Stair refinishing in Chicago is one of the most impactful home improvements you can make — and one of the most misunderstood. After 18 years renovating staircases across Chicago bungalows, greystones, two-flats, and North Shore homes, here's exactly what the process involves, what it costs, and what surprises come up in older Chicago homes.

Refinish vs. Replace Stair Treads — How to Decide

The first question we answer on every stair project: can these treads be refinished, or do they need to be replaced? The answer depends on the wood species, the condition of the structure, and what's realistically achievable.

✅ Refinishing works when:
→ Treads are solid hardwood (red oak, white oak, maple)
→ Structure is sound — no major movement or settling
→ No large cracks running through the tread
→ Enough wood thickness remains for sanding
→ Surface scratches and worn finish — not deep structural damage
⚠️ Replacement needed when:
→ Treads are pine — softwood that won't hold up long-term
→ Large cracks or splits across the tread
→ Severe structural movement or settling
→ Wood too thin for another sanding pass
→ Tread is damaged beyond cosmetic repair
What we always check first: Before recommending refinish or replace, we assess the full staircase structure — not just the surface. Loose joints, squeaking, settling, low handrails, loose spindles — these are all addressed before cosmetic work begins. A beautiful finish on a structurally compromised staircase won't last.

The Pine Tread Problem in Chicago Homes

This is the most common disappointment we see — and we prepare every client for it before we start.

Many Chicago homes built from the 1960s through the 1990s have pine stair treads hidden under carpet. Homeowners lift a corner, see what looks like wood, and assume it's the same hardwood as their floors. It often isn't. Pine is a softwood — it's 3-4x softer than red oak. After refinishing, pine treads look beautiful for the first few weeks. Then everyday heel strikes, pet nails, and normal foot traffic leave dents and scratches that no amount of finish will prevent.

Our honest recommendation: If your stair treads are pine, we strongly recommend replacing them with red oak before refinishing. The cost difference is significant upfront — but pine treads refinished today will need replacement in 2-3 years anyway. Oak treads refinished properly last 15-20 years. We always show clients both options with pricing so they can make an informed decision.

How to Tell If You Have Pine or Oak Treads

  • Press your thumbnail into the wood — pine dents easily, oak doesn't
  • Look at the grain — pine has a lighter, more uniform grain; oak has a pronounced ray pattern
  • Check existing wear patterns — pine shows dents in the center of the tread; oak shows scratches but holds its shape
  • Ask us — we identify the wood species at the estimate, at no cost

Common Stair Problems in Chicago Bungalows & Greystones

Chicago's older housing stock — bungalows, greystones, two-flats, coach houses — was built under old building codes that had very different requirements than today. Staircases in these homes often reflect the practical realities of the era: builders squeezed staircases wherever they fit, prioritizing space efficiency over safety and comfort.

Stairs Built Under Old Building Code

In many older Chicago bungalows, staircases are steep, narrow, and tucked into corners where space was available — not where it made structural or safety sense. Treads can be shorter than current code allows, risers too high, and handrails at the wrong height. We regularly work with homeowners who have had family members fall on these staircases and finally decide to address the problem properly.

A solution most contractors don't mention: In some Chicago bungalows, there's an opportunity to rebuild the staircase with better proportions — longer treads, safer risers, proper handrail height — by opening a wall, removing a small closet, or reconfiguring the landing. This is more involved than a simple refinish, but it transforms a dangerous staircase into one that's both safe and beautiful. We assess this possibility at every estimate and present it as an option where feasible.

Winder Treads — The Safety Concern

Many older Chicago homes use "winder treads" — triangular or wedge-shaped treads at turns in the staircase instead of a proper landing. Winders save space but create a narrow inside edge where foot placement is dangerous, especially for children and elderly family members. When we rebuild or reconfigure a staircase, eliminating winder treads in favor of a proper landing or longer straight run is one of the most impactful safety improvements we make.

Foundation Settling — A Chicago Reality

Chicago's clay soil causes homes to settle unevenly over decades. In older bungalows and two-flats, this settling shows up in staircases as squeaking, gaps between treads and risers, and doors that no longer close properly. We address settling-related structural issues — adding screws, construction adhesive, and support — before any cosmetic work begins. If we don't fix the movement, the new finish won't last.

Why Chicago Homeowners Replace Carpeted Stairs

Removing carpet from stairs is one of the most popular staircase renovation requests we receive — and it's growing every year. Here's why Chicago homeowners make this decision.

✅ Reasons to remove stair carpet
Cleanliness — carpet traps dust, allergens, pet hair, and odors. Oak treads are wiped clean in seconds.
Home value — oak stair treads consistently increase perceived home value. Real estate agents note it in listings.
Modern look — exposed hardwood stairs with white risers and black iron spindles is the most requested Chicago staircase look in 2026.
Allergies — carpet is one of the largest allergen reservoirs in a home. Removing it from stairs makes a real difference.
Longevity — well-maintained oak treads last decades. Carpet needs replacement every 10-15 years.
🤔 When to keep carpet or add a runner
→ Households with young children or elderly family members who prefer softer surfaces
→ Noise reduction between floors in multi-unit buildings
→ Personal preference for warmth underfoot
Best compromise: a center stair runner with exposed oak borders on both sides — the warmth and safety of carpet with the beauty of hardwood
The stair runner option: Many Chicago homeowners choose a center carpet runner with exposed oak treads on both sides. This gives you the best of both worlds — warmth and slip resistance in the walking zone, beautiful hardwood borders that photograph beautifully for listings. We refinish the oak borders and install the runner as part of the same project.

