Carpeted Stairs to Hardwood: What It Actually Costs in Seattle — and When Refinishing Beats Replacing
Nobody knows what’s under their stair carpet until it comes up. Sometimes it’s beautiful fir that just needs sanding. Sometimes it’s rough construction pine that was never meant to be seen. This guide explains how to tell the difference, what each path costs in the Seattle and Eastside market in 2026, and how to read a stair quote without getting burned.

Stairs are the single most-quoted, least-understood line item in a flooring project. This guide is the same walkthrough we give homeowners on site — including the times we tell people to leave the carpet alone for now.
Stairs are their own craft
Treads, risers, nosings, skirtboards, landings, and railings — stair work is finish carpentry, not just flooring
We pull the carpet first
We don’t quote stairs blind. A corner of carpet comes up before anyone commits to a number

Craftsman fir, mid-century splits, Eastside tri-levels — each one hides something different under the carpet
“We just refinished our floors — now the carpeted stairs look terrible.”
This is how the stair conversation almost always starts. A homeowner in Wallingford or Kirkland finishes their main-floor hardwood, walks into the entry, and the beige stair carpet is suddenly the loudest thing in the house. Everything else looks new. The stairs look like 1998.
The instinct is to assume this is a small job. It isn’t — but it also isn’t always the expensive job people fear. Stairs cost more per square foot than any floor in the house because each tread is a separate, hand-fitted piece with edges, returns, and a nosing that has to be sanded and finished by hand. A staircase might only be 60 or 80 square feet of surface, and still take as long as a bedroom.
But here’s the part that actually determines your price, and it has nothing to do with the wood you pick: what’s underneath the carpet right now. The biggest pricing variable in a stair project is what the carpet is hiding. If there’s real hardwood under there, you’re in the cheaper conversation. If it’s plywood or rough pine, you’re in the more expensive one. Everything else is a rounding error by comparison.
Key insight: Never accept a stair quote from someone who hasn’t looked under the carpet. A contractor quoting stairs sight-unseen is either padding the number heavily or setting up a change order later. Both cost you.
What’s actually under your stair carpet — and how to find out in ten minutes
You can check this yourself before you call anyone. Pull up a corner of carpet at the top step, near the wall where the tack strip ends. It’ll come up with some effort and it’s easy to press back down. What you see tells you almost everything about your budget.
Good news: real hardwood treads
You’ll see a solid board — usually fir, oak, or maple — with visible grain and a rounded front edge (the nosing) that overhangs the riser. Often there’s a finished strip along both sides where the runner didn’t cover. This is a refinishing job.
- Grain runs the full width of the tread
- A shaped, rounded nosing on the front edge
- Old finish or stain visible near the edges
- Staple holes are common and repairable
Harder news: construction-grade subtreads
You’ll see plywood, particleboard, or wide rough pine with a squared-off front edge and no nosing. These were built to be covered and were never finished. Sanding them won’t produce a floor you’d want to look at. This is a new-tread job.
- Plywood layers or particleboard visible at the edge
- Square front edge with no shaped nosing
- Gaps, knots, or gouges left by the framer
- No finish anywhere, including the sides
There’s a third case we see constantly on the Eastside: hardwood treads paired with painted or particleboard risers. That’s normal — many builders used real wood where you step and cheap material where you don’t. It’s an easy hybrid: refinish the treads, paint the risers white. It’s also one of the best-looking and most cost-effective stair results available, and it’s the current design default in most new Sammamish and Issaquah construction.
One honest warning: carpet is rarely kind to the wood underneath it. Expect staple holes, tack strip marks along the edges, and sometimes adhesive residue. Nearly all of it sands out. Occasionally it doesn’t, and we’ll tell you that before you’ve spent anything.
Refinish what’s there, or install new treads? Six factors that decide it.
Once you know what’s under the carpet, the choice usually makes itself. Here’s how each factor breaks down — honestly, including the cases where the more expensive option isn’t worth it.
1. Cost per step
Refinishing existing treads runs a fraction of new tread installation. In the Seattle–Bellevue market, stair refinishing lands around $85 to $100 per tread, while new hardwood treads and risers run $200 to $400 per step installed. On a 14-step staircase that’s roughly a $1500 job versus a $3,500 to $6,000 one. If you have real wood down there, refinishing is close to a default answer.
