In many cases, professional **hardwood floor refinishing** can remove decades of wear and restore the existing wood to a remarkably close-to-new appearance. National Floors specializes in hardwood floor sanding, staining and refinishing throughout the San Francisco Bay Area. As a California C-15 licensed flooring and floor covering contractor, we complete more than 100 refinishing projects each year and have extensive experience with solid and engineered hardwood floors, repairs, staining, color changes and professional water-based finish systems. ### Why Homeowners Choose National Floors ✓ Very Competitive Pricing | ✓ A 5-Star Reputation | ✓ C-15 Licensed, Bonded & Insured ✓ A No Deposit Policy | ✓ A Real Person Answers the Phone | [**✓ 2 Year Warranty**](https://www.national-floors.com/services/index.php?Itemid=1081) | ✓ Financing Available ## Why Refinish Hardwood Floors Instead of Replacing Them? One of the great advantages of genuine hardwood flooring is that a floor can look badly worn long before it actually needs to be replaced. Professional sanding removes the old finish and a small amount of the damaged wood surface, exposing fresh wood underneath. Scratches, worn traffic areas, discoloration and an outdated stain color can often disappear during refinishing. The floor can remain natural or be stained an entirely different color, allowing homeowners to dramatically change its appearance without replacing the existing hardwood. When the hardwood is structurally sound, refinishing is generally considerably less expensive than replacement and can extend the useful life of the floor for many years. ## [!\[Get an Instant Hardwood Flooring Quote from National Floors\](https://www.national-floors.com/services/images/CityPhotos/Instant_Flooring_Quote_Button_National_Floors-904x204.png)](https://www.national-floors.com/services/index.php?Itemid=108) ## Our Hardwood Floor Refinishing Process Professional hardwood floor refinishing can be broken into three primary stages. ### 1. Assessment Before turning on a sanding machine, we inspect the hardwood species, construction, existing finish, wear, stains and damage. We also determine whether the floor is solid or engineered hardwood and whether previous sanding affects what can safely be done. ### 2. Sanding Professional sanding equipment removes the old finish and damaged wood surface while flattening the floor. The hardwood is sanded through progressively finer stages, and wood filler is used where appropriate for hairline cracks, nail holes and minor imperfections. Once sanding is complete, the worn surface you started with is gone. ### 3. Stain and Finish After sanding, the hardwood can remain natural or be stained to change its color. We then apply a professional water-based finish system to protect the newly sanded wood. Our professional-grade finishes provide excellent durability and practical drying times. Floors can typically be walked on within 24 hours, and furniture can generally be carefully replaced within 48 hours. ## Can Your Hardwood Floors Be Refinished? Most traditional solid hardwood floors can be sanded and refinished multiple times because there is substantial usable wood above the tongue and groove. Previous sanding history and the current condition of the floor still need to be considered. Engineered hardwood requires more caution. Only the upper wear layer is genuine hardwood, and its thickness determines whether the floor can safely be sanded. Some engineered floors can be professionally refinished; others cannot. We determine what type of floor you have and how much usable wood is available before recommending sanding. ## Hardwood Floor Staining and Color Changes Refinishing doesn't mean your hardwood floors have to look the same afterward. Once the old finish and stain are removed, the floor can remain natural or be stained an entirely different color. Oak accepts a broad range of stain colors, while species such as maple require additional care to produce a consistent appearance. We help homeowners determine what colors are realistic for their particular hardwood before staining begins. ## Sand and Refinish vs. Screen and Recoat Not every worn hardwood floor needs to be completely sanded. If the wood itself is in good condition and only the protective finish has become worn, a professional screen and recoat may extend the life of the existing finish without unnecessarily removing wood. A recoat cannot remove deep scratches, gouges, discoloration, damaged stain or other problems extending into the wood. Those conditions require sanding because the damaged wood surface itself must be removed. **A recoat renews the protective surface. Refinishing renews the wood surface.** ## What Does Hardwood Floor Refinishing Cost? Hardwood floor refinishing cost depends on the size and condition of the floor, repairs that may be necessary, whether the floor will remain natural or be stained, the finish system selected, stairs and other project requirements. Even a small refinishing project requires equipment setup and multiple stages of sanding and finishing, which is why larger projects generally have a lower cost per square foot. The most accurate way to determine cost is to see the floor. National Floors provides **free in-home estimates** throughout our Bay Area service area. A typical inspection takes approximately 10–15 minutes and allows us to determine what your floor actually needs rather than guessing based solely on square footage. ## Real Hardwood Floor Refinishing Results Every hardwood floor presents a different challenge.
