A loose stair railing is a safety hazard. Fix it immediately.
What Causes a Loose Railing? Loose bolts, worn wood, or damaged mounting hardware.
Step 1: Identify which part is loose — the post, the rail, or the wall mounting.
Step 2: Tighten all visible bolts and screws first.
Step 3: For a wobbly post, inject wood glue into the joint and clamp overnight.
Step 4: For wall-mounted railings, replace with longer screws into wall studs.
