Generally speaking, there are two types of decks: freestanding and attached. The former are also called floating, and refer to standalone decks that aren’t connected to another structure. Attached decks are built directly onto homes or other buildings. A ledger board is used to facilitate this attachment.

How does it work?

A ledger board is typically a 2×8 piece of pressure treated lumber. It is attached to the house with lag screws or expansion anchors, depending on whether the connection is to the house rim joist or the basement wall. Once the ledger board is secured the deck is built off of it.
