Trex decking is a popular choice for homeowners looking to enhance their outdoor living space with a low-maintenance, durable deck. Installing Trex decking costs between $1,550 and $20,800, with most spending around $6,000. Whether you're dreaming of hosting backyard barbecues or creating a relaxing retreat, understanding the factors that influence Trex decking costs can help you plan your project with confidence.

Trex Decking Prices by Type

Trex decking prices range from $5 to $12 per square foot, depending on the series. Each product features a 25-year limited warranty to help protect against material defects or fading. Your choice depends mostly on your budget and the color selection.

Trex Transcend

Trex Transcend® pricing runs from $10 to $12 per square foot. This series features the largest selection of colors and the best long-term performance with 0.94-inch thick solid boards. If you’re looking for an affordable and environmentally-friendly alternative to exotic hardwoods, this may be a good choice, as it's long-lasting and durable.

Trex Select 

Trex Select® pricing ranges from $7 to $9 per square foot. This series offers more color choices than Enhance Basics but is less expensive than Transcend.

Select features slightly thinner boards at 0.82 inches. This design makes a seamless installation quicker and easier, but you can’t mix and match with Enhance or Transcend.

Trex Enhance 

Trex Enhance® costs between $5 and $7 per square foot, offering an affordable option without sacrificing quality. Both styles—Naturals and Basics—feature a 0.94-inch thickness with a scalloped bottom to reduce weight and cost. 

The Naturals style provides a more natural wood grain finish with additional color choices, perfect for those seeking a balance between beauty and budget. The Basics style delivers a clean, classic look at the most budget-friendly price, starting as low as $5 per square foot.

Trex Decking Cost per Square Foot

Building a deck costs $10 to $27 per square foot for Trex materials and installation of a basic substructure. Keep in mind that additions like stairs and railings can increase the cost up to $62 per square foot. Here's what you might expect to pay based on common deck sizes:

• 100 square feet: $1,000–$2,700

• 144 square feet: $1,440–$3,900

• 300 square feet: $3,000–$8,100

• 400 square feet: $4,000–$10,800

• 600 square feet: $6,000–$16,200

Choosing the right deck size depends on how you plan to use your outdoor space. A smaller deck is perfect for intimate gatherings or a cozy seating area, while a larger deck is ideal for hosting family events and entertaining friends.

Labor

Labor for Trex decking installation costs about $8 to $22 per square foot. A professional deck builder can replace an old deck with Trex boards in one to three days, and costs fall on the lower end of the range. 

More complex projects, including those requiring framing, railings, and stairs, will take around a week and cost more for labor at $15 to $35 per square foot.

Trex Accessories and Add-On Costs

To customize your Trex deck to your needs and wants, there are some accessories and add-ons that you might want to budget for. 

Trex Outdoor Lighting 

Trex Outdoor Lighting costs between $15 and $110 and lets you enjoy your deck when the sun goes down. Options include solar LED lanterns, string lights, statement lamps, and more. 

Trex Lattice 

Trex Lattice is priced between $195 and $960 each. Your cost depends on the size of your deck and the lattice style you choose. 

Trex RainEscape Cost

Trex RainEscape costs $2.50 to $4 per square foot, including materials and installation. This is a drainage system that you install below the deck boards to keep the area underneath clean and dry.

Although Trex is a composite wood product, most deck substructures are made of wood. RainEscape protects the substructure, so it’s less likely to rot, increasing the lifespan and durability of your new deck.

Trex Pergola Cost

A Trex Pergola™ starts at $8,840 and goes up from there. For a Trex Pergola with the ShadeTree Canopy, prices start at $8,600. 

Railing 

Trex railings cost $10 to $20 per square foot of deck space or $20 to $60 per linear foot, depending on the linear feet surrounding the deck perimeter and the number of posts. You can choose from multiple colors to complement your deck. Adding a railing increases safety, particularly for multi-level and multi-story decks. Plus, a railing creates a visual divide between the deck and the rest of the yard.

Other Trex Decking Cost Factors

Beyond deck size and your choice of Trex product, several other factors can influence the total cost of your project. Understanding these can help you plan your budget more effectively.

Permits

A building permit for installing a deck can run anywhere from $200 to $1,000. That cost will increase if you plan to run gas or electric lines to the deck. Check with a composite deck company near you that should be familiar with permitting regulations in your area.

However, it's not always necessary to obtain a permit for a single-level deck, but you'd need to check the local regulations. A multi-level or multi-story deck is much more likely to require a permit.

Stairs

Installing Trex decking stairs costs between $20 and $50 per square foot. The complexity of the project, the number of stairs, and the height will affect the actual cost. 

Fencing

Trex fencing costs $55 to $160 per linear foot, including posts, fence panels, and labor. If you want to install expensive features like a double-open gate, plan to pay on the higher end.

Trex vs. Wood Cost

While Trex decking costs between $5 and $12 per square foot—slightly more than the $3 to $7 per square foot for traditional wood planks—it offers significant long-term savings and benefits. Comparing wood to composite decking like Trex, you’ll notice that Trex decking is low-maintenance, which saves around $400 per year on upkeep that wood decks require (like cleaning, painting, and staining). Plus, Trex is made from recycled materials, making it an eco-friendly choice. It resists rot and mildew and won't warp, so you can enjoy a beautiful, durable deck without the ongoing deck repair costs associated with wood.

DIY vs. Hiring a Trex Installer

Trex boards are designed for ease of installation, and you can save 65% of the cost if you DIY. However, you’ll need the right tools and equipment, such as a drill, circular saw, and wheelbarrow, and you’ll need to ensure that the substructure is installed correctly for safety and longevity. Hiring a professional can give you peace of mind that the job is done right and your deck is safe to use for years to come.

By partnering with a skilled installer, you can enjoy your new Trex deck without the stress of DIY challenges. If you're ready to transform your outdoor space with a beautiful Trex deck, contact a local deck builder who can bring your vision to life.
