I have hardwood floor on the main level of my home and I am thinking about installing it on the 2nd floor. Do you recommend it?
Oh, yes, but you might consider that hardwood floor being a solid surface, is not so good on the wear and tear of your knee joints. So while I have hardwood floors throughout all of my house, I also minimize my knee joint damage by adding lots of area rugs. And consider runners down the halls. At least the area carpets will last a long time and can be easily removed to clean.
