Refinishing hardwood floors: cost per square foot

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

In brief

The $3 to $8 consensus, and who publishes it

Method: each publisher's own refinishing cost page, read at the source on 2026-08-28. The implied rates in the notes column are our division of a publisher's printed totals by its printed footage.

No home-improvement price is published more consistently than this one. Six mainstream cost guides land on $3 to $8 per square foot for a professional sand and refinish. Read the agreement carefully, though. Six identical ranges does not mean six independent surveys. Cost guides read each other, and none shows its raw data. What the consensus does give you is the language of the trade: a contractor bidding your floor expects to land inside $3 to $8. And a bid far outside it should come with a reason you can ask about.

The width is the real information. On a 500 square foot floor, $3 per square foot is a $1,500 job and $8 is a $4,000 job, footage times the rate. Homewyse shows why the band is that wide. Its $6.49 to $7.92, dated May 2026, prices one defined scope: prep, two-pass machine sanding, and two coats of polyurethane. Everyone else's $3 covers a lighter job than everyone else's $8. The rest of this page is about which end your floor sits on.

Where the tables contradict themselves

NerdWallet's cost-by-size table is exactly its rate times the footage: 40 square feet at $120 to $320, 100 at $300 to $800, 400 at $1,200 to $3,200. And 1,000 at $3,000 to $8,000. Clean arithmetic, nothing learned.

HomeAdvisor's table is more useful because it is not clean. Its 400 square foot row reads $1,000 to $2,500. Divide $1,000 by 400 and the low end is $2.50 per square foot, 50 cents below the $3 floor the very same page states as its average. That is not our estimate. It is HomeAdvisor's own table read against HomeAdvisor's own rate, 2026-08-28. And we print the quirk rather than smooth it over. Today's Homeowner stretches further the same way: its 3,000 square foot row reads $6,000 to $8,000, an implied $2 to $2.67 per square foot. The pattern behind both is that big floors get quoted below the advertised floor, because the fixed work spreads thin. Treat any per-foot rate as a planning band, not a law, and treat the bottom of the band as something large floors earn.

Method: our division, each row's printed total over its printed footage, both read at the source 2026-08-28.

Per square foot by service level

"Refinishing" is three different jobs wearing one name, and the rate roughly doubles at each step up the ladder. This is the fastest way to misread a quote, or to catch one misreading you.

Method: all rows read 2026-08-28. The screen and recoat row sums Fixr's screening line ($1 to $2.50) and its recoating line ($1 to $2). The reason: Fixr does not price the bundle as one item. The stain row sums the $3 to $8 refinish consensus and NerdWallet's $1 to $3 staining line. Every other row is as printed at the named source.

Two boundaries on the ladder do most of the work. A recoat cannot fix scratches that reach bare wood. And nothing short of full sanding can change the color: The Flooring Girl states flatly that a color change means sanding down to raw hardwood before stain goes on. Dustless is the same full refinish with vacuum capture at the sander. And HomeAdvisor prices that premium at about $2 per square foot. Whether it is worth paying is covered at dustless refinishing. Parquet, note, sits inside the normal band rather than at a premium, with HomeAdvisor pricing its sanding at $3 to $5. The pattern-floor detail is at parquet floors.

Two add-ons ride on top of any rung. Damage repair comes first: This Old House prices fixing deep scratches, gouges, and loose boards at $6 to $12 per square foot before refinishing begins. And the full damage math is at wood floor repair cost. Stairs price by the step as often as by the foot, $25 to $45 per step at Fixr and $25 to $85 at Bob Vila, against HomeAdvisor's $4.50 to $8 per square foot. That trade has its own page at stair refinishing cost.

Per square foot by wood species

Method: costs are NerdWallet's cost-by-wood-type list, read 2026-08-28. Hardness is Janka side hardness at 12 percent moisture content, from the USDA Forest Products Laboratory's Wood Handbook (FPL-GTR-282, chapter 5). Where the handbook does not carry a product, the cell says so instead of borrowing a number.

The table's lesson is that hardness does not set the rate. Pine sits at 380 lbf, the softest wood listed. And still costs more to refinish than oak at 1,290 to 1,360. Ben Osborne of How To Sand A Floor explains why: pine is fibrous and resilient. So it sands as hard as oak despite being softer. Maple tops the price list because of stain, not strength. The Maple Flooring Manufacturers Association itself warns that much of a stained maple surface will look uneven and blotchy. So a maple job involving color takes more skill and more passes. Species behavior in full is at wood species.

The component stack: how the rate is built

Method: each publisher's own component line items, read 2026-08-28. The cross-agreements were checked at each named source, not assumed.

