Wood floors are a durable and renewable flooring option that can be refinished multiple times throughout their lifespan. When maintained properly, wood floors are capable of lasting hundreds of years, making them one of the most sustainable flooring options available. Generally speaking, most solid wood floors can be sanded six to eight times during their overall service-life. A traditional sand job will remove 1/32” to 1/16” of actual material from the surface of the floor.
