This guide will help homeowners calculate Trex decking costs and understand the benefits this unique composite offers.

What is Trex composite decking?

There are many types of decking materials on the market, but composite options have become a favorite among homeowners and contractors. Trex is a popular brand of composite decking made from a combination of recycled wood fibers, plastic, and binding agents. Founded in 1996, Trex is the world’s largest manufacturer of wood-alternative decking products.

Composite decking is designed to be more resistant to the elements than traditional wood and is less susceptible to pests and mold. It’s also easier to take care of, since it doesn’t require sanding, staining, or sealing. While composite decking can be more expensive up front, it’s often more cost-effective in the long run.

Trex deck boards are best for homeowners who want the look and feel of real wood without the maintenance that comes along with traditional decking lumber. Trex composite decking is offered in a wide variety of colors and designs, making it a top composite choice for homeowners and contractors.

Factors in Calculating Trex Decking Cost

When it comes to outdoor decking, Trex is a popular choice for many homeowners, but just how much does it cost? Pricing for Trex decking ranges from $1,600 to $9,600, with several factors helping to determine the final cost, including the following.

Square Footage

The square footage of a Trex deck is one of the primary factors that impact its cost. Larger decks usually cost more to build than smaller decks, since they require more materials and labor.

When calculating the cost of a Trex deck, contractors typically charge by the square foot. Trex decking cost per square foot varies between $5 and $12 for materials, depending on type and color, and costs an additional $5 to $15 per square foot for installation.

The complexity of the design can also influence how much a contractor charges per square foot. Decks with railings, stairs, and other features can cost between $20 and $62 per square foot for materials and installation.

Deck Material

Trex offers different decking series, including Enhance, Select, and Transcend, each with unique features and price points.

The cheapest option is Trex Enhance, which costs $5 to $7 per square foot and comes in Naturals and Basics styles. The Naturals line offers more Trex decking colors and a natural wood-grain finish, while Basics has a limited selection and a more synthetic appearance.

Homeowners looking for a mid-range option may like Trex Select. It’s pricier than Enhance and more affordable than Transcend, but it has a thinner profile. The Trex Select series costs between $7 and $9 per square foot.

Finally, the Transcend series is a good choice for those who want an affordable and environmentally friendly alternative to exotic hardwoods. It’s durable and long-lasting, though it has a price tag to match—between $10 and $12 per square foot.

Deck Color

Trex offers a wide variety of colors for its decking products. Trex Transcend features the largest selection of colors, but every series offers a range of color options to suit different tastes and styles. The color a homeowner chooses for the deck can impact the cost, as some colors may cost more than others.

Generally, Trex colors that feature complex and multicolor finishes tend to cost more than solid color options. For example, the Trex Transcend product line offers several premium tropical colors that cost more than the traditional solid colors in the same line. Solid colors in the Enhance series are the most affordable, costing as little as $5 per square foot.

Project Complexity

The complexity of a project can have a significant impact on the cost of building a deck, including Trex decks. For example, a deck with multiple levels, intricate designs, and custom features such as built-in benches, lighting, or railing systems will typically cost more than a simple deck with basic features. Complex projects require more time, labor, and specialized materials to complete, increasing the overall cost.

For example, Trex decking stairs cost between $20 and $50 per square foot, while railing costs between $20 and $60 per linear foot. Lighting costs between $11 and $104, while pergolas can add almost $9,000 to a Trex deck budget. Essentially, any design element beyond a simple rectangular shape is likely to add to the overall construction cost of a Trex deck.

Labor

The cost of labor for a Trex deck installation will vary depending on the size of a project, its difficulty level, and the amount of experience the installers have. The amount of time it takes to complete an installation also matters, as more hours add up to higher costs. While a more complicated installation might take several weeks, a simple deck installation might take only a few days. The labor cost may also vary depending on the geographical location of a decking project and the availability of qualified installers in that area. Labor costs for simple deck designs fall between $5 and $15 per square foot. For more complex designs, labor costs jump up to between $15 and $35 per square foot.

Permits

A construction permit is a legal document issued by a government authority that grants permission to carry out a specific construction project, such as a Trex deck. The cost of a permit can vary depending on the location and scope of the project, though permits for Trex deck installations cost between $200 and $1,000. Permit pricing can increase if gas or electric lines are part of the deck’s blueprint.

Single-level decks don’t always require permits. Homeowners will want to check to see if their deck design requires a permit, as working without one can result in fines and work stoppages.

Seasonality

Seasonality can affect the cost of building a Trex deck due to factors such as supply and demand and weather conditions. During the spring and summer months, there can be a surge in decking projects; higher demand for building materials and labor can result in increased costs.

