Composite decking requires a solid foundation or substructure for support. This base is typically a frame composed of posts, beams, joists, and footings. The frame can be built from various materials, such as composite, plastic, timber, or metal, depending on your budget, deck type, and environmental conditions. For maximum stability, a professional deck builder may recommend installing this frame on top of a solid concrete base. It is best to discuss the most suitable substructure design and materials for your specific project with a professional.

Local building codes don’t specify the number of steps a deck can have before a railing is required, mainly because stair height varies widely. Most areas require decks 30 inches or higher to have a railing. While not exact, that roughly equates to four to seven steps.

Composite decking might cost more upfront, but it delivers value in terms of durability. Unlike wood, composite material resists common deck problems such as rotting, fading, warping, and all the other things you don’t want a deck to do. The extra processes lead to a higher price tag, but you’ll save big in maintenance costs down the road.

In general, you need a footing at each corner of your deck, and within 8 feet of each other. So, how many you need depends on the size and shape of your deck, plus any local building codes. It also depends on factors like the load capacity of your soil and the weight of your deck. You can find a footing calculator online or contact a pro for support.
