The cost of Hardwood Floor Refinishing depends on a number of factors, including the size of the floor, the type of wood, and the condition of the existing finish. For a small room, expect to pay around $300 for hardwood floor refinishing. For a larger space, the cost can increase to $1,000 or more. The type of wood will also affect the price. Harder woods, such as oak and maple, are more difficult to refinish and will generally cost more than softer woods, such as pine. Finally, the condition of the existing finish will impact the price. If the finish is in good condition, it will be easier to refinish and will likely cost less than if the finish is damaged or needs repair.
