Is moisture a concern with solid hardwood flooring over a crawl space?
I had a similar situation with a house redo with a crawl space. This house is near the coast in Maine and both the contractor and flooring company strongly recommended against using tradional wood flooring on the first floor. They were concerned with cupping of the wood. It got to the point where the flooring company - all they do is wood flooring- would not warranty the work unless we used engineered flooring. It was about $1.5 more per foot but it’s been 3 years and have been very happy