Additionally, poor weather conditions can complicate the deck-building process, particularly in areas with harsh winters or rainy seasons. Decks can take longer to build, or construction may be paused completely, leading to increased costs and longer project timelines.

Planning and scheduling a deck installation during the off-season may help reduce costs and avoid delays due to high demand and adverse weather conditions.

Additional Costs and Considerations

When it comes to estimating Trex decking costs, it’s important to consider potential additional factors that go beyond materials and basic installation. For example, removing an old deck or adding outdoor lighting can noticeably increase costs. Here are some additional considerations a budget-conscious homeowner will want to consider when installing a Trex deck.

Trex vs. Alternative Composite Brands

Trex isn’t the only supplier of composite decking boards, but the company has a reputation for quality, innovation, and customer service that makes it a trusted brand in the industry. Homeowners on a budget may consider alternative composite brands with lower pricing, but there’s more to consider than cost alone.

Trex materials are engineered for maximum durability, and the company is committed to producing eco-friendly, sustainable products. Trex also offers a wide range of colors, textures, and styles to give homeowners more control over the aesthetics of their deck. Additionally, Trex offers warranties ranging from 25 to 50 years, adding significant value by providing peace of mind and confidence in a Trex deck’s quality and performance.

While other brands offer composite boards at a lower price point, it’s important for a homeowner to evaluate a composite material’s quality, performance, durability, and warranty before making a final decision.

Old Deck Removal

Knowing when to repair or replace a damaged deck can be difficult. But removing an existing deck to install a composite upgrade will certainly influence the cost of installing a Trex deck. Demolition and removal of materials can be a significant additional cost, depending on the size and condition of the existing deck. The national average price of deck removal is around $850.

In some cases, a homeowner may be able to save on the cost of deck removal with a DIY approach. However, if the deck in question is large, in poor condition, or made of materials that require special handling (like pressure-treated lumber), it’s best for a homeowner to hire a professional for the removal.

Contractors often include the cost of old deck removal in their installation quote, but homeowners will want to confirm beforehand to avoid a costly surprise.

Framing

A deck frame is the underlying structure that supports a deck’s surface. All decks require proper framing for safety and stability. Framing also improves a deck’s longevity and durability. Deck frames are typically made from pressure-treated lumber or steel and consist of beams, joists, and posts anchored to the ground or a concrete foundation.

The cost of a deck frame depends on its size, the deck design it needs to support, and its materials. The height of a deck can also influence framing costs, with elevated decks costing more to frame than those closer to the ground. Homeowners can expect to pay anywhere from $15 to $35 per square foot on installation labor for a deck frame.

Rails and Stairs Installation

Both rails and stairs are important deck components that influence the safety and accessibility of the structure. In many areas, local building codes determine railing height and spacing, while stairs must rise and run consistently. In some areas, ground-level decks may not be required to have rails or stairs, so while these components aren’t a guaranteed additional cost, they’re worth keeping in mind when homeowners are budgeting a Trex deck.

Depending on the number of stairs and the complexity of the design, Trex decking stairs typically cost between $20 and $50 per square foot. Costs for railings along a stairway or surrounding a deck range from $20 to $60 per linear foot.

Outdoor Lighting Installation

There are several benefits to installing outdoor lighting on a Trex deck. To start, lighting can enhance the visual appeal of a deck and create a warm and inviting atmosphere. Strategically placing lighting around a deck can also help highlight architectural features while improving the safety of the space, and outdoor lighting can make it easier to extend the usability of the deck into the evening hours.

Homeowners have several options when it comes to installing outdoor lighting on a Trex deck, including post cap lights, recessed deck lights, and accent lights; other features include step lights, under-rail lights, rope lights, and solar lights. Adding outdoor lighting to a Trex deck costs between $15 and $110, depending on the chosen elements.

Trex RainEscape Installation

While a Trex deck is made from composite, its substructure is likely to be made of wood. A wooden frame is susceptible to mold, mildew, and rot, especially if moisture is an issue. A Trex RainEscape is a drainage system installed beneath the deck and designed to keep the space clean and dry.

Homeowners building Trex decks in drier climates may not feel the need for a RainEscape. But for those in areas with long rainy systems or harsh winters that can leave decks exposed to melting snow and ice, the added cost of a RainEscape can improve the longevity of the deck, saving money over time.

A Trex RainEscape costs between $2.50 and $4 per square foot, including materials and installation, making it an overall affordable decking component with substantial benefits.

