Trex® Frequently Asked Questions

On average, the estimated material cost for a composite deck runs from $15 - $30 per square foot (including substructure, decking, hardware and fasteners).* We recommend using our online cost calculator tool and guide to get an estimate for your project's cost. For a true cost estimate, reach out to a Trex retailer or TrexPro deck builder.

*Average price range excludes Trex Signature® decking, our luxury decking collection. Trex actual material costs and install costs can and will vary based on geographic area, site location, seasonality, design complexity, whether the product is stocked locally, and additional features such as stairs, angles, curves, lighting, etc. For most professionally installed projects, materials constitute up to one third of the total cost

Trex products offer superior durability and performance that you can't get from wood. Trex decking resists termites, won't rot, warp, or splinter-and never needs staining or painting. What's more, Trex decking is made from 95% recycled materials: That's an eco-friendly decking choice you can feel great about. To learn more please review our Trex vs. Wood page.

While most of the raw materials used in making Trex are recycled, these materials are carefully processed to ensure the highest level of quality and performance. The end result is decking that performs better than wood, lowering your cost over time through lesser maintenance. To learn more please review our Eco-friendly Decking page.

With pressure-treated wood decks, maintenance costs add up over time. Although Trex costs more initially, you'll never have to sand, stain or paint your Trex deck. Over the life of your deck, those reduced maintenance costs add up to a greater value than wood—not to mention the value of the added time spent enjoying your deck rather than working on it. If you would like to see the difference in maintenance costs for your deck of wood vs composite, visit our Decking Comparison page.

You can find Trex decking samples a number of ways. At Trex.com/Shop, you can order 12-inch samples of Trex decking in every color. Samples are $5 each, including shipping, and will be delivered to your door. You also can find 3 1/2-inch decking samples free of charge at selected local Trex dealers and retailers and through your local TrexPro® contractor.

If you've noticed any staining, scratching or fading over the years, it's likely you have early-generation decking. While our early-generation decking was groundbreaking for its time, spills and scuffs can still leave a mark. Newer-generation decking is easy to spot because of its resilience. Today's Trex decks resist blemishes with an innovative, high-performance shell that wraps around three sides of our deck boards.

Early Generation Trex Decking
Early-generation composite decking (Trex Origins®, Trex Accents®, Trex Profiles®, Trex Brasilia® and Trex Contours®) represented a breakthrough for low-maintenance and durability. While wood decking inevitably suffered splinters, warping and rotting, and required considerable maintenance, early-generation Trex never had to be stained and did not rot, warp or twist like wood. Periodic cleanings with a composite deck cleaner were far easier than the dreaded sanding and staining required to maintain wood decks. As the category evolved, this early-generation composite was offered in additional colors and with grain patterns that reflected a more natural appearance. Even so, all early generation wood-plastic composites, whether Trex or a competitor's product, were not stain, scratch or mold-free, and did fade slightly in color as they naturally weathered. To address these issues, Trex introduced a new kind of high-performance decking in 2010. As of 2014, Trex no longer manufactures any early-generation composite decking.

Newer Generation Trex Decking
Newer generation Trex deck boards ( Trex Signature®, Trex Transcend® Lineage™, Trex Transcend®, Trex Enhance®, Trex Select®, Trex Contour®) are manufactured with a high-performance shell that wraps around three sides of the composite board to protect it from the elements, providing resistance to fading, staining, scratching and mold. In addition to improved performance, the shell technology offers:

- Easier maintenance: requiring only an occasional cleaning with soap and water or a pressure washer.
- Enhanced aesthetics: richer, long-lasting color palettes and natural wood grain patterns.
- Incremental warranty protection: 25-, 35-, and 50-year limited warranties for most products.

Trex materials come with specific warranties, but it doesn’t mean they won’t last longer. When Trex launched its original product in 1998 it came with a 10-year warranty. This product is still installed in many homes and looks great after more than 25 years.

There have been many improvements in our current products and our material now is a coextruded shell that protects the board from the weather, making them last even longer than our early materials.

