Why Trex Decking

  • The Smarter Alternative to Wood 
    Trex has helped redefine outdoor living by delivering the natural beauty of wood without the ongoing upkeep. Trex composite decking is engineered for durability and designed to stand up to years of sun, weather, and everyday use. 
  • Exceptional Durability 
    Trex decking is engineered with innovative materials that resist many of the common problems associated with traditional wood decking, helping homeowners enjoy their outdoor spaces longer. 
  • Low Maintenance 
    Unlike wood decks that require regular staining, painting, and sealing, Trex decking is designed to minimize maintenance, allowing you to spend more time enjoying your deck and less time maintaining it. 
  • Complete Outdoor Living Solutions 
    Trex offers more than decking. Coordinated railing systems, lighting, and accessories work together to create a finished, cohesive outdoor space that complements your home.
  • Beautiful Design Options 
    Choose from a variety of colors, styles, and railing options to create a customized outdoor living environment that matches your vision and lifestyle. 
  • Trusted Performance 
    Trex products are designed to deliver decades of enjoyment and are backed by warranties that give homeowners added confidence in their investment.
