What Customers Are Saying

Customers overwhelmingly praise this composite decking for its rich, consistent coloration and modern aesthetic, with many noting it outperforms traditional wood. Reviewers consistently highlight the ease of installation, particularly with hidden fastener systems, and emphasize durability—many report decks looking new after years of use. The low-maintenance nature and long-term value justify the higher upfront cost for most. A few mention the surface becomes very hot in direct sunlight, and some report isolated board damage, but these concerns are minimal compared to widespread satisfaction.

The supplier to Lowe's failed to deliver it to Lowe's so while I had to reschedule the contractor it wasn't really Lowe's fault. I had an earlier order for twelve -12ft. boards that went smoothly. These two 12ft boards were for my original measuring error and the contractor's cutting errors.
