Hardwood floor refinishing cost

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

In brief

The cost to sand and refinish hardwood floors, and who publishes it

$3 to $8 per square foot is the most agreed-on number in this trade. NerdWallet, HomeAdvisor, and Bob Vila each publish exactly that range for a professional sand and refinish. This Old House, Fixr, and Inch Calculator print it too. Six publishers, one range, all read August 28, 2026.

Agreement is not precision. On a 500 square foot floor, $3 buys the job for $1,500 and $8 buys it for $4,000. The rest of this page is about which end you land on: the size of the floor, the service level you actually need, the wood, and how much of the work is labor. The per-square-foot page breaks the rate itself down further.

Whole projects cluster tightly across publishers. HomeAdvisor reports a normal range of $1,107 to $2,680 with a national average of $1,891. Bob Vila agrees almost exactly: $1,098 to $2,653, average $1,869. This Old House says $1,800 on average. And Today's Homeowner says most people pay around $2,000, inside a full spread of $300 to $8,000. One planning note: NerdWallet states plainly that "It's almost always cheaper to refinish hardwood floors than to replace them." If you are weighing that choice, start with refinish or replace.

Cost by floor size

Method: each publisher's own cost-by-size table, read at the source on 2026-08-28. NerdWallet's rows are exactly $3 to $8 times the footage. HomeAdvisor's 400 sq ft row implies $2.50 to $6.25 per square foot, dipping below its own $3 floor at the low end. We record it as the page states it.

Two things to read out of that table. First, small jobs do not get small prices in proportion, because setup and machine time are the same whether the room is 40 feet or 100. Second, the two publishers agree within a few hundred dollars at every size. That is rare in home-service pricing and makes these bands unusually safe to plan with. For your own footage, the calculator runs the same published rates.

Cost by service level

This is the decision that moves the most money, and the one a quote rarely explains. There are three different jobs that all get called "refinishing," and they do not cost the same.

Method: all rows read 2026-08-28. The screen and recoat row sums Fixr's screening line ($1 to $2.50) and recoating line ($1 to $2), since Fixr does not price the bundle as one item. The stain row sums the $3 to $8 refinish range and NerdWallet's $1 to $3 staining component. The other rows are published as printed.

Note what the stain row means: changing your floor's color costs $1 to $3 per square foot more than keeping it. And it cannot be done without full sanding. The Flooring Girl, a flooring writer we cite across this site, puts it flatly: to change the color, the floor must be sanded completely down to raw hardwood before stain goes on. The staining page covers what that buys you.

Worked totals at three common sizes

Here is what those service rates come to on real jobs. Same math the calculator runs: floor area times the published rate at each end of the range.

Method: our arithmetic, area times the sourced per-square-foot rates from the service level table above ($2 to $4.50, $3 to $8, and $4 to $11). Stairs, repairs, and furniture moving are extra.

The middle column's middle row is where most quotes land. Inch Calculator says a typical whole project runs $1,000 to $2,500. Its own worked example prices a 300 square foot room at $1,200, which is $4 per square foot. Say a quote for a sound, unstained 500 square foot floor comes in well above $4,000. The first question to ask is which service level it is pricing.

Cost by wood species

Method: costs are NerdWallet's cost-by-wood-type list, read 2026-08-28. Hardness figures are 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 tables do not carry a flooring product, we say so instead of borrowing a number.

Hardness is not the whole story, and the table shows it. Pine is the softest wood listed at 380 lbf, yet it costs more to refinish than oak. 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 for two reasons: it is harder than oak, and it stains badly. The Maple Flooring Manufacturers Association itself says much of a stained maple surface will look uneven and blotchy. More on all of this at wood species.

What each component costs

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

Materials are the small end of these numbers. Today's Homeowner prices the topcoat itself at $25 to $50 per gallon for water-based polyurethane and $20 to $40 for oil-based. A gallon covers hundreds of square feet. That is why the component costs are mostly labor wearing a materials label.

