Stair Tread Replacement — Retro Treads and Risers Over Existing Stairs
The carpet is worn through at the nosings and you want wood stairs to match the new floor. We cap the stair you have or rebuild the treads, one step at a time, and keep it usable each night.
Stair tread replacement is how carpeted stairs become wood stairs. JMB Builders does it across the Twin Cities metro two ways: retro treads, a hardwood cap with the nosing built in that glues and screws over the existing tread with a new riser face under it, or full tread replacement, where the old treads come out and solid hardwood treads go into the stringers. Both get a nosing that matches the flooring. Priced per tread, quoted from photos.

Under most carpeted stairs in the metro is a set of plywood or particleboard treads with a square front edge, screwed to the stringers. They were never meant to be seen. Getting to a wood stair from there means either capping them or replacing them, and which one is right depends on what is under the carpet and how the hall flooring meets the top step.
Retro treads, sometimes called false treads or stair caps, are a piece of hardwood the width of the tread with a nosing milled into the front, thick enough to sit over the existing tread and take a finish. The old carpet, pad, staples and tack strip come off, the old nosing is cut flush, and the cap is glued and screwed down with a new riser face under it. The stair gets taller by the thickness of the cap, which is why the top and bottom step have to be worked out first so the rise stays even.
Full replacement is pulling the old treads and risers off the stringers and installing solid hardwood treads and new risers. It is the right call when the old treads are squeaky, cupped or loose, when the stair has an open side that needs a return on the tread, or when the extra height from a cap would make the top step wrong against the hall floor. Either way the treads are stain-grade oak, maple or hickory to match the floor, and the risers are usually painted.
What you supply
- Photos: the stair from the bottom, the top step at the hall floor, and one step with the carpet peeled back if you can
- The flooring that meets the top of the stairs, or a sample piece, so the treads and nosing match
- Open side or closed: whether the stair has a wall on both sides or a railing side that needs returned treads
- Staining and finishing the treads and painting the risers is quoted as a separate line — or finish them yourself
What JMB supplies

- Retro treads and riser faces in oak, maple or hickory, or solid hardwood treads for a full replacement
- Nosing that matches the hall flooring at the top step, and the transition worked out so the top rise is even
- Treads glued and screwed, screws plugged, returned ends on an open side
- Painted-grade risers in poplar or MDF, primed
- Skirt board scribed or notched to the new treads when the stair needs one
- Staining and finishing when you want it done, quoted as its own line
- Photos of the finished stair in your job folder
How it is priced: per unit
Quoted in writing from your photos within one business day. What moves the number:
- Number of treads, and whether there is a landing or a winder
- Retro treads over the existing stair vs. full replacement into the stringers
- Closed stair vs. an open side that needs returned treads and a rail reset
- Oak, maple or hickory, and matching an unusual flooring color or width
- Old treads that are loose, squeaky or particleboard and need to be fastened or replaced first
- Skirt board added at the same time
- Top-step transition to the hall flooring: a flush nosing vs. a landing tread
Peel back the carpet on one step and send a photo of what is under it, plus a photo of the top step. That tells us cap or replace, and the quote is firm.
How long it takes
Retro treads on a straight run: one to two days, usable each night. Full replacement: two to three days. Staining and finishing is separate and adds drying time.

Situations and options
Retro treads over existing stairs
Carpet off, old nosing cut flush, hardwood caps with a milled nosing glued and screwed down with a new riser face under each. The fastest way from carpet to wood on a closed stair.
Full tread replacement
Old treads and risers off the stringers, solid hardwood treads and new risers in. For loose or cupped treads, open-sided stairs and top steps where a cap would throw the rise off.
Open-side stair with returns
Treads on the railing side get a mitered return nosing on the open end, and the balusters are reset into the new tread. Usually paired with a baluster or newel job.
Wood treads, painted risers
Stained hardwood treads with white painted risers and skirt. The most common look, and the risers can be MDF, which paints smooth and costs less than hardwood.
Stair Tread Replacement — Retro Treads and Risers Over Existing Stairs: questions, answered
Can you replace carpeted stairs with wood?
Yes, and it is the most common stair job we do. The carpet, pad and tack strip come off, and the stair is either capped with hardwood retro treads and new riser faces, or the old treads are pulled and replaced with solid hardwood treads. Which one depends on what is under the carpet and how the top step meets the hall floor. Send a photo with the carpet peeled back on one step and we can tell you.
What are retro treads or false treads?
A hardwood cap the width and depth of a stair tread, with a nosing milled into the front edge, made to install over an existing tread instead of replacing it. The old nosing is cut flush so the cap sits flat, then it is glued and screwed down and a thin riser face goes on under it. They come in oak, maple and hickory and are stain-grade. They add a little height to each step, which has to be planned at the top and bottom so the rise stays even.
Should I cap the treads or replace them?
Cap them when the existing treads are solid and flat, the stair has walls on both sides, and the top step can take the added thickness against the hall floor. Replace them when the treads are loose, squeaky, cupped or particleboard, when the stair has an open side that needs returned treads, or when the cap would make the top rise taller than the rest. Replacement takes longer but leaves nothing to squeak under the new wood.
Will new treads match my hardwood floor?
Close, if we know what the floor is. Treads and retro caps come unfinished in the common species, so oak treads next to an oak floor take the same stain. Send a photo of the flooring or a leftover piece and we match the species and the nosing profile at the top step. Prefinished flooring in an unusual color can be matched by a finisher with a sample.
How do you handle the top step where the stairs meet the floor?
That is the first thing we work out. The top step is a nosing that has to sit flush with the hall floor, so if the stair is being capped, the top gets a flush stair nosing or a landing tread cut to meet the flooring instead of a full cap, and the rise on the top step is checked against the rest. Getting this wrong is what makes a capped stair feel off underfoot, so we measure it before ordering the treads.
Do you stain and finish the new stair treads?
Treads go in unfinished and sanded. Staining and finishing is quoted as a separate line — or finish them yourself. Finishing on a stair means keeping people off it while coats dry, so most customers have us do it or schedule it with their floor finisher. Painted risers go in primed and are painted with the skirt.
