How to Fix a Squeaky Floor

That annoying creak every time you walk across the landing at night. Squeaky floors are one of the most common household annoyances, but they are almost always fixable in under an hour with basic tools.

What Causes Squeaks

Floorboards squeak when they rub against each other or against the nails/screws holding them down. This happens because: wood shrinks as it dries out over years, nails work loose from joists, or the subfloor was never properly secured in the first place. The squeak is friction — eliminate the movement and you eliminate the noise.

Method 1: Screw Down (Best Fix)

Tools: Cordless drill, 40mm wood screws, stud finder or joist detector. Time: 20 minutes.

Locate the joist beneath the squeaky board — tap along until the sound changes from hollow to solid, or use a stud finder. Drive two screws through the floorboard into the joist at slight angles to each other. The screw heads should sit just below the surface. This pulls the board tight against the joist and stops all movement.

Method 2: Talcum Powder (Quick Fix)

Sprinkle talcum powder or powdered graphite into the gaps between squeaky boards. Work it in with your foot. This lubricates the edges where boards rub together. It is a temporary fix that works well for surface-level squeaks between boards rather than board-to-joist issues.

Method 3: PVA Glue

For boards that have slight movement but you cannot access from below, squeeze PVA wood glue into the gap between the board and the joist. Place heavy weights on top overnight while it dries. This fills the gap and bonds the board in place.

Carpeted Floors

You do not need to lift the carpet. Special breakaway screws (like Squeak No More kits) drive through carpet and snap off below the surface. Or, locate the joist, drive a screw through the carpet into the joist, then work the carpet pile back over the screw head with your fingers.

When to Call a Professional

If the entire floor bounces or squeaks extensively, you may have a structural issue — damaged joists, inadequate support, or rot. If you can see or feel the floor deflecting significantly when walked on, get a structural survey before attempting DIY fixes.