Trex Pergola Installation

A pergola is often incorporated into a Trex deck to provide a shaded sitting area. Pergolas can offer aesthetic appeal along with several practical benefits. For example, they can help to define different outdoor living spaces while creating privacy. Since pergolas can be equipped with lighting, ceiling fans, and other features, they can also add functionality to a Trex deck, allowing homeowners to utilize the space in a variety of weather conditions.

Installing a Trex pergola can influence the total construction cost of a deck. Homeowners can expect to pay between $5,700 and $35,000 for a Trex pergola, with the final cost determined by the structure’s size and materials. Trex offers pergola kits in a wide variety of sizes, shapes, colors, and designs.

Trex Lattice Installation

Lattice panels are a versatile and practical option for homeowners looking to add privacy and shade to their Trex deck. Lattice panels typically consist of a crisscrossed design and can add visual interest to a deck while providing protection from the elements. Lattice panels can also be used as a trellis for climbing plants, like roses, to create a natural and organic privacy screen.

A Trex lattice costs between $195 and $960 per panel, depending on the size and design. Lattice doesn’t need to line the entire perimeter of a Trex deck. To stay on budget, homeowners can add lattice to the areas where it’s most needed, like on a pergola or floating deck. However, if a homeowner is considering using a lattice underneath the deck to create a skirting, it’s typically recommended to line the entire perimeter.

Types of Trex Decking

Homeowners can choose from several types of Trex decking. Each series is unique in color options, durability, thickness, longevity, and pricing. Three common types of Trex decking are outlined below.

Trex Enhance

Trex Enhance is the most budget-friendly option. Deck boards cost between $5 and $7 per square foot and measure 0.94 inches thick. They feature a scalloped bottom that improves drainage and ventilation to prevent moisture-related issues like mold and rot.

Compared to other budget-friendly Trex options, Enhance is incredibly resistant to scratches. The series offers two styles, Naturals and Basics. The Naturals style features a more authentic wood-grain pattern for a rustic look, while the Basics style is more uniform in appearance, making it a better fit for modern and contemporary decks.

It’s worth noting that Enhance may not have the same level of durability as other Trex series, and color options may be limited.

Trex Select

Trex Select has a thinner profile than Enhance, measuring 0.82 inches thick. While it does have a lower resistance against scratching compared to other Trex varieties, it’s easier and faster to install. This advantage can make it more affordable, despite its higher price point of $7 to $9 per square foot. If a homeowner is considering a DIY installation, Trex Select is the easiest series to work with.

Compared to Enhance, Select is more resistant to fading and staining. When it comes to style options, the Select series has a solid profile design that provides a more traditional look. The series also offers additional color choices compared to those in the Enhance line of products but has limited texture options compared to those in the Transcend line.

Trex Transcend

Trex Transcend is the most expensive option in the group but offers the best quality. Boards cost between $10 and $12 per square foot and measure 0.94 inches thick. Transcend features superior resistance to fading, staining, and scratching, ensuring that a deck made of the material will retain its appearance for years to come.

Transcend is heavier, and its denser profile may require more labor to install. While Transcend costs more than other Trex decking series, its longevity and low maintenance make it a popular choice for homeowners who want to enjoy the benefits of Trex composite decking for as long as possible.

Benefits of Trex Decking

For homeowners looking for a durable, sustainable, and easy-to-maintain decking material, Trex decking may be the perfect solution. Here are a few reasons for homeowners to keep in mind when comparing composite vs. wood decks.

Durability

A durable deck is made from strong materials able to withstand the test of time. Trex decking material is designed to provide homeowners with a reliable and long-lasting outdoor living space that doesn’t present common issues associated with other types of decking materials.

For example, Trex deck boards are resistant to damage from insects, such as termites, and are less likely to fade or stain. Trex decks are also less likely to rot, warp, or splinter over time, making them less likely to break or fail.

Durable decks are safer and maintain their appearance for longer, which can increase a home’s resale value. Overall, Trex decking offers longevity that other decking materials just can’t offer without the cost of deck repairs and strenuous upkeep.

Sustainability

Trex decks are incredibly sustainable. Trex boards are made from 95 percent recycled materials, including reclaimed wood, sawdust, and grocery bags. For homeowners looking for home improvement materials that help reduce their carbon footprint, Trex decking offers sustainability and style.

Additionally, as already mentioned, Trex decking is quite durable. While other decks need to absorb additional materials for repairs and replacements, a Trex deck can stand strong without the need for additional resources.

Finally, Trex decks are low-maintenance and don’t require the regular application of sealers and stains that can contain harmful chemicals for both people and the environment. Overall, Trex decks are more sustainable and eco-friendly than other decking materials.

