A custom staircase in New Hampshire generally costs between $4,000 and $20,000, with a simple straight-run staircase near the lower end and curved, spiral, or floating designs running $20,000 to $60,000 or more. The final price comes down to the staircase type, the materials and railing you choose, and whether you’re building new or restoring an existing stair.
A staircase is one of the few elements in a home that is both structural and sculptural — it has to be code-compliant and safe, and it’s often the first thing a visitor sees. MH Woodworking has specialized in building and restoring custom staircases and railings across New Hampshire since 1987, and this guide lays out what actually goes into the cost.
Custom staircase cost in NH by type
Staircase pricing scales with geometry and joinery. The more a staircase curves, floats, or departs from a straight run, the more layout, fabrication, and skilled labor it requires. Treat the ranges below as planning brackets; exact pricing is set during design.
| Staircase type | Typical NH cost | Notes |
| Straight staircase | $4,000 – $10,000 | Most economical; simple run between two levels |
| L-shaped / U-shaped (with landing) | $8,000 – $18,000 | Added framing, landings, and turns increase labor |
| Curved staircase | $20,000 – $50,000+ | Complex layout and joinery; a true statement piece |
| Spiral staircase | $12,000 – $40,000 | Space-saving; cost varies widely with material and diameter |
| Floating / open-riser | $18,000 – $60,000+ | Engineered mounting and premium finish work |
Refinishing or restoring an existing staircase is a separate, usually lower-cost path — see below.
What affects the price of a custom staircase
Staircase type and layout
A straight run is the simplest and least expensive to build. Every turn, landing, or curve adds framing and fabrication. Curved and floating staircases require the most engineering and craftsmanship, which is why they sit at the top of the range.
Wood species and materials
Treads, risers, stringers, and railings can be built from paint-grade poplar up through red oak, maple, cherry, and walnut. Premium hardwoods and figured grain raise material cost, and mixed-material designs (wood with iron or steel) add another layer.
Railings and balusters
The railing system is a major cost driver and the most visible design choice. Traditional turned-wood balusters, wrought-iron balusters, and modern cable or glass railings each carry different price points. Our guide on wood vs. iron vs. cable railings breaks down the trade-offs in cost, look, and maintenance.
Newel posts and custom detail
Hand-turned or box newel posts, volutes, and custom profiles are where a staircase becomes unmistakably custom. These details reward craftsmanship and are a signature of a purpose-built stair versus a stock kit.
New staircase vs. refinishing an existing one
Not every project calls for a full rebuild. If your staircase is structurally sound but dated or worn, refinishing treads and railings, replacing balusters, or swapping a railing style can transform the look for a fraction of the cost of new construction. Restoration typically runs a few thousand dollars depending on scope, versus tens of thousands for a fully custom build. If you’re unsure which path fits, that’s exactly the kind of thing we assess during a consultation.
Don’t forget NH stair code
Staircases are governed by building code — tread depth, riser height, railing height, and baluster spacing all have requirements, and they exist for safety. A reputable builder designs to code from the start, which protects you at inspection and resale. For a plain-English overview, see our post on NH stair code compliance basics.
Why craftsmanship matters on a staircase
A staircase is used every day and is expected to last for decades, so the quality of the joinery is not cosmetic — it’s what keeps treads from squeaking and railings from loosening over time. MH Woodworking has built and restored custom staircases across New Hampshire since 1987, handling design through installation in-house so the fit, the finish, and the structure are all accounted for by the same team.
Frequently Asked Questions
How much does a custom staircase cost in NH?
Most custom staircases in New Hampshire range from $4,000 for a simple straight run to $60,000 or more for curved or floating designs. Type, materials, and railing choice are the biggest cost drivers.
Is it cheaper to refinish or replace a staircase?
Refinishing is almost always cheaper than replacing. If the structure is sound, refinishing treads and railings or updating balusters can modernize a staircase for a fraction of a full rebuild.
What is the most affordable type of staircase?
A straight-run staircase is the most economical because it requires the least framing and fabrication. Curved, floating, and spiral designs cost more.
How long does it take to build a custom staircase?
Timelines vary with complexity, but a custom staircase typically takes several weeks from design approval through fabrication and installation.
