My wife and I are having hardwood floors installed in a new condo currently under construction. We like the look of Maple floors and understand that there is a premium for Maple when compared to Oak. However, we've heard some negative reports from some folks regarding Maple and its durability, resistance to warping from heat, humidity changes etc. One couple even told us they spilled red wine on their new maple floors and permanently stained the wood. Would like to hear if there are any issues to consider between oak and maple hardwood floors besides the higher price for Maple?
