I have a rule about old wood floors: before you tear anything out, find out what you already have. Under decades of scratched, cloudy finish there is almost always good wood waiting for a second life, and refinishing is the cheapest dramatic change you can make to a room. The only real question is how far down you need to go to get there. That is the whole sanding versus sandless conversation, and I make this call on projects all the time.
Full sanding: the honest reset
Sanding takes the floor back to raw wood. A drum or belt sander lifts off the top layer, the old finish goes with it, and you are left with a clean surface to stain and seal however you like. It is the method I reach for when a floor has real problems: deep scratches, gouges, water marks, boards that have gone three different colors over the years, or a stain I simply do not want to live with anymore.
This is also the only way to change the color of a floor with any integrity. If you want to take a builder-orange oak and walk it toward something softer and more European, you have to get down to bare wood first. The process moves through grits, coarse to fine, and a good crew keeps the sanding even so the boards read as one continuous plane. It is dustier and more disruptive, but it buys you the most durable, longest-lasting result. On a floor I plan to keep for twenty years, that trade is easy.
Sandless refinishing: a refresh, not a reset
Sandless refinishing skips the demolition. Instead of removing wood, the floor is cleaned, lightly buffed to open up the existing finish, and given a fresh top coat. Done on the right floor, it brings back the depth and sheen in an afternoon with almost no mess.
The catch is that it can only work with what is already there. A buff-and-coat will not erase a deep scratch, level an uneven board, or change your stain color. It is a refresh for a floor that is fundamentally in good shape and just looks tired. I lean on it in rental turns, quick refreshes before a party, or a house where the floors are honestly fine and the budget is better spent elsewhere.
How I actually decide
My shorthand is simple. If the damage is cosmetic and shallow, or the color is already right, sandless does the job for a fraction of the cost and chaos. If the floor is genuinely worn, uneven, or the wrong color, sand it properly and do it once. Wood species matters too. A hard oak forgives an aggressive sanding; a softer pine has less material to give, so I am gentler with it and lean toward sandless when I can.
One thing I tell every client: the finish you choose changes the whole mood of the room. A matte or satin seal reads quiet and modern and hides foot traffic. A higher sheen throws more light and feels a little more formal, a little more glamorous. Neither is right or wrong, but it should be a decision, not a default.
The part most people skip: what goes on top
Here is where I get opinionated. People spend weeks agonizing over stain color and then drop a random rug on the finished floor, and it undoes all of it. A refinished wood floor is a backdrop. It is supposed to make the furniture and the rug look better, and the rug is what actually sets the tone of the room.
On a warm, freshly sanded floor I love the tension of a cool, graphic wool on top. A flatweave from our Color Study collection keeps things low and architectural and lets the grain show around the edges. When a room wants more softness and depth, I go to one of our original luxury wool designs and let the pattern do the talking. Old things look better with new things next to them, and a beautiful floor is no different. It needs a little contrast to come alive.

The short version
Sand when the floor has real damage or the wrong color, and treat it as a once-in-a-generation reset. Choose sandless when the floor is sound and just needs its shine back. Then spend your energy on the finish sheen and the rug, because that is what people actually feel when they walk into the room. Restored well, a wood floor is one of the few things in a house that gets better with age.
