Stair cap and railing install

My younger brother and I had the opportunity to work for a former highschool teacher. He and his wife wanted to have the existing builder grade stairs capped and a railing installed at their home. It was a seamless install, one day in and out. The client had all the stair materials prefinished for us. This is one approach more installers should entertain. Yes, the plugs need to be touched up, but that is minor when the majority of install is already done. Prefinish for the win!
