I found some hickory engineered flooring that I like. I'd love to put it on the entire main level. My concern is that our stairs railing/posts are oak (and very visible from the main level. The majority is rod iron railings (which we'd keep), but how easy is it to replace the posts and banisters? I thought of staining them but worry the oak will show through and won't match with the flooring. Just trying to budget for this and learn from you guys before purchasing flooring and regretting it later! Thank you!