2. Matching your existing floors
This is the reason most people end up replacing rather than refinishing. If your main floor is white oak and your stair treads are fir, no stain will make them match — different species take color completely differently, and the grain patterns read as obviously different from across a room. When the stairs are visible from the main living area, matched species matters more than the savings. When the staircase is tucked behind a wall, it matters much less.
3. Structural condition and squeaks
Refinishing sands the surface. It does nothing for a tread that flexes, a loose riser, or the squeak on step four you’ve been stepping around for a decade. Pulling treads gives access to shim, glue, and re-secure the stringers. In older Seattle homes with genuine movement in the staircase, replacement solves a problem refinishing can only hide. Note that Seattle stair repair alone runs $120 to $350 per step, so if repairs are needed anyway, the gap to full replacement narrows considerably.
4. Disruption and time in your home
This is the factor homeowners underestimate. A staircase is not a room you can close off — it’s the only way to the second floor. Refinishing typically takes two to three days, with the stairs usable in stages or overnight. Full tread replacement takes three to five days and there are periods where the staircase genuinely can’t be used. For families with small kids, elderly parents, or a single staircase in the home, that logistics difference is worth real money.
5. Long-term durability
An old-growth fir tread from a 1920s Craftsman is often denser and more stable than anything you can buy new. Refinished properly, it will outlast most of us. New white oak treads will too. The durability difference between the two paths is smaller than the marketing suggests. What actually determines stair longevity is the finish quality and how many coats went on the high-wear nosings — not whether the wood is new.
6. Resale impact
In Bellevue, Mercer Island, Clyde Hill, and Medina, an open staircase visible from the entry is one of the first things a buyer registers walking through the door. Matched, current-looking treads photograph well and read as “recently updated.” A well-refinished older staircase reads as “well maintained” — which is good, but different. Below the neighborhood median price point, refinished stairs are more than sufficient and the money is better spent elsewhere. See our guide to the highest-ROI flooring upgrades before selling for where stairs rank against other pre-listing work.
Four things about Seattle-area homes that change the stair math
Stair projects here don’t follow national cost guides cleanly. Our housing stock, our climate, and our labor market all push the numbers in specific directions.
Split-levels and tri-levels have two staircases
Enormous swaths of Kirkland, Redmond, Bothell, and Newcastle were built as split-entry or tri-level homes in the 60s and 70s. That means a short flight up and a short flight down from the entry — and homeowners routinely budget for one. Count your steps before you plan. Two half-flights of eight steps costs more than one flight of fourteen, because setup, edge work, and finishing happen twice.
Craftsman fir needs a different hand
Seattle’s 1900–1930 housing stock — Ballard, Wallingford, Queen Anne, Mount Baker, Columbia City — is full of old-growth vertical-grain fir stairs. It’s beautiful and it’s softer than oak, which means aggressive sanding takes off more than it should and the wrong stain goes blotchy fast. Fir stairs should be sanded conservatively and often look best with a clear or lightly toned finish rather than a heavy stain. Our refinishing guide covers the same principle for fir floors.
Damp air affects finish cure times
Pacific Northwest humidity slows finish curing, and stairs are the worst place in the house to rush it — every tread nose gets full body weight and shoe grit from day one. In the wetter months we plan for longer cure windows and stage the work so one side of the staircase stays walkable. Local pros consistently note that Seattle’s damp climate makes proper finishing and sealing of wooden stairs especially important to prevent moisture damage.
Seattle labor runs above national averages
National cost calculators will underquote you here. Urban and coastal markets including Seattle typically run 15–25% above published national stair ranges. Seattle’s cost of living sits roughly 44% above the national average, and there’s another 10.55% in sales tax on top of the project total. Budget from local numbers, not from a national calculator.
Which stair path fits your home? Find the one that sounds like you.
These are the six situations we walk into most often across Seattle and the Eastside — and what we actually recommend in each.
Refinish. Almost certainly. Old-growth fir is worth preserving and you can’t buy its equivalent new at any price. Go conservative on the sanding, skip the dark stain, and let the grain do the work. Budget in the $900–$1,400 range for a typical flight.
New white oak treads, with painted risers. Species mismatch is the one problem refinishing genuinely cannot solve. If the staircase is visible from your new floors, matching it is worth the spend. If it isn’t visible, reconsider.
