Hardwood Floor Refinishing Cost (2026): $800–$2,680 per Project

Why does hardwood floor refinishing cost so much?

Most of the price comes down to labor: sanding down the old finish, applying stain if you want one, and building up new topcoats all take skilled hands and time. Sanding alone runs about $0.50 to $3 per square foot, staining adds $1 to $3 per square foot, and finish coats bring the total to a widely cited $3 to $8 per square foot across sources (Fixr, HomeGuide, This Old House, Bob Vila). For a full project, that works out to a typical range of $800 to $2,680, with averages clustering between $1,800 and $1,891 depending on the source and assumed floor size (This Old House, HomeGuide, Bob Vila). Fixr’s lower $1,200 average reflects a smaller sample project size rather than a lower per-square-foot rate — its own per-square-foot figures match the other sources. Method matters too: dustless refinishing, which contains sanding dust with a vacuum rig, costs more per square foot than traditional sanding but saves cleanup time.

What affects the cost?

A handful of factors explain most of the spread between an $800 job and a $2,600+ one:

• Refinishing method. Traditional sand-and-refinish costs $3–$5.50/sq ft; dustless refinishing costs $5–$8/sq ft (Bob Vila, Fixr). A screen-and-recoat that skips sanding entirely costs just $1–$2.50/sq ft (HomeGuide, This Old House).
• Floor size. More square footage means a higher total, though the per-square-foot rate stays roughly consistent across job sizes.
• Wood species. Oak, cherry, and bamboo run about $3–$6/sq ft; maple and mahogany run $5–$8/sq ft, since denser wood takes longer to sand (This Old House).
• Finish type. Oil-based polyurethane is the cheapest topcoat at $20–$50 a gallon; hard wax oil finishes can run $70–$550 a gallon (Fixr, This Old House).
• Staining. Changing or deepening the wood color adds $1–$3/sq ft on top of the base sanding and finish cost.
• Condition of the existing floor. Deep gouges, water damage, or boards that need replacing push a job toward a full sand-down rather than a cheaper recoat.
• Stairs. Priced separately at $25–$45 per step, since stairs take more careful, slower work than open floor area (Fixr).
• Region. Labor rates run $2–$8 per square foot or $60–$160 per hour depending on local market (HomeGuide, Bob Vila).

How to lower your hardwood floor refinishing cost

• Ask if a screen-and-recoat will do. If your floors are scuffed but not gouged or heavily worn, recoating instead of full sanding can cut the cost to $1–$2.50/sq ft instead of $3–$8/sq ft.
• Skip the stain if you’re happy with the current tone. Staining adds $1–$3/sq ft; a clear finish alone is cheaper and faster.
• Choose a standard oil-based or water-based polyurethane. Specialty finishes like hard wax oil can cost more than 10 times as much per gallon.
• Compare traditional and dustless quotes. Dustless costs more per square foot but may be worth it if you’re living in the home during the job; if you can vacate for a couple of days, traditional sanding is the cheaper route.
• Bundle stairs and adjoining rooms into one visit. A single crew mobilization for multiple areas is usually cheaper than separate service calls.
• Get multiple local quotes. Labor alone ranges from $2 to $8 per square foot, so comparing contractors in your area is worth the time before committing.

Prices vary by region, wood condition, and the finish you choose, so treat the figures above as a planning budget. Get two or three local quotes before committing to a final number.
