What Customers Are Saying

The Trex composite deck boards are a durable and low-maintenance option. Customers praised the solid construction, consistent quality, and easy upkeep. The color options, particularly the pebble grey, were well-received. However, some users reported issues with scratches, staining, and the boards becoming very hot to the touch. Installation challenges, such as warping and uneven boards, were also noted by a few customers. Despite these drawbacks, the majority of customers were satisfied with the long-lasting performance of the product compared to traditional wood decking.

Great maintenance free decking

Would Recommend

I have used Trex decking on several projects and have been very pleased with the results. It is easy to install, wears well and does not fade in the intense Florida summer sun. Cleaning is easy with soap and water and light pressure washer spraying. I highly recommend for decking, especially in a high humidity climate.

Trex Composite Deck Board

Would Recommend

We redid our small deck and our front porch with grey composite and white railing to match our window trim. It's jewelry on our house! It looks beautiful. We are looking forward to not needing to do anything more that wash it off in the spring!

I have used this product previously with good results. This order however was placed over 2 week ago and I still have not received it. I called my local store yesterday morning to inquire about delivery and have not yet received an answer (a day and a half later). Not too happy now.

Trex Select

Would Recommend

Ordered this product on line to finish deck that was being built. Originally bought larger quantity of 16' boards from a different supplier. Ordered these as did not need the 16' lengths to finish project. Boards matched others perfectly and installed in no time. Could have gone with a cheaper line of composite board but after looking around at some other decks found they do not hold up very well as cheaper products were cracking and splintering.

Love the color and the feel

Would Recommend

[This review was collected as part of a promotion.] This sample was the first of this kind I had ever seen. The quality of the board is great. I would definitely use this to replace decking or to build a new deck. I even wet the the sample piece to see how water would do on it. The water beaded up and was easy clean up. The best part is not having to stain the deck every year.

No need to stain your deck

Would Recommend

[This review was collected as part of a promotion.] What I love about this composite deck board is there is no need to sand and stain the deck. I have my Trex composite deck for over 8 years and it looks still brand new. Not once did I have to worry about the color of my deck fading or breaking. So, this new color pebble grey deck board sample makes me want to have a new deck due to the new grey grain look. The board is strong and very durable. I can totally vouch for this product.

Heavy and nice

Would Not Recommend

[This review was collected as part of a promotion.] I received this sample board, and of course, it's a little hard to review a sample deck board since I didn't install a full deck with this product. However... the board arrived in a flat package and the board had a sizable dent/nick on it. Which leads me to believe that if I dropped something heavy onto the deck, it would dent it. And unlike wood, i don't think you can sand or fix that with this composite material. That said... it's super heavy...
