Hardwood floor refinishing costs $3 to $8 per square foot and extends the life of your floors by 10 to 15 years. If your hardwood has deep scratches, dull finish, or water damage, refinishing is typically worth it for quality wood floors that are in structurally sound condition.
Refinishing is a major project that requires sanding the old finish off, staining if desired, and applying new protective coats. The results can transform an old, worn floor into a showpiece.
Hardwood Refinishing Costs
Professional hardwood refinishing costs $3 to $5 per square foot for sanding and recoating with a natural finish. Staining adds $1 to $2 per square foot. Repairing damaged boards costs extra. For a 500-square-foot area, expect to pay $1,500 to $4,000. DIY refinishing costs about $1 to $2 per square foot for rental equipment and supplies but requires significant skill and time.
The Refinishing Process
The process starts with sanding using progressively finer grits to remove the old finish and smooth the wood. Any damaged boards are replaced at this stage. Stain is applied if desired, then two to three coats of polyurethane or other finish are applied, with light sanding between coats. Each coat takes 24 hours to dry, so the process takes several days. Furniture must be moved out of the room for the duration.
Is Refinishing Worth It?
Refinishing is absolutely worth it for solid hardwood floors in good structural condition. It costs a fraction of replacement and can make floors look brand new. For engineered hardwood, refinishing is possible but only once or twice depending on the thickness of the wear layer. For laminate or very thin engineered wood, replacement is the better option. Refinishing can increase your home's resale value.
Alternatives to Refinishing
If your hardwood has minor wear but is in decent shape, a screening and recoat can refresh the finish without full sanding. This costs $1 to $2 per square foot. For floors that are too thin to sand, consider luxury vinyl plank as a durable overlay. For budget-conscious homeowners, area rugs can temporarily hide worn sections until refinishing is in the budget.
