I am looking at refinishing both my wooden banister as well as the hardwood flooring on the main level. The are both identical colors (very light) right now and I want to go a little darker. There are also the same wooden runners going up along the stairs along the carpets. There is also a wooden runner along the wall in the front entrance at about 10 ft high that I want to finish the same color. Any recommendations for this job or is it better just to hire someone?
