House built in 1978, all hardwood floors, less the kitchen (40 year old vinyl) and baths (tile). No A/C, and no issues with humidity and current hardwood floors over the last 40 years. Want to install pre-finished red or white oak hardwood floor in kitchen, not engineered wood. But manufacturers note humidity must NOT be greater than 70%.
Humidity in NH easily exceeds 70% frequently during Summers.
Is there any way to install the hardwood without future warping, cupping, separation issues, etc. with the floor? I'd really like to go hardwood rather than vinyl, but do not want to spend $1,500 - $2,000, only to find the floor failing a few years in the future.
