Hardwood floors add warmth and character to any home, but they don’t stay flawless forever. Over time, scratches, dullness, and everyday wear can take a toll. That’s when many homeowners consider refinishing.
Before you commit, it’s important to understand the hardwood floor refinishing cost and what factors can drive that number up or down. This guide breaks it all down, so you can plan with confidence and avoid surprise expenses.
Average Cost to Refinish Hardwood Floors
The national average hardwood floor refinishing cost in 2025 is between $4 and $8 per square foot. That means:
- A 200-square-foot room may cost around $800 to $1,600
- A 1,000-square-foot space could cost $4,000 to $8,000
If your floors are in good shape, the low end is likely. But if there’s damage, stains, or deep wear, expect to pay more.
These numbers align with industry estimates reported by HomeAdvisor, a trusted source for home improvement costs.
What’s Included in That Price?
Refinishing usually includes these steps:
- Sanding – The top layer is sanded down to remove old finish, scratches, and stains.
- Repairs – Some boards may be patched, filled, or replaced if needed.
- Staining (optional) – If you want to change the color of your floors, stain is applied.
- Sealing – A protective finish is applied. This can be oil-based, water-based, or other specialty coatings.
Basic refinishing jobs with no stain are cheaper. Staining and multiple coats of finish can increase labor and materials.
Factors That Change the Cost: Floor Size and Layout
The bigger the space, the more materials and labor you’ll need. But it’s not just about square footage—layout matters too. Tight corners, stairs, or odd-shaped rooms can take more time and drive up the cost.
Floor Condition
If your floors are deeply scratched, warped, or stained, the work will take longer. You may need repairs or extra sanding passes. Water damage or pet stains can add even more to the bill.
Type of Wood
Some woods are harder to sand than others. Exotic hardwoods like Brazilian cherry or mahogany may cost more because they need special care or tools. Softer woods like pine may need gentler handling.
Type of Finish
You’ll choose between different types of finishes:
- Oil-based polyurethane: Durable, warm look, longer drying time, stronger odor
- Water-based polyurethane: Dries faster, less smell, slightly higher cost
- Hardwax oils or specialty finishes: More natural look, but often pricier
Each type has its own cost and lifespan. Most professionals will guide you to the best option for your home.
DIY vs Hiring a Pro
You can rent sanding equipment and try to do it yourself. The cost for a DIY project is usually around $500 to $1,000, depending on the room size and tools needed.
But refinishing floors is not easy. It’s loud, dusty, and takes precision. One mistake can damage the wood or leave uneven spots.
Hiring a pro costs more, but it often looks better and lasts longer.
Extra Costs You Might Not Expect: Moving Furniture
Most contractors won’t move furniture for free. You’ll need to clear the space before they arrive. If you need help, expect to pay extra.
Floor Prep
Old nails, staples, carpet glue, or paint spills need to be removed before sanding. This can take extra time and add cost.
Baseboard or Trim Work
Sometimes the baseboards need to be removed or touched up. If they get scratched or don’t match the new floor finish, you may need paint or replacements.
Clean-Up
Dust from sanding can get everywhere. Some companies include a basic clean-up, but others charge extra for deep cleaning or dust containment systems.

How Long Does It Take?
Most refinishing jobs take 3 to 5 days from start to finish, depending on the room size, drying time, and type of finish.
You’ll also need to stay off the floors while they dry. Furniture can’t go back until the final coat has fully cured, which may take another 2 to 7 days.
When Is It Time to Refinish?
You don’t have to wait until your floors look terrible. Here are signs it’s time to refinish:
- Dull or cloudy finish that doesn’t shine
- Deep scratches or grooves
- Discoloration or stains that don’t clean up
- Wood feels rough or worn
- Finish has worn off in high-traffic areas
If the wood is still thick enough for sanding, refinishing is a great way to refresh your floors without replacing them.
Refinishing your hardwood floors costs money—but it’s usually worth it. Compared to replacing flooring, it’s a more affordable way to upgrade your space.
Know your square footage, check the condition of your floors, and get a few quotes. Ask what’s included, and don’t forget to budget for extras like moving furniture or clean-up.
Done right, refinished floors can last 7 to 10 years or more. And they’ll look brand new every time you walk into the room.
