Remove Old Stairs and Assess Site

What happens in this clip

Begin by removing the old, dilapidated porch stairs. Observe the existing structure to understand previous construction methods and identify areas for improvement. Take measurements of the existing space and desired stair dimensions to plan for the new, stronger stringers and treads. The video highlights that the previous stairs had inadequate spacing for stringers and insufficient tread depth, which needs correction in the new build. The ground where the stairs will land is also exposed for subsequent anchoring.

Goal: The initial phase involves removing the existing porch stairs to clear the workspace and assess the condition of the underlying support structure and ground for the new stair installation. This allows for measurements and planning.

About the full video

This video demonstrates the step-by-step process of rebuilding a set of front porch stairs using pressure-treated lumber for the stringers and composite TimberTech decking for the treads. The project emphasizes robust construction techniques, including closer spacing for stringers and secure fastening methods like deck screws with hidden plugs, and construction adhesive with finish nails for aesthetic trim. While the video focuses on stair construction, the principles of structural support, precise cutting, and secure fastening are directly applicable to deck beam installation, particularly in how loads are transferred to supporting elements and how components are securely joined for long-term integrity.

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.

1. Step 1: Inspect Existing Stair Structure

   • 0:00–0:13 Assess Existing Stairs and Planning
   • 0:00–0:59 Assess Existing Unsafe Staircase
   • 0:00–0:12 Remove Old Stairs and Assess Site (this video)

2. Step 2: Measure Tread Depth

   • 0:31–1:01 Measure Riser Height and Tread Depth Consistency
   • 0:00–0:03 Measure Individual Stair Components
   • 0:55–1:05 Measure and Cut First Tread

3. Step 3: Measure Tread Width

   • 0:21–0:53 Measure Stair Tread Width
   • 0:00–0:03 Measure Individual Stair Components
   • 7:25–8:46 Measure Winder Steps Width

4. Step 4: Measure Riser Height

   • 1:44–2:33 Calculate Riser Height (Option 2) and Verify Code Compliance
   • 1:24–1:56 Repeat for All Risers and Measure Variation
   • 4:32–5:10 Calculate Individual Riser Height

5. Step 5: Check for Stair Squareness and Level

   • 1:11–2:23 Identify and Measure Out-of-Square Deviations
   • 12:00–14:21 Check Tread Level and Stringer Fit
   • 0:18–0:24 Verify Overall Frame Squareness, Plumb, and Level

6. Step 6: Document All Measurements and Irregularities

   • 3:09–4:52 Record All Measurements on Template
   • 0:00–0:03 Measure Individual Stair Components
   • 1:36–2:16 Measure Worn Sections for Code Compliance
