Composite deck with landscaping
3 June 2024,

If you are considering building a composite deck, you have come to the right place.

A composite deck instead of a wooden deck is a wonderful idea that can save you a ton of money. 

One of the popular brands of composite decks is Trex, and materials include not only the deck but the stairs, hardware, railing, fasteners, and the deck.

Trex composite decks can be DIY projects if they are small and simple. For more complex designs with many stairs, a deck professional would be the best person for the job!

What is a Trex Deck?

A Trex deck is made of composite materials as another alternative to traditional wood.  In fact, a composite deck can outperform a wooden deck because it doesn’t splinter, warp, or rot.

Made of reclaimed wood, it is a “green” option that is easier to maintain and clean.  It will last much longer than a wooden deck, that’s for sure.

A Trex deck comes with a warranty ranging from 25 to 50 years and is easy to install with a patented fastening system.  You can also choose from a variety of colours and finishes that give the appearance of natural wood.

What is the average cost of a Trex Deck Installation?

The pricing for a Trex deck installation depends on factors like the size of the deck and your contractor. But on average, you can expect to pay around $8,000++ for materials and labor for a standard size deck.  It costs around $20 to $30 per square foot.

Homeowners who like DIY projects can spend around $2,000 on materials for a small deck with a simple design.

The square footage of your deck will account for a huge chunk of the cost.  The bigger the deck, the more expensive it will be for materials and labour.

Below is a table with common deck dimensions and the cost of Trex materials.  A deck professional will charge an average of $8 to $22 per square foot for labour so you need to factor labour costs into your budget as well.

Trex materials are advertised to cost $30 or less per square foot according to the company’s website.  But let’s break down the prices a little more.

According to the Size

As mentioned earlier, the cost of a deck is greatly influenced by its size.  The deck itself could cost around $12 or less but other materials like stairs and rails can increase the project cost per square foot.

Keep in mind that deck professionals will also charge labor costs based on the square footage.

According to Line

Trex products have different quality ratings from good to best for its decks and rails. 

Good Quality: Trex Enhance for decking and Trex Select for Railing is durable, affordable, and available in 3 colours.

Better Quality: Trex Select Earth Tones and Trex Enhance Naturals are medium-quality decking options while Trex Enhance is for railing.  This line of decking comes in 5 colours and are resistant to mildew and mold.

Excellent Quality: Trex Transcend is the company’s excellent decking line while Trex Signature is its best railing system.  Both are very durable systems and have protection against fading.

Refer to the table below to compare the price differences among Trex decking systems based on quality.  Again, take note that these do not include hardware and fasteners, stairs, and railings.

$5 – $8

Select Earth Tones / Enhance Natural

$7 – $10

According to Design

Unique shapes, complex designs, many stairs, and type of railing can increase the cost of a deck installation significantly.  Labor costs also increase when the contractor has more heights and shapes to follow.

According to the frame 

The substructure or frame below the deck is also included in the cost estimates for a Trex deck.  If you already have an existing deck with a stable foundation and simply want to replace the deck, you can omit this cost.

Price of a Trex Deck vs. a Wooden Deck

As mentioned earlier, a Trex deck can cost $12 or less per square foot but the cost can increase to $30 per square foot with the stairs, railing, etc.

It could be more expensive than a wooden deck made with pressure-treated lumber of redwood (usually costs around $8 per square foot).  Keep in mind, however, that a Trex deck will last much longer than a wooden deck and will cost much less in maintenance and repairs over time.

The average cost of a cedar wood deck is about $8,000 while a Trex deck of the same size may cost around $12,000.

Adding extra features to your Trex Deck

The addition of extra features will make your Trex deck stand out but they will also drive up the cost.  These extra features include:

  • Outdoor lighting
  • Deck furniture
  • Fence
  • Pergola
  • Rain Escape (Trex under-deck drainage system)
  • Cornhole sets
  • Outdoor kitchen

While you don’t need to get these items from Trex, some of these features may be necessary such as deck lighting, furniture, and drainage system.

You will need a bigger budget if you wish to install extra features.  A deck fence could cost from $2,000++ while a pergola could cost from $2,500 to $6,000.  An outdoor kitchen can cost as much as $50,000 to $100,000, depending on the design and materials.

What are the advantages of installing a Trex Deck?

Trex decks guarantee durability, easy maintenance, and environment-friendly construction. These benefits make a Trex deck an outstanding choice.

Exceptional durability: With recycled plastic and wood fibers, a Trex compositedeck has a longer lifespan and needs fewer repairs.

Easy to maintain: Unlike wooden decks, a Trex composite deck does not require staining, painting, or sealing which means savings for you.  It is also made to resist mold, staining, and fading.  It only needs to be cleaned with soap and water.

Environment Friendly: On top of its aesthetic appeal, a Trex composite deck uses plastic materials and recycled wood, making it a sustainable choice.

What is the best time for a Trex Deck Installation?

Depending on your location, some deck contractors may not operate during winter due to extreme weather conditions that make a deck installation impossible to do.

Preparing to install a deck

This means that most homeowners plan to build a deck in summer and spring to take advantage of the good weather. This also means that contractors charge peak rates at these times because of high demand.

It is also possible to install a deck in the fall. Deck contractors are less likely to be busy around this time and may charge much lower rates.

Do you need a permit to build a deck?

Building codes vary depending on your location. In most instances, a permit is required to install a deck.  A permit could cost up to $300 based on your municipality’s regulations.

A deck contractor can assist you in obtaining the proper permits for your project.

How long is the installation of a Trex deck?

A professional can install a Trex deck in 5 to 7 days but this will vary depending on the size and design of the deck. Of course, the experience and skills of your selected contractor will have an impact on the quality and speed of your project.

A composite deck is lighter than other types of materials so it takes much less time to build.

How much is the labor cost for a Trex deck installation?

Are you building a 500-sq. ft. composite deck? A Trex deck of this size can cost from $8,000 to $12,000 in materials alone. For the labor cost of a professional installer, you should prepare a budget of $5,000 to $11,000.
