Adding a mobile home deck is a wonderful way to be creative and enjoy the outdoors. Here are some simple steps to attach a deck to your mobile home. Choose a dry, sunny day for your project so that you can complete it without interruptions. Once you pick a day, follow these simple steps to add a deck to your mobile home.

Step 1 - Check the Surface

Before you start attaching a deck to your mobile home, thoroughly clean the deck surface as well as the exterior wall. It is critical that both surfaces are free of dirt, mold, grease, wood fragments, and mildew. Any decay or rot should be attended to promptly. If you need to wash any of the surfaces, make sure they are absolutely dry before you continue your project.

Step 2 - Cut the Ledger Board

Bolt a ledger board to the side of the home. Make sure the board is treated. Once you have measured the space under your door, cut the ledger board accordingly. Try mock fitting the board and make sure you have the correct length. You will also need to leave some space between the home and the deck so that rain and snow can be diverted easily. Use galvanized fasteners to attach the ledger board to the mobile home.

Step 3 - Secure the Ledger Board

Since ledger boards are seldom straight, you may want to use a flat bar to straighten them as you attach them. Drill slots through the ledger board and the sheathing into the house itself. Attach the ledger board securely using 2 lag screws between each pair of joists. The more joists you use, the more stable the deck attachment will be. Use enough caulk to protect the holes from moisture. Use a hammer and drive the lag screws into the frame of the house.

Step 4 - Weather Proof It

Use silicone caulk to seal all of the gaps. Go over the entire deck, especially joints, nail slots, and ends. If you plan to paint your deck, then check if the sealant you have used is compatible with the paint. To protect the ledger board from both the top and behind, use galvanized metal z-flashing.

Step 5 - Finish Up

Cut and sand any extra ends of the ledger board using a saw for an even, sharp edge. Check thoroughly for any unsealed gaps. Once your sealant is dry, walk on the deck to test the attachment and its stability.

Your mobile home deck is now ready to go. Wait for it to dry completely and keep an eye on your attachments as you start furnishing and decorating it.
