Learn to Talk the Talk Like a Pro
Here's a quick deck components refresher with names and definitions so you sound like you know what you are talking about when you speak to a contractor or walk into the lumber store.
Being able to refer to a specific deck component - like a pier, footing, rim joist, or cantilever - makes it easier for everyone to understand each other.
Every trade or profession seems to have their own language to communicate effectively with. Deck building is no different.
