Step 4 · Attach Stringers to Porch and Ground
Position the stringers against the porch landing. For attachment to the porch, use sturdy metal brackets or toenail screws/nails into the porch frame. Ensure the stringers are plumb and level. At the bottom, the stringers should rest on a solid foundation. This could be a concrete pad, pre-cast concrete blocks, or pressure-treated 4x4 posts set in concrete. Secure the stringers to this base using appropriate fasteners.
