How much does it cost to refinish a hardwood gym floor?

The cost to refinish a hardwood gym floor depends on its size, condition, location, and the exact scope, so a reliable price requires an on-site assessment. Refinishing normally involves more than applying a new finish.

Cost drivers can include repairs, sanding, removal or recreation of game lines and graphics, the selected coating system, number of coats, labor rates, access, dust control, ventilation, curing time, and protection of adjacent areas. Deep damage, uneven boards, moisture problems, or previous incompatible coatings may require extra work before finishing can begin. The downtime required for preparation, coating, and cure can also affect the facility's overall project cost.

Ask contractors to quote the same measured area and specification. Each proposal should state repairs, sanding stages, line marking, graphics, finish products, coats, curing conditions, cleanup, and exclusions. A lower price is not directly comparable if it omits preparation or court markings. If the floor only has light finish wear, confirm whether recoating could be appropriate instead of full sanding and refinishing.
