It also covers protective tape, fasteners, hardware, and any accessories you want to add. Every entry in your breakdown shows the type of material, the quantity needed, and the projected cost, so you can plan purchases with confidence and avoid missing items when it’s time to order.
So, how much does Trex decking cost? Most homeowners can expect a range between $5 and $23 per square foot for materials, depending on the product line. Entry-level boards offer affordability, while premium collections add durability and style.
The trex deck cost calculator accounts for more than just the boards. It factors in fascia, railing, risers, and fasteners when selected. This gives you a clear sense of your expected total before starting construction.
Compared to natural wood, Trex requires less maintenance and has a longer lifespan. While the upfront cost of Trex decking may be higher, many homeowners see long-term savings by avoiding staining, sealing, and early replacement.
Using our Trex deck price calculator lets you view your options side-by-side and make choices that align with your goals, budget, and design vision.
Trex Signature, Lineage & Transcend
These premium lines deliver high-end looks with top-tier performance. Trex Signature offers modern aesthetics with advanced PVC durability. Trex Transcend Lineage combines high-end design with cooling technology for added comfort, while Trex Transcend provides rich color and deep woodgrain patterns.
These options typically fall in the range of $12 – $15 per square foot. Their fade and stain resistance, lifetime performance, and design flexibility make them ideal for luxury builds or homes with complex deck design needs.
Trex Select & Trex Enhance
Trex Select & Select 2.0 offers a balance between value and appearance, while Trex Enhance comes in two subcategories: Basics and Naturals. These collections provide long-term durability at a lower price, making them ideal for budget-conscious builds.
Expect an average cost of Trex decking per sq ft between $5 and $8 for Enhance, and $8 to $13 for Select and Select 2.0. Despite their lower pricing, these collections still use the same composite material core, offering a smart upgrade from pressure treated wood or entry-level wood decks.
When comparing lines, factor in not just board pricing, but also the potential for reduced maintenance and longer life.
That balance impacts the overall costs of your outdoor living space over time.
Several key elements impact labor costs:
- Deck size: Larger decks take more time and materials to build.
- Shape and design: Angled corners, inlays, or built in seating raise complexity.
- Product selection: Some Trex boards require hidden fasteners or more detailed installation.
- Site conditions: Sloped yards, poor soil, or access challenges may increase labor hours.
The Trex deck price calculator gives you a realistic estimate based on your selections. However, actual labor costs depend on your contractor’s rates, location, and timeline. In most regions, homeowners pay between $10 and $15 per square foot for labor alone.
Factor labor into your total cost early in the planning stage to avoid surprises. If you’re aiming for aesthetic appeal or added features like lighting or railings, budget accordingly and communicate clearly with your installer.
Start with size. A larger footprint increases your material costs, especially if you include features like stairs or multiple levels. Add-ons like fascia, risers, and railing also impact your final price. The Trex decking cost calculator gives you the flexibility to see how each option changes your budget.
Next, consider your chosen collection. Higher-end products like Signature or Transcend Lineage come at a premium, while Select and Enhance provide great value for straightforward builds. Matching your design goals with the right product line helps control your deck project budget.
Also think about deck board direction, pattern, and spacing. These details affect how much material you’ll need and how complex the installation becomes. While the calculator adjusts for these variables, understanding them gives you more control over planning and layout.
Your environment matters too. Homes in high-traffic areas or with full sun exposure may benefit from boards with added durability or cooling features. Choosing the right Trex product helps extend the life of your deck and reduces maintenance costs long-term.
Planning your deck starts with the right tools – and the Trex decking calculator makes it easier to take the next step. From estimating board quantities to understanding total price ranges, this tool helps you build a realistic vision for your outdoor space.
Whether you’re designing a low-maintenance upgrade or a premium custom layout, the calculator supports every Trex collection – Signature, Transcend Lineage, Transcend, Select, and Enhance. With just a few inputs, you’ll see how your decisions affect materials, layout, and total cost.
A clear plan makes a better deck. Use the calculator to bring clarity, accuracy, and direction to your next project – before a single board goes down.
A 14×20 Trex deck (280 sq ft) typically ranges from $8,400 to $16,800 for materials only. After adding labor (estimated at 1/3 of material cost), the total project cost may range from $11,200 to $22,400. Use our Trex Decking Calculator to get a personalized estimate for your materials.
For a 16×20 deck (320 sq ft), expect material costs between $9,600 and $19,200. With labor included (1/3rd added), your estimated total cost comes to $12,800 to $25,600, depending on product line and features.
An 18×20 Trex deck (360 sq ft) usually costs $10,800 to $21,600 for materials alone. Including labor, the total cost rises to approximately $14,400 to $28,800.
A 20×20 deck (400 sq ft) averages $12,000 to $24,000 for materials. Once labor is added, your total installed price could be $16,000 to $32,000. Start with the Trex Decking Calculator to plan your full budget.
Your available budget determines your size, material selection, and added features. The Trex deck price calculator helps you test different layouts and product lines before finalizing your plan. For example, if you want a mid-range deck using Enhance or Select, you may build a larger footprint. Choosing Signature or Transcend may reduce square footage but boost durability and curb appeal.
Match your budget with your priorities – whether that’s long-term performance, unique design elements, or a simple surface upgrade. The trex decking cost output will reflect what’s possible within your range.
Many homeowners start by comparing the cost of Trex decking to natural wood or pressure treated wood. Trex has a higher upfront cost but typically pays off over time. Wood requires regular sealing, staining, and repairs, while Trex resists weathering and fading with minimal upkeep.
When using the Trex decking cost calculator, consider the big picture. While wood may seem less expensive at first, annual maintenance adds up quickly. Trex boards also tend to last longer, keeping overall costs lower over time.
Yes, regional pricing and seasonal demand can influence the cost of Trex decking per sq ft. Some homeowners notice price changes during peak building months or in high-demand areas. The Trex deck cost estimator offers a reliable baseline, but for location-specific pricing, factor in local labor rates and retailer availability.
Use the calculator for planning, then check current pricing with your local supplier before finalizing material purchases.
