Abstract
A staircase and method for producing the same. The staircase is produced by double routing channels for sub-treads and sub-risers and capping risers and capping treads. These sub-treads and sub-risers are assembled into staircase stringers that have pre-routed channels that are sufficient to install sub-treads and sub-risers having a particular thickness and having room for subsequent placement or installation of capping treads and risers by sliding them laterally into the channels created by the double routing of the stringers. This creates a more finished look to be (the) staircase while avoiding damages to the capping treads and risers that might occur during building construction.
