Build better stairs
Simple notched stair jacks are fine for interior stairs. They get nailed to wall studs for stability and are hidden once the house is finished. Not so with deck stairs. Naked, notched treated-wood stair jacks are unattractive and wobbly, and because there isn’t much meat to attach posts or pickets to, you’ll have wobbly handrails, too. But it’s easy to strengthen them and spruce them up. Adding sturdy, solid 2×12 skirts to the outside jacks and stair risers does it all.
