Repair options depending on the cause
| Symptom | Likely cause | Typical remedy |
|---|---|---|
| Single board squeaks underfoot | Loose nail fixing to joist | Re-fix with screws through board into joist |
| Whole area creaks, boards feel slightly springy | Joist movement or undersized joists | Investigate joist condition, may need bridging or sistering |
| Squeak along a board edge, not a fixing point | Board-to-board friction, loose tongue and groove | Screw fix and lubricate or shim the joint |
| Squeaking worse in damp weather | Timber swelling from moisture, suspended floor ventilation issue | Check subfloor ventilation and moisture before re-fixing |
