Staircase Build & Replacement

A staircase is a structural element, a safety feature and often the centerpiece of a home. Rise, run, headroom and handrails are controlled by code, and the details of the stringers and treads decide how the stairs feel under your feet. NorTech connects you with a verified licensed carpenter who measures your space and bids the staircase in writing.

Layout, rise and run, and the shape of the stair

Building codes limit riser height, tread depth and headroom, and every step must be equal within a small tolerance. The carpenter measures the total rise between floors and the available run, then calculates the number of steps. Straight, L-shaped, U-shaped and spiral stairs each have different footprints and rules. The layout also affects how furniture is carried and how the stair looks from the entry. Gather photos of the stairs you like, measurements of the opening and the floor-to-floor height, and share them so the first sketch is close to your idea.

Materials, joinery and finish

Treads and risers can be oak, maple, pine, painted wood or metal, with stringers cut from solid lumber or engineered material. Open risers, floating treads and glass guards create a modern look, while closed stringers and turned balusters suit traditional homes. Joinery and fastening determine squeaks and durability. Ask for samples of the wood species and stain, and discuss slip resistance and noise. Choose the finish early, since stain and clear coats need drying time and the stairs may be out of use while they cure.

Guards, handrails, permits and inspection

Handrails must be graspable and continuous, and guards must keep a small child from passing through openings, with strong posts and connections. The staircase is a permitted structural element, with inspection of the framing and final installation. Replacement stairs in occupied homes require protection of floors and a plan for access. Keep drawings and inspection records, and finish the stairs with a durable coating that resists wear. Walk the finished stairs with the carpenter and test the handrail grip, the guard strength and any squeaks before you sign off.