Trex no longer manufactures dedicated porch boards, but their high-quality decking boards can still be installed on porches, offering the same durability and low-maintenance benefits. Trex decking, designed for outdoor use, is an excellent choice for creating a beautiful and long-lasting porch surface. Its innovative composite material is resistant to fading, staining, and moisture, making it perfect for withstanding the elements on a porch. With a variety of colors and textures available, Trex decking can complement any home’s aesthetic while providing the same level of performance and style that Trex is known for. So, while Trex doesn’t have specific porch boards anymore, their decking products can easily fulfill the role and enhance any porch’s design and functionality.

Yes, a groove can be routed into a Trex decking board using the Trex Groove Cutter/Router, which can be purchased online. The Trex-branded router is specifically designed for creating grooves in Trex and other composite decking materials, ensuring a precise and clean cut for Hidden Fasteners. If you don't have access to the Trex- branded router, you can also use any 5/16” cut height carbide router bit with a ¼” shank, which is compatible for routing grooves into Trex boards.

Using the right tools, such as the Trex Groove Cutter or the recommended carbide router bit, ensures the groove is accurately milled without damaging the material. The groove will be perfectly sized for Trex's Hidden Fastener system, providing a sleek, fastener-free appearance on your deck. Whether using the Trex-branded router or a compatible bit, it's essential to follow proper cutting techniques to avoid overheating and ensure a clean, smooth finish. Always refer to the manufacturer's guidelines for optimal results when routing Trex decking.

When choosing fireplaces and fire pits, there are various options, each with distinct benefits and considerations. Here are our recommendations for safe installation on Trex decking:

For gas-burning fire pits/fireplaces, these are typically installed by cutting around the Trex decking, not directly on top of it. A fire-resistant material is placed underneath, and a protective stone wall or similar material is used to contain the fire and shield the decking from heat. Gas fireplaces should not be placed directly on Trex decking without proper protection. Propane tables are generally safe, as they don't produce downward heat. Trex Outdoor Furniture also offers propane tables to complement their furniture collections.

For wood-burning fire pits, these should not be placed directly on Trex decking unless a heat barrier is used. While we don’t have a specific recommendation for heat barriers, many are available on the market. It's important to note that Trex can soften at temperatures as low as 176°F, and the intense heat or embers from a wood-burning fire can damage the decking.

The unyielding shell of our high-performance decking—Trex Transcend Lineage, Trex Transcend, Trex Enhance and Trex Select—means it never needs painting or staining. The rich color and protective finish are engineered into the shell, and the shell is designed to remain free of rotting, splitting, splintering and insect damage for the duration of the warranty. Painting Trex decking may void your warranty.

When it comes to adding a rug or mat to your Trex deck, we highly recommend selecting a product crafted from natural fibers and materials, such as jute, sisal, or bamboo. These options not only enhance the beauty of your outdoor space but also complement the durability of Trex decking beautifully.

It's important to exercise caution with rugs made from viscose material, as the dyes used can sometimes bleed, leading to potential staining that may be challenging to remove. Additionally, we advise being mindful of rugs made from plastic (polypropylene) or those with rubber backing, as they have the potential to draw out the colorant from the decking itself. This color loss can sometimes be irreversible, and we want to ensure your deck remains as stunning as it is functional.

Trex does not endorse the use of any non-recommended fastener. If any condition occurs which is attributable to the use of a non-recommended fastener, such conditions would not be covered under the Trex Limited Warranty. Please see our Installation Guide for more information.

Trex offers a wide variety of decking options and railing configurations capable of being custom curved. When considering a deck with these characteristics, utilize the Find a Builder tool to determine which professionals in your area work on curved profiles. When planning curved railing, visit our Trex Signature® Curved Railing page for design and ordering guidance.

Note: Due to the unique composition of Trex Signature® decking we do not recommend heating and curving this product.

Trex does not recommend installing the boards on a solid surface. The recommended substructure/framing materials are pressure treated lumber or steel. Placing the boards on a solid surface does not allow for proper drainage and airflow, which is important to insure the optimal life-span of the product.

