Signs your wood floor needs refinishing

By Wood Floor Report Editorial. Last reviewed August 2026. How we research this.

In brief

The four signs, in cost order

Every symptom a wood floor shows lands on one rung of a service ladder. The rungs are priced very differently, and the single question that sorts them is this: is the problem in the finish, or in the wood? Finish problems are cheap. Wood problems are not.

Method: every rate is a national editorial range read at its publisher on August 28, 2026. The $2 to $4.50 screen and recoat rate is our sum of Fixr's two component prices; Fixr does not print the bundled job as one line. Full pricing detail is on the cost hub and the per square foot page.

Sign 1: The floor looks dull, but the finish is intact

Dullness alone is the cheapest problem on this page. If the finish still covers every board, water does not soak in. And the scratches you see are shallow surface scuffs, the wood underneath is fine. The haze is dirt worked into the finish, fine scratching that scatters light, or residue from the wrong cleaning products.

The fix is a cleaning and a buff, or a polish. Buffing runs $1 to $2.50 per square foot. Fixr, Bob Vila. And HomeAdvisor all print that range for the abrade step. And Today's Homeowner prices buffing at $1 to $2.50 as a line item too. No wood is removed. HomeAdvisor describes the machine work plainly: screening "uses a thinner sanding disk to remove the thin topcoat of your floors without affecting the wood beneath."

One warning before you reach for a shine-in-a-bottle product. The Flooring Girl warns that screening "will not work well if you have used products that have wax in them (e.g. mop and glo or orange glo)." A wax-contaminated floor rejects the next coat of polyurethane. That knocks out the cheap maintenance rung entirely. The fold below has the detail.

Sign 2: The finish is worn thin where you walk

Look at the traffic paths: the hallway line, the kitchen sink station, the doorway arcs. If the sheen is gone there while the room edges still shine, the finish is wearing through. The wood is still covered, so this is still a finish problem, and it has a finish-only fix: the screen and recoat.

The job abrades the old finish with a screen on a floor buffer, then lays one fresh coat of polyurethane. Bob Vila's cost guide states the idea in one sentence: "Recoating involves applying polyurethane to the flooring without the extra cost of sanding." The National Wood Flooring Association (NWFA) calls the same job a maintenance coat. It costs $2 to $4.50 per square foot (the sum of Fixr's two component rates), takes one day of work plus 24 hours to dry per The Flooring Girl. And per Inch Calculator costs about half as much as a full refinish.

This rung has a rhythm. The Flooring Girl recommends a screen and recoat about every three years. And says that pace can put off full sanding for a very long time. The arithmetic favors the habit: a floor recoated on that rhythm keeps renewing its wear layer of finish, while a neglected floor reaches HomeAdvisor's refinish cycle, "every seven to 10 years," by wearing down to the wood itself. A recoat spends no wood. A refinish spends 1/32 to 1/16 inch of it per pass, per Just Around the Corner Flooring, against a lifetime budget of about six to eight sandings for a 3/4 inch solid floor. More on that budget at how many times a floor can be refinished.

Sign 3: Bare wood spots or gray boards

This is the line that separates the cheap jobs from the real one. When the finish wears through completely, the exposed wood shows first as a pale, raw patch, then oxidizes gray as air and moisture reach unprotected fibers. Gray is not dirt. It is the wood itself changing, and no new coat on top can undo it.

The Flooring Girl puts gray on the cannot-fix list for a recoat in plain words: "If you have gray patches on the floor, it's too late for a screening." Her full list of what screening will not address runs: deep scratches, changes in color, waxed floors, gray or bare-wood patches. And UV discoloration under area rugs. Any one of those pushes the job up the ladder. Even the chemical recoat systems that replace screening entirely, like Basic Coatings TyKote, draw the same line: the TyKote technical data sheet excludes floors worn through to bare wood, along with floors maintained with paste wax or oil.

