Step 2 · Prepare Shim Material

Examine the area where the squeak originates. You'll likely see a small gap between the tread and riser, or between these components and the staircase stringer. Using a utility knife or a handsaw, cut thin pieces of wood (like scraps from 1x lumber or pre-made wood shims) that are slightly longer than the gap. The goal is to create pieces that can be tapped into these gaps to eliminate movement.
