Our estimator carries tread samples to Columbia in the truck. Lay one at the bottom of your stairs beside the floor and the right wood is plain to see.
Before a new tread goes on, the crew screws each loose step to the stringers. The tread is then scribed to the skirt board, set in adhesive and fastened down for good.
A licensed, insured and NWFA certified crew builds every Columbia staircase, and the labor is warrantied for one full year.

Yes, our labor carries a one-year warranty. The crew building your stairs is licensed, insured and NWFA certified.
