Stair Tread Replacement & Refinish
Handis stair tread replacement and refinish brings worn or damaged wood treads back to a finish that matches the downstairs floor — sand, repair, individual tread replacement, stain and finish, with code-compliant nosing and riser height verified at every step — from $1,500 for a sand-and-refinish on a short flight to $4,500 for a full tread replacement on a 14-tread staircase with finish. The 1948 fir treads ground down to nail heads after 76 years of foot traffic. The 1965 red oak treads where two cracked at the same knot when a piece of furniture got dragged up the stairs. The 1972 maple treads where the polyurethane finish wore through at the high-traffic center and the wood greyed from years of moisture. Every tread sound-checked before the quote. Treads that can refinish get sanded to bare wood, treads that cannot refinish get replaced with matched species, then the whole staircase finishes as one continuous surface. The downstairs floor stain and finish gets sample-matched on an offcut so the staircase reads as part of the same install.

What Does Stair Tread Replacement & Refinish Include?
Stair tread replacement and refinish is the scope that brings worn or damaged wood treads back to a finish that matches the downstairs floor — covering sound-check on every existing tread, individual tread removal and matched-species replacement for treads beyond refinish, sanding to bare wood, subtread repair where the structure has worn or split, stain match to the downstairs floor on a sample offcut, two or three finish coats (water-based polyurethane, oil-based polyurethane, or hardwax oil), and the matched riser paint or stain finish. Handis covers the scope from $1,500 for a sand-and-refinish on a short flight to $4,500 for a full tread replacement on a 14-tread staircase with finish. Code-compliant tread depth, riser height, and nosing overhang are verified before any new tread is installed.
Sound-Check Every Existing Tread Before Quote
Each existing tread sound-checked at the nosing, the center, and the back — a screwdriver tip and a knuckle knock identify cracks, splits, hidden hollow spots from subtread separation, and treads worn beyond refinish depth. The condition of each tread goes on the quote, so the customer sees exactly which treads refinish and which replace. Most 50-plus-year staircases have two to five treads beyond refinish even when the rest of the staircase looks fine.
Individual Tread Replacement with Matched Species
Failed treads removed individually with a flat bar and a circular saw set to the tread depth (never the subtread depth — scoring the subtread creates a new problem). Replacement treads ordered to match the species, thickness, and nosing profile of the originals — white oak, red oak, fir, maple, hickory, or rarer species sourced from a regional reclamation yard where the home is historic. Construction adhesive on the subtread plus structural screws from below where access permits (most older staircases lack the under-stair access for screw-from-below, so the structural fastening is from above with finish-headed screws and matched filler).
Sand to Bare Wood, Match the Downstairs Floor
Treads that pass sound-check sand to bare wood with a belt sander (60 grit, then 80, then 120 grit), edges hand-sanded with a sanding block to keep the nosing crisp, dust HEPA-vacuumed twice before any stain rolls out. The downstairs floor stain gets sample-matched on a tread offcut so the stair-to-floor transition reads continuous. Stain applied per the manufacturer spec (wipe-on, brush-on, or sprayer depending on the product), dry time held per the published window before any finish coat.
Finish Coats — Water-Based, Oil-Based, or Hardwax Oil
Two or three finish coats matched to the downstairs floor. Water-based polyurethane (Bona Traffic HD, Bona Traffic Naturale) for the lowest VOC and the fastest dry time — the most common choice on modern hardwood. Oil-based polyurethane (Minwax Super Fast-Drying Polyurethane, Varathane) for the deeper amber and the traditional look on a fir or red-oak craftsman. Hardwax oil (Rubio Monocoat, Pallmann Magic Oil) for a matte natural look with easy spot-repair. Light hand-sand between coats with 320 grit, dust HEPA-vacuumed before each subsequent coat.
Riser Paint or Stain to Spec
Risers painted (Benjamin Moore Decorator's White, Simply White, or a matched cabinet white from the kitchen) or stained in matched species. Painted risers get a fill-and-caulk pass at every miter and tread-to-riser seam, then two coats of trim paint with a brush or a small sprayer. Stain-grade risers get the same stain-and-finish protocol as the treads, applied separately so the riser and tread sheen match. The riser-to-tread color choice is decided on the quote walk-through against the downstairs floor.