Customization Options

Trex decks can be designed to fit a homeowner’s style and preferences. Trex boards come in many different colors, textures, and patterns. The company also offers a variety of deck accessories, including railing systems, lighting, and pergolas.

Trex offers more than just aesthetic customizations. Homeowners can also choose from different Trex series that offer different levels of durability and maintenance at different price points to help homeowners customize their outdoor spaces without going over budget.

Finally, Trex boards are compatible with a range of deck framing options, including steel, wood, and aluminum, making a Trex deck customizable from top to bottom.

Easy Maintenance

Compared to other materials, Trex decks are generally easy to maintain. Trex boards are made from recycled materials that don’t require the same level of upkeep as wood. At the same time, Trex boards tend to outperform other decking materials despite their constant maintenance.

Unlike natural wood decks, Trex decks don’t require regular staining, sealing, or power washing to maintain their appearance or prevent decay. Homeowners with a Trex deck spend less time and money on upkeep than their neighbors with wood decks. A homeowner only needs to wash their Trex deck with some soap and water to remove dirt and debris as needed, giving them more time to enjoy their outdoor living space.

Trex Decking Installation: DIY vs. Hiring a Professional 

When it comes to choosing between a DIY installation or hiring a professional for a Trex deck, there are pros and cons to consider for both.

A DIY Trex deck can offer substantial cost savings. By doing the work themselves, homeowners can save around 65 percent off a professional quote. Homeowners will want to keep in mind that they may need to budget for added costs such as PPE, tools, and a wheelbarrow. This can increase the cost of a DIY project by $500 to $1,000.

However, without the proper experience, a homeowner can make costly or dangerous mistakes during a DIY install. A homeowner may also not be familiar with local building codes and regulations and could end up building a noncompliant deck. A DIY install can also void a Trex warranty if materials are improperly installed.

Hiring a professional to install Trex deck boards offers several benefits. To start, professionals have the necessary skills, knowledge, and experience to complete a Trex decking installation correctly and efficiently. They’re also familiar with safety protocols and can usually complete a deck much faster than a homeowner, all while offering Trex deck ideas that boost the visual impact and functionality of the space.

Working with a professional does have its drawbacks. It can be difficult for a homeowner to coordinate their schedule with a contractor, and it will almost always cost more to have a professional install a Trex deck.

Unless a homeowner is a decking pro, they’re advised to hire a professional deck builder who has the expertise and experience to deliver a safe, durable, and aesthetically pleasing deck.

FAQs

Trex composite is a great option for homeowners looking for durable, low-maintenance decking material. The cost of Trex decking varies, and while it can cost more to install than more traditional decking materials, its longevity makes it a wise investment for any outdoor space. For curious homeowners, the following FAQ section offers additional insight into Trex decking.

Q. Does Trex decking warp?

Wood warping on a deck is usually caused by moisture and temperature changes. Wood swells as it absorbs moisture and shrinks as it dries out. This expansion and contraction can cause the wood to warp, twist, or bow. While Trex composite does absorb water, it’s very little compared to what wood absorbs, making it highly resistant to warping.

Q. Is Trex decking worth the cost?

Trex decking is considered a high-quality composite material that can add value to a home. While installing a Trex deck may cost more up-front than installing a deck made out of traditional lumber, composite is known for its durability and ease of maintenance. The benefits of Trex make it a worthwhile investment.

Q. Is Trex decking slippery when wet?

Yes, Trex decking can be slippery when wet. But the material is designed to be less slippery than other common decking materials. Concerned deck owners can also apply a slip-resistant coating or paint to their Trex boards to make the surface less slippery after a rainstorm or when it comes time to clean their deck with soap and water.

Q. Does Trex decking get hot in the sun?

Like many other materials, Trex decking can get hot in the sun. On hot days, it’s best to avoid walking on decking barefoot and practice safe practices with children and pets. It’s also recommended to install a lighter shade of Trex decking to minimize heat retention. Overhead awnings and pergolas can help as well.

Q. How much does a 20×20 Trex deck cost?

For materials and installation, a 20-foot by 20-foot Trex deck can cost anywhere from $4,000 to $10,800. The final price is determined by the Trex series and color or pattern. The design of the deck also influences the cost, as more detailed layouts, like seating or stairs, can increase the installation cost per square foot.

Q. What are the pros and cons of Trex decking?

Trex decking is low maintenance and easy to clean. It’s also highly durable and resistant to damage from extreme weather, pests, mold, and mildew. Trex decking is also a great choice for families, since it’s slip-resistant and splinter-free. However, Trex decking can be difficult to repair if it’s damaged, and it’s typically more expensive than other decking materials.
