The Basics of Hardwood Floor Refinishing
Hardwood floor refinishing involves several key steps that transform tired floors into stunning focal points. We begin with a detailed inspection to check for damage, wear patterns, and structural issues. This helps us determine the best approach for your specific floors.
The process starts with sanding, which removes the old finish, stains, and surface damage. We use professional-grade equipment that minimizes dust and creates a smooth surface. After sanding, we clean the floor thoroughly to prepare it for staining.
If you want to change or enhance the color, we apply stain at this stage. Our experts help you choose the right shade that complements your home's style. Finally, we apply several coats of protective finish that shield your floor from daily wear while highlighting the wood's natural beauty.
When to Determine Refinishing Is Necessary
Several signs indicate it's time to refinish your hardwood floors. The most obvious is visible wear – scratches, dents, and dull patches that detract from your floor's appearance. If water no longer beads on the surface but instead soaks in, your protective finish has worn away.
Faded areas, especially in high-traffic zones or sun-exposed sections, suggest it's time for refinishing. Gray or black spots can signal water damage that needs addressing before it worsens.
We recommend checking hidden spots under furniture or rugs and comparing them to exposed areas. A significant difference in color or shine indicates wear that refinishing can correct.
Most hardwood floors need refinishing every 7-10 years, but this varies based on foot traffic, maintenance practices, and quality of previous finishes. Our experts can assess your specific situation and recommend the best timing for optimal results.
Our Hardwood Floor Refinishing Process
Our comprehensive approach ensures your floors will look beautiful and last for years to come.

1. Initial Assessment and Consultation
We begin with a thorough inspection of your hardwood floors. Our experts check for damage, uneven areas, and structural issues that need attention. We'll measure the room and document wear patterns to develop a tailored refinishing plan.
During this visit, we discuss your vision for the floors. Do you want to maintain the current color or try something new? Are there specific areas that need special attention? We'll answer all your questions about the process, timeline, and what to expect.
We provide a detailed written estimate that includes all costs with no hidden fees. Our transparent approach helps you make an informed decision about your floor refinishing project.
2. Preparation and Repair Work
Before refinishing begins, we prepare your space properly. We help you move furniture and protect your belongings by covering them or suggesting temporary removal. We seal off other rooms to prevent dust from spreading throughout your home. Next, we address any repairs needed:
- Replacing damaged boards
- Fixing loose planks
- Filling gaps between boards
- Addressing squeaky spots
- Leveling uneven areas
For older floors with significant damage, we might recommend board replacement in certain sections. Our repair work ensures your floors have a solid foundation before the refinishing process begins.
3. Sanding and Staining
We use professional-grade dustless sanding equipment to remove the old finish and expose fresh wood. Our multi-step sanding process includes:
- Rough sanding to remove old finish and level the surface
- Medium sanding to smooth the wood
- Fine sanding for a perfectly smooth finish
After sanding, we carefully clean the entire area to remove all dust. Then comes the staining process if you've chosen to change or enhance your floor's color. We offer numerous stain options, from light natural tones to rich dark finishes.
We apply stain evenly and allow proper drying time between coats. This careful approach ensures consistent color throughout your floors.
4. Sealing and Finishing Touches
The final step is applying a protective finish coat to your freshly sanded and stained floors. We offer several finish options:
Water-based polyurethane:
- Fast-drying (24-48 hours)
- Low odor
- Environmentally friendly
- Clear finish that won't yellow
Oil-based polyurethane:
- Traditional finish
- Deeper, richer appearance
- More durable in high-traffic areas
- Longer curing time (3-7 days)
We typically apply 3-4 coats of finish, allowing proper drying time between each application. After the final coat, we recommend limited traffic for several days while the finish fully cures.
We perform a final inspection to ensure every square inch meets our high standards before considering the job complete.
5. Long-Term Care
Clean your floors every 1-2 weeks with a hardwood floor cleaner recommended by our technicians. Avoid using vinegar, soap-based cleaners, or wax products that can dull the finish. Maintain consistent indoor humidity levels (between 35-55%) to prevent wood from expanding or contracting. Use a humidifier in winter and air conditioning in summer if needed.
We recommend professional deep cleaning once a year to remove embedded dirt and refresh the protective coating. This extends the life of your refinishing job significantly. Watch for signs of wear in the finish, especially in high-traffic areas. Small issues can often be addressed with a screen and recoat rather than a full refinishing.
When to Call Us: If you notice dullness that doesn't improve with cleaning, scratches that catch your fingernail, or discoloration, it may be time for professional attention.
Materials and Techniques Used
We follow a detailed process that preserves the natural beauty of your floors while providing protection that stands up to daily wear.
Types of Finishes Available
We offer several finish options to match your lifestyle needs and aesthetic preferences:
- Oil-based polyurethane - Provides a warm, amber glow and excellent durability. Takes longer to dry but creates a rich, traditional look.
- Water-based polyurethane - Dries quickly and maintains the wood's natural color. Produces less odor and VOCs than oil-based options.
- Hard-wax oils - Penetrates deeply into wood for a natural, low-sheen finish. Easy to spot-repair and environmentally friendly.
- Swedish finishes - Extremely durable acid-cured finishes for high-traffic areas.
Each finish type has unique properties regarding sheen levels (matte, satin, semi-gloss, gloss), durability, and maintenance requirements. We'll help you choose the right option for your specific needs.

