Understanding Gym Floor Refinishing Costs for Trade Professionals

Refinishing a gym floor in a residential setting involves several factors that influence the overall cost. For construction trade professionals, understanding these elements is crucial for accurate budgeting and project planning. On average, refinishing a 400 sq ft hardwood gym floor costs between $3.25 and $6.00 per square foot, totaling approximately $1,300 – $2,400. This guide provides a detailed breakdown of costs and strategies to manage expenses effectively.

Average Residential Gym Floor Refinishing Cost

In most single-family homes, the cost of refinishing a gym floor varies based on the scope of work:

  • Light buff and re-coat: $1.00 – $2.00 per sq ft
  • Full sand, stain, and poly finish: $3.25 – $6.00 per sq ft
  • Board replacement and custom court lines: $7.00 – $10.00 per sq ft

Key Cost Drivers for Gym Floor Refinishing

1. Floor Condition

Minor surface scratches may only require a screen and re-coat, reducing labor costs. However, deep gouges necessitate full sanding to bare wood.

2. Wood Species

Maple and white oak are popular choices for their durability. Harder woods require additional sanding, increasing labor by 10 – 15%.

3. Finish Choice

  • Water-based poly: fast cure, low odor, $45-$60 per gallon
  • Oil-based poly: warm tone, longer life, $30-$45 per gallon
  • High-performance conversion varnish: commercial-grade durability, $80-$110 per gallon

4. Logo or Court Striping

Adding custom designs like basketball key lines can add $250 to $1,000 depending on complexity.

5. Furniture and Equipment Moving

Handling fees apply if equipment remains in the room, typically 1 labor hour per 100 lb item.
