Your home is beautiful. I think it'd look nicer matched color-wise to the parquet. Does it attach to the kitchen as well though? I actually really like the parquet - I have a small landing with parquet but it's oak that lightened over the years was wondering about refreshing it & making it a bit darker. Is yours old original parquet & have you ever done that?

We have hardwood on our main floor and LVP on our stairs down to the basement as well as on the basement floor (over cement). When the LVP was first installed on the stairs (it's been a little over a year now), my husband thought the "lip" part of the stair treads (the bull-nosed edge piece) was not installed perfectly flush and secure on several (I think 4) of the treads, so I wonder if that is not uncommon and is what your flooring contractor is worried about. I didn't even notice it, but my husband is a perfectionist and it bothered him. Rather than complain and have the installers come back to address the issue, my husband fixed the issue himself. I think he used tiny little nails (with no heads) to better secure the edge pieces to the adjoining LVP pieces, and I used dots of acrylic paint from my art supplies to cover the bitty nail holes. We have never had a problem with them since and we are up and down the stairs many times daily so they get heavy use. Just wanted to mention our experience in case that makes any difference for your decision. I don't regret using it on our stairs. We picked an LVP that coordinates pretty well with our upstairs hardwood in color, just a little more rustic which fits our basement vibe. We didn't want to introduce yet another type of flooring just for the stairs.

@ Patricia Thanks, that’s helpful. I see that Pax attaches to the wall but my thinking was that it still rests on the floor, I think? With that in mind, if we install the closet system before the floor, my thinking was that we would not install new floor under the closet boxes. - it’d just be bare. Is that considered acceptable? We’re not looking to resell, just don’t want to mess things up.

They definitely should blend if you can't match exactly. The old floors look like oak and the same width as the new. We had the same issue--the old oak floors are almost 100 years old, not sure what kind of oak, the new white oak about 10 years. Both stained special walnut. Here is where they meet--can you tell which is which?