Innovative Refinishing Technologies
Our team uses the latest refinishing technologies to deliver superior results:
- Dustless sanding systems - Capture up to 98% of airborne dust during the sanding process, keeping your home cleaner.
- Commercial-grade drum and edger sanders - Ensure even, consistent sanding across your entire floor surface.
- UV-cured finishes - Instant-curing technology using ultraviolet light allows for faster project completion and immediate floor use.
We also employ advanced staining techniques like water-popping, which opens wood grain for deeper, more uniform color absorption. For older floors, we use specialized repair methods including board replacement and custom color matching to maintain your floor's original character.

FAQs About Hardwood Floor Refinishing
We've compiled answers to the most common questions about our hardwood floor refinishing services. These insights will help you understand our process, options, and what makes our work exceptional.
What is the standard process for refinishing hardwood floors with San Francisco Flooring Company?
Our refinishing process begins with a thorough assessment of your floors. We then clear the space and protect your home from dust and debris. Next, we sand the floors to remove the old finish and imperfections. We start with coarse-grit sandpaper and gradually move to finer grits for a smooth surface. After sanding, we clean the entire area and apply stain if desired. We finish with 2-3 coats of polyurethane or other sealants, allowing proper drying time between applications.
Are there different refinishing options available for varying wood floor conditions?
Yes, we offer several refinishing options based on your floor's condition. For floors with minor wear, we provide a screen and recoat service that refreshes the surface without deep sanding. For more damaged floors, our full refinishing service removes all imperfections and creates a new surface. We also offer specialized services for antique or historic floors that require gentle restoration techniques to preserve their character.
How do San Francisco Flooring Company's services stand out in terms of quality and reliability?
We use commercial-grade equipment and premium finishes that exceed industry standards. Our sanders produce more consistent results than rental equipment, eliminating swirl marks and uneven surfaces. Our technicians have an average of 12 years of experience in hardwood refinishing. This expertise allows us to handle unexpected challenges that often arise with older floors. We also provide detailed contracts and warranties on our work, giving you peace of mind about your investment.
Can you provide an estimated timeline for a typical hardwood floor refinishing project?
Most residential refinishing projects take 3-5 days from start to finish. Day 1 includes preparation and sanding. Days 2-3 involve staining and applying the first coats of finish. The final coats and cure time typically take another 1-2 days. Larger projects or those requiring specialized techniques may take longer. We always provide a specific timeline during our initial consultation based on your unique project requirements.
How often is it recommended to refinish hardwood floors to maintain their quality?
Hardwood floors typically need refinishing every 7-10 years with normal use. However, high-traffic areas may require attention sooner. We recommend a maintenance coat every 3-5 years to extend the life of your finish. This involves light buffing and applying a new topcoat without full sanding. Regular cleaning with products designed for hardwood floors will also extend the life of your finish and reduce the frequency of refinishing.
