Hardwood Floor Refinishing Cost Calculator

A typical ~300 sq ft living area commonly plans around $1,500–$3,600 professionally. DIY materials and rentals often $400–$1,300. Stairs and whole-floor jobs run higher. Enter room sizes for a planning band — not a quote.

Experienced DIYers can, but drum sanders leave permanent waves if mishandled. Hire pros for main living spaces if you have never run a drum sander.

Refinish when boards are solid with enough wear layer. Replace when veneer is too thin, boards are cupped from water, or layout must change. See carpet and LVP calculators for alternate paths.

Assumptions (not a quote): living + dining (~300 sq ft), sand/stain/poly with drum + edger rentals. DIY materials/rentals often ~$400–$1,200. Pro commonly ~$1,500–$3,500. See the local hardwood refinishing market answers.
