Deck installation costs will depend on what type of decking materials you use and if you hire a contractor or build the deck yourself. The cost for the understructure should be the same for both composite and wood decking. The real cost difference comes when you compare the cost of the planks. Green Plank® low-maintenance composite decking boards are very easy to install. When all is said and done, Green Plank® composite decks cost about 25% more to construct than wood decks.
Installation costs for any deck are quoted for basic models before any enhancements or improvements are added in. Another deck enhancement that will raise deck installation cost is having electrical service like outlets or lighting added. Yet another deck cost raiser is having a retractable awning to provide shade installed over the deck.
