I’m hoping i might get some advice on a recent home improvement project I am working on.
The stairs to our 2nd floor were covered in carpeting. We would like to remove carpet and add Red oak treads.
Upon pulling the carpet off, we discovered the rough treads under the carpet were 2×10 with 3/4 inch risers. There are 2 stringers on either end of the treads. Total span is about 31 inches.
The initial plan was to use a Retro tread product that I could lay over the 2×10 rought treads. However, I have discovered that 3 or 4 of the rough treads are out of level (front to back) by a significant amount (almost 1/4 inch). This was hidden by the carpet and not noticed.
I believe the retrotreads need a level surface to be glued to, so these unlevel rough treads are posing a problem (seems like the stringers on either end of the treads were cut at a slightly different angle from the rest of the cuts).
Given the fact I may need to remove these 3 or 4 unlevel rough treads to get them level, I’m wondering if I can just remove all the rough treads and install standard 1 inch red oak treads?
Would 1x treads be strong enough to replace 2x rough treads? Or would I need to build up the tread by adding 1/2 plywood first with 1x tread on top?
Thanks for your advice!
