Assess Damage & Prepare for Repair

What happens in this clip

Begin by thoroughly inspecting the exterior stair structure. Identify any treads or risers that are loose, cracked, splintered, or show signs of rot. Note how the treads and risers are currently attached to the stringers (e.g., using wedges, nails, or other fasteners). The video highlights that original wedges often loosen, fall out, or become damaged, leading to instability. Determine if a full tread replacement is necessary, or if reinforcement of existing, salvable treads/risers is sufficient.

Goal: Examine the existing stair structure to identify loose, rotted, or damaged treads, risers, and stringers. Understand the current fastening method and prepare the area for replacement or reinforcement.

About the full video

This guide provides various methods for repairing and reinforcing exterior stair treads, focusing on replacing damaged components with durable pressure-treated lumber. It covers techniques for reinforcing tread and riser connections, adding structural support, and using threaded rods to tighten the entire assembly, ensuring longevity and resistance to moisture and decay.

Step 1 of 9: Assess Existing Staircase Condition

Examine all treads, risers, and the central support pole for any signs of rust, rot, or damage. Check the stability of each tread by applying firm pressure. Inspect the railing and balusters for looseness or damage. Note any areas that require cleaning, sanding, or minor repairs.
