What is Trex Decking?

Trex is a brand of composite decking made from a blend of recycled wood fibers and plastic. Unlike traditional wood, Trex doesn’t rot, splinter, or require staining and sealing. It’s ideal for:

• Backyard decks
• Poolside patios
• Rooftop terraces
• Elevated porches

Trex offers various product lines based on budget and aesthetics, such as Trex Enhance®, Trex Select®, and Trex Transcend®.

Why Use a Trex Cost Calculator?

Trex decks involve many components: decking boards, fasteners, framing, railing, and labor. A Trex Cost Calculator:

• Provides a realistic estimate based on your deck size and product line
• Breaks down costs for materials, labor, and optional add-ons
• Helps compare budget options among Trex tiers
• Guides your decisions before purchasing or hiring contractors

It’s especially helpful if you’re choosing between DIY and professional installation.

Average Trex Decking Costs

Trex deck installation typically ranges from $15 to $38 per square foot, depending on the series and labor involved. Here’s a rough breakdown by product:

• Trex Enhance®: $15–$25 per sq ft (entry-level)
• Trex Select®: $20–$30 per sq ft (mid-range)
• Trex Transcend®: $25–$38 per sq ft (premium option)

This includes decking boards, fasteners, framing, and professional installation. DIY installation can reduce labor costs significantly.

Trex Decking Cost Formula

Here’s a simple way to estimate your total cost:

$$\text{Total Cost} = \text{Deck Area (sq ft)} \times \text{Cost per Square Foot}$$

Example:
If you’re building a 300 sq ft deck using Trex Select® at $26/sq ft:
300 × 26 = $7,800

This estimate includes materials and professional labor. Adjust your per-square-foot cost based on DIY plans or chosen Trex tier.
