At Stairs Unlimited, we know that on time delivery is important to our customers. Our carpet-grade stairs are typically ready to ship 6 business days after receiving an order.


Our box stairs are routed for tighter, more secure joints.

Our box stairs are routed for tighter, more secure joints. Treads and Risers are glued and screwed in place. Each tread is screwed into the riser below in order to provide a tighter glue joint. We use only wood wedges and they are glued and stapled in place. Wood wedges provide a better glue bond than plastic wedges.

We also build notched stairs, radius stairs, fan stairs and starter steps to customize your stair.
