I read this in a article from the N.W.F.A. 100 The amount in years (or longer) that a well-cared-for solid wood floor will last with normal wear and tear. If you are on a crawl space or have a basement you should go with a solid floor 100 years is a long time.Remember a solid hardwood floor can be sanded and refinished,carpet has to be removed,and I have never seen a 100 year old laminate floor. Laminate flooring has its place, but it will never replace the beauty or durability of a solid hardwood floor.