Code Compliance — Tread Depth, Riser Height, Nosing Overhang
Every new or refinished tread is verified against the International Residential Code spec — tread depth minimum 10 inches, riser height maximum 7.75 inches, nosing overhang 3/4 to 1.25 inches, uniformity across the staircase no more than 3/8 inch deviation between the shortest and the tallest riser. Non-conforming existing staircases (common in pre-1970 Seattle homes) get noted on the quote with the deviation measured; we will recommend an adjustment scope if the deviation is unsafe (a more-than-3/8-inch riser variance that has caused a trip).
How a Stair Tread Replacement & Refinish Works
Six sequential steps from sound-check to final finish coat — the actual sequence on every Handis stair tread refinish.
Sound-Check Each Tread and Document Condition
Every existing tread sound-checked at the nosing, the center, and the back with a screwdriver tip and a knuckle knock. Cracks, splits, hidden hollow spots, and worn-through-finish treads get photographed and documented in writing. The condition list goes on the quote so the customer sees which treads refinish and which replace.
Replace Failed Treads with Matched Species
Failed treads removed individually with a flat bar and a circular saw set to the tread depth (never the subtread depth). Replacement treads ordered to match the species, thickness, and nosing profile of the originals. Subtread sound-checked and repaired where needed. New treads dry-fit before adhesive and fastening.
Sand to Bare Wood with Belt Sander and Hand-Sand the Edges
Treads that pass sound-check sand to bare wood with a belt sander (60 grit, then 80, then 120). Edges hand-sanded with a sanding block to keep the nosing crisp. Risers prepped per the riser plan (sanded for stain or filled-and-sanded for paint). Dust HEPA-vacuumed twice before any stain rolls out.
Sample-Match the Stain on a Tread Offcut
Downstairs floor stain matched on a tread offcut — small section of replacement tread stained to the same target color as the existing downstairs floor, dried, and held to the floor for visual confirmation. Match approved by the customer before the full staircase stains. Stain applied per the manufacturer spec, dry time held per the published window.
Two or Three Finish Coats, Light Sand Between
First finish coat applied with a brush, foam pad, or a small sprayer depending on the product. Dried per the published window (typically 2 to 4 hours for water-based, 8 to 12 for oil-based). Light hand-sand with 320 grit between coats, dust HEPA-vacuumed. Second coat applied. Third coat where high-traffic durability is required (most main-staircase scopes).
Riser Paint or Stain Finish, Final Touch-Up
Risers painted (two coats of trim paint with a brush or a small sprayer) or stained (matched species, same finish protocol as the treads). Fill-and-caulk pass at every miter and tread-to-riser seam where painted. Final touch-up on any spot that flagged during the customer walk-through. Stairs held off-limits for the full cure window per the manufacturer spec (typically 24 to 72 hours before normal foot traffic).
Stair Tread Replacement & Refinish Pricing
Final pricing depends on the tread count, the number of treads that need replacement versus refinish, the species match, the finish product, and the riser scope (painted or stained). Each scope is itemized on the quote. Reclaimed historic species (fir, old-growth white oak) for a matched-period staircase is sourced from a regional reclamation yard with the product cost passing through on the quote.

Every tread sound-checked at the nosing, the center, and the back
Each existing tread sound-checked with a screwdriver tip and a knuckle knock — cracks, splits, hidden hollow spots from subtread separation, treads worn beyond refinish depth. The condition list goes on the quote in writing so the customer sees which treads refinish, which replace, and which we recommend leaving in original character. Most 50-plus-year staircases have two to five treads beyond refinish; we do not pretend otherwise.
Matched-species replacement, not a generic builder-grade tread
Failed treads get replaced with matched species — white oak for white oak, red oak for red oak, fir for fir, maple for maple. We source from regional reclamation yards (Earthwise Architectural Salvage, Second Use, Ballard Reuse) when the original is a historic species like old-growth Douglas fir on a 1920s craftsman. A generic builder-grade tread reads like a patch and we do not install one on a real staircase.
