Carpet to Solid Hardwood Tread Conversion in Los Angeles
About This Project
Homeowners usually assume there is a finished wooden stair hiding under the carpet. There almost never is. On a builder-grade stair the treads are construction-grade plywood or unfinished pine, never intended to be seen, and often notched and shimmed to get the rise consistent.
This Los Angeles home was exactly that. Rather than attempt to refinish what was there, we capped it — a solid oak tread cap over the existing structure, with new solid risers. Capping keeps the existing stair carcass and its established rise and run, which matters because rebuilding the carcass means re-permitting the stair geometry in most LA jurisdictions.
What the Homeowner Needed
Replace worn stair carpet with hardwood, without rebuilding the stair or triggering a geometry re-permit.
Challenges on Site
The existing rise varied by nearly 3/8" between steps, which is within tolerance for a carpeted stair but visible on exposed hardwood. Each cap was individually thicknessed to bring the finished rise into a consistent dimension.
How We Solved It
Solid oak capping over the retained carcass, with each cap individually thicknessed to even out the inherited rise variation.
Project Highlights
- ✓ No structural rebuild or re-permit
- ✓ Rise variation corrected in the caps
- ✓ Original stair geometry retained
Common Questions
Is there hardwood under my stair carpet?
Usually not. Builder-grade stairs use construction plywood or unfinished pine for treads because they were never meant to be seen. Pull back a corner at the top step before assuming a refinish is possible.
Does capping stairs reduce headroom or change the rise?
Capping adds material to each tread, so the top step gains height unless it is accounted for. A competent installer thicknesses the caps to keep the rise consistent — otherwise you end up with one noticeably shallow step at the top, which is both odd underfoot and a code issue.
Project Overview
The most common stair project we do, and the one with the most misconceptions about what is underneath.
Materials & Details
- Solid White Oak Tread Caps
- Poplar Risers
- Existing Carcass Retained
We thought we would find a nice wooden staircase under the carpet. We did not. They explained the options honestly instead of just quoting a refinish.
