What Customers Are Saying

Customers overwhelmingly praise the decking for its realistic wood-like texture, rich coloration, and solid, heavy construction that feels premium and long-lasting. Many highlight exceptional durability, noting resistance to fading, warping, and damage from pets and weather. Reviewers appreciate the maintenance-free nature and hidden fastener system that creates a clean, seamless look. Most find installation straightforward, though some note pre-drilling is necessary due to material density. A few report minor color inconsistencies between boards or occasional warping, and some mention the weight makes handling challenging. Overall, customers consider it a worthwhile investment that exceeds expectations.

Great Product

Would Recommend

I have a 1200 square foot deck that I am redoing in sections with the Trex Trancend Island Mist. Similar to other composite products I have to work with the temperature and direct sun light have an impact on the length and even the width. Once you know this you work around it and it works. Very happy with final look of this product. Our front porch is the same material and it is holding up perfectly.

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!!
