The style, color and materials used to refinish the floor all impact the cost of wood floor refinishing. Refinishing a wood floor generally requires refinishing the entire floor to avoid color and shine variations and refinishing an entire floor usually costs around $4 per square foot, as of 2015.
Refinishing a wood floor, even a large one, is far less expensive than replacing the floor and, if done properly, the result will be a floor that looks brand new for a fraction of the cost.
The most common factor in refinishing a wood floor is the price of the materials used. If the floor needs a water-based finish, the price will be lower. Polyurethane and acid finishes will be more expensive. Homeowners with a little know-how can refinish their floors themselves, saving hundreds of dollars, but the risk of damage may not be worth the savings.
To refinish a wood floor, professional refinishers will either buff the surface or sand and finish the floor. The cost of the service will depend on the amount of damage to the floor, and the price of sanding and finishing begins at around $1.50 per square foot.
Homeowners who choose to tackle the task of refinishing a floor will need to rent or purchase a buffer and buy at least one gallon of floor finish. The cost of these items vary and will affect the cost of refinishing a floor.
