What Is Trex Decking?

Trex decking is a high-performance composite decking material engineered as a durable, low-maintenance alternative to traditional wood. It’s made from a blend of recycled wood fibers and plastic, creating deck boards that deliver the look of natural wood with significantly better long-term performance.

Unlike wood decking, Trex is designed to resist fading from UV exposure, staining from spills and moisture, and damage caused by rot, splintering, and insects. That makes it especially well-suited for outdoor spaces that face heavy use and constant exposure to the elements.

Trex is also one of the most sustainable decking options available. Its boards are made from up to 95% recycled and reclaimed materials and manufactured in the USA, helping reduce landfill waste without sacrificing durability or appearance.

The result is a deck that looks great, lasts for decades, and requires minimal maintenance—so you can spend more time enjoying your outdoor space and less time maintaining it.

Trex Decking vs. Wood: A Smarter Long-Term Choice

Compared to traditional wood, Trex decking offers a longer lifespan, lower maintenance, stronger resistance to moisture and fading, and lower long-term ownership costs.In Colorado’s climate, where sun, snow, and freeze-thaw cycles take a toll on wood, Trex® composite decking was engineered to deliver consistent performance without constant upkeep.

Maintenance

Wood decks require regular sanding, staining, and sealing. Trex decking never needs it—just occasional cleaning with soap and water.

Durability

Wood decks often last 10–15 years before major repairs. Trex decking resists rot, moisture, insects, and cracking and is backed by warranties up to 50 years.

Appearance

Wood fades quickly and needs refinishing to look good. Trex decking is engineered to resist fading and staining, keeping its color year after year.

Comfort & Safety

Aging wood can crack and splinter. Trex won’t—providing a smooth, barefoot-friendly surface that stays comfortable for families and pets.

Cost Over Time

While wood may cost less upfront, ongoing maintenance adds up. Over time, wood decks can cost significantly more than Trex to maintain and repair.

Sustainability

Wood contributes to deforestation and chemical treatments. Trex decking is made from up to 95% recycled materials, reducing environmental impact.

The bottom line: Wood demands constant upkeep. Trex is designed so you can enjoy your deck, not work on it.

FAQs About Wood Decking

Does Trex get hot in the sun?

Like all decking materials, Trex can warm in direct sunlight. Lighter colors stay cooler, and proper design (shade, airflow) makes a big difference.

How long does Trex decking last?

Trex decking is backed by warranties up to 50 years, depending on the product line.

Is Trex decking slippery when wet or snowy?

Trex decking is designed with slip-resistant surfaces that provide better traction than many wood decks, even when wet. That said, snow and ice should still be cleared promptly for safety.

Can you paint Trex decking?

Trex does not recommend painting or staining its decking boards. Trex is designed to maintain its color and performance without coatings, and applying paint or stain can affect appearance, traction, and warranty coverage.

How do you clean Trex decking?

Trex decking is easy to clean. For routine maintenance, use mild soap, warm water, and a soft-bristle brush to remove dirt and debris. For tougher stains, a composite-safe cleaner can be used.

Can Trex decking be installed over an existing wood frame?

In many cases, yes. If the existing frame is structurally sound and properly spaced, Trex decking can be installed over it—but a professional inspection is recommended before moving forward.
