and the elongated sill has at least two steps defined by vertical surfaces and horizontal surfaces. A sealing strip is disposed along at least two vertical surfaces of the elongated plate for sealing engagement with the corresponding vertical surfaces of the elongated sill, whereby when the closure is closed an insulating air space is provided between the sealing strips. An exterior door and a method for improving the sealing of exterior doors are also disclosed, which utilize the sealing assembly of the present invention.
