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.

For a 12x20-foot (240-square-foot) deck, you can expect to pay between $7,200 and $14,400. This cost is based on a general price of $30 to $60 per square foot. The final price will depend on factors such as the decking material, design complexity, deck type, location, and local labor costs. Keep in mind that add-ons will increase the total; for example, adding an under-deck drainage system to a deck of this size could cost an additional $7,700.

Decks are generally more expensive to build because they require elevating and railings. The difference between decks and patios is that decks are elevated, while patios are usually on the ground level. Plus, decks are usually made of wood and need more maintenance than most patios. However, decks and patios serve the same purpose, providing outdoor space for you to enjoy.

Pressure-treated decks last 15 to 20 years on average, but with proper maintenance, you could get 40 to 50 years of value from yours. Reseal your deck every one to two years, and replace old or rotted wood as soon as possible to avoid structural damage. Where you live plays a role in the lifespan of your deck. Intense sunlight, rainfall, wind, and hail can reduce the deck’s lifespan.
