If you’re thinking about upgrading your outdoor space, composite decking is a fantastic choice. It’s durable, low-maintenance, and looks great year-round. But before you dive in, it’s smart to get a clear picture of the costs involved. Understanding the expenses upfront helps you plan better and avoid surprises down the road. So, let’s break down everything you need to know about composite deck costs and installation.


Breaking Down Composite Deck Costs


When it comes to composite decking, the price tag can vary quite a bit. Several factors influence the overall cost, and knowing these can help you make informed decisions.


Material Costs


Composite decking materials usually cost more than traditional wood, but they pay off in the long run. On average, composite decking boards run between $30 and $45 per square foot, including the price of the boards themselves and the necessary fasteners. The price depends on the brand, color, and quality of the composite material you choose.


Some popular brands like Trex, TimberTech, and Fiberon offer a range of options, from budget-friendly to premium. Higher-end composites often come with better warranties and enhanced durability, which can be worth the extra investment.


Labor and Installation


Labor costs can vary depending on your location and the complexity of the deck design. For a straightforward installation, expect to pay between $8 and $15 per square foot for labor. If your deck has multiple levels, built-in seating, or intricate railings, labor costs will increase.


If you’re a DIY enthusiast, you can save a lot by installing the deck yourself. Just keep in mind that composite decking requires specific tools and techniques, so be sure to research or get some expert advice before starting.


Additional Costs to Consider


Besides materials and labor, there are a few other expenses that might pop up:


  • Deck framing: If your existing frame is damaged or not up to code, you’ll need to repair or replace it.

  • Permits: Some areas require permits for deck construction, which can add to your budget.

  • Railings and stairs: These are often priced separately and can add several hundred to a few thousand dollars depending on style and materials.

  • Site preparation: Clearing, leveling, or grading the site might be necessary before installation.


What Influences Composite Deck Costs?


Understanding what drives the price can help you control your budget better. Here are the main factors that influence composite deck costs:


Size and Shape of the Deck


The bigger the deck, the more materials and labor you’ll need. Also, complex shapes with curves or multiple levels require more cutting and fitting, which adds to labor time and waste.


Type of Composite Material


There are different types of composite decking:


  • Capped composite: Has a protective outer layer that resists fading and staining.

  • Uncapped composite: Usually cheaper but less durable.

  • PVC decking: Made entirely of plastic, often more expensive but very low maintenance.


Choosing the right type depends on your budget and how much wear and tear your deck will face.


Installation Complexity


If your deck requires custom features like built-in benches, lighting, or unique railings, expect higher labor costs. Also, decks that are elevated or have difficult access points can increase installation time.


Location and Contractor Rates


Labor rates vary by region. In Utah, for example, you might find competitive pricing compared to larger metropolitan areas. It’s always a good idea to get multiple quotes from local contractors to find the best deal.


How much does a 20x20 Trex deck cost?


Let’s get specific. A 20x20 deck is 400 square feet, which is a common size for many backyards. Using Trex composite decking as an example, here’s a rough estimate:


  • Materials: Trex decking boards typically cost around $35 per square foot. For 400 sq ft, that’s about $14,000.

  • Labor: Installation might run $10 per square foot, so $4,000.

  • Additional costs: Railings, stairs, and permits could add another $2,000 to $3,000.


Total estimated cost: $20,000 to $21,000.


Keep in mind, prices can vary based on your specific choices and site conditions. But this gives you a solid ballpark figure to work with.


Tips to Save on Composite Deck Installation


While composite decking isn’t the cheapest option upfront, there are ways to keep costs manageable without sacrificing quality.


  • Plan your deck size carefully: Bigger decks cost more, so think about how much space you really need.

  • Choose simpler designs: Straightforward layouts are easier and cheaper to install.

  • Shop around for materials: Local suppliers like Wasatch Deck and Rail Supply offer competitive prices and expert advice, which can save you money and hassle.

  • Consider DIY for parts of the project: If you’re handy, you might install the decking boards yourself and hire pros for framing or railings.

  • Buy in bulk: Purchasing all your materials at once can sometimes get you discounts.


Why Composite Decking is Worth the Investment


Sure, the initial cost might seem high compared to wood, but composite decking offers long-term value:


  • Low maintenance: No need for sanding, staining, or sealing.

  • Durability: Resistant to rot, insects, and fading.

  • Eco-friendly options: Many composites use recycled materials.

  • Aesthetic appeal: Comes in a variety of colors and textures that mimic real wood.


When you factor in the time and money saved on upkeep, composite decking often ends up being the smarter choice.
