Refaced Staircase

Abstract

A refaced staircase having original treads and original risers with replacement treads and replacement risers is disclosed. The original treads include nosings that overhang the original risers. A replacement riser extends down from each original tread, the replacement tread being placed over the original tread and overhanging both the nosing of the original tread and the replacement riser. The replacement tread may include a scotia facing the original tread that hides the seam between the original tread and the replacement riser.

1 . A refaced staircase comprising:
 an original tread adjacent to an original riser, the original riser extending downwardly away from the original tread, the original tread comprising an overhanging portion overhanging the original riser and extending from the original riser to a front end, the front end being on a curved front end portion of the overhanging portion;   a replacement tread and a separate replacement riser, the replacement tread being disposed on top of the original tread, the replacement riser being disposed adjacent to the original riser and flush with the front end of the original tread, the replacement riser and the original tread defining a seam between the replacement riser and the original tread;   the replacement tread comprising an overhanging portion overhanging the front end of the original tread, the overhanging portion of the replacement tread comprising a scotia extending downwardly from said overhanging portion and being immediately adjacent the front end of the original tread, the scotia extending downwardly beyond the said seam whereby the scotia covers the seam.   
     
     
         2 . The refaced staircase of  claim 1  wherein the replacement riser is spaced away from the original riser. 
     
     
         3 . The refaced staircase of  claim 1  wherein the original tread has a tread depth and the replacement tread has a tread depth equal to the tread depth of the original tread. 
     
     
         4 . The refaced staircase of  claim 1  wherein the rise/run ratio defined by the replacement riser and the replacement tread is the same as the rise/run ratio defined by the original riser and the original thread. 
     
     
         5 . The refaced staircase of  claim 1  wherein the replacement riser extends downwardly to a second replacement tread and covers a portion of the second replacement tread, one or more fasteners extending through the portion of the second replacement tread. 
     
     
         6 . The refaced staircase of  claim 1  wherein the original riser is one of a plurality of original risers, and the replacement riser is one of a plurality of replacement risers, each replacement riser being spaced from its associated original riser by a respective set of one or more shims. 
     
     
         7 . The refaced staircase of  claim 1  wherein the original riser is one of a plurality of original risers, and the replacement riser is one of a plurality of replacement risers;
 the staircase extends between an upper landing and a lower landing, a first replacement tread of the plurality of treads is adjacent to one of the upper landing and the second landing, and a second replacement tread of the plurality of treads is adjacent the first replacement tread, each of the first and second replacement treads having upper and lower surfaces separated by the thickness of the tread, wherein the thickness of the first replacement tread is different than the thickness of the second replacement tread. 
 
     
     
         8 . The refaced staircase of  claim 1  wherein the overhanging portion of the replacement tread extends away from the original tread to a front end portion of the replacement tread, the scotia extending downwardly past the front end portion of the replacement tread. 
     
     
         10 . The refaced staircase of claim  9  wherein the front end portion of the replacement tread comprises a curved outer surface. 
     
     
         11 . The refaced staircase of  claim 1  wherein the original tread overhangs the original riser by a width dimension and the replacement tread overhangs the replacement riser by the same width dimension. 
     
     
         12 . A refaced staircase comprising:
 an original tread adjacent to an original riser, the original riser extending downwardly away from the original tread, the overhanging portion of the original tread comprising a bullnose on a front end of the original tread;   a replacement tread and a separate replacement riser, the replacement tread on top of the original tread, the replacement riser being adjacent the original riser and below the original tread, the replacement riser and the original tread defining a seam between the replacement riser and the original tread;   the replacement tread comprising an overhanging portion that overhangs the original tread, at least a portion of the overhanging portion of the replacement tread extending downwardly adjacent the front end of the original tread past the original tread and past the said seam.   
     
     
         13 . The replacement staircase of  claim 12  wherein the replacement riser is spaced away from the original riser and is flush with the front end of the original tread. 
     
     
         14 . The replacement staircase of  claim 12  wherein the bullnose of the original tread has a curved surface extending from the front end of the original tread towards the replacement tread. 
     
     
         15 . The replacement staircase of  claim 12  wherein the replacement tread overhangs the replacement riser by the same amount the original riser overhangs the original riser. 
     
     
         16 . The replacement staircase of  claim 12  wherein the overhanging portion of the replacement tread comprises a flat surface facing the original tread and the replacement riser. 
     
     
         17 . A method of refacing a staircase having an original tread and an original riser extending downwardly from the original tread with a replacement tread and a replacement riser, the original tread having a curved nosing overhanging the original riser and extending away from the original riser to a front end of the original tread, the method comprising the steps of:
 (a) attaching the replacement riser beneath the original tread adjacent to the original riser and flush with the front end of the original tread; and   (b) attaching the replacement tread over the original tread with a nosing of the replacement tread overhanging the nosing of the original tread, the nosing of the replacement tread comprising a scotia extending downwardly past the original tread;   wherein when the replacement tread and the replacement riser are both attached, the scotia of the replacement tread extends downwardly to at least an upper end portion of the replacement riser.   
     
     
         18 . The method of refacing the staircase of  claim 17  wherein when the replacement tread and the replacement riser are both attached, the scotia of the replacement tread comprises a flat surface facing the original tread and the replacement riser. 
     
     
         19 . The method of refacing the staircase of  claim 17  wherein the original riser and the original tread define a rise/run ratio and wherein when the replacement tread and the replacement riser are both attached, the replacement riser and the replacement tread define the same rise/run ratio.