The fix is a full sand and refinish: sanding to bare wood with a drum sander and an edger, then new stain if you want it, then two or three coats of finish. NerdWallet prices it at $3 to $8 per square foot, and the same range appears at HomeAdvisor, Bob Vila, Fixr, This Old House, and Inch Calculator. Whole-job averages cluster tightly: HomeAdvisor reports $1,891, Bob Vila $1,869, This Old House $1,800. And Fixr $1,200 on a 200 square foot basis. Changing the color adds staining at $1 to $3 per square foot per HomeAdvisor, for a combined $4 to $11 per NerdWallet's component rates summed. Plan for three to five days of work, per GoFlooring. The full breakdown is on the cost hub.

Sign 4: Damage that sanding cannot erase

Gouges deeper than the sander can reach, black water stains, cupped or crowned boards, squeaking loose boards, pet stains soaked into the wood. And rot are past refinishing alone. These floors need repair first, then a refinish over the repaired surface so old and new boards read as one floor.

The repair bill varies more than any other number on this page. This Old House prices repair pre-work within a refinish at $6 to $12 per square foot. As a standalone job, Fixr reports a $2,000 national average with a $1,000 to $5,000 range, while HomeAdvisor reports $1,077 with a typical $482 to $1,706 range. The spread is honest, so we print both. By problem: scratch repair runs $1 to $8 per square foot per Fixr (HomeAdvisor frames it as $25 to $100 per scratch), water damage $8 to $100 per square foot per Fixr. And rot $50 to $250 per square foot per Fixr. A contained spot repair, replacing boards and blending stain, runs $200 to $500 per Inch Calculator. When damage covers enough of the floor, the honest comparison is refinish or replace.

One safety note that stays visible. If the damaged floor is painted and your home was built before 1978, treat the paint as lead-based until a test says otherwise. The EPA banned lead-based paint for homes in 1978. And homes built before 1940 have an 87 percent chance of containing it, per the EPA. Anyone paid to disturb that paint must be certified in lead-safe work practices under the EPA's RRP rule. Do not dry-sand an old painted floor to see what is under it.

The cost of waiting

The ladder only moves one way. A dull floor buffed this year stays a $1 to $2.50 per square foot problem. A worn traffic path recoated this year is a $2 to $4.50 problem that spends none of the floor's sanding budget. The same path left alone wears to bare wood, goes gray, and becomes a $3 to $8 full refinish, per the six publishers above, that also spends 1/32 to 1/16 inch of the floor's finite wood. Left longer still, open wood takes on moisture and stains. And the job grows a repair line at $6 to $12 per square foot per This Old House.

On a 500 square foot main floor, those rates put a recoat at $1,000 to $2,250 and a full refinish at $1,500 to $4,000, each rate multiplied by the footage. The recoat also resets the clock: done about every three years per The Flooring Girl, it holds the floor above the bare-wood line where the expensive job lives.

Which service does your floor need? A two-question test

Question one: can you see wood problems anywhere? Bare or gray patches, scratches deep enough to catch a fingernail in the wood, black stains, gaps, movement, or a color you want gone. If yes, you are at a full refinish, plus repair first if boards are damaged. Skip to the quote form and describe the worst spot.

Question two: if the wood is fine, is the dullness everywhere or in the traffic paths? Everywhere, evenly, on a floor that still beads its finish: clean it properly, then buff or polish. Concentrated in the walk lines, with the sheen dying there first: screen and recoat, now rather than next year.

Our recommendation, for the reader who is still unsure: book the screen and recoat. It is the rung most tired-looking floors actually need, it is priced at roughly half a refinish per Inch Calculator. And the one real risk of choosing it too early is a floor that merely looks better sooner. The risk of choosing it too late is permanent: once gray shows, the recoat is off the table, per The Flooring Girl. And the price of fixing the floor roughly doubles.

You may not need refinishing at all

Read this before the form. Most floors that look tired fail on dirt, wax haze, or worn finish, not on worn wood. And every one of those has a fix cheaper than the $3 to $8 per square foot refinish this page's search query assumes. A buff runs $1 to $2.50 per square foot. A screen and recoat runs $2 to $4.50. The refinish exists for wood problems: bare patches, gray boards, deep scratches, color changes. If your floor showed none of those in the test above, ask the contractor about the cheaper rung first. And expect a good one to suggest it unprompted. We do not sell flooring and we do not refinish floors. So nothing here rides on which job you book.