Stack the three lines of a stained refinish, sanding plus staining plus recoating. And you get $2.50 to $8 per square foot, our addition. That nearly rebuilds the $3 to $8 headline, which is a useful sanity check: the consensus is close to the sum of its own parts. Do not expect the numbers to reconcile exactly. These are survey averages, not an invoice, and a real job carries two or three finish coats. What the sanding line buys is a drum sander run across the field of the floor, starting at 36 or 40 grit per Ben Osborne. And an edger along the walls.

Materials are almost noise inside these lines. Today's Homeowner prices the topcoat itself at $25 to $50 per gallon for water-based polyurethane and $20 to $40 for oil-based. At retail, a gallon of DuraSeal oil-based polyurethane sells for $52.61 to $53.40 at Floor Mechanics and covers about 500 square feet per its product sheet. That works out to about 11 cents per square foot per coat, our division. Bona Mega, a water-based finish, is $93.19 per gallon covering 500 to 600 square feet: about 16 to 19 cents. Nearly all the distance between that and the $3 to $8 you pay is labor, machines, and overhead.

Labor: the rate inside the rate

Three publishers print the same labor figure, identically: $2 to $8 per square foot, or $60 to $160 per hour, at HomeAdvisor, Bob Vila, and Today's Homeowner. HomeAdvisor says labor can reach 80 percent of the project price. And This Old House prints the same 80 percent on its own. Fixr runs lower at $2 to $5 per square foot and gives the cleanest worked case: $700 of its $1,200 average job is labor. That is 58 percent by our division. Inch Calculator says $3 to $5.

The hourly rate and the per-foot rate are the same fact in two units. Bob Vila's pace figure is about five hours to refinish 100 square feet. Multiply $60 to $160 per hour by five hours per 100 square feet and you get $3 to $8 per square foot, our arithmetic. The headline range rebuilds itself from two separately published numbers. And that agreement is the best evidence on this page that the consensus describes something real.

Why small floors cost more per square foot

The publishers agree on the rate and scatter on the small job. Here is the same 40 square foot hallway at three of them.

Method: each publisher's cost-by-size table, read 2026-08-28. The implied rate is our division, the printed total over 40 square feet.

The low ends run from $80 to $300 for the identical hallway. Today's Homeowner's implied rate reaches nearly double the consensus ceiling. That scatter is the fingerprint of fixed costs and minimum charges: the work that does not shrink with the room. A crew refinishing 40 square feet still loads the drum sander and the edger. It still masks the doorways, drives out, and returns for finish coats. At Bob Vila's pace of five hours per 100 square feet, the hallway is about two hours of machine time. At the published $60 to $160 per hour, that is $120 to $320 of labor alone, our multiplication. Labor by itself clears HomeAdvisor's $80 low end before a drop of finish. The practical reading: below a room or two, stop dividing by footage.

Price the visit by the hour, expect the per-foot number to look high. And bundle small areas into one appointment, because the second room shares the setup the first one paid for.

The verdict: which rate to multiply

Find your floor in the left column and multiply your footage by the band. A quote outside that math is a question to ask, not proof of a bad contractor.

Method: the service, species, and labor rates sourced in the tables above, arranged as a decision table. All read 2026-08-28.

Our recommendation, plainly: run your footage times both ends of your band before anyone visits. If the floor qualifies for a screen and recoat, get that quoted first. Make the contractor argue you up the ladder, not down. On a 500 square foot main floor, the gap is real money. A screen and recoat runs $1,000 to $2,250. A full refinish runs $1,500 to $4,000. Both are footage times each published rate. The calculator runs these same rates on your own numbers. The whole-project view, size tables and all, is on the cost guide.

You may not need the $3 to $8 job

The most expensive mistake this page can prevent is paying the full-refinish rate for a floor that needs the cheap rung. If your finish is dull but the scratches do not reach bare wood, the floor has never been waxed. And you like the color, the right job is a screen and recoat at $2 to $4.50 per square foot, not a sand and refinish at $3 to $8. Inch Calculator puts a recoat at about half the cost of a full refinish. The limits are real, and The Flooring Girl lists them: it will not fix deep scratches, will not change the color, will not rescue wood grayed by oxidation or sun-marked under rugs. And will not bond over wax. If none of those apply, take the cheaper job. The walkthrough is at screen and recoat.

One floor type should be pushed down the ladder, never up. If your floor is engineered, the National Wood Flooring Association's published rule is that a wear layer under 2.5 millimeters (3/32 inch) should not be sanded at all. And the $1 to $2 recoat rate is the only refresh such a floor will ever take. Check the wear layer before any sander starts. How to check is at engineered hardwood.

We can say all this without hedging because we do not sell flooring and we do not refinish floors. This site connects homeowners with licensed contractors. Recommending the cheaper job costs us the bigger lead. And it is still the right call when the floor qualifies.
