Will Refinishing Hardwood Floors Silence Squeaks? The Answer May Surprise You!
That unmistakable sound—the persistent creak or squeak every time you walk across a certain spot on your hardwood floor. It’s a sound that can break the quiet of a peaceful morning or announce your late-night trip to the kitchen to everyone in the house. It’s a common problem, and one that often leads homeowners to wonder if their planned refinishing project might be the two-for-one solution they’ve been hoping for.
You imagine beautifully smooth, gleaming floors that are also blissfully silent. But will sanding, staining, and sealing the surface of your wood floors actually stop them from squeaking? The short answer is, refinishing alone will not stop your floors from squeaking.
While refinishing can solve many aesthetic issues, it doesn’t address the root causes of a noisy floor. To truly achieve silence, you need to understand why your floors are making noise in the first place.

Why Your Hardwood Floors Are Squeaking in the First Place
A squeaky floor is fundamentally a problem of movement. The noise you hear is the sound of friction, created when pieces of wood rub against each other or against a fastener, like a nail or screw. This movement can happen between floorboards, between the floorboards and the subfloor, or between the subfloor and the underlying floor joists.
Understanding the source of this movement is the key to solving the problem. Several factors can contribute to a noisy hardwood floor, turning your peaceful home into a symphony of creaks.
Common Culprits Behind Noisy Floors
Seasonal Changes: Wood is a natural material that reacts to its environment. During dry winter months, the wood in your flooring can shrink, creating small gaps. In the humid summer, it expands. This constant cycle of expansion and contraction can loosen boards and create noise over time.
Subfloor Issues: An uneven or improperly installed subfloor is a major cause of squeaks. If there are gaps between your hardwood planks and the subfloor, the boards will move and make noise when you walk on them. The quality of the subfloor sheathing is critical; for instance, choosing the right thickness, such as in a 19/32 vs 5/8 OSB comparison, can impact the floor’s long-term stability.
Joist Problems: Floor joists are the structural beams that support your floor. Over time, gaps can form between the subfloor and the joists. When you step on that spot, the subfloor moves down to meet the joist, causing a squeak. Warped or shrinking joists are often to blame for this issue.
Improper Installation: Sometimes, the problem dates back to the day the floors were installed. Insufficient nails or adhesive can leave floorboards without the secure attachment they need, allowing for movement and noise. Considering professional installation is key, though understanding the factors that influence the final price, like those detailed in analyses of Lumber Liquidators installation costs, can help you budget effectively.
The Hard Truth: Will Refinishing Alone Stop the Squeaking?
The process of refinishing a hardwood floor involves sanding down the top layer to remove the old finish and any surface-level imperfections. After sanding, a new stain and protective topcoat are applied. This process does wonders for the appearance of your floors, erasing scratches and restoring their original luster.
However, this entire process is cosmetic. Refinishing does not address the structural movement that is the true cause of squeaks. The sanding machines, stains, and polyurethane finishes only treat the surface of the wood. They do not add structural support, fill gaps between the subfloor and joists, or secure loose planks to the subfloor.
In some very rare cases, a new finish might temporarily quiet a minor squeak by seeping into a seam and acting as a lubricant, but this effect is minimal and will not last. The underlying movement will persist, and the squeak will inevitably return.
The Real Solutions: How to Actually Silence Your Squeaky Floors
Now for the good news: you don’t have to live with squeaky floors. There are several effective methods to silence them for good. The best approach depends on the source of the squeak and whether you can access the floor from below (through a basement or crawlspace).
Step 1: Pinpoint the Source of the Squeak
Before you can fix the problem, you have to find its exact location. Have a helper walk slowly across the noisy area while you listen carefully. If you have access to the floor from below, have them walk above while you are in the basement or crawlspace to see if you can spot any movement in the subfloor or between the subfloor and joists.
Step 2: Choose Your Method of Attack
Once you’ve located the squeak, you can choose from several repair methods. Some can be done from above the floor, while others require access from below. Fixes from below are generally more permanent and effective.
From Above (The Easier Fixes)
These methods are less invasive and can often be done without major disruption. They are best for squeaks caused by friction between floorboards.
