What Customers Are Saying

Customers overwhelmingly praise the decking for its realistic wood-grain appearance, rich color tones, and exceptional durability that resists scratching, fading, and weather damage. Many highlight the maintenance-free surface eliminates staining and painting, saving time and cost long-term. Reviewers note the boards are easy to cut, drill, and install with a hidden fastener system creating seamless surfaces. Several customers report the material remains beautiful after five years of use. A few mention minor issues with board straightness or color appearing darker than online images, though most consider these drawbacks insignificant against the overall quality and convenience.

Bulletproof

Would Recommend

These are amazingly dense and correspondingly heavy. However, I suspect that these will be around longer than the treated lumber that they are installed on. They have a very nice embossed wood grain texture and look that also serves as a slip-resistant finish. I chose the solid planks because I was building stairs and needed the solid edge instead of the hidden fasteners on the stair treads. I highly recommend the C-Deck Composite Deck Screws from Screw Products, Inc. with the color matched ...

Beautiful, Strong, and Long Lasting!

Built my back deck with the entire Trex Transcend Composite Deck Boards! It looks beautiful and the best part is the hidden hardware. There are no nail/screw holes showing because the hardware fits within the grooves! I can also put full faith in the longevity of the deck because I know the composite material wont rot! Would buy again and I recommend it to anyone else who wants a high quality deck!

Fits the bill

Would Recommend

Used for porch step treads and the Trex is the thing for this application. Winter will give a greater perspective but, I am not worried that these boards will be less than I anticipate.

Solid product

Would Recommend

I installed this as a perimeter around a different style of Trex so that Cortex hidden fasteners could be used to secure it in place. It as a natural wood texture and deep, rich color. I would definitely recommend this line of Trex decking.

Feels Tough, Dark Color

Would Recommend

[This review was collected as part of a promotion.] After looking at, walking on, and spilling liquids on this deck board sample I would definitely consider it if I was in the market for new decking for our home. The thing I like the most is that the board itself is covered with a plastic-like cover, making it weatherproof. It also means no more cleaning and painting every year. It does resemble a real-life board but you can tell it is not. It appears to be made of a thick press board that is co...

This deck board is really sturdy!

Would Recommend

[This review was collected as part of a promotion.] I was sent a piece of deck board. This color is a dark brown. It is very heavy. Very good quality. We have a yellow home. It looks nice. They advertise fade and stain resistance for 25 years. This is a high performance composite. It will make a beautiful deck!

Another Durable Product

Would Recommend

[This review was collected as part of a promotion.] It's a very durable board. It doesn't scratch easily, nor splinter easily either. It's a very dense quality. Appears to have a good UV coating. Very heavy weight per foot. I believe that you'd have to have a very sturdy frame to accommodate this material.

A Smart Choice

Would Recommend

[This review was collected as part of a promotion.] Trex transcend deck boards are beautiful, tough, and good for the environment. They are 95 percent recycled products, and have a 25-year warranty. Lava Rock is a gorgeous deep brown with darker color variations and a natural looking grain. This product is pricey, but well worth the investment.

Beautiful!

Would Recommend

[This review was collected as part of a promotion.] I received this sample to test. This product is awesome. I can only imagine how beautiful it would look on an entire deck. The product is very sturdy and would probably last for years. It is looks just like wood grain. It is heavyweight. The tongue and groove assembly will make it very easy to install. The lava rock color is a realistic dark espresso wood stain color. Definitely a great option for a maintenance-free deck!!
