Composite decking has become a popular alternative to traditional wood decking due to its long-term cost savings. One of the most well-known brands in the market is Trex, offering a range of decking products that are both durable and eco-friendly. Many composite decking providers like National Decking from Ontario, carry this product.
The cost of Trex decking materials ranges from $15 to $30 per square foot, including the substructure, railing, stairs, hardware, and fasteners. While smaller, simpler decks can be DIY projects, more complex designs may require the assistance of a professional deck builder, with labor prices ranging from $8 to $22 per square foot. Overall, the cost of a Trex deck can vary depending on its size and complexity.
Average Trex Decking Cost
The cost of a Trex deck varies depending on the size of the deck and who is doing the labor. On average, a homeowner can expect to spend approximately $7,500 for a complete Trex deck, which includes materials and labor. For those who prefer to do it themselves, a small 100-square-foot deck with basic Trex materials and design can cost as little as $1,500. However, for a larger 400-square-foot deck with a complex design, installed by professionals, the cost can reach up to $20,800. It is important to keep in mind that these prices are just averages and can vary depending on the specific project.
What Is Trex Decking?
Trex decking is a composite deck material that serves as a durable and eco-friendly alternative to wood. It is designed to outperform wood by being resistant to rotting, splintering, and warping. Trex decking is also stain-resistant and easy to clean. Made of 95% reclaimed wood, it is considered a green solution. Trex decking comes with a warranty of either 25, 35, or 50 years, which is not surprising given its long lifespan compared to actual wood. Installation is made easy with the patented Trex Hideaway Hidden Fastening System. It comes in a variety of colors that mimic real wood finishes, making it an attractive option for homeowners.
Trex Decking Cost by Square Foot
When it comes to Trex decking, one of the most significant cost factors is the size of the deck. As a general rule, the larger the deck, the more you’ll spend on both materials and labor. The table below outlines the costs associated with Trex decking based on common deck dimensions.
| Deck Size | Trex Material Cost (per square foot) |
| 144 sq ft | $6.00 – $7.50 |

