Removing carpet from stairs and replacing with hardwood is one of the most dramatic transformations you can make in a Chicago home. It's also one of the most unpredictable — because what's under that carpet is often not what homeowners expect. After 18 years doing this across Chicago and suburbs, here's exactly what to expect.

What's Actually Under Your Stair Carpet in Chicago

The most common question: is there real hardwood under my stair carpet? The answer depends heavily on when and how your home was built.

Home TypeWhat's typically under stair carpet
Pre-1960s Chicago bungalows, greystones, two-flatsAlmost always original hardwood treads — usually red oak. Often refinishable if structurally sound.
1960s–1990s constructionOften pine — a soft raw carpentry material used as the structural tread with carpet expected to cover it permanently. Needs replacement with oak.
Prefabricated / builder-grade staircasesPine treads in a prefab system — often no separate risers, just skirtboards with routed channels. Treads replaceable but requires adding a stringer underneath.
New construction (post-2000)Usually pine or MDF — designed for carpet. New oak treads required.
The honest reality: In most Chicago homes with carpeted stairs — especially those built after 1960 — the treads under the carpet are pine or raw carpentry-grade material that was never meant to be seen. The carpet was the finish. When homeowners lift the carpet expecting hardwood, they often find soft pine that needs full replacement before anything can be refinished or finished properly.

The Pine Tread Problem — Chicago's Most Common Surprise

Pine is a softwood — significantly softer than red oak. It was commonly used as a structural material in staircase construction in Chicago homes built from the 1960s onward, with the assumption that carpet would permanently cover it. When we remove that carpet, here's what we find:

  • Raw, unfinished pine — sometimes never treated or primed. Just structural lumber used as a tread.
  • Visible nail holes and construction marks — from the original installation and subsequent carpet tack strips.
  • Soft surface — pine dents with even light pressure. A thumbnail pressed into pine leaves a visible mark. Oak resists this completely.
  • No moisture resistance — pine absorbs stain unevenly and doesn't hold finish the same way hardwood does.
Can we refinish pine treads? Technically yes — but we strongly recommend against it. Pine looks acceptable for a few weeks after refinishing. Then everyday heel strikes, pet nails, and foot traffic leave permanent dents and scratches. We've refinished pine treads at client request and had them call us back within a year asking to replace with oak. We always present both options with pricing — and we always recommend oak.

Prefabricated Staircases — What They Are and What We Do

This is something most homeowners — and many contractors — have never heard of. But we see it regularly in Chicago homes built from the 1980s onward, and it's important to understand before any work begins.

What is a prefabricated staircase?

A prefabricated staircase is a factory-built system where the structural components — the skirtboards (the angled boards on either side of the staircase) — have channels routed into them. The pine treads sit in these channels rather than being attached to traditional stringers. Critically, many prefabricated staircases have no separate risers — just the skirtboard channels holding the tread in position.

Why this matters for replacement: When we remove pine treads from a prefabricated staircase, we can absolutely replace them with new red oak treads — but we need to add a stringer (the support structure that runs underneath each tread) to properly support the new hardwood. Without this additional support, the new treads won't be structurally sound. We identify prefabricated staircases at the estimate and include the stringer installation in the quote.

How we handle prefabricated staircases

  • Remove existing pine treads from the skirtboard channels
  • Add stringer (support structure) under each tread position — this is the critical step that makes the new treads structurally sound
  • Install new red oak treads — properly supported and secured
  • Add risers if needed — many prefab systems had no risers; we add them as part of the renovation for a complete, finished look
  • Sand, stain, and finish with Bona Traffic HD to match the main floor
Our approach: We assess whether your staircase is traditional or prefabricated at the estimate — before any carpet comes up. When it's a prefab system, we explain exactly what's involved and give you a complete quote that includes the stringer installation. No surprises after the carpet comes off.

