What happens here

Attach the ledger board directly to the house using 5-inch lag bolts. These are robust fasteners that require significant torque. Use either an impact driver or a hammer drill for this task, as both tools provide the necessary power. It is highly recommended to pre-drill all holes to prevent splitting the wood. If your house has stucco siding, you will need a concrete bit to drill through it before driving the lag bolts. Importantly, ensure that the space where the ledger board meets the house is properly sealed with caulk or flashing (or both) to prevent water intrusion and subsequent rot.

Goal: Securely attach the ledger board, which supports the deck, to the house.

to make room for this. The ledger board has to be attached to the house using a 5 in lag bolt. This is a beefy piece of hardware. To do that, you're going to want something that can handle more torque. Frankie, you got an impact driver in one hand, right? Right. And you've got a hammer drill in the other hand. Correct. Either one of those will be able to handle the amount of torque that you've got to give because you're driving that ledger board which attaches the entire deck to the house into the rim joist of the structure. Is that right? Correct. When you get to this point, guys, you may want to pre-drill your holes. The reason you want to pre-drill the holes is you don't want to split that wood. And also, I pre-drilled these holes because there was stuckle on the house cuz I had to use a concrete bit to go through the stuckle. The ledger board attaches to the house. But here's something a step that most people miss. They leave this space and it doesn't look like that big of a deal, but what happens is water comes down here, hits this board and goes behind the board and it can't breathe, right? And it will rot easier. Right where the deck meets the house, that space needs to be cocked or flashed or both. What are you at? 16 in on center,