Lubricating the Seams: For minor squeaks between planks, a dry lubricant can sometimes help. Sprinkling powdered graphite or talcum powder into the seams and working it in can reduce friction. This is often a temporary fix but can provide immediate relief.
Specialized “Squeak-Ender” Kits: Hardware stores sell kits designed to stop squeaks from above. These typically involve a special tripod fixture and scored screws. You drive a screw through the floorboard and into the subfloor, and the fixture is designed to snap the screw head off just below the surface, leaving an easily concealable hole.
From Below (The More Permanent Fixes)
If you can get under the floor, you have access to more robust and lasting solutions that address gaps between the subfloor and joists.
Shimming the Gaps: A very common and effective method is to insert thin, wedge-shaped pieces of wood called shims into any gaps between the subfloor and the joists. Coat the shim with carpenter’s glue and gently tap it into the gap until it’s snug, but be careful not to hammer it in so far that you lift the floorboard.
Applying Construction Adhesive: For longer gaps along a joist, you can apply a bead of construction adhesive into the seam where the subfloor meets the joist. This glues the two components together, preventing movement and noise.
Adding Wood Blocks for Support: Another excellent method is to screw a piece of 2×4 or 2×6 lumber along the side of the joist, snug against the subfloor. This provides additional support and stability to the subfloor in the squeaky area.
| Repair Method | Best For | Difficulty Level | Permanence |
|---|---|---|---|
| Powdered Lubricant | Minor friction between boards | Easy | Temporary |
| Squeak-Ender Screw Kit | Loose boards (from above) | Easy to Moderate | Permanent |
| Wood Shims | Small gaps between subfloor & joists (from below) | Moderate | Permanent |
| Construction Adhesive | Long gaps between subfloor & joists (from below) | Moderate | Permanent |
| Support Blocks/Cleats | Warped joists or larger unsupported areas (from below) | Moderate to Hard | Very Permanent |
The Perfect Pairing: Combining Refinishing with Squeak Repair
While refinishing won’t fix squeaks on its own, the time of a refinishing project is the absolute best time to address them. The furniture is already out of the room, the floors are cleared, and you’re already focused on improving your flooring. This is the golden opportunity to solve both problems at once.
Fixing squeaks from above with specialized screws is much easier before sanding. Any small holes created by the screws can be filled with wood putty and then sanded perfectly smooth and flush with the rest of the floor. Once stained and finished, the repair will be virtually invisible.
Questions to Ask Your Flooring Contractor
Many professional flooring companies offer squeak repair as an add-on service to refinishing. When getting quotes, be sure to ask:
Do you offer squeak diagnosis and repair?
A reputable contractor will be able to help you identify the source of the squeaks.
What methods do you use to fix them?
This will help you understand their approach and whether they are equipped to handle your specific issue.
How will this impact the overall cost and timeline?
Getting a clear idea of the additional investment in time and money will help you make an informed decision.
When is it Time to Call in the Big Guns?
Most floor squeaks are annoying but harmless. However, widespread, excessive squeaking, especially when combined with sagging or bouncing floors, can be a sign of more serious structural issues. Problems with the foundation or main support joists require more than a simple DIY fix.
If you suspect a larger structural problem, it’s wise to consult a structural engineer or a general contractor for a thorough assessment. Just as a poorly placed corner lot fence can cause property line disputes, ignoring potential structural issues with your floor can lead to much bigger headaches down the road.
Prevention: How to Keep Your Floors Quiet for Years to Come
Once your floors are silent, you’ll want to keep them that way. One of the best preventative measures is to maintain a consistent humidity level in your home, ideally between 40% and 60%. Using a humidifier in the dry winter months and a dehumidifier during the humid summer can minimize the wood’s expansion and contraction, reducing the likelihood of future squeaks.
The Final Verdict on Refinishing and Squeaks
To put it simply: refinishing is for beauty, not for silence. It is a surface treatment that can make old, worn floors look brand new, but it lacks the structural impact needed to stop squeaks.
The real solution lies in identifying and stabilizing the movement within your floor system. The most efficient and effective approach is to combine these structural repairs with your refinishing project. By tackling the squeaks before you sand and stain, you ensure that the end result is a floor that is not only beautiful to look at but also a pleasure to walk on—silently.