Trex does not recommend gluing the boards. If you have a specific application where you feel glue is needed, please reach out to our Customer Care Team at 800-BUY-TREX to discuss your project and whether using glue might be appropriate.

Yes, Trex decking boards can be ripped, just as you would do with wood decking using the recommended carbide tipped blade.

All surfaces can get hot on sunny days, especially the darker colored surfaces. Trex has released the Trex Transcend Lineage decking collection and Trex has added Tide Pool and Honey Grove to our Enhance collection, these boards are manufactured with heat mitigating technology, making these boards cooler to the touch than traditional composite decking.

*Although Trex decking products with heat-mitigating technology are designed to be cooler than most other composite decking products of a similar color, on a hot sunny day, it will get hot. On hot days, care should be taken to avoid extended contact between exposed skin and the deck surface, especially with young children and those with special needs.

Trex warranties our decking for fading and staining. Trex offers one of the most comprehensive warranties in the industry and you can review that here: https://www.trex.com/customer-support/trex-owners/warranty/

All Trex decking weighs between 1.88lbs and 2.51lbs per linear foot with our scalloped boards weighing slightly less than our solid profile boards.

On average, the estimated material cost for a composite deck runs from $15 - $30 per square foot (including substructure, decking, hardware and fasteners). We recommend using our online cost calculator tool and guide to get an estimate for your project's cost. For a true cost estimate, reach out to a Trex retailer or TrexPro deck builder.

*Average price range excludes Trex Signature® decking, our luxury decking collection. Trex actual material costs and install costs can and will vary based on geographic area, site location, seasonality, design complexity, whether the product is stocked locally, and additional features such as stairs, angles, curves, lighting, etc. For most professionally installed projects, materials constitute up to one third of the total cost. 

Yes, however Trex always recommends checking with your local building department. You can access our Code Evalutation report here: https://online.flippingbook.com/view/718674559/

Trex Select, Transcend and Transcend Lineage have Class B Fire Ratings and are approved for W.U.I. areas.

Trex decking is not a structural product. If you have an application that you would like to run by our team please email customercare@trex.com or call 800-BUY-TREX. We will review your project and let you know if our product would be recommended for your application.

The breadth of the Trex lineup means that there are Trex products to suit nearly any residential or commercial need. Trex decking is widely used in commercial and public projects throughout the U.S. and around the world, ranging from a landing at Mt. Rushmore and a resort in Dubai, to a pier in Philadelphia and New Jersey-shore boardwalks replacing those destroyed by Hurricane Sandy. Of course, Trex is more than just decking. The sleek profile of Trex Signature® railing works as well for commercial and multi-unit residential complexes as it does for your own backyard, while Trex Outdoor Furniture™ can be found in many coastal resorts under Trex Pergola™ installations.

Trex high-performance decking and railing products combine low-maintenance upkeep and design-minded style—all backed by our 25-, 35- and 50-year limited warranties. The protective shell technology means all of our deck boards resist staining, fading, and cracking, are resistant to scratching with Signature decking our most scratch-resistant board. Beyond that, Trex offers a variety of high-performance railing choices to meet different levels of style, performance and affordability.

Trex decking is made from 95% recycled materials, including reclaimed sawdust and recycled plastic from many common household items, such as the plastic overwrap on packaging for paper towels and toilet paper, dry cleaner bags, newspaper bags, grocery and shopping bags. Since its inception, Trex has recycled over 5 billion pounds of plastic film and become one North America's largest recyclers. To learn more, please visit our recent ESG report.

Yes, Trex decking can be used to make pool decks. Pool chemicals, such as chlorine and bromine, cause no fading or structural damage to the boards. Periodic cleaning, however, is advised.

Fiberglass-free Trex decking is approved for water contact applications. It is engineered to perform in splash zones. It can be submerged as long as the duration is intermittent for short periods. Our decking is safe for the environment and marine life. Decking should be gapped 3/8” (10 mm) width-to-width to allow for increased drainage. Stainless steel fasteners should be used. If the dock comes into sufficient contact with gasoline, we recommend grounding the dock. Saltwater can cause a haze/film over any decking surface, so periodic cleanings are advised.

