Deck inspections focus on safe attachment to the house, structural condition, railings, and signs of rot. A deck that looks fine can still be unsafe if the ledger board is poorly attached.
Decks are exposed to sun, snow, and moisture, so wood can dry, crack, or rot. Composite decking resists rot but depends on a sound frame underneath.
| Key point | What it means |
|---|---|
| Ledger board | The beam that connects the deck to the house, with proper bolts and flashing. |
| Posts and footings | Should be solid and properly supported. |
| Joists and beams | Look for rot, cracks, and sagging. |
| Stairs and railings | Typically 36 to 42 inches high depending on code, with secure balusters. |
Wobbling when you walk, loose railings, soft spots, rusted or missing fasteners, and gaps where the deck meets the house. Decks built without a permit may lack proper construction, so ask for permit records.
Concrete patios can also crack or tilt toward the house. Sloping flatwork can send water toward the foundation, so note the direction of drainage.
