Deck Building Costs

Decks provide a transition from indoor to outdoor spaces, providing you and your family a place to enjoy the outdoors from the safety of your home. To determine the overall price of building a deck, consider these main cost factors.
  1. Landscaping and Construction

    • Building a deck near your home may require you to perform some landscaping or minor construction to ensure that the deck is level and stable, especially if you plan on building the deck on an incline or decline. These complications may require you to build a multilevel deck with stairs or ramps, which costs upwards of $25,000, according to Cost Helper.

    Deck Size

    • A small, 120-square-foot deck comprised of pressure-treated wood, capable of being built yourself, costs as low as $500. In contrast, a larger, 400-square-foot deck built by a professional costs around $10,000, as stated on Cost Helper.

    Material Quality

    • The material used to build your deck greatly contributes to the price. For example, pine wood costs less than cedar wood, but the quality isn't as great; whereas plastic-wood composite material is durable and low-maintenance but costs $20 per square foot.