| 576 sq ft | $6.00 – $7.50 |

It’s important to note that the prices listed in the table above do not include labor costs. If you plan on doing the work yourself, the displayed price is close to what you can expect to pay. However, if you’re hiring a professional, budget between $8 and $22 per square foot for labor in addition to the material costs.
Trex Decking Cost Breakdown
By Size
The cost of a Trex deck depends greatly on its size. The average cost per square foot ranges from $15 to $30. The decking itself costs between $5 and $12 per square foot, but additional components such as rails, stairs, hardware, and fasteners can increase the average price per square foot. Labor costs are also measured per square foot, making the cost of a large Trex deck add up quickly.
By Line
Trex offers a good/better/best system for its decking and railing products. The naming conventions for these products are not consistent, which can be confusing. The good decking option is called Trex Enhance, while the good railing option is called Trex Select. Trex Enhance decking is durable and affordable, and comes in three colors. The better decking options include Trex Select Earth Tones and Trex Enhance Naturals, while the better railing option is called Trex Enhance. Trex Select and Enhance Natural decking both come in five colors and are enhanced to prevent staining and resist mold and mildew. The best decking option is called Trex Transcend, and the best railing option is called Trex Signature. Trex Transcend decking has a wide range of colors and finishes, making it the most durable option and better protected against fading over time. The table below shows the cost difference between the three levels of Trex decking product lines. Additional costs such as railings, stairs, hardware, and fasteners are not included in these costs.
| Product Line | Cost Per Square Foot |
| Trex Enhance | $5 – $6 |
| Trex Select | $7 – $8 |
| Trex Transcend | $9 – $12 |
By Design
Deck designs that are more complex, such as those with unique shapes and many stairs and railings, can quickly increase the cost of a project. These materials are more expensive, and labor costs can go up significantly when the deck builder has to account for different shapes and heights.
Framing
The framing, or substructure, underneath the deck is included in Trex’s cost estimates. When using the Trex cost calculator, you have the option to omit this cost if you have an existing deck with a solid foundation and are only replacing the deck itself.
Trex Decking Labor Costs
Labor costs for installing a Trex deck can vary depending on the complexity of the project and whether or not you choose to hire a professional. If you have the necessary skills and tools, building the deck yourself with the help of some friends can save you money on labor costs.
However, if you prefer to hire a professional, Trex can assist you in finding a deck builder near you who specializes in Trex decks. Labor costs for building a Trex deck can range from $8 to $22 per square foot. For simpler projects without many stairs, railings, or intricate design details, labor costs can be expected to fall between $10 and $15 per square foot.
It is important to note that labor costs are only one aspect of the total cost of building a Trex deck. Materials, permits, and other expenses should also be factored into the overall cost.
Factors That Affect Trex Decking Costs
When planning to install a Trex deck, there are several factors that can affect the overall cost. These include adding extra features, the time of year, permits, and location.
Adding Extra Features
Trex offers a range of extra features that can be added to a deck, such as outdoor lighting, furniture, fencing, pergolas, and even outdoor kitchens. However, adding these features can increase the overall cost of the project. For instance, the cost of installing a fence can range from $1,600 to $7,000, while building a pergola can cost between $2,300 and $6,000. The cost of an outdoor kitchen can go as high as $100,000 for the ultra-luxury options. It’s important to consider which features are necessary and which ones can be added later to avoid unnecessary expenses.
Time of Year
The time of year can also impact the cost of installing a Trex deck. During the winter months, many deck contractors shut down, leading to a high demand in early spring and summer when people want to enjoy their outdoor spaces. This high demand can result in a spike in labor costs. On the other hand, late summer and fall are less busy periods for deck contractors, which may lead to lower labor rates.
Permits
Most municipalities require a permit to build a deck, which can cost between $100 and $300. It’s important to factor in this cost when planning the budget for a Trex deck project.
Location
The location of the project can also impact the cost of installing a Trex deck. Labor costs are generally higher in urban and coastal areas with a higher cost of living compared to suburban and rural areas. It’s important to consider the location when planning the budget for a Trex deck project.
In summary, adding extra features, the time of year, permits, and location are all factors that can affect the overall cost of installing a Trex deck. It’s important to consider these factors when planning the budget for a Trex deck project to ensure that the project is completed within budget.
Advantages of Trex Decking
Durable
Trex decking is a highly durable material that can withstand harsh weather conditions and resist rot, decay, and insect damage. Made from a unique blend of wood fibers and recycled plastic, Trex decking does not splinter, warp, or crack over time. This means that it has a longer lifespan compared to traditional wood decking, resulting in fewer necessary repairs and maintenance.
Low Maintenance
Trex decking requires minimal maintenance, making it an attractive choice for homeowners who want to save time and money on upkeep. Unlike traditional wood decks, Trex decking does not require staining, sealing, or painting. Additionally, it is specifically engineered to resist fading, staining, and mold growth, making cleaning easy with just soap and water.
Eco-Friendly
Trex decking is an eco-friendly option that utilizes recycled wood and plastic materials. By repurposing materials that would have otherwise ended up in landfills, Trex decking helps reduce waste and promote sustainability. This composite material not only creates a visually appealing deck but also highlights the importance of using recycled materials in construction.
Overall, Trex decking offers a compelling combination of durability, low maintenance, and eco-friendliness, making it a popular choice for homeowners looking for a long-lasting and sustainable deck option.
Ways to Save Money on Trex Decking
If you’re planning to build a deck using Trex decking, there are ways to reduce the overall cost of your project. Here are a few tips to help you save money:
Building the Deck Yourself
One of the easiest ways to save money on the cost of your Trex deck is to build it yourself. Labor can account for more than 50% of your Trex deck in some instances. Building a deck yourself is totally manageable if you’re willing to do the hard work. By doing it yourself, you can save thousands of dollars in labor costs.
Choosing the Right Time of Year
Choosing the right time of year to build your deck can also save you money. If you try to contract a professional to build your deck in the spring or summer, you’ll likely pay more than if you did it during autumn. Plus, the contractor might have a long waiting list due to high demand in the early season, meaning you may have to wait a month or more for the work to be done anyway.
Getting Multiple Quotes
Getting multiple quotes from different contractors can help you find the best deal. Ask friends, family, and neighbors for recommendations for deck builders, and check out their reviews online. After finding at least three that you like, get quotes for the project, then choose the contractor who can best meet your needs while staying within your budget.
Keep It Small and Simple
The larger the deck and the more complex the design, the more you’ll spend on materials and labor. Go with a straightforward deck design, and keep it small to save on costs. By keeping the design simple, you can also save money on materials and labor costs.
In conclusion, building a deck using Trex decking doesn’t have to break the bank. By following these tips, you can save money on your project while still achieving the beautiful, durable deck you’ve always wanted.
DIY Trex Decking Installation vs. Hiring a Professional
Building a deck is a challenging task that requires a certain level of skill, time, and effort. While a DIY Trex decking installation can save you money in labor costs, it can also lead to mistakes that could compromise the safety and longevity of your deck.
Hiring a professional deck installer can ensure that your deck is structurally sound and meets all safety standards. It can also save you time and effort, as professionals have the necessary tools and experience to get the job done efficiently. However, the cost of hiring a professional can nearly double the cost of your Trex decking installation.
To determine which option is best for you, consider your skill level, available time, and budget. If you have experience with DIY projects and are confident in your abilities, a DIY Trex decking installation may be a viable option. However, if you lack the necessary skills or simply don’t have the time, hiring a professional may be the best choice.
Overall, the decision to DIY or hire a professional for your Trex decking installation should be based on your individual circumstances and needs.

The installation time for a Trex deck depends on the size and complexity of the deck and the installer’s expertise. It can take between five and seven days to install a deck.

This could make a Trex deck installation go faster.

For materials alone, a 500-square-foot Trex deck will cost between $8,827 and $15,531, depending on the line of Trex decking you choose. This cost includes railing and substructure materials. If you’re paying a professional deck installer to do the work, you’ll need to add another $4,000 to $11,000 for labor.
