The Importance of Deck Inspections: A Home Inspector’s Guide


A home inspector’s insight into the world of decks and what are the main components that are evaluated during an inspection to help understand the process. Assessing the overall condition of the deck, examining the chosen materials most commonly wood, and providing valuable insight into the conditions at the time of the inspection.

Key Structural Components Inspected

  • Foundation and Footings: The inspection begins at the very base – the foundation and footings. Accessing their adequacy to support the deck’s load, ensuring a solid and secure structure.
  • Framing and Support Beams: Framing and support beams are scrutinized for signs of wear, decay, or structural compromise.Close attention to connections and joints, identifying any potential issues.
  • Deck Joists and Ledger Board: Deck joists and the ledger board are inspected for proper spacing, attachment, and secure fastening. Any deviations from standard practices are documented.
  • Connections and Fasteners: The devil is in the details. Bolts, screws, and other connections are scrutinized for tightness and integrity to ensure the deck remains steadfast over time.
  • Flashings: To prevent water damage, flashings, and waterproofing measures, it is important to verify that they are correctly installed and in good condition.
  • Staircase Components: Stairs are not just functional components; they are a potential safety hazard if not constructed properly. Evaluation of the rise, run, and handrail for compliance with safety standards.

In conclusion, CPSC (U.S. Consumer Product Safety Commission) says that in one recent four-year period, there were about 2,900 injuries associated with collapses and failures of porches, decks, and balconies. That’s an average of about 725/year. A home inspection is to bring clarity to the structural integrity of decks in residential properties. Ensuring construction quality, and inspecting key structural components, can contribute valuable insights to real estate transactions, ensuring that buyers and sellers have a comprehensive understanding of the deck’s condition and potential areas of improvement.
