When it comes to upgrading your outdoor living space, Trex decking is a popular choice for homeowners in Kirkland, Bellevue, Bothell, and the greater Seattle area. Known for its durability, low maintenance, and eco-friendly materials, Trex offers a long-lasting solution that enhances your home’s curb appeal and functionality. But one of the first questions I hear is: How much does Trex decking cost per square foot? Understanding the pricing helps you plan your budget and make informed decisions about your deck project.


In this post, I’ll walk you through the key factors that influence Trex decking costs, provide a detailed breakdown of pricing, and offer practical advice to help you get the best value for your investment.



Understanding Trex Decking Pricing


Trex decking pricing varies based on several factors, including the type of Trex product you choose, the size of your deck, and the complexity of the installation. Trex offers different product lines, each with its own price point and features:


  • Trex Select: The entry-level option, offering good durability and a natural wood look.

  • Trex Enhance: Mid-range with more color options and a slightly higher resistance to fading and staining.

  • Trex Transcend: Premium decking with the highest durability, rich colors, and a more realistic wood grain texture.


In addition to the decking boards themselves, you’ll need to consider the cost of framing materials, fasteners, railings, and any additional features like lighting or built-in seating.


Labor costs in the Seattle area, including Kirkland, Bellevue, and Bothell, can also impact the overall price. Skilled installation ensures your deck is safe, level, and built to last, so it’s worth investing in experienced professionals.

What Influences the Cost of Trex Decking?


Several key factors influence the final cost of your Trex deck:


1. Deck Size and Shape

The larger your deck, the more materials and labor you’ll need. Complex shapes or multi-level decks require more precise cutting and installation, which can increase costs.


2. Decking Material Choice

As mentioned, Trex offers different product lines. For example, Trex Select might cost around $5 to $7 per square foot, while Trex Transcend can range from $10 to $12 per square foot or more.


3. Substructure and Framing

If your existing deck frame is in good condition, you might save money by reusing it. However, many decks require new framing, especially if you’re upgrading from wood to composite decking.


4. Railings and Accessories

Railings add safety and style but also add to the cost. Trex railings come in various styles and materials, from simple aluminum to composite options that match your decking.


5. Labor and Permits

Labor rates in the Seattle metro area typically range from $30 to $60 per hour depending on the contractor’s experience and the project complexity. Don’t forget to factor in permit fees required by local municipalities like Kirkland or Bellevue.



How much is a 500 sq ft Trex deck?


To give you a practical example, let’s break down the cost of a 500 square foot Trex deck in the Seattle area.


  • Decking Material: Choosing Trex Enhance at approximately $8 per square foot means $4,000 for decking boards.

  • Framing and Substructure: New framing might cost around $4 to $6 per square foot, adding $2,000 to $3,000.

  • Railings: A basic Trex railing system can cost $30 to $50 per linear foot. For a 500 sq ft deck, assume 60 linear feet of railing, totaling $1,800 to $3,000.

  • Labor: Installation labor might run $5 to $10 per square foot, so $2,500 to $5,000.

  • Permits and Miscellaneous: Budget around $300 to $600 for permits and small materials.


Estimated total cost: $10,600 to $15,600 for a 500 sq ft Trex deck.


This range reflects the quality and craftsmanship you can expect when working with trusted local contractors in the Seattle area. It’s important to get detailed quotes and understand what’s included to avoid surprises.

Tips for Getting the Best Value on Your Trex Deck


Building a Trex deck is a significant investment, so here are some tips to maximize your value:


  • Choose the Right Product Line: Match your budget with the right Trex product. If you want premium durability and aesthetics, Trex Transcend is worth the extra cost.

  • Plan Your Deck Size Wisely: Larger decks cost more, but sometimes a well-designed smaller deck can provide better functionality and enjoyment.

  • Consider DIY for Some Tasks: If you’re handy, you might save on labor by handling demolition or finishing touches yourself.

  • Get Multiple Quotes: Local contractors in Kirkland, Bellevue, and Bothell can vary in pricing and services. Compare estimates carefully.

  • Ask About Warranties: Trex decking comes with a warranty, but also inquire about workmanship guarantees from your contractor.

  • Think Long-Term: Trex decking’s low maintenance means you save money on staining, sealing, and repairs over time.



Why Trex Decking is a Smart Investment for Seattle Homeowners


Seattle’s climate—with its frequent rain and seasonal changes—demands decking materials that can withstand moisture, resist mold, and maintain their appearance year after year. Trex decking is engineered to meet these challenges, making it a smart choice for homeowners in Kirkland, Bellevue, Bothell, and surrounding communities.


  • Durability: Trex is made from recycled wood fibers and plastic, creating a composite that resists rot, splintering, and insect damage.

  • Low Maintenance: Unlike traditional wood decks, Trex requires no sanding, staining, or sealing.

  • Eco-Friendly: Using recycled materials helps reduce environmental impact.

  • Aesthetic Appeal: Trex offers a variety of colors and finishes that mimic natural wood without the upkeep.


Investing in Trex decking means you’re choosing a product that enhances your home’s value and provides a beautiful outdoor space for years to come.

If you’re ready to explore Trex decking for your home, start by assessing your outdoor space and envisioning how you want to use your deck. Consider factors like:


  • Sun exposure and shade

Next, reach out to local contractors who specialize in deck installation. They can provide expert advice tailored to the Seattle climate and local building codes. Remember, a well-built deck is not just about materials but also about quality workmanship.
