How to troubleshoot a Squeaky Floorboard
Squeaky floorboards are caused by movement between the board and the joist. This guide covers fixing them from above with screws or from below with blocking.
Step-by-Step Fix
- Locate the squeaky area by walking on the floor and listening for the noise.
- From above: locate the floor joists using a stud finder or by measuring standard joist spacing (16 inches or 24 inches).
- Drill pilot holes through the floorboard and into the joist.
- Drive a countersunk screw into the joist, ensuring the head is below the floor surface.
- Fill the screw hole with wood filler and finish with a matching stain or paint.

Common Error Codes
| Code | Meaning | Resolution |
|---|---|---|
| Squeak returns | Screw missed the joist | Move the screw slightly and try again, ensuring it hits the joist. |