Yes, all of our decking collections, made from 95% recycled material and fiber-glass free, are safe for marine life.

Trex decking should never be sanded, as doing so can compromise both its appearance and its protective qualities. Sanding alters the material’s surface, potentially affecting its ability to resist stains, scratches, and UV damage. Additionally, sanding Trex will void the warranty for any issues that arise due to this alteration. To maintain your deck’s integrity and ensure its longevity, it’s best to avoid sanding and instead follow the recommended care and cleaning guidelines. For more detailed information, visit the official Trex care and cleaning page here, How To Clean Composite Decking | Trex

No. However, Trex offers grooved edge boards, which are designed to create a flawless, secure fit with Hidden Fastener clips, while still allowing the boards to be gapped.

For more information on this decking profile explore our Trex composite board dimensions. 

Yes, Trex does offer decking boards in 20-foot lengths, though availability may vary depending on the specific product line and location. Trex decking, such as the Signature, Lineage, Transcend, Enhance, and Select collections, can be found in a range of lengths, including 20 feet, to accommodate larger deck designs and reduce the number of seams. If you're looking for 20-foot boards, it's best to check with your local Trex distributor or retailer to confirm availability and ensure the specific product you're interested in is offered in that length.

Yes, Trex does offer a 2x4 size in their Transcend Tropicals collection, specifically designed for use in a cocktail rail application. This 2x4 is perfect for adding a stylish, functional touch to your outdoor living space, creating a beautiful and durable rail that complements the high-performance Transcend Tropicals decking.

It is the more affordable of the two, backed by a 25-year warranty. In contrast, Trex Select provides a solid board option with a slightly higher price point, offering great durability and low maintenance while being backed by a 35-year warranty. Both are excellent options for budget-conscious homeowners seeking high-performance composite decking.

While all of our material will have varying scratch resistance between lines, none of our product is scratch proof.

Railings usually consist of a top and bottom rail, post cap, post cap, post, post sleeve, balusters, or an infill option like glass or mesh. Whether you are looking for more railing basics or for specifics about the Trex railing offering, we have you covered.

Railing costs vary significantly based on various deck plan details such as material, labor, and design extras (curving, cocktail rails, lighting, etc.). Use our cost calculator tool to get an idea of what the railing may cost for your next project.

The best railing for your deck is the one that will meet your aesthetic needs and practical requirements. Does the railing need to be a certain height for your local code requirements? Does it need to be a particular color for HOA standards? Do you prefer a more modern or traditional aesthetic? Still not sure? Give us a call so we can help talk through your application and find the perfect railing 1-800-289-8739.

With different levels of expertise, the easiest railing to install will be our Signature Assembled Panels and Signature Posts with Premounted Brackets. This system consists of pre-assembled parts that save you time and labor costs, without compromising the structural integrity or beauty of the classic Signature design. Watch our Signature railing install video to see the time savings the assembled panels bring to a project.

Calcium chloride or rock salt can be used to melt ice and snow on Trex decking. Care should be taken to rinse off when the weather makes this practical. Use plastic shovels (never metal) to remove snow and ice. A metal shovel can possibly chip the decking surface and void the warranty.

Trex should never be sanded. Sanding will change the appearance and protective qualities of the Trex material and will void the warranty with respect to any condition caused by sanding.

For our early generation composite decking (Trex Accents, Trex Origins, Trex Brasilia, Trex Profiles or Trex Contours), Trex does not recommend the use of a power washer. Use of a power washer will damage the decking surface and will void the warranty with respect to any condition caused by the power washing.

Trex high-performance decking (Trex Transcend, Trex Enhance and Trex Select) can be power washed. Use only a fan tip and up to a 3100 psi power washer to remove dirt and debris. The fan tip should be no closer than 8 inches (20.4 cm) away from the protective shell during use.

For color transfer issues (color transfer can happen when baluster spacers rub against balusters during installation), use Mr. Clean®, Magic Eraser® Original or Magic Eraser® Extra Power for spot removal. For small surface scratches, marks or scuffs, try Plexus® Plastic Cleaner. Never use acetone or other solvents on Transcend or Select railing.

