Mopping hardwood floors probably isn't anyone's most favorite chore in the world, but it's not that difficult or time-consuming in the scheme of things. Refinishing those floors, however, is a different story. Sure, you could attempt it yourself, but why? It's back-breaking work, and there's such a small margin of error -- you do run a risk of ruining your floors. So it'd behoove you to call in the pros, sit back, relax and watch your dull floors come back to life.
