To stop a wood floor from creaking, you must eliminate the movement between the floorboard and the subfloor by securing them tightly together, lubricating the floor, reinforcing the subfloor and addressing humidity issues. However, l
Creaking happens when wood pieces rub against each other due to movement. This is most often caused by changes in home humidity, which makes wood expand and contract, or by the original fasteners becoming loose over time. The ideal environment for a wood floor is a relative humidity between 30% and 50% and a stable temperature between 15.5C and 26.5C (60F and 80F).

Step by Step Process To Stop Wood Floor From Creaking
Step 1: Pinpoint the Exact Location
First, you need to find precisely where the creak is coming from. Walk slowly across the squeaky area while a helper listens from a different angle to identify the specific board or boards causing the noise. Once you find the spot, mark it with a piece of painter’s tape.
Step 2: Choose Your Method Based on Accessibility
Your approach will depend on whether you can access the floor from below (e.g., through an unfinished basement or crawlspace).
Method 1: Securing the Floor from Above (Most Common)
This is the best method if you cannot get underneath the floor. It uses specialized screws that secure the flooring without leaving a visible screw head.
Tools and Materials:
A creak-elimination kit (like “Squeeeeek No More”), which includes special scored screws and a depth-control fixture.
A power drill.
A stud finder.
Procedure:
Locate the Joist: Use a stud finder to locate the floor joist closest to the creak you marked. The most secure connection is made when you screw the floorboard into a joist. Mark the joist’s location.
Set Up the Tool: Place the depth-control fixture from the kit directly over the creak and on top of the joist line.
Drive the Screw: Insert one of the special scored screws into the fixture. Using your drill, drive the screw down through the floorboard and the subfloor, and into the joist. The fixture is designed to automatically stop the screw at the perfect depth, just below the surface of the wood.
Lubricate the Joints: If the creaking is due to friction between the floorboards, try sprinkling talcum powder, baby powder, or powdered graphite into the joints. This will reduce friction and eliminate the creaking sound.
Snap Off the Screw Head: The fixture has a notch that allows you to rock the screw back and forth, snapping the head off at its scored point. This leaves the threaded part of the screw firmly in place while the head is gone.
Conceal the Hole: The process leaves a tiny hole (less than 1/16 of an inch) that you can easily fill with matching wood putty. Once filled, the repair is virtually invisible.
Method 2: Reinforcing the Floor from Below (If You Have Access)
If you have an unfinished basement or crawlspace, you can apply a very sturdy fix from underneath.
Tools and Materials:
Short wood screws (e.g., 1.25-inch).
Power drill.
Wood shims.
Carpenter’s glue or subfloor construction adhesive.
Procedure A: Use Short Screws
Have your helper walk on the floor above to make it creak. From below, you can often see a small amount of movement between the subfloor and the floor joist. Drive a short screw through the subfloor up into the base of the finished floorboard. Be very careful that the screw is short enough not to pierce the top surface of your floor.
Procedure B: Fill Gaps with Shims
If you see a small gap between the bottom of the subfloor and the top of a joist, this can cause a squeak. Apply a small amount of carpenter’s glue to a thin wood shim and gently tap it into the gap until it is snug. Do not force it in, as this could create a new bulge in the floor above.
Procedure C: Apply Construction Adhesive
For a rock-solid fix, apply a long bead of subfloor construction adhesive along the seam where the squeaky subfloor panel meets the joist. When the adhesive cures, it will bond the two pieces and prevent any movement.
How to Fix Squeaky Wood Floors From Above?
To fix squeaky wood floors from above, first pinpoint the area where the squeak occurs. Then, find the floor joists underneath the floor. Next, drill screws through the surface of the floor into the joist to secure the boards tightly. If there are gaps between the subfloor and joist, insert shims to fill the space. For added stability, apply construction adhesive to reinforce the connection between the boards and the joist.
What are the Best Lubricants for Wood Floors?
For squeaky wood floors, powdered soapstone, powdered graphite, or mineral oil work well as lubricants. Simply sprinkle them between the floorboards and help work them in by walking on the area or using a soft brush. Another quick solution is WD-40, which is particularly effective for board-to-board squeaks where pressure can be applied.
Why Do My Wood Floor Squeak When I Walk On Them ?
Your wood floors squeak when you walk on them primarily because of movement and friction. That noise you hear is the sound of different components of your floor rubbing against each other.
Wood is a natural material that expands when it absorbs moisture and contracts when it dries out. This is the most common cause of floor squeaks.
Dry Conditions: During drier seasons or when indoor heating is high, wood loses moisture and shrinks. This shrinkage can create tiny gaps between the floorboards, the subfloor, and the nails or staples holding them down. When you walk on the floor, the boards move into these gaps, rubbing against each other or the fasteners and causing a squeak.
Humid Conditions: In more humid weather, the wood expands. This can cause boards to press tightly against one another. The pressure and friction from this tight fit can also lead to squeaking as the boards move under your weight.
