We installed luxury vinyl tile in our kitchen and landing, which replaced 25 year old laminate. The landing was the only place that didn't have quarter inch plywood under the laminate. Our handyman installed new quarter inch plywood on all the floors before installing the vinyl tile. The landing is now about a half inch taller. As a result, there is a half inch gap from the top of the carpet on the stairs to the stair transition. We plan to get a new stair transition, but there will still be a gap. How should we fix this? Is there something that can go between the carpet and transition that will look good? The distance from the top of the carpet to the top of the vinyl tile is 2 inches.
This is more a design question than anything, but here's my $.03. I don't like brass strips. They smack of mobile homes and RVs--cheap and lazy. I like either wood or coordinating components. My hunch is that your flooring manufacturer offers such parts. So start by looking for those.
If that falls through, consider making one out of the same wood and finish we see in your base trim, or replace the carpet with a plywood finish riser to match. You could also install a wooden pacer above the carpet, and install your metal nosing over that.
For the easiest fix of all, nail a flat brass transition over the carpet edge, then reinstall your current brass nosing.
