Introduction to Trex Decking
Trex is a well-known composite decking brand. Its decking materials are made from 95% recycled materials. The main ingredients include recycled wood fibers and recyclable plastics. This makes it more durable and environmentally friendly than traditional wood.
Trex decking is also resistant to fading, staining, and mold. Additionally, it won’t rot, warp, or attract pests like wood. Many families use it as a long-term investment for their outdoor space. Of course, there are many other equally high-quality composite deck brands on the market, such as EVODEK and TimberTech.
How Much Does Trex Decking Material Cost?
In general, the initial investment for composite decking is higher than for wood decking. However, composite decking tends to be more economical in terms of long-term cost of ownership. Trex offers three major product lines. They each cater to customers with different budgets and aesthetic needs.
Trex Enhance Series
As an entry-level option, the Enhance Series is the most affordable. The cost of materials is approximately $5-$7 per square foot. While economically priced, it still offers reliable performance. It is a good choice if you want a cost-effective deck that looks close to natural wood.
Trex Select Series
The Trex Select Series is Trex’s mid-range line. It is priced at around $7-$9 per square foot. This line offers a variety of classic color options. It has a lighter texture and a clean look. Therefore, they are widely used in a variety of scenarios.
Trex Transcend Series
Trex Transcend is a high-end composite deck. It represents the highest quality of Trex. Therefore, it will be more expensive than the other two. The material cost is about $10-12 per square foot. The Transcend series not only offers the best scratch resistance but also a wider selection of colors and styles. It has a deeper, more natural texture. In short, it is ideal for high-end deck designs.
Installation Cost
The total installation cost of composite decking boards consists of two parts: material cost and labor cost. The labor cost for professional installation usually ranges from $5-$15 per square foot. It depends on the following factors:
Infrastructure
If the composite deck needs to be installed directly over existing deck framing, labor costs will be lower. However, if your deck requires new framing, then the total cost will increase. In addition, accessories such as fencing and handrails will also change the total cost.

Design Complexity
In general, simple rectangular decks cost the least to install. While designs with curved edges or complex angles require more labor hours and skills. As a result, the cost of labor increases accordingly. In addition, some homeowners add other features to their decks, such as storage, to their designs. These will increase the difficulty and workload of installation, and the price will be higher accordingly.
Regional Differences
Labor costs also vary significantly from region to region. Therefore, the total cost of building a composite deck also depends on the wage level of local workers. Therefore, before you start your decking project, consult the builder about the cost of the work. In addition, know your local codes before you build. Find out if your building requires a construction permit.
Installation Methods
Certain experienced homeowners opt for DIY installation. DIY installation will indeed save a lot of money on installation. However, it is important to note that you should carefully read the installation guide provided by Trex. On the other hand, a professional installer is slightly more expensive, but can avoid costly mistakes.
In addition, it is recommended that you use hidden fasteners in order to make your deck more attractive and durable. Although it will increase the price per square foot by $1 to $2.

Cost Estimates for Different Deck Sizes
Based on common deck sizes, we can calculate the total cost of a Trex deck project. Below is a range of estimated costs for a new Trex deck:
- Small Deck (10’x10′, 100 square feet): $2,100 to $3,800 for materials and $4,500 to $7,500 for assembly.
- Medium Deck (12’x16′, 192 square feet): $3,100 to $5,700 for materials, $8,650 to $13,450 for assembly.
- Large deck (16’x20′, 320 square feet): $5,000 to $8,000 for materials; $12,000 to $18,000 for installation.
These are the total costs involved in building Trex decks of various sizes. Of course, actual costs may vary depending on the specific location and design.
Key Factors Affecting Trex Costs
Many factors can affect the final cost of a composite deck. Understanding these will help optimize your budget and design options.
Deck Size and Design Complexity
Of course, the larger the area, the higher the cost of materials and labor. The more complex the design, the higher the total cost will be. Therefore, consider carefully what kind of deck you need. Avoid over-designing and over-construction.

Additional Features
Composite decking alone is relatively inexpensive. However, there are decks that include additional features in their overall design. These will cost more. Example:
- Railing Systems: Trex railing costs about $20-60 per foot, and a medium-sized deck may require a $1,000 railing budget.
- Stairs: Steps cost about $100-$250 per step, depending on materials and design.
- Lighting Systems: Outdoor lighting is about $15-$100 per fixture, with the total cost related to the number of fixtures you use and the design.
- Composite Gazebos: Trex gazebos are also relatively high-cost add-ons. Of course, you can also look for other manufacturers to purchase less expensive composite gazebos.
Frame Materials
Traditional pressure-treated wood frames are the most economical choice. While brands such as Trex, EVODEK, and TimberTech offer more durable composite materials. Although they cost more, their longer lifespan makes them more cost-effective as well.
Site Conditions and Seasonal Factors
Sloping, hard-to-access backyards can make construction more difficult and costly. If you need to remove the old deck, this will also require an additional cost. In addition, you can choose to build in the fall and winter if you are able to do so. Off-season construction can result in more discounts from contractors.

Cost-Saving Tips
If you have a limited budget, the following methods can help you reduce the total cost of your composite decking project:
- Choose a More Cost-effective Brand: There are many quality composite decking brands on the market. Brands such as EVODEK and TimberTech also offer good performance and warranties. You can consult multiple quotes to find the best option.
- Simplify The Design: Choose a standard rectangular layout. Avoid complex curves and multi-level designs. This can significantly reduce material and labor costs.
- DIY Part of the Job: Experienced DIYers can take care of the preparation work, such as removing the old deck and transporting the materials themselves.
- Off-Season Purchasing and Installation: Contractors typically offer discounts of 5%-10% during the fall and winter months. Material suppliers may also have promotions. You may choose to buy composite deck boards in bulk during the discount period. This can save a significant amount of money.
- Categorize the Construction: The construction can be done by completing the main deck first. Additional features such as railings and lighting can be added gradually at a later stage as needed.
Conclusion
Building a composite decking not only enhances the quality of life, it is also a wise investment in your property. While the initial cost of Trex decking is higher than traditional lumber. However, composite decking’s extremely low maintenance needs and 25+ year lifespan make it less expensive in the long run instead. By choosing the right brand and design options, you can effectively control your budget.
Whether you choose Trex decking or another brand. Composite decking can provide you with a quality outdoor living space. If you want to know more about the cost of composite decking, please contact us. EVODEK can provide professional design solutions.
