Assess Existing Stairs and Planning

What happens in this clip

Before commencing any structural work, it's crucial to thoroughly assess the existing stair structure. The video highlights that these stairs previously had carpet, which implies a need for meticulous cleaning of staples, tack strips, and adhesive residues. The goal is to prepare the sub-structure for new, solid wood treads and risers, which will eventually be stained. The existing treads may have a 'lip' that needs to be addressed for a flush finish with new components.

Goal: The video begins by showcasing the stairs in their pre-renovation state, emphasizing the significant preparation needed. The stairs previously had carpet, which has been removed, revealing existing wooden treads and risers, some of which are likely painted or previously finished.

About the full video

This video details the extensive preparation required for a stair renovation, focusing on structural modifications and surface readiness before any finishing work, such as applying oil-based stain. It covers removing existing carpet and its residue, modifying baluster heights, and reinforcing the structure for new posts and treads.

Step 1 of 6: Inspect Existing Stair Structure

Begin by carefully inspecting the existing outdoor stairs. Look for any signs of rot, structural damage, loose railings, or uneven surfaces on the current treads. Note the material of the existing treads (e.g., wood, concrete, composite) and how they are attached. This initial assessment will inform the measurement process and highlight any potential issues that need to be addressed before installing new treads.
