How Much Does a Stair Remodel Cost in Seattle? (2026)

Most stair remodels in Seattle range from $4,500 to $15,000, with simple tread replacement starting around $150/step and high-end floating staircases starting near $15,000. The final number depends on the number of steps, the wood species, and the railing style you choose.

What drives the cost of a stair remodel?

1. Number of steps

A typical staircase has 12–16 steps. More steps means more material and labor, so a tall two-story run costs more than a short flight.

2. Wood species & finish

Oak is the most common and cost-effective; walnut and exotic species cost more. Custom stains and matching to your existing floors add some labor but create a seamless look.

3. Railing style

Cable railing is the most-requested modern style and is moderately priced. Glass railing sits at the high end. Iron and wood railings cover the middle. (See our cable vs glass railing guide.)

4. Structural vs cosmetic work

Cosmetic remodels (new treads, risers, railing) are far cheaper than structural changes or a brand-new floating staircase, which involves engineering and steel fabrication.

How long does a stair remodel take?

A typical remodel (12–16 steps plus railing) takes 3–5 days. Railing-only projects are often done in 1–2 days; floating staircases take 5–10 days depending on complexity.

Do you need a permit?

Cosmetic remodels — tread replacement or a railing swap — generally don't require a permit in Seattle. New installations or structural changes do. We coordinate any permits when they're needed.