Labor: most of what you pay

HomeAdvisor says labor can run up to 80 percent of the total project price. And This Old House prints the same 80 percent figure independently. The rate behind it: $2 to $8 per square foot, or $60 to $160 per hour, published identically by HomeAdvisor, Bob Vila, and Today's Homeowner. Bob Vila adds the pace, about five hours to refinish 100 square feet, which is how an hourly rate becomes a per-foot rate.

Fixr gives the cleanest worked example: in its $1,200 average job, about $700 is labor. That is 58 percent, our arithmetic on Fixr's two published figures. So when two quotes for the same floor differ by thousands, you are mostly comparing two crews' time, skill, and equipment, not two piles of polyurethane.

The dustless premium

Dustless refinishing costs about $2 more per square foot, per HomeAdvisor. That lifts the standard range to $5 to $8. Bob Vila publishes the same $5 to $8 dustless range. And Fixr prices the method at $6 to $8 against $3 to $5.50 for standard sanding.

What the premium buys: a vacuum system attached directly to the sanders, capturing dust where the machine cuts. Its HEPA filter traps 99.97 percent of 0.3 micron particles. That spec comes from Northwest Hardwood Flooring, a refinishing contractor, and we checked it against the equipment specs. It is not literally dust free: capture runs 95 to 99 percent. The practical difference is cleanup. The same source puts it at one to two hours of light cleaning after a dustless job, against days of dust settling after a traditional one.

You may not need a full refinish

Here is the part of this page that saves the most money. A large share of floors priced for a full refinish do not need one. If your finish is dull and scratched 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. On the recoat itself, Fixr's line is $1 to $2 per square foot. And Inch Calculator puts a recoat at about half the cost of a full refinish. On a 500 square foot floor, the published rates make that the difference between roughly $1,000 to $2,250 and $1,500 to $4,000, area times rate at each end.

The screen and recoat has hard limits. And The Flooring Girl lists them plainly: it will not fix deep scratches, will not change the color, will not rescue wood that has grayed from oxidation or sunlight marks under rugs. And will not bond over wax or wax-containing polishes. Any of those pushes you back to the full sand. But if none of them apply, done about every three years, a screen and recoat keeps postponing the expensive job. The full walkthrough is at screen and recoat, and the symptom checklist at signs you need refinishing.

We can say this without hedging because we do not sell flooring and we do not refinish floors. The site connects homeowners with licensed contractors. The cheaper job costs us a bigger lead and we recommend it anyway when it fits.

Which service your floor needs

Method: service rates as sourced in the tables above. Repair pre-work is This Old House's $6 to $12 per square foot for fixing deep scratches, gouges, and loose boards before refinishing begins. The engineered row uses Fixr's recoat rate. All read 2026-08-28.

Our recommendation, plainly: if your floor has no bare wood, no color change planned, and no wax history, ask contractors to quote a screen and recoat first and make them argue you up, not down. If damage is why you are here, price the repair before the refinish, because it stacks on top. That math lives at wood floor repair cost. And if your floor is engineered, check the wear layer before anyone starts a sander. The National Wood Flooring Association's rule: below 2.5 mm of wear layer, do not sand at all. The test and the exceptions are at engineered hardwood.

The cost over the floor's life

One more way to read these prices: as a schedule, not a one-time bill. HomeAdvisor says to plan on refinishing every seven to 10 years. A 3/4 inch solid hardwood floor can take about six to eight full sandings over its service life, per Just Around the Corner Flooring, so the floor under you is likely to outlive several finishes. The cheap move compounds: a screen and recoat about every three years, per The Flooring Girl, keeps the finish ahead of the wear and pushes the next $3 to $8 per square foot sanding years further out, at $2 to $4.50 each time. Floors that get this treatment spend more years looking finished and lose less wood to sanders. The count and its limits are at how many times can floors be refinished.

One safety note that never gets folded

If you or your contractor use an oil-based finish, the used rags can catch fire by themselves. Drying oils release heat as they oxidize, and a piled rag traps that heat until it ignites. The NFPA counts an average of 900 US home fires a year started by oily rags. Its rule: never pile used rags. Dry them spread out or hung outdoors, away from the building, then seal them in a metal container filled with water and detergent solution. Water-based finishes do not self-ignite this way, per the same NFPA sheet.