Stain sample-matched on a tread offcut, customer-approved before the full stain
The downstairs floor stain gets sample-matched on a tread offcut before the full staircase stains. The offcut dries to final tone and we hold it against the downstairs floor for visual confirmation. Customer approves the match in person or via photo before any stain rolls out on the staircase. No surprises at sign-off.
Code-compliant tread depth, riser height, and nosing overhang verified
Every new or refinished tread is verified against the International Residential Code spec — tread depth minimum 10 inches, riser height maximum 7.75 inches, nosing overhang 3/4 to 1.25 inches, uniformity across the staircase no more than 3/8 inch deviation between shortest and tallest riser. Non-conforming existing staircases are flagged on the quote with the deviation measured and an adjustment scope recommended if the deviation is unsafe.
Finish matched to the downstairs floor — water-based, oil-based, or hardwax oil
Bona Traffic HD or Bona Traffic Naturale water-based polyurethane for the lowest VOC and fastest dry time. Minwax oil-based polyurethane or Varathane for the deeper amber on a traditional fir or red-oak craftsman. Rubio Monocoat or Pallmann Magic Oil hardwax oil for a matte natural look. The finish product gets matched to the downstairs floor so the staircase reads as part of the same install — same sheen, same depth, same touch.
Insured, background-checked, one-year project warranty
Handis carries general liability and workers' compensation; every technician has cleared a background screening. One-year project warranty on the tread workmanship — replacement, sanding, stain, finish, riser paint. A tread that develops a squeak from a missed adhesive bead, a stain that lifts or peels because of an incomplete sand prep, or a finish coat that crazes from an off-spec recoat window gets re-done at no cost. The finish product itself carries the manufacturer warranty (typically 10 to 25 years on premium polyurethanes).
Estimate
Tell us the staircase (tread count, current species and finish, open or closed sides, what is downstairs), the condition of the treads (any that are visibly cracked, worn through, or rocking), and the target finish (matched to existing downstairs floor, new stain color, painted or stained risers). A wide phone photo of the staircase from below plus a close-up of the most damaged tread and a sample of the downstairs floor finish helps us quote without a second round. We send a written estimate with the refinish, the tread replacements, and the riser scope itemized.
Customer Reviews
Stair tread replacement and refinish reviews from real Handis customers.
1948 Madison Park craftsman. Original fir treads were ground down to nail heads at the bottom four steps from 76 years of front-door foot traffic. Handis replaced the four worst treads with reclaimed old-growth fir from a regional salvage yard, sanded and refinished the rest, painted the risers Benjamin Moore Decorator's White. Stairs look like an original 1948 staircase rebuilt to spec.
1965 Ravenna split-level. Two red oak treads cracked at the same knot when we dragged a couch upstairs. Handis replaced both with matched red oak, sanded the rest of the staircase to bare wood, and stained to match our new downstairs hardwood. You cannot tell which treads are original and which are new.
1972 Wallingford modern. Maple treads with the polyurethane worn through at the high-traffic center of every step. The wood underneath was greyed from years of moisture. Tech sanded to bare wood, treated the grey spots with oxalic acid wood brightener, then refinished with Bona Traffic HD water-based polyurethane to match our new downstairs maple floor. Brought the staircase back from the dead.
1924 Queen Anne craftsman. All 13 treads were sound but the original shellac finish had crazed and peeled across the whole staircase. Handis sanded everything to bare wood, treated the worst spots, and refinished with oil-based polyurethane to match the traditional look of the downstairs fir floor. Painted the risers a deep historic cream. Looks like 1924 again.
1957 Burien rambler. All 12 treads were red oak and several were cracked, one was rocking, two had been screwed down by a previous owner with finish-headed screws that were obvious from above. Handis replaced the five worst treads with matched red oak, sanded the rest, filled the screw holes invisibly, finished with hardwax oil for a natural matte look. Staircase looks like custom millwork.
