Trex has been around since 1996—when they created the composite deck materials category, which they have been perfecting ever since. The unique thing about Trex boards that sets them apart from any other deck material is that no trees have ever been cut down to manufacture a single board, because all Trex boards are made of 95% recycled materials, including recycled wood, sawdust, and plastic film.

Trex deck products are broken down into three categories of good, better, and best with the following corresponding product names - Trex Select, Trex Enhance, and Trex Transcend.
For the same 24’ x 12’ deck of 288 square feet, these are the specifics on the options available on the Trex website, using their pricing calculator for material costs:
|Trex Decking Features||Trex Select||Trex Enhance||Trex Transcend|
|Without railing and using an existing substructure||$1,924
|With Trex railing and using an existing substructure||$3,033
|Without railing and installing a wood substructure||$3,364
|With railing and installing a wood substructure||$4,473
|Without railing and installing a Trex substructure||$5,668
|With Trex railing and installing a Trex substructure||$6,777
A 24’ x 12’ (288 sqft) deck will take an average of 34.5 hours to build with a labor cost of around $2,165 for a deck to be installed on an existing substructure.
The labor to install a substructure, the deck, and the railings takes an average of 50 hours, which brings you to an installation cost of $3,138.
Of the three product lines, the Enhanced line is the only one available in the big box hardware stores like Home Depot and Lowes. The other product lines—Select and Transcend—are sold directly from the Trex website and are also available from big lumber providers like ABC Lumber.
Boards are .82 inches thick and come in lengths of 12 feet, with a width of 5.5 inches. They have the lowest grade of the Trex scratch resistance, and their grain pattern is the shallowest of the three products. There are currently five colors options available in two groups, including Madeira (brown), Saddle (brown), Woodland Brown, Winchester Grey, and Pebble Grey.
Boards are .94” thick, with a width of 5.5 inches, and come in lengths of 12’, 16’, and 20’. These have better scratch resistance than the Select boards and are carried in stock at Lowes and Home Depot. Compared to Select boards, they also have a deeper grain pattern, giving a more natural appearance, and they cost less than the top-of-the-line Transcend boards.
Currently, the Enhanced boards that you can order directly or at the hardware store are available in three colors in two groups, which include Beach Dune (brown), Saddle (brown), and Clam Shell (gray).
These are the top-of-the-line boards from Trex. Like the Enhanced line, Transcend boards are also .94 inches thick, with a width of 5.5 inches, and come in lengths of 12’, 16’, and 20’. In addition to having the best scratch resistance of the three, the Transcend line gives homeowners the most diverse style options. The color options are broken down into three styles.
This collection has five options and the tropical color options also have a two-tone appearance because of a black streak that runs through the finish. The strong color options available are Havana Gold (brown), Lava Rock (brown), Spiced Rum (brown), Tiki Torch (brown), and Island Mist (gray).
The colors in the Classic Earth Tones collection are more muted and edge toward pastel in appearance. The color options available are Firepit (brown), Rope Swing (brown), Tree House (brown), Gravel Path (gray), and Vintage Lantern (gray.)
Gravel Path (gray) and Spiced Rum (brown)
Your materials cost should not shift dramatically from the prices we have laid out here from the Trex pricing calculator, whether you order the Trex deck materials yourself or have your contractor order them.
Shipping costs will depend on which line of Trex boards you order. The Enhanced Trex boards are normally stocked by your local big box hardware stores, so the delivery costs would only need to cover the distance from that store to your door, and they may be covered by your contractor.
If, however, you want to go with materials from either the Select or the Transcend product line, you’ll need to find a large lumber supplier with them in stock that will order them in, or you will need to order them online and have them delivered.
Potentially, the less experience local contractors have with Trex, the higher the likelihood that the products aren’t carried locally.
Our labor estimate above is a generalized cost based on numbers from all over the country, but your location can change those numbers dramatically based on local labor costs.
