The honest answer is sometimes—but not if the floor truly needs refinishing.
Many homeowners use the words refinish and recoat interchangeably, but they're actually two very different services. Understanding the difference can help you avoid unnecessary expense and choose the right solution for your floor.
What Is True Refinishing?
Refinishing means sanding the hardwood back to bare wood before applying a new finish. This process removes scratches, worn finishes, minor imperfections and, if desired, allows the stain color to be changed.
Because the old finish is completely removed, the floor receives an entirely new surface.
What Can Be Done Without Sanding?
If the existing finish is still in good condition, a maintenance coat may be an option.
Instead of sanding the hardwood down to bare wood, the existing finish is lightly prepared and another coat of finish is applied over it. This renews the protective surface, but it does not remove deep scratches, stains, damaged boards or worn areas where bare wood is already exposed.

When Sanding Is Necessary
If your hardwood floor has deep scratches, black water stains, pet damage, heavy traffic patterns or worn areas where the finish has completely disappeared, sanding is almost always required.
Trying to avoid sanding in these situations usually produces disappointing results because the underlying damage remains trapped beneath the new finish.
Don't Be Misled by Advertising
Some advertisements suggest hardwood floors can always be restored without sanding. While those claims sound appealing, they often apply only to floors whose existing finish is still in excellent condition.
Once the wood itself has become damaged, a maintenance coat cannot restore what has already been lost.
The Best Choice Depends on Your Floor
No two hardwood floors are exactly alike. Some homeowners are excellent candidates for a simple maintenance coat, while others will benefit far more from complete refinishing.

An Inspection Eliminates the Guesswork
The only reliable way to determine whether sanding is necessary is to inspect the floor.
A professional evaluation can identify the condition of the existing finish, determine whether the wood has been exposed and recommend the most practical solution based on your specific floor—not a generic advertisement or online claim.
Choosing the correct process from the beginning helps ensure your hardwood floors receive exactly the treatment they need while avoiding unnecessary work and expense.
