I've never built an outdoor deck before. How do I build one?
assistant
1. First, decide where you want your deck to go and create a plan.
2. Next, make sure your plan is up to code and that you have the correct permits and permissions to build it.
3. Now it is time to excavate the area where you will build the deck.
4. Once the excavation is finished, pour the concrete footings and posts and let them cure for at least 24 hours.
5. Next, add the joists and make sure they are level and secure.
6. Then attach the deck boards to the joists, making sure they are secure and not warped.