Structural Issues in Older Chicago Staircases

Before any cosmetic work, we assess and repair the structure. This is what separates a proper stair renovation from a paint job.

  • Loose or missing screws — the most common cause of squeaking. We re-screw treads and risers from below or from the top, depending on access. Learn more about squeaky stair repair.
  • Foundation settling and movement — common in older Chicago bungalows and two-flats. Movement causes treads to shift and squeak. We add construction adhesive and additional support before finishing.
  • Cracked risers — especially in homes with seasonal humidity changes. Cracked risers are replaced before refinishing.
  • Handrails too low — Chicago building code requires handrails at 34-38 inches. Many older homes don't meet this. We raise or replace handrails as part of the renovation.
  • Loose spindles — spindles that rattle or move are a safety issue. We re-secure or replace them as part of the project.
  • Damaged cove molding — the trim piece where the tread meets the riser. Often cracked or missing. We replace it at $30 per tread during the project.
  • Winder treads — where feasible, we eliminate dangerous winder treads in favor of safer configurations.

The Stair Refinishing Process — Step by Step

1
On-site assessment
We inspect every tread, riser, spindle, handrail, and the structural connections underneath. We identify the wood species, assess condition, and give you a clear recommendation — refinish, replace, or both — with pricing for each option. We also assess whether the staircase layout can be improved for safety.
2
Structural repairs
Loose treads and risers are re-screwed and glued. Squeaky connections are addressed. Cracked risers replaced. Handrail height corrected if needed. Loose spindles re-secured or replaced. This happens before any sanding.
3
Tread replacement (if needed)
Pine treads or severely damaged hardwood treads are replaced with new red oak. New cove molding installed at the same time. Risers painted white to match baseboards and trim throughout the home — the Chicago standard.
4
Sanding
Each tread is sanded to bare wood using professional equipment — a Hummel drum sander for the field, an edger for the edges and nosing. Stair sanding is more complex than floor sanding — each tread is an individual surface requiring careful navigation of edges, nosing, and cove molding.
5
Stain matching
Stair treads are stained to match the main floor exactly — same product, same color, applied at the same time when possible. The result is a seamless transition from hardwood floor to staircase that looks intentional, not patched. See our most popular stain colors for Chicago homes.
6
Bona Traffic HD finish
Multiple coats of Bona Traffic HD applied — the same commercial-grade finish we use on every floor project. Low VOC, fast drying, commercial durability. Optional: Bona anti-slip additive for stair treads — gives you the clean hardwood look with added grip for safety.
7
Spindle and railing work
If replacing spindles — wood to black iron square balusters is the most popular upgrade in Chicago right now — this is done after the treads are finished. New newel posts and handrails installed and painted or stained to match the design.

Frequently Asked Questions

How long does stair refinishing take in Chicago?
A typical stair refinishing project (12-16 treads, no tread replacement) takes 2-3 days. Projects involving new tread installation, structural repairs, or spindle replacement take 3-5 days. We give you a specific timeline at the estimate so you can plan accordingly.
Should stair treads match the hardwood floor?
Yes — in Chicago homes, the standard is to match the stair treads to the main floor stain exactly. We use the same stain product and finish on both, applied at the same time when possible. Risers are typically painted white to match the baseboards and painted trim throughout the home. This creates a seamless, cohesive look from the entry to the upper floors.
How do I know if my stair treads are pine or oak?
Press your thumbnail firmly into the tread surface — pine dents easily, oak resists. Look at the grain pattern: oak has a pronounced ray pattern, pine is more uniform and lighter in color. If you have carpet on the stairs, we'll identify the species when we assess the staircase — at no cost. If they're pine, we'll show you both options (refinish vs. replace with oak) with pricing for each.
Are hardwood stairs slippery? Is it safe?
Hardwood stairs can be slippery, especially in socks. We offer two solutions: Bona's anti-slip additive mixed into the final coat of Traffic HD — gives you the clean hardwood look with added grip — or a center stair runner with exposed hardwood borders on both sides. Both are popular in Chicago homes. We discuss the options at the estimate.
What causes stair squeaking in Chicago homes?
Squeaking is caused by movement between the tread and the riser or between the tread and the stringer. In older Chicago bungalows and two-flats, this is often due to the original nails loosening over decades of use, foundation settling from Chicago's clay soil, or seasonal humidity changes causing wood movement. We address squeaking with screws, construction adhesive, and sometimes additional support from below — before any cosmetic work begins.
Can my Chicago bungalow staircase be made safer?
Often yes. Many older Chicago bungalows have staircases built under old codes — steep, narrow, with short treads or dangerous winder steps. In some cases, opening a wall or removing a small closet creates enough space to rebuild the staircase with longer treads, safer risers, and a proper landing instead of winder steps. We assess this possibility at every estimate and present it as an option where the space allows.
How much does it cost to replace wood spindles with black iron in Chicago?
Iron spindle replacement runs approximately $25 per spindle for labor and materials. A typical Chicago staircase has 30-50 spindles, so the spindle replacement portion of a project runs $750–$1,250. This is typically done alongside tread refinishing or replacement for maximum efficiency — one visit, complete transformation.
Can I stay in my home during stair refinishing?
Yes — with Bona Traffic HD (water-based, low VOC), there's minimal smell and no heavy chemical fumes. However, you won't be able to use the staircase while the finish cures — typically 24 hours per coat. For multi-story homes, we plan the work in sections so you always have access to one part of the house. We discuss the logistics at the estimate.