A pressure washer with no greater than 3100 psi that has a fan attachment/adjustment and soap dispenser may be used to remove dirt, concrete dust, or other types of construction dirt. Spray deck with soap, and then follow by gently scrubbing each deck board with a soft bristle brush. Spray/rinse each individual deck board using fan tip no closer than 8" from the decking surface. RINSE THOROUGHLY. If dirty or hard water containing minerals is used for cleaning, a film-like surface may appear in spots after drying. Generally, these spots can be cleaned with white vinegar or a deck brightener product. On railing, they can be cleaned with Magic Eraser® or white vinegar. Refer to our Care & Cleaning Guide for more information on upkeep and warranties.

Trex decking requires far less maintenance than wood decking, but does require some maintenance to keep it looking good throughout the years, much like washing your car. For early generation composite decking (Trex Accents), periodic cleaning with a deck wash is required. Trex high-performance decking (Trex Transcend, Trex Enhance and Trex Select) require less work - a simple soap and water cleaning is all that is necessary to maintain the beauty of the products. Refer to our Care & Cleaning Guide for more information on upkeep.

Newer-generation Trex decking holds strong against potential damage. All of our current decking lines are scratch resistant, protecting your space against nicks, cracks and splitting. For more information, see our 2023 Limited Warranty.

Regular cleaning may minimize the effects of weathering and remove dirt, grime and other build-up. The best method of maintaining the appearance of your Trex Signature® railing is to occasionally wash it using a solution of warm water and a non-abrasive, pH neutral detergent solution. The railing surface should be thoroughly rinsed after cleaning to remove all residues. Use a soft white cloth, sponge or a soft bristle brush. DO NOT clean Trex Signature® railing with solvents such as thinners or solutions containing chlorinated hydrocarbons, esters, or ketenes.

The following cleaners are recommended for cleaning
Trex Signature® railing:
- Formula 409® Cleaner Degreaser/Disinfectant
- Spray Nine® Cleaner/Disinfectant
- Simple Green® All Purpose Cleaner
- Fantastik® All Purpose Cleaner
- Windex® Cleaner

For more details, explore our Care & Cleaning guide.

Trex DeckLighting is easy to install, and even easier to enjoy. Our plug-and-play setup is one of the most intuitive and simple lighting systems on the market. Refer to this video for the basics, and if you have any questions feel free to give us a call. We're happy to help you add lighting to your new (or existing) deck.

Trex requires that you use only the Trex transformer supplied with our lighting.

For small children and pets, our code stair kits come standard with in-between spindles, which provide less than a 4" spacing between verticals. In addition, you may want to use a gate at the top of the stair.

Many areas follow BOCA or UBC codes or variations of the BOCA or UBC codes. All Trex Spiral Stair products pass BOCA/UBC code requirements. We recommend that you contact your local building inspector to find out what code applies to your area and how that code is interpreted.

Installing a stair kit is a two-person job. For the typical do-it-yourselfer, the stairs can be installed without the help of a contractor. However, we do recommend that everyone (experienced or inexperienced) consult a qualified contractor. The contractor can help identify whether any additional structural support is necessary and required, and he or she can reroute pipes and electric lines. For two do-it-yourselfers, the spiral stairs can be assembled in about 6-8 hours. For all stair kits, you need basic hand tools and an electric drill. Before installing, we strongly recommend that you read the entire installation manual.

Galvanized stairs must weather before painting. Once weathered, contact your local paint store for the appropriate primer and paint for something that has been galvanized.

Trex Spiral Stairs offer all the space-saving advantages of traditional spiral staircases in two material choices and come with custom, high-performance composite treads made from Trex decking. Trex Spiral Stairs were developed by the leading spiral stair manufacturer in the country, The Iron Shop, under a trademark license agreement with Trex Company, Inc

A PDF of our installation manual is available here.

If you run into a problem, call Trex Spiral Stairs at 877-488-1906. Our kits are guaranteed for 25 years from date of purchase.

You will need to measure the exact height within .25" between the landing area and the top of the deck, including the width of the decking to ensure that your stairs end on the correct side.