The Process — Step by Step

1
On-site assessment
We lift the carpet at multiple points — not just one corner — to identify the tread material, staircase construction type (traditional vs. prefabricated), and structural condition. We check for squeaking, settling, and any safety issues. This determines the full scope and cost of the project.
2
Carpet and tack strip removal
Carpet, padding, and tack strips removed from every tread and riser. Staples and remaining debris cleaned from the tread surface. Included in the project cost.
3
Structural assessment and repairs
Any squeaking, loose connections, or structural issues addressed before cosmetic work begins. For prefabricated staircases, stringer installation done at this stage to properly support new treads.
4
Tread replacement (oak)
Pine treads removed and replaced with new red oak treads — the right material for a staircase that will be finished and exposed. New cove molding installed. For prefabricated systems, stringer added before new treads are secured.
5
Risers — painted white
Risers painted white — the Chicago standard that matches baseboards and painted trim throughout the home. For prefab systems without risers, new risers added and painted. The white riser + oak tread combination is the most requested look in Chicago in 2026.
6
Sand, stain, and finish
New oak treads sanded, stained to match the main floor, and finished with Bona Traffic HD. Same product, same color as your hardwood floors — a seamless transition from the entry up the staircase.
7
Spindle update (optional)
Many clients upgrade spindles at the same time — replacing dated wood spindles with square black iron balusters. This is the most popular staircase upgrade in Chicago right now and is done after treads are finished and cured.

Should You Add a Stair Runner?

One of the most popular options for carpeted stair conversions in Chicago is a center stair runner — a strip of carpet down the middle of each tread, with exposed oak on both sides.

✅ Stair runner makes sense when:
→ Household has young children or elderly family members
→ Multi-unit building — noise reduction between floors
→ Safety concern about slip on hardwood
→ Want warmth underfoot in bedrooms above
→ Love the mixed look — carpet center + oak borders
✅ Full hardwood makes sense when:
→ Clean, minimal look is the priority
→ Selling the home — full hardwood photographs better
→ Allergy concerns — no carpet anywhere
→ Using Bona anti-slip finish for safety
→ Want zero maintenance long-term
Bona anti-slip finish: If slip safety is your main concern but you want the full hardwood look, we apply Bona's anti-slip additive to the final coat of Bona Traffic HD on the stair treads. This gives you the clean hardwood aesthetic with significantly improved grip — no runner needed. We discuss this option at every stair project.

Frequently Asked Questions

What is usually under stair carpet in Chicago homes?
In older Chicago homes (pre-1960s bungalows, greystones, two-flats), it's often original red oak hardwood that can be refinished. In homes built from the 1960s-1990s, it's usually pine — a soft raw carpentry material that was designed to be permanently covered by carpet. In prefabricated staircases common in suburban construction, it's pine treads in a channel system with no separate risers. We identify the exact construction type at the estimate.
Can pine stair treads be refinished?
Technically yes, but we strongly recommend against it. Pine is too soft for exposed stair use — heel strikes, pet nails, and everyday foot traffic leave permanent dents within weeks of refinishing. We always present both options (refinish pine vs. replace with oak) with pricing, and we always recommend oak for long-term results. Oak treads refinished properly last 15-20 years.
What is a prefabricated staircase and can it be converted to hardwood?
A prefabricated staircase is a factory-built system where pine treads sit in channels routed into the skirtboards, often with no separate risers. Yes, it can absolutely be converted to hardwood — but it requires adding a stringer (support structure) underneath the new treads before installation. We identify prefab staircases at the estimate and include the stringer installation in the quote. Many contractors miss this step and the result is an unsupported, unstable staircase.
Should stair treads match the hardwood floors?
Yes — in Chicago homes, the standard is to match the stair treads to the main floor stain exactly. We use the same stain and finish on both, applied at the same time when possible. Risers are painted white to match the baseboards and trim throughout the home. This creates a seamless, cohesive look from the entry to the upper floors.
How long does carpet to hardwood stair conversion take?
A standard conversion with new oak treads typically takes 3-4 days including carpet removal, structural work, tread installation, painting risers, and finishing. Projects involving prefabricated staircase stringer installation or iron spindle replacement may take 4-5 days. We give you a specific timeline at the estimate.
Are hardwood stairs slippery without carpet?
They can be, especially in socks. We offer two solutions: Bona anti-slip additive in the final coat of Traffic HD (gives you the full hardwood look with improved grip), or a center stair runner with exposed oak borders on both sides. Both are popular in Chicago homes. If safety is a concern, we discuss which option makes more sense for your household at the estimate.
