Refinish vs new staircase?

Refinishing keeps the existing structure (treads, risers, stringers) and just sands + restains + reseals. Costs $40-$90 per step. A full new staircase is the right answer when treads are cracked, risers are sagging, code requires changes (rise/run, baluster spacing), or you want a different material.

Are oak treads worth it vs pine?

Oak treads ($40-$90 each) are the residential standard for stained finish. Pine ($15-$40) is fine for paint-grade finish. Walnut, hickory, and maple ($80-$180) are premium choices for higher-end homes. Engineered hardwood treads exist but most builders prefer solid wood for runs.

Methodology & sources

What this is: a planning-range staircase calculator informed by HomeGuide, HomeAdvisor, Homewyse, manufacturer (Stairtek, Coffman, Crown Heritage) MSRP, and licensed cost-estimating references.

Labor is modeled from per-unit installed rates with a crew-rate sanity check ($75-$140/crew-hr loaded billing rate), informed by BLS OEWS 47-2031 (Carpenters).

Frequently asked questions

How much does a staircase cost?

$700-$10,000 for most residential scopes. Refinish $1.5-3.5k. New straight run $4-10k. Spiral $3.5-9k. Attic pull-down $700-1.8k.

Refinish vs new?

Refinish $40-$90/step keeps the structure. New install $150-$400/step replaces everything — needed if treads/risers are cracked, code-out, or you want different material.

What hardwood is best?

Red oak is the residential standard ($40-$90/tread). Pine is paint-grade ($15-$40). Walnut/hickory premium ($80-$180). Engineered hardwood OK for treads but most builders prefer solid.

Code requirements?

IRC: max 7-3/4-in rise, min 10-in tread depth, min 36-in headroom over treads, min 36-in handrail height (34-38 in), max 4-in baluster spacing. Older homes often non-compliant; budget for upgrades on full rebuild.

Can I DIY?

Refinish — yes, weekend project for a confident DIYer with a sander. New structural run — pro work, both for code and for the load path.

Common mistakes & questions

Skip the dust extraction — sanding stairs throws fine dust through the whole house.
Stain coat too thick — pools, peels in 1-2 yr. 3 thin coats poly > 1 thick coat.
Baluster spacing too wide — code is 4-in max sphere passage. Hire someone who knows.
New treads on old stringers — measure rise/run for each step. Old stringers warp; not always reusable.
Replace handrail without anchoring to studs — handrails must take 200-lb load per IRC.
Skip permit on full rebuild — insurance may deny fall-injury claims if no permit on file.
Ask your contractor: tread material spec, finish coats, baluster spacing, handrail load test, code-compliance walkthrough.

When this estimate is wrong

Curved or open-stringer staircases are 3-5x straight-run pricing.
Engineered open-rise / floating-tread requires steel stringers and engineering — $15k+.
Glass balustrades 4-8x wood balustrade pricing.
Asbestos in old vinyl runner glue — abatement adds $1-3k.
Historic homes: code may permit non-conforming dimensions; preservation can require matching original profile (premium).
Two-story atrium with skylight overhead — coordinate scopes; ladder access for finish.
