The formula

Cost = area x base rate x condition multiplier + stain + stairs

Water-based finishes cure faster and smell less but cost about 25% more than oil-based polyurethane.

Worked example

Refinishing 900 sq ft of oak with a stain color runs about $4,300 to $6,100.

Frequently asked questions

How much does it cost to refinish hardwood floors?

Most projects run $3.50 to $7.00 per square foot in 2026, or roughly $1,800 to $4,500 for a typical main floor.

Refinish or replace?

If the boards are at least 3/4 inch thick and structurally sound, refinishing costs about a third of replacement and lasts 8 to 12 years.