Hardwood treads with a runner down the center. This is the honest answer people don’t expect from a flooring contractor — bare wood stairs are genuinely slipperier than carpet, for dogs and for people. Finished wood on the sides with a quality runner in the middle gives you the look and the traction.
Look at the entry sightline first. If the staircase is the first thing a buyer sees, update it — matched treads and crisp white risers photograph exceptionally well. If it’s tucked away behind a wall, refinish or leave it and put that budget into the main floor instead.
Replace, and address the structure while the treads are off. Refinishing a staircase with real movement in it is money spent on the wrong problem. Once repairs are in the quote anyway, the step up to new treads is smaller than you’d think.
Leave it. We mean this. Stairs are the most expensive square footage in your house and among the least visible from most rooms. If the budget only stretches to one thing, put it into the main-floor living areas — the visual return is dramatically higher. The stairs will still be there next year.
The hybrid most Seattle homeowners land on: real hardwood treads, painted white risers, and a runner down the center. It costs less than an all-wood staircase, solves the slipping problem, hides the most heavily worn part of each tread, and matches the design direction of nearly every recent Eastside remodel. It’s the option we build most often.
What stairs actually cost in Seattle and the Eastside right now
Most Seattle-area staircases have 12 to 17 steps in a standard one-story flight. These are realistic 2026 planning ranges for this market — not national averages. Complex layouts, curved stairs, and multiple landings sit above these numbers.
| Scope of work | Cost per step | Typical 15-step flight | Notes |
|---|---|---|---|
| Carpet removal only | — | $100 – $300 total | Includes tack strip and staple pull; often folded into the main quote |
| Refinish existing treads | $85 – $100 per tread | $1275 – $1,500 | Seattle–Bellevue average; hand-sanded nosings drive the per-unit cost |
| Refinish treads + paint risers | $100 – $130 per step | $1,500 – $1,950 | The most common request; crisp white risers transform the look |
| Retro-fit overlay treads | $150 – $250 per step | $2,250 – $3,750 | New wood over existing subtreads, no demolition — saves $300–$800 in labor |
| Full tread + riser replacement | $250 – $300 per step | $3,750 – $4,500 | Includes demo; allows structural repair and squeak elimination |
| Stair repair (per damaged step) | $120 – $350 per step | Varies by count | Seattle-specific range; loose risers, split treads, tightening stringers |
| Handrail (replace) | $70 – $90 per linear ft | ~$1500 average | Often quoted separately — always ask if it’s included |
| Balusters / spindles | $10 – $25 each | $1,200 – $1,600 | Swapping wood spindles for iron is the single biggest visual upgrade per dollar |
How to compare two stair quotes honestly: a stair estimate should separate the visible wood from everything else. One bid may cover treads only. Another may include risers, skirtboards, railings, repairs, finishing, and cleanup. A $2,100 quote and a $3,400 quote often describe completely different jobs. Ask both contractors to itemize: treads, risers, railing, repairs, finish coats. Then compare. Try our Seattle flooring cost calculator to sanity-check the overall project.
One more line item people forget: Washington sales tax adds roughly 10.55% to the project total in most of King County. On a $3,000 staircase, that’s another $315 you should have in the budget from day one.
Refinishing vs. new treads, side by side
| Category | Refinish existing treads | New treads & risers |
|---|---|---|
| Requires | Real hardwood already under the carpet | Works over any subtread condition |
| Cost, 14-step flight | $1,700 – $2,000 | $4,400 – $6,200 |
| Time in your home | 2 – 3 days including cure time | 3 – 5 days, longer with repairs |
| Fixes squeaks & movement | No — surface work only | Yes — full access to the structure |
| Species matching | Limited to what’s already there | Exact match to new floors |
| Preserves original wood | Yes — key for period Craftsmans | No — original material is removed |
| Repeatable later | Yes, several more times | Yes, once installed |
| Best for | Older homes, sound stairs, tighter budgets | Species mismatch, structural issues, premium resale |
If you’re weighing stairs as part of a larger project, our guides to hardwood installation cost in Seattle and solid vs. engineered hardwood cover how the rest of the floor plan affects your stair decision — engineered flooring, for example, still requires solid treads on the stairs.
