Step 2 · Inspect and Repair Staircase Structure

Examine all wooden components for signs of decay, insect damage, or structural compromise. Pay close attention to the areas where treads meet stringers and risers. Any loose connections should be re-secured with screws or construction adhesive. Damaged sections may require patching or replacement with new wood. Ensure the sub-treads are level and sound. If the sub-treads are in poor condition, they may need to be replaced or covered with a plywood layer.