In addition to the three categories of product lines in deck boards, Trex also manufactures aluminum handrails, aluminum gates, and more, which are marketed under the following brands:
Trex Elevations steel framing, Trex Select Railing, Trex Signature Railing, Trex Transcend Railing, Trex Faccia, Trex LatticeWorks, Trex Fencing, Trex Outdoor and Landscape Lighting, Trex Outdoor Furniture, Trex Outdoor Pergola, Trex Outdoor Kitchens, Trex Spiral Stairs Systems, Trex Fencing, and Trex RainEscape under deck drainage.
Of all the additional options, especially if you live somewhere with heavy rainfall, consider the addition of the unique RainEscape drainage system to keep water runoff away from the entire deck area.
Possible additional enhancements to your deck which are not covered in the pricing estimates include the following:
|Additional Options||Average Cost|
|Portable heaters||$100 – $500|
|Firepit basic||$200, or custom built $2,700 – $6,000|
|Outdoor fireplace||$1,500 – $6,500|
|Premanufactured seating||$350 – $1,100|
|Custom seating||$2,000 – $5,000|
|Planter boxes||$120 /each|
|Hot tub||$3,000 – $14,000|
|Outdoor shower||$800 – $1,000
($4,000 with privacy enclosure)
|Grilling area with sink||$1,500 and up|
|Cover||$1,000 manual, $1,700 motorized|
With the range of options available, you can really get creative on the deck space you can design for yourself and your family.
Obviously, if you decide to add any deviation from the standard rectangle shape and design, your costs will increase—drainage, outdoor lighting, kitchen space, benches, elevated platforms, etc.
Most people want their new decks built so they and their families can take advantage of their investment over the summer months. This means that many contractors will be more available, and potentially a bit more flexible on cost, if you have the deck installed in the late fall or winter.
Some people plan to add a second level but are planning to do half now and half later to spread out the cost. Keep in mind that for many contractors, it will end up being a cheaper overall project to get the entire project built at one time rather than have the same or different contractors come out at a different time to do the second phase of construction.
Most decks will be built at a level of no more than two inches from the back doorjamb down to the top walking surface. From that starting point, a deck will fall into one of three categories: it will either be considered a low-elevation deck for a house built at ground level, a mid-elevation deck when built for raised homes, or a high-elevation deck if the home is split level.
If you are having a deck built, you will have to pay for the demolition and removal of the old deck, unless you are going to take care of that yourself. While this is an additional cost, if the new deck will be placed in the exact same location, and if it is to be the same size, then you will probably save the cost of the construction of a substructure.
In order to avoid the potential for costly mistakes or disappointment, check with your homeowner’s association (if applicable), and with your local government building department to see if there are regulations which need to be followed, and to find out if a building permit is needed.
Often, building restrictions will include language to specify the minimum distance between the deck and any wells, septic tanks or their drain field, and, sometimes, between your deck and a neighbor’s house. Once you have the necessary information from the relevant authorities, you will know if there will be any impact to your intended deck location.
While the construction of your deck is taking place, a local building department inspector will need to conduct inspections to make sure the construction is up to code. Upon completion of construction for your deck project, and after the final inspection has taken place and the deck gets the official all clear, your local building department will issue a certificate of occupancy, which certifies that the structure is compliant with all relevant building codes and relevant laws.
Before construction can begin, it will need to established if there are any water lines or power lines that run underground at the intended location for your deck. Once this is known, these locations will need to be marked out before the project can be fully planned out, and before ground can be broken. The best place to start for this is with a call to 811—the US number to call before you dig anywhere.
The addition of a deck at your home will increase the value of the property, and along with that, unfortunately, your property taxes. The new total value for your property including your home and deck, based on the project cost, will be calculated using your local property tax rate.
As soon as the deck project is complete, have a tax assessor inspect the deck to make that determination. Assessors should be able to let you know of any changes in your taxes during that visit while they are onsite at your property.
Check with your insurance agent or carrier regarding your policy coverage, but according to Zebra insurance:
You need to be sure everything is covered at the full value, as referenced by the Insurance Information Institute:
Call your insurance agent to make sure your coverage is adequate for your home. The revised policy should be the replacement value for the house plus the replacement cost for the deck.
