How Often Should You Refinish Hardwood Floors? A Professional’s Guide to Timing and Care

Hardwood flooring adds long-term value and beauty to a home, but it requires periodic maintenance to stay in top condition. One of the most important maintenance steps is refinishing. Knowing when to refinish hardwood floors ensures longevity, improves appearance, and protects your investment. In this guide, we’ll walk through how often refinishing should be done, signs that it’s time, what impacts the timing, and how to care for floors between refinishing projects.

What Does Hardwood Floor Refinishing Involve?

Hardwood floor refinishing is the process of sanding down the top layer of wood to remove surface damage, scratches, and worn finishes. After sanding, a new stain or clear coat is applied. This restores the floor’s appearance and adds a layer of protection.

Refinishing differs from screening and recoating, which involves lightly sanding and applying a new topcoat without removing the existing finish completely.

How Often Should Hardwood Floors Be Refinished?

Most hardwood floors should be refinished every 7 to 10 years, but several factors can shift that timeline.

General Guidelines:

• Light Traffic Homes: Every 10–12 years
  
  
• Moderate Traffic Homes: Every 7–10 years
  
  
• High Traffic or Pet-Friendly Homes: Every 3–5 years
  
  

These are averages and not hard rules. Visual cues and wear patterns are better indicators of when it's time.

Signs It’s Time to Refinish Hardwood Floors

Depending on wear levels, you may only need a screening instead of full sanding to refresh your floor’s look. Instead of counting years, monitor the condition of your floors. Here are the most common signs it’s time for refinishing:

1. Worn or Dull Finish

• If your floor looks dull or lacks the luster it once had, refinishing can restore its shine.
  
  

2. Scratches and Surface Damage

• Heavy surface scratches, especially those that cut into the wood, signal the need for sanding and refinishing.
  
  

3. Water Damage or Stains
   

• Gray or black stains often indicate moisture penetration. If these marks don’t buff out, refinishing is necessary.
  
  

4. Wood Discoloration
   

• Sun fading and age-related discoloration can make floors appear uneven. Refinishing brings consistency.
  
  

5. Bare Spots

• If the protective coating is completely worn through in high-traffic areas, it’s time to act before the wood becomes damaged.

Factors That Affect Refinishing Frequency

Several variables influence how often your floors need refinishing:

1. Wood Species

• Harder woods like oak or maple resist wear longer than softer woods like pine. Softer woods may show signs of damage sooner.
  
  

2. Type of Finish

• Oil-based polyurethane tends to last longer (8–10 years) than water-based finishes (3–7 years).
  
  
• Penetrating oil finishes require more frequent maintenance but can be spot-repaired.
  
  

3. Foot Traffic

• Homes with children, pets, or large families naturally put more wear on floors, shortening the refinishing cycle.
  
  

4. Cleaning and Maintenance

• Regular sweeping, gentle mopping, and area rugs help extend the finish life. Harsh cleaners and moisture shorten it.
  
  

5. Sunlight Exposure

• UV rays can fade the stain and dry out the wood. Window treatments or UV-protective finishes can help.
  
  

Can All Hardwood Floors Be Refinished?

Most solid hardwood floors can be refinished multiple times, usually between 4 to 6 times, depending on the thickness of the wood. Engineered hardwood can sometimes be refinished once or twice if the top veneer layer is thick enough (usually at least 2–3mm).

Before proceeding with refinishing, a flooring professional should inspect the floors to determine if there’s enough wood left to sand safely. To understand better, learn more from a full hardwood floor repair guide.

Refinishing vs. Replacing: Know the Difference

When refinishing is no longer an option—due to repeated sanding or extensive water damage—replacement may be necessary. Here are a few ways to tell the difference:

• If floors have deep structural damage, warping, or are thinner than 1/8", replacement is likely better.
  
  
• If damage is cosmetic or surface-level, refinishing is more cost-effective.
  
  

Maintaining Hardwood Floors Between Refinishing

To extend the time between refinishing jobs:

1. Sweep or Vacuum Regularly

• Use a soft-bristle broom or vacuum with a hardwood floor attachment.
  
  

2. Use Rugs and Runners
   

• Especially in high-traffic zones like entryways and hallways.
  
  

3. Wipe Spills Immediately
   

• Water and moisture are major threats to hardwood flooring.
  
  

4. Avoid Harsh Chemicals
   

• Use pH-neutral wood floor cleaners.
  
  

5. Consider a Recoat Every Few Years
   

• Screening and recoating can refresh the surface and delay full refinishing.
  
  

Professional vs. DIY: What’s Best?

While DIY refinishing is possible, it’s a labor-intensive process that requires skill and proper equipment. Poor sanding technique can damage floors permanently. Hiring a professional ensures even sanding, proper stain application, and a long-lasting finish. If it’s time to refinish, selecting the right type of finish is key to achieving the look and performance you want.

FAQs: Refinishing Hardwood Floors

1. How long does hardwood floor refinishing take?
   

   Refinishing typically takes 3–5 days, depending on square footage and drying times for the finish.

2. Is there a limit to how many times you can refinish a floor?
   

   Yes. Solid hardwood can usually be refinished 4–6 times, while engineered hardwood may only be refinished once or twice, depending on the veneer thickness.

3. Can I change the color of my floors during refinishing?
   

   Yes. Sanding removes the existing stain, allowing you to choose a new color or finish type.

4. Will refinishing remove deep gouges or pet stains?
   

   Refinishing can remove surface-level scratches and stains, but deep damage may remain or require wood filler or board replacement.

5. What’s the cost to refinish hardwood floors?
   

   The average cost ranges from $3 to $8 per square foot, depending on your location, floor condition, and finish type.
