Anything I have listed is durable. By durable, I mean that anything I offer should last well over a hundred years, as long as you don’t flood it or set it on fire! Is that durable enough? That it will outlive your children and possibly their children?
Pine was used exclusively for the first several hundred years of colonization on this continent – many of those floors still survive – and, don’t you think those floors saw children and dogs and who knows what else over those centuries? When did it suddenly become accepted that wood flooring (of ANY species) isn’t “durable” enough?? Besides stone or dirt, it’s the most durable flooring option available. Don’t let anyone convince you otherwise!
