Refinish or Replace? How to Tell What Your Floor Needs
Updated August 25, 2026 · 7 min read
A tired hardwood floor gets replaced far more often than it needs to be, and usually for one reason: nobody told the homeowner that refinishing was on the table. Refinishing costs a fraction of a new floor, keeps wood that in an older DMV house is frequently better material than anything sold today, and takes a few days rather than a project. But it is not always possible, and there is a real line between the two. Here is how we work out which side of it a floor is on.
What refinishing actually is
Sanding a floor down past the old finish and any surface damage, then applying stain if you want it and several coats of new finish. Same boards, new surface. The step-by-step of the sanding process covers how that happens.
There is also a lighter version — a screen and recoat, where the existing finish is abraded rather than removed and a fresh coat goes over it. It costs much less, takes a day or two, and it is the right answer surprisingly often. It only works while the finish is still intact; once the wood underneath has been reached, it is a full sand.
Five checks that decide it
1. Is there enough wood left? This is the check that rules refinishing out. A solid floor can be sanded several times over its life, and each pass takes a little wood. Look at a floor register or a doorway threshold — anywhere the board shows in cross-section. If the wearing surface sits close to the top of the tongue and groove, there is not enough left. In a Georgetown or Capitol Hill rowhouse that has been refinished three times already, this is the whole conversation.
2. Is it solid or engineered? Solid hardwood sands many times. Engineered wood is a real wood veneer over a plywood core, and depending on veneer thickness it may take one sanding or none. Sanding through a veneer destroys the board, which is a good reason not to hand the job to whoever is cheapest.
3. Is the damage on the surface or through it? Scratches, dullness, pet marks, faded patches and old yellowed finish are surface problems, and every one of them sands out. Deep gouges, water staining that has gone gray or black, and boards that are cupped or crowned are through-the-surface problems that need addressing before any sanding — see our guide to hardwood floor repair.
4. Is the subfloor sound? A floor that flexes, bounces or squeaks badly has a problem underneath it, and sanding the top does not touch that. Sometimes the right sequence is subfloor work first and refinishing after.
5. Do you actually want this floor? The honest one. Refinishing gives you the same boards in the same width, species and layout. You can change the color completely and the sheen entirely, but a 2¼-inch red oak strip floor refinished is still a 2¼-inch red oak strip floor. If what you want is wide plank, refinishing cannot get you there — that is a new installation.
When refinishing is clearly right
- Solid hardwood with thickness left and cosmetic problems. Scratched, dull, dated color, worn traffic lanes — exactly what sanding is for.
- An older house whose boards beat anything on the market. Old-growth oak and heart pine turn up constantly under carpet in Bethesda, Wheaton, Silver Spring and Hyattsville. That material is not for sale anymore, and covering it is a genuine loss.
- You want a different color. Going lighter, going darker, or moving off a yellowed old finish changes a room as completely as a new floor does — see choosing a stain color.
- The budget matters and the floor is sound. Refinishing is a fraction of installed hardwood, and there is no tear-out or disposal in it. Our refinishing cost guide covers what drives that number.
When replacing is the right call
- The wood is too thin to sand, or it is engineered with too little veneer.
- Water damage over a large area. Isolated boards can be woven in and refinished with the rest; a room that cupped and stayed cupped is usually replacement — and the moisture source has to be found either way.
- Structural or subfloor failure bad enough that the floor is coming up regardless.
- You are changing the floor's character, not its condition. Different species, wider planks, a different direction, or hardwood somewhere it is not currently.
- The room is wrong for wood. Below grade and in wet rooms, hardwood is the wrong material in this climate whatever condition it is in. See waterproof basement flooring.
The middle answer people miss
It does not have to be all one or the other, and the mixed approach is often the best value in the house.
- Refinish the good rooms, replace the bad one. Common where the living areas are fine and one room took water.
- Weave in new boards and refinish everything together. Where damage is confined to a section, new boards lace into the existing floor and the whole floor is sanded and finished as one, so the repair disappears. In a period house we salvage boards from a closet so the visible repair uses wood that aged in the same building.
- Screen and recoat now, full refinish later. If the finish is worn but the wood is untouched, this buys several years for a fraction of the cost and leaves every option open.
What DMV humidity adds
Mid-Atlantic summers are humid and winters are dry, and wood moves with both. Two practical consequences.
First, do not refinish a cupped floor until it has dried and flattened. Sanding a floor that is still holding moisture gives you a floor that goes concave when it finally dries, and the only fix for that is sanding again — which you may not have the thickness for. Our guide to gaps and cupping covers how to tell what your floor is doing.
Second, finish cures more slowly in high humidity, which stretches the time between coats and before furniture goes back. How long refinishing takes has the realistic schedule.
Frequently asked questions
How many times can a hardwood floor be refinished?
A solid hardwood floor can usually take several sandings across its life, because each one removes a small amount of wood. Engineered wood depends entirely on the thickness of the real wood veneer over its core — some allow one sanding, some allow none at all. The only honest way to know is to look at a board in cross-section at a floor vent or a threshold before anything starts.
Is refinishing cheaper than replacing hardwood?
Substantially, on nearly every job. Refinishing keeps the boards you already have and skips tear-out, disposal and new material entirely. The exception is a floor that has to come up anyway for structural or moisture reasons, where refinishing afterwards is not the shorter path.
Can badly scratched or stained floors be saved?
Scratches, dullness, worn traffic lanes, pet marks and sun-faded patches are surface problems and they sand out. What does not sand out is water staining that has gone gray or black through the board, deep gouges, and cupping that has not been dried and flattened first.
What is a screen and recoat?
A light abrasion of the existing finish followed by a fresh coat over the top, with no sanding to bare wood. It costs a fraction of a full refinish and takes a day or two, but it only works while the finish is still intact. Once the wood itself has been reached it is a full sand.
Should I refinish before selling the house?
If the wood is solid and in reasonable condition, refinishing shows extremely well for what it costs, and buyers across the DMV pay a premium for real hardwood. What does not pay is covering sound hardwood with something else — that removes the exact thing buyers were willing to pay extra for.
Most of this is settled in twenty minutes with the floor in front of us — thickness at a vent, solid or engineered, surface damage or structural. It is not settled from a photograph, and it is the single most common thing we are asked to decide.
