Deck building is a fairly simple process. Digging and setting posts and constructing a level, steady frame are projects that most homeowners can handle. There is one piece of the puzzle that can seem a little intimidating without all of the information, attaching your deck to your brick house with a ledger board. Ledger boards serve as the outside, or rim joist in a deck frame. Proper installation is essential for a long lasting, level deck.
Cut your ledger board to the required length. It will need to be as long as the edge of the deck attaching to the house. Typically deck ledgers are made from 2 inch by 6 inch or 2 inch by 8 inch treated lumber. Use a mitre saw, or circular saw to make the cut.
Mark the ledger where the framing joists will be connecting to it. Most decks are built with 16 inch or 24 inch spacing between rows of framing. If you are using joist hangers it is best to add them before installing the ledger.
Drill a pilot hole between the placement for each joist using a ¼ inch wood bit. Make sure the hole goes through as straight as possible and stick to centre of the board, for strength. Countersink each hole to allow for the head of the concrete screw to run flush with the face of the ledger.
Determine the height of your deck where it meets the house. Mark both ends. Use a level, set on top of your ledger, to double check for correct pitch, by holding the ledger against the wall in its correct position.
Hold the ledger in place and use a 3/16 mason's bit to drill through each ¼ inch pilot hole in the ledger into the face of the brick, 1/8 inch deep. These will serve to mark the placement of the pilot holes. Be sure to get the right mason's bit. For a standard drill, or impact driver a rotary mason's bit is used. For a hammer drill a percussion mason's bit is required.
Set the ledger board aside and drill a pilot hole in the brick at each point you marked with the drill in the previous step to a depth of 1 ¾ inches. Use masking tape wrapped around the mason's bit 1 3/4 inches from its tip for an easy visual depth reference. Blow the brick dust from the holes.
Hold the ledger board in place and starting at one end, drive a ¼ by 3 inch tapcon style concrete screw through the ledger into the pilot holes in the brick. Be sure to drive your screws in until they are flush with the face of the board. Repeat with each hole.
