How to attach a deck to a house effectively and securely?

To attach a deck to a house effectively and securely, you should first ensure the ledger board is properly installed and flashed to prevent water damage. Use lag screws or bolts to attach the ledger board to the house framing, making sure it is level and securely fastened. Install joist hangers to support the deck joists and use appropriate fasteners for the decking material. Regularly inspect and maintain the deck to ensure its stability and safety.
