Curved, Winding and Unusual Stairs: What the Assessment Covers
Why curved, spiral and open-sided stairs need a closer assessment, and what information helps. Last reviewed 2026-10-25. Written by the Ansley Park Stair Remodeling editorial team. See our editorial policy.
Why these stairs are different
Each tread on a curved or winding stair can be a unique shape. Handrails may follow a curve and need bent sections or special fittings. That makes measurement and templating a bigger part of the job.
What the contractor may check
- Tread shapes and whether templates are needed
- Rail curvature and available fittings
- How treads meet curved walls or open stringers
- Access for long or bent parts
Helpful information to share
- Photos from several angles
- Whether the curve is constant or changes
- Which parts you want to change
Questions
Can every contractor work on curved stairs?
Not necessarily. Mention the stair shape in your request so the referral goes to a contractor who takes that work.
