A method of installing a window assembly within a metal garage door having front and rear exposed surfaces and at least one opening provided therein, the method comprising the steps of: providing a front window frame member formed in one piece of a synthetic, polymeric material, the front window frame member having a central opening and having a periphery sized to circumscribe the window opening from the front exposed surface of the door; providing a rear window frame member also formed in one piece of a synthetic polymeric material and having a central opening and a periphery sized to circumscribe the window opening from the rear exposed surface of the door; providing snap-fit engagement elements about the peripheries of the front and rear window frame members which snap together in mating fashion by pressing the front and rear window frame members together; providing access openings in the rear window frame member at spaced intervals about the periphery thereof in alignment with the engagement elements when the frame members are assembled; installing the front window frame member within the garage door opening on the front exposed surface thereof; locating a transparent pane within the central opening of the front window frame member; installing the rear window frame member on the opposite, rear exposed surface of the door opening to thereby mount the frame members within the window opening with the transparent pane being sandwiched between; pressing the front and rear window frame members together in order to engage the snap-fit engagement elements; using a hand tool to disengage the snap-fit engagement elements, the hand tool being inserted into the frame access openings of the rear window frame member to disengage the engagement elements; separating the window frame members; removing the existing transparent pane from between the two window frame members; installing a new transparent pane between the two window frame members; and again engaging the window frame members within the garage door opening.
