What is the cost to refinish hardwood stairs including treads, risers, and railings in a New Brunswick home?

Refinishing hardwood stairs in New Brunswick typically costs $800–$2,500 for a standard 12–15 step staircase, depending on the scope of work, condition of the wood, and whether you're refinishing treads only or the full assembly including risers and railings.

The wide price range reflects how labour-intensive stair refinishing is compared to flat floor refinishing. Unlike an open floor where a drum sander covers ground quickly, stairs require hand-sanding or orbital sanding on every individual tread, riser, spindle, and railing section. There's no shortcut — every surface needs to be abraded, cleaned, stained (if desired), and coated with multiple layers of finish. Expect to pay $50–$120 per step for treads and risers combined, plus $200–$600 for railing and baluster refinishing depending on complexity.

Breaking Down the Costs

Treads are the most labour-intensive component. Each tread needs to be sanded back to bare wood (or scuff-sanded if the existing finish is in good shape), which takes 20–40 minutes per tread by hand. Staining adds another step. Two to three coats of polyurethane or oil-modified finish follow, with light sanding between coats. Tread refinishing alone typically runs $30–$70 per tread in the NB market.

Risers (the vertical faces between treads) are often painted rather than stained, especially in older NB homes where risers are pine or poplar rather than oak. If your risers are painted, a professional will typically clean, sand, prime, and repaint them rather than strip to bare wood — this costs $15–$30 per riser. If they're stained hardwood matching the treads, add similar labour to the tread cost.

Railings and balusters are where costs vary most dramatically. A simple square-profile oak handrail with straight balusters might cost $200–$400 to refinish. Ornate turned balusters, curved newel posts, or decorative profiles require hand-sanding every contour — that can push railing refinishing to $500–$800 or more for a detailed Victorian or craftsman-style staircase common in older Saint John, Fredericton, and Moncton homes.

NB-Specific Considerations

New Brunswick's winter heating season is brutal on stair finishes. Forced-air heat drops indoor humidity to 20–30% RH from October through April, which causes wood to contract and finish to micro-crack over time — especially on treads that flex slightly under foot traffic. This is why NB staircases often look worn and checked even in relatively young homes. When refinishing, choose a finish with good flexibility: oil-modified polyurethane (3–4 coats) or water-based polyurethane with a commercial-grade formula both perform well in NB's humidity swings. Avoid thin, single-coat finishes that won't hold up through a Maritime winter-summer cycle.

Timing matters too. Late summer through early fall (August–October) is ideal for stair refinishing in NB — humidity is moderate and stable, finishes cure properly, and you're not fighting the extreme dryness of heating season or the high humidity of a Maritime summer. Avoid refinishing stairs in January or February when indoor humidity is at its lowest; finishes can dry too fast, raising grain and reducing adhesion between coats.

Practical Tips

Get quotes that specify number of coats, finish product, and whether staining is included — these details account for most of the price variation between contractors. Ask whether the quote includes moving furniture, masking adjacent surfaces, and cleanup. Confirm the contractor will allow proper dry time between coats (minimum 4–6 hours for water-based, 8–12 hours for oil-modified) rather than rushing the job in a single day.

If your existing finish is simply dull but not deeply scratched or worn through to bare wood, a screen-and-recoat (scuff-sanding and adding 1–2 fresh coats without full sanding) costs significantly less — roughly $25–$50 per tread — and can add years of life to the finish.

When to Hire a Pro

Stair refinishing is firmly in professional territory. Drum sanders cannot be used on stairs, but even orbital and detail sanders require experience to avoid creating flat spots on curved profiles or burning through veneer on engineered treads. Drips and lap marks in stair finish are highly visible and difficult to correct without re-sanding. The confined space and awkward angles make this one of the most technically demanding refinishing jobs in a home.
