Understanding the cost of a deck​

Building a deck is an exciting project—but with so many options, you may be unsure of how to budget for it. From the design complexity and structural requirements to the materials you use, there are a lot of factors to consider. Our Deck Material Cost Calculator below can help you determine the deck material cost, which is only one component of the overall project cost. Here, we’ll breakdown the cost of a deck project, share the cost of an ”average” deck, and walk you through the lifetime value of an investment in TimberTech over wood.​

The cost of an “average” deck​

There are a few factors that can drive the total project cost up or down—including the size and complexity of the deck, where you live, the contractor you choose, the landscape of your property, permit fees, and the features included like stairs or lighting. Here, we provide a snapshot of the cost of an average 16×20 foot deck for reference, but keep in mind that a more elaborate deck project can reach more than $100,000.​

For example:

16×20 = 320 sq. ft.

*Cost of deck material varies by collection; see Deck material Cost Calculator below for details.

Long-Term Value

Wood versus TimberTech: lifetime costs​

While a TimberTech deck may cost more upfront, the savings over time are substantial since TimberTech Decking won’t require the same annual maintenance and repairs as a wood deck. The upgrade from a pressure treated wood deck to a composite or PVC deck can add as little as 15% to the total cost of your project even though the boards themselves typically cost 20-40% more. This is because the largest portion of your project, substructure, and labor costs remain the same regardless of the decking material you choose. And if you’re considering premium hardwoods like ipe or cedar, the cost of TimberTech Decking is comparable and often less.​
