• Ledger attachment and flashing — the number one deck failure point
• Structural connectors, joist hangers, and approved fasteners
• Pressure-treated lumber, composite decking, and fastener compatibility
• Guardrail and handrail height, spacing, and load requirements
• Stair stringer layout, rise and run, and landings
• Board replacement, rot repair, and deck resurfacing
• Fence post setting: concrete, gravel, and frost depth
• Gate building, sag correction, and hardware selection
• Cleaning, sealing, staining, and maintenance schedules
