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.
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.
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.
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.
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.

Real Stair Projects Across Chicago & Suburbs
Carpet removed from staircase to reveal pine treads — common in Park Ridge homes built in the 1970s-80s. Client initially hoped to refinish but agreed with our recommendation to replace with red oak after seeing the softness of the pine. New oak treads installed, risers painted white, old wood spindles replaced with square black iron spindles and new square newel posts. Structural repairs included re-screwing loose connections and adding adhesive throughout.
1920s greystone with original red oak stair treads in good structural condition — a classic Lincoln Park building. Squeaking throughout the staircase addressed with screwing and adhesive from below before sanding. Treads refinished to match new Bona NaturalSeal main floor. Risers painted white to match the original trim. Original wood spindles retained and painted — client wanted to preserve the traditional character of the original staircase.
North Shore home with significant foundation settling causing movement throughout the staircase — a common issue in Winnetka homes built on Chicago clay soil. Several treads had large cracks from the movement. Full structural assessment performed — new screws, construction adhesive, and additional support added under the staircase. Cracked treads replaced with new oak. Remaining sound treads refinished to match. Handrail height raised to meet current code.
Lakeview two-flat with carpet on the staircase leading to the upper unit. Carpet removed to reveal pine treads underneath — typical for buildings of this era. Client decided to replace with red oak for long-term durability. New oak treads installed with white painted risers and square black iron spindles. The client added a center stair runner for warmth and noise reduction between floors while keeping the oak borders exposed.
Following removal of a chairlift from a 15-foot staircase, several stair planks needed repair due to the screws that were removed. FLOORecki matched the existing stain color, filled the holes structurally, sanded and refinished to blend seamlessly with the surrounding structure. The result matched the existing staircase perfectly — you'd never know the chairlift was there.
