Hardwood Floor Refinishing Cost: Pricing Guide

Hardwood floor refinishing costs $3 to $8 per square foot depending on the scope of work, finish type, and floor condition. For a typical 500 square foot living area, expect to pay $1,500 to $4,000 for a professional refinish.

Average Refinishing Costs by Scope

The scope of your refinishing project is the primary cost driver. A basic sand-and-seal is significantly less than a full refinish with stain changes.

Basic Sand and Seal

This involves sanding the floor down to bare wood and applying a clear protective finish. It works well when the existing stain color is acceptable but the finish is worn, scratched, or dull. Most homeowners choose this option when their floors look tired but the wood itself is in decent shape.

Full Refinish with Stain

A full refinish includes sanding, applying a new stain color, and finishing with multiple coats of polyurethane or another protective coating. This is the right choice when you want to change the floor color or the existing stain is uneven and patchy.

Screen and Recoat

If your floors are only lightly worn with minor surface scratches, a screen and recoat can restore the shine without a full sanding. This process lightly abrades the existing finish and applies a new topcoat. It is the most affordable option and can extend the life of your finish by several years.

Factors That Affect Refinishing Cost

Floor Condition

Floors with deep scratches, pet stains, water damage, or significant wear require more sanding passes and may need wood filler or board replacements. Heavily damaged floors can push costs toward the higher end of the range. Pet urine stains that have penetrated the wood may not come out completely even with sanding.

Finish Type

Oil-based polyurethane is the traditional choice and costs less, but it takes longer to dry and has a yellowish tint. Water-based polyurethane dries faster, stays clear, and has lower odor, but costs 10 to 20 percent more. Hardwax oil finishes are gaining popularity for their natural look and easy spot-repairability, priced at $6 to $9 per square foot installed.

Room Size and Accessibility

Larger rooms cost less per square foot because the setup and cleanup time is spread over more area. Small rooms, closets, hallways, and stairs are more labor-intensive per square foot due to tight spaces and the need for hand-sanding in corners and along edges.

Furniture Moving

Most refinishing quotes assume empty rooms. If the contractor needs to move furniture, expect an additional charge of $100 to $300 or more depending on the amount. Many homeowners move furniture themselves to save on this cost.

Refinishing vs. Replacing Hardwood Floors

Refinishing is almost always cheaper than replacing, but there are situations where replacement makes more sense.

Choose refinishing when:

• The wood is structurally sound with no soft spots or warping
• Floors have been refinished fewer than 3 to 4 times previously
• The boards are at least 3/4 inch thick with enough wood above the tongue to sand
• You want to update the look without a major renovation

Choose replacement when:

• Boards are warped, cupped, or buckling from moisture damage
• The wood has been sanded too many times and is too thin
• You want to change to a different wood species or plank width
• Subfloor damage requires pulling up the existing floor

Replacing hardwood floors costs $8 to $15 per square foot installed, compared to $3 to $8 for refinishing. For more on flooring installation pricing, see our flooring installation cost guide.

How Long Does Refinishing Take?

A typical room takes 2 to 5 days to complete, including sanding, staining, and applying two to three coats of finish with drying time between coats. Water-based finishes dry faster and can reduce the timeline. You should plan to stay off the floors for at least 24 to 48 hours after the final coat and avoid placing furniture or rugs for a full week.
