One of the most common questions we hear from homeowners is: "How often do I need to refinish my hardwood floors?" The answer isn't as simple as a specific number of years—it depends on several factors including traffic, maintenance, and the type of finish. As a third-generation hardwood floor professional, I'll share what three generations of experience has taught us about when refinishing is truly necessary.
TL;DR: When to refinish hardwood floors
Most hardwood floors need refinishing every 7-10 years, but visible wear matters more than the calendar.
- Refinish sooner if the finish is worn through to bare wood.
- Deep scratches, stains, gray patches, or rough boards need professional evaluation.
- Recoating can add 3-5 years when the finish is worn but the wood is still protected.
- High-traffic homes, pets, kids, and moisture can shorten the timeline.
- Ask for an assessment before sanding engineered hardwood.
The General Rule: 7-10 Years
As a general guideline, most hardwood floors need refinishing every 7-10 years. However, this is just a starting point. Some floors may need attention sooner, while well-maintained floors in low-traffic areas can go 15-20 years or more.
Important Distinction
Refinishing involves sanding down the wood and applying new finish. This is different from recoating, which is applying a new topcoat without sanding. Recoating can extend the time between full refinishing by 3-5 years if done at the right time.
Signs It's Time to Refinish
Rather than waiting for a specific number of years, watch for these telltale signs that your floors need professional attention:
1. The Finish is Worn Through
In high-traffic areas like hallways, entryways, and in front of kitchen sinks, you may notice the finish has completely worn away, exposing bare wood. This is the most obvious sign that refinishing is needed. The wood will look dull and may feel rough to the touch.
2. Deep Scratches and Gouges
Surface scratches that only affect the finish can sometimes be spot-repaired. But when scratches go deep into the wood itself, or when there are many scratches throughout the floor, refinishing is the best solution. This is especially common in homes with pets or heavy furniture that's been moved around.
3. Discoloration and Stains
Water damage, pet accidents, or other stains that have penetrated the finish and discolored the wood require refinishing. Sometimes these can be sanded out; other times, the affected boards may need to be replaced before refinishing.
4. The Floor Looks Dull Despite Cleaning
If your floors look dull and lifeless even after a thorough cleaning, the finish has likely worn thin. A fresh refinishing will restore the original luster and protect the wood underneath.
5. Gaps and Movement
While some seasonal movement is normal, excessive gaps, cupping, or crowning can indicate moisture issues that need to be addressed before or during refinishing.
Factors That Affect Refinishing Frequency
Traffic Level
High-traffic areas (entryways, hallways, kitchens, living rooms) will need refinishing more frequently—possibly every 5-7 years. Low-traffic areas (bedrooms, formal dining rooms) may go 15-20 years between refinishing.
Type of Finish
- Polyurethane (water-based): Typically lasts 7-10 years with proper care. Dries clear and is low-odor.
- Polyurethane (oil-based): Can last 10-15 years. Slightly more durable but takes longer to dry and has more odor during application.
- Hardwax oil: May need more frequent maintenance (every 3-5 years) but is easier to spot-repair.
- Lacquer: Older finish type that typically needs refinishing every 5-7 years.
Maintenance Quality
Floors that are properly maintained—regular cleaning, immediate spill cleanup, furniture pads, area rugs in high-traffic zones—will last significantly longer between refinishing than floors that are neglected.
Wood Species
Softer woods like pine may show wear more quickly and need refinishing more often. Harder species like oak, maple, and hickory are more durable and can go longer between refinishing.
Pets and Children
Homes with active pets or young children typically need refinishing more frequently due to increased wear, scratches, and potential accidents. Plan for refinishing every 5-7 years in these situations.
Can You Extend Time Between Refinishing?
Yes! With proper maintenance and timely recoating, you can significantly extend the time between full refinishing projects.
Recoating: The Smart Alternative
If your floors are still in good condition but the finish is starting to look worn, recoating (applying a new topcoat without sanding) can refresh the appearance and add 3-5 more years of protection. This is much less expensive and disruptive than full refinishing.
Recoating works best when:
- The wood itself is still in good condition
- There are no deep scratches or gouges
- The finish is thin but not completely gone
- There's no significant discoloration or water damage
What to Expect During Refinishing
Understanding the sanding and refinishing process helps you prepare and know what to expect:
The Process
- Preparation: Furniture is moved, baseboards are protected, and the area is prepared for dust containment.
- Sanding: The old finish is sanded off using progressively finer grits of sandpaper, typically starting at 36-40 grit and finishing at 120 grit.
- Repairs: Any damaged boards are replaced, gaps are filled if needed, and the floor is thoroughly cleaned.
- Staining (optional): If you want to change or refresh the color, stain is applied at this stage.
- Finishing: Multiple coats of finish are applied, with sanding between coats for a smooth, professional result.
- Curing: The finish needs time to fully cure before furniture can be moved back (typically 24-48 hours for water-based, 48-72 hours for oil-based).
Timeline
Most refinishing projects take 3-5 days, depending on the size of the area and the number of finish coats. You'll need to plan to be out of the space during the sanding phase (typically day 1-2) due to dust, even with modern dust-containment systems.
How Many Times Can You Refinish?
This depends on the thickness of your hardwood flooring:
- Solid hardwood: Can typically be refinished 5-7 times, sometimes more depending on the original thickness. Most solid hardwood is 3/4" thick, giving plenty of material to work with.
- Engineered hardwood: Can usually be refinished 2-3 times, depending on the thickness of the top veneer layer. Always check with a professional before refinishing engineered floors.
Pro Tip
Each sanding removes about 1/32" to 1/16" of wood. With proper maintenance between refinishing, your solid hardwood floors can last 100+ years with multiple refinishing cycles.
Cost Considerations
Refinishing costs vary based on:
- Square footage of the area
- Condition of the floors (more repairs = higher cost)
- Type of finish chosen
- Whether staining is included
- Accessibility and complexity of the space
In the Greater Seattle area, expect to pay $3-7 per square foot for professional refinishing, depending on the factors above. While this is an investment, refinishing is significantly less expensive than replacing floors and can restore them to like-new condition.
When to Call a Professional
While DIY refinishing is possible, it's one of the most challenging home improvement projects. Here's why professional refinishing is worth it:
- Proper equipment: Professional sanders and dust-containment systems produce better results with less mess.
- Experience: Knowing the right sanding sequence, when to stop sanding, and how to apply finish evenly comes from years of practice.
- Time savings: What takes a professional 3-5 days might take a DIYer 2-3 weeks.
- Warranty: Professional work comes with guarantees on both materials and labor.
- Risk reduction: Mistakes in refinishing can be costly to fix. Professionals have the experience to avoid common pitfalls.

Hardwood Refinishing FAQ
Can I recoat instead of refinish?
Sometimes. Recoating can work when the finish is worn but still intact. If scratches, stains, or bare wood are visible, full sanding and refinishing is usually the better fix.
How do I know if my floor is solid or engineered?
A floor professional can usually tell by checking a vent, transition, or exposed edge. Engineered floors may still be refinishable, but the top veneer thickness matters.
How can I make refinishing last longer?
Keep grit off the floor, clean spills quickly, use felt pads and rugs, and maintain indoor humidity. Our hardwood floor maintenance guide covers the day-to-day habits that protect the finish.
