Hello and welcome to the Vaux....
Back in 2013 I had a few sections replaced....my understanding is that the hardwood flooring in Vaux (Spec: Pre-finished, Engineered, Caribbean Rosewood, 9/16" x 3" x RL (1'-7'). I think the product has been discontinued - verify with Decca.
I did not refinish, but did get a quote....I recall this floor can be refinished once (maybe 2x)......
Also, if you replace, you will want to get Vaux COA approval and make sure that any new floor includes Furnish QuietWalk Underlayment Pad.
The original installer was - they are very knowledgable and know the Vaux....good luck!
