You will need a drill, wood screws, wood shims, and construction adhesive.

Step-by-Step Guide to Silencing Squeaky Floors

1.Locate the Squeak: Have a helper walk on the floor above to pinpoint the exact location of the floor squeaks. Mark the spot on the joist below.

2.Use Shims: If there is a small gap between the subfloor and the joist, gently tap a thin wood shim into the gap. Be careful not to lift the floor too much.

3.Use Adhesive: For a more permanent fix, apply a bead of construction adhesive between the subfloor and the joist where the squeak occurs.

4.Screw the Subfloor: If shims and adhesive aren't enough, drive a screw up through the joist and into the subfloor (but not through the finished floor above).

5.This DIY home repair guide is an effective way to eliminate floor noise and is a simple home maintenance task.
