Step 6 · Address Sub-Surface Creaks

If the popping noise persists after addressing carpet adhesion, the issue may be with the wooden stairs themselves. Carefully inspect the wooden treads and risers for any visible cracks, loose boards, or signs of movement. Tap on the wood to listen for hollow sounds indicating looseness. You may need to access the underside of the stairs if possible (e.g., from a basement or attic) to drive screws or shims into the joists or stringers where the treads are attached.
