How much does a deck cost?

There’s a lot that factors into your deck’s bottom line—including your location, the materials you choose, whether or not you hire a contractor, and much more. If you’re planning a DIY project, our materials calculator can help you budget. But if you plan to hire a contractor, only they can give you a true estimate.

Deck-building costs by category

Baseline building cost summary

Substructure

If you’re replacing an existing deck, you’ll already have a substructure in place and will likely only need to pay for repairs or expansion if you’re planning for a larger deck. For a from-scratch deck build, the cost of materials and labor to build the substructure can be more than one third of your total costs.

Decking and railing materials

Today’s decking products give you nearly endless options, and prices can vary widely. TimberTech Composite and Advanced PVC lines offer durable, natural wood looks without the maintenance of wood, and railing options to give you even more customization options. Plus, they’re all backed by industry-leading warranties.

Labor

If you decide to work with a contractor, their labor will make up a big portion of your overall deck costs. Working with a registered TimberTech contractor comes with the added benefit of our Replacement Labor Warranty.

Fasteners

Sometimes the things you can’t see can make a big difference. Our proprietary fastening systems are designed exclusively for TimberTech decking.

Additional cost considerations

Beyond the basic costs common to all decks, there are a number of things that can impact the cost of your deck—some that are within your control and some that are not.

Size

Even a few feet can mean a dramatic change to your costs—for both materials and contractor labor.

Design complexity

When it comes to designing your dream deck, the details do add up—from intricate board patterns and unique deck shapes to multi-level designs.

Lighting & extras

From lighting that sets the mood to staircases that transition seamlessly into your green space, extras increase your bottom line. But it’s these touches that really elevate your deck design and make it everyone’s favorite place to hang out—so they can be well worth the added investment.

Site prep

Will your build site need significant clearing or leveling before construction can begin? If so, it might add to your costs.

Permits

Depending on your area, you may be required to purchase a building permit for deck construction.
