The seam cover includes an intermediate web with two opposite flanges extending in opposite lateral directions from an edge of the web, forming a general T-shaped cross-section. The seam cover is configured to be installed with the web between two adjacent pieces of building trim with the respective flanges concealing an edge of one of the trim pieces. The seam cover is fixed to one, but not both pieces of building trim.

         8 . The building trim system of  claim 4 , wherein the cover member is rigidly attached to either the first piece of building trim or the second piece of building trim, but not both pieces of building trim. 
     
     
         9 . The building trim system of  claim 4 , wherein the first front flange and second front flange are different sizes. 
     
     
         10 . The building trim system of  claim 9 , wherein the first front flange is shorter than the second front flange. 
     
     
         11 . The building trim system of  claim 4 , wherein the first and second front flanges combine to define a front side of the cover member, and the front face side of the first piece of building trim, the front side of the second piece of building trim and the front side of the cover member each has a height that is substantially coextensive with one another. 
     
     
         12 . The building trim system of  claim 4 , wherein the first and second pieces of building trim combine to form a peripheral edge with a non-linear angle and the cover member includes a corner edge that substantially matches the non-linear angle of the peripheral edge. 
     
     
         13 . The building trim system of  claim 12 , wherein the non-linear angle is approximately 90°. 
     
     
         14 . The building trim system of  claim 4 , wherein the first of the flanges has a first length L 1  and the second of the flanges has a second length L 2  that is greater than the first length L 1 , and wherein a ratio of L 2 :L 1  is within an approximate range of 10:1 to 2:1. 
     
     
         15 . A building trim system, comprising:
 a first piece of building trim having a flat front side with a height and extending laterally from a leading edge to a trailing edge, the first piece of building trim being configured for attachment on a building structure with the flat front side facing outward;   a second piece of building trim having a flat front side with a height and extending laterally from a leading edge to a trailing edge, the second piece of building trim being configured for attachment on a building structure with the flat front side facing outward and its leading edge proximate the trailing edge of the first piece of building trim;   a cover member with a substantially T-shaped cross section comprising a web extending from a front edge to a rear edge and having opposite sides, a first flange extending laterally from the front edge in a first lateral direction and a second flange extending from the front edge in a second lateral direction opposite from the first lateral direction, the first and second flanges combining to form a substantially flat front cover face with a height, wherein   the cover member is positioned with the web extending between the trailing edge of the first piece of building trim and the leading edge of the second piece of building trim with the trailing edge of the first piece concealed behind the first flange and the leading edge of the second piece concealed behind the second front flange, and   the cover member is rigidly attached to either the first piece of building trim or the second piece of building trim, but not both pieces of building trim.   
     
     
         16 . The building trim system of  claim 15 , wherein the front side height of the first piece of building trim, the front side height of the second piece of building trim and the height of the front cover face are coextensive with one another.
