Why do floorboards creak? A quick explanation
Before we show you how to fix creaky floorboards, it’s important to understand why floorboards creak. This will help you better understand how to fix it.

To fix creaky floors, first identify the floorboards causing the issue.
Once you have identified the offending floorboard (or floorboards!) it is time to fix the issue. If you have access to the area beneath the floorboards, there are a few things you could try to stop the creak:
Using a caulking gun, insert construction adhesive into the gap between the joist and subfloor, eliminating the movement that causes the creaks and squeaks.
If the joist is warped or deteriorated, open up the space between the joist and the plywood subfloor, then install a length of wood alongside the joist.
If two floor joists are causing the issue, install wood blocking between them. Ensure it fits snugly, but not too tightly, preventing both joists from moving.
The quickest and easiest way to stop the movement is to drive short screws through the underside of the subfloor to the bottom of the finished flooring to hold it in place.
If you don’t have access to the area beneath the floorboards, you could try lubricating the area. This can be done using the following steps:
Sprinkle corn starch or talcum powder into the joints between your floorboards.
Place a clean, dry cloth or rag over the boards.
Walk back and forth over the top of the cloth. This will work the powder into the cracks.
The powder works as a lubricant, reducing wood-on-wood friction.
Don’t forget to vacuum any remaining powder from the floor.
