An entryway for disposition in a door opening of a building includes a threshold and a corner sealing member mounted in the door opening between the building and the threshold. The threshold has a bottom facing downwardly and a back extending upwardly from the bottom. The corner sealing member has a middle portion disposed partially below the bottom of the threshold, a first vertical portion extending upwardly from the middle portion adjacent the threshold, and a second vertical portion extending upwardly from the middle portion transversely from the first vertical portion. The back of the threshold defines a recess and the second vertical portion of the corner sealing member is disposed in the recess to allow for adequate sealing between the threshold and the corner sealing member and to allow for proper placement of the threshold in the door opening without interference from the corner sealing member.
