A cornice molding cap is provided as an accessory to cover or eliminate gaps created where cornice molding meets at a corner of a building. The cap covers gaps where cornice molding meets at a corner structure formed by two walls. The cap is particularly useful in exterior siding installations at corners not employing corner posts having receiver pockets for cladding material end edges. ## Claims ### Claim 1 A method of finishing an uppermost course of exterior siding installed at a corner of a building with a cornice molding comprising: installing a pair of cornice molding trim accessory strips capable of sliding horizontally in receiver channels of cornice receiver strips secured to respective walls of a building that meet at a corner of the building such that the cornice molding trim accessory strips cover a portion of the uppermost course of siding installed at the corner, the cornice receiver strips each being formed into a unitary fastening flange along the cornice receiver strip to fasten to and along one of the corresponding building walls above the uppermost course of exterior siding installed on said one of the corresponding building walls, and each being formed into a unitary ledge along the cornice receiver strip and each being formed under the unitary ledge into a unitary receiver channel and a unitary retainer flange along the cornice receiver strip; each of the cornice molding trim accessory strips is formed into a corresponding unitary mounting flange along the cornice molding trim accessory strip to be received in a corresponding unitary receiver channel formed under the unitary ledge of the cornice receiver strip and retained by a corresponding unitary retainer flange, wherein each of the cornice molding trim accessory strips is formed into a depending unitary bottom along the cornice molding trim accessory strip, the unitary bottom being flexible to conform against surface dimension irregularities on the uppermost course of exterior siding installed on said one of the corresponding building walls without causing a noticeable gap, wherein each of the cornice molding trim accessory strips provides a resiliently biased cantilever beam biased by cantilever beam resiliency to engage the uppermost course of exterior siding installed on said one of the corresponding building walls, and wherein each of the cornice molding trim accessory strips is formed into a unitary raised upper lip along the corresponding unitary mounting flange to abut the soffit and to attach a cornice molding corner cap without entering the corresponding receiver channel formed under the ledge of a cornice receiver strip; and snap fitting a cornice molding corner cap onto the pair of cornice molding trim accessory strips with the cap being in front of and concealing respective ends of the cornice molding trim accessory strips, while the respective ends are spaced apart from each other at an interior corner of a body portion of the cap to allow for expansion and contraction without engaging each other and without abutting the interior corner, wherein the cornice molding corner cap comprises a cap body portion formed into a unitary pair of receiver channels each defined between a hook-shaped unitary upper retaining flange and a hook-shaped unitary lower retaining flange, each said flange extending to an interior corner of the cap body portion and extending laterally of the cap body portion to receive and overlap a corresponding cornice molding trim accessory strip, such that the lower retainer flanges are so constructed and arranged to fit over and cover the depending bottoms along the cornice molding trim accessory strips without a visibly noticeable gap, and the upper retainer flanges are so constructed and arranged to fit over and along the raised upper lips along the cornice molding trim accessory strips, while wedged between the cornice molding trim accessory strips and the soffit without opening a noticeable gap, and the upper and lower retainer flanges are so constructed and arranged to receive the cornice molding trim accessory strips therebetween without fasteners therethrough to allow for horizontal expansion and contraction of the cornice molding trim accessory strips slidably relative to the body portion. ### Claim 2 (depends on 1) The method of claim 1, further comprising: hooking the upper retainer flanges of the cornice molding corner cap over upper lips on respective cornice molding trim accessory strips and pivoting the cap to snap-fit lower retainer flanges over a bottom on the respective cornice molding trim accessory strips to mount the cap in place in a snap-fitting relation. ### Claim 3 (depends on 1) The method of claim 1, further comprising: sliding the cornice molding corner cap over the end of one of the cornice molding trim accessory strips until the cap overlaps and aligns with a surface of the other of the cornice molding trim accessory strips; and snap fitting the cap over the other of the cornice molding trim accessory strips. ### Claim 4 A method of using an assembly, the assembly providing a cornice for abutting a soffit and covering an uppermost course of exterior siding installed on corresponding building walls that meet at a corner of a building, comprising: installing a pair of cornice molding trim accessory strips slidably horizontal in receiver channels of cornice receiver strips secured to respective walls of a building that meet at a corner of the building such that the cornice molding trim accessory strips cover a portion of the uppermost course of siding installed at the corner, the cornice receiver strips each being formed into a unitary fastening flange along the cornice receiver strip to fasten to and along one of the corresponding building walls above the uppermost course of exterior siding installed on said one of the corresponding building walls, and each being formed into a unitary ledge along the cornice receiver strip and each being formed under the unitary ledge into a unitary receiver channel and a unitary retainer flange along the cornice receiver strip; each of the cornice molding trim accessory strips is formed into a corresponding unitary mounting flange along the cornice molding trim accessory strip to be received in a corresponding unitary receiver channel formed under the unitary ledge of the cornice receiver strip and retained by a corresponding unitary retainer flange, wherein each of the cornice molding trim accessory strips is formed into a depending unitary bottom along the cornice molding trim accessory strip, the unitary bottom being flexible to conform against surface dimension irregularities on the uppermost course of exterior siding installed on said one of the corresponding building walls without causing a noticeable gap, wherein each of the cornice molding trim accessory strips provides a resiliently biased cantilever beam biased by cantilever beam resiliency to engage the uppermost course of exterior siding installed on said one of the corresponding building walls, and wherein each of the cornice molding trim accessory strips is formed into a unitary raised upper lip along the corresponding unitary mounting flange to abut the soffit and to attach a cornice molding corner cap without entering the corresponding receiver channel formed under the ledge of a cornice receiver strip; and snap fitting a cap body portion of a cornice molding corner cap onto the pair of cornice molding trim accessory strips with the cap body portion being in front of and concealing respective ends of the cornice molding trim accessory strips, while the respective ends of the cornice molding trim accessory strips are spaced apart from each other at an interior corner of the cap body portion to allow for expansion and contraction without engaging each other and without abutting the interior corner, wherein the cornice molding corner cap comprises a cap body portion formed into a unitary pair of receiver channels each defined between a hook-shaped unitary upper retaining flange and a hook-shaped unitary lower retaining flange, each said flange extending to an interior corner of the cap body portion and extending laterally of the cap body portion to receive and overlap a corresponding cornice molding trim accessory strip, such that the lower retainer flanges are so constructed and arranged to fit over and cover the depending bottoms along the cornice molding trim accessory strips without a visibly noticeable gap, and the upper retainer flanges are so constructed and arranged to fit over and along the raised upper lips along the cornice molding trim accessory strips, while wedged between the cornice molding trim accessory strips and the soffit without opening a noticeable gap, and the upper and lower retainer flanges are so constructed and arranged to receive the cornice molding trim accessory strips therebetween without fasteners therethrough to allow for horizontal expansion and contraction of the cornice molding trim accessory strips slidably relative to the body portion. ### Claim 5 (depends on 4) The method of claim 4, further comprising: hooking the upper retainer flanges of the cornice molding corner cap over upper lips on respective cornice molding trim accessory strips and pivoting the cap to snap-fit the lower retainer flanges over a bottom on the respective cornice molding trim accessory strips to mount the cap in place in a snap-fitting relation. ### Claim 6 (depends on 4) The method of claim 4, further comprising: sliding the cornice molding corner cap over the end of one of the cornice molding trim accessory strips until the cap overlaps and aligns with a surface of the other cornice molding trim accessory strips; and snap fitting the cap over the other cornice molding trim accessory strips.
