Most homeowners don't think about soil when they choose decking. They should.
The Tri-State region shares three things: humidity, freeze-thaw cycles, and wet springs that test every material you put in the ground. A wood deck works against itself from year one—boards absorb moisture, warp, pop fasteners, and check stringers. Staining buys time. It doesn't stop the process.
That’s why Tri-State Fence & Deck, a licensed contractor in Sewell, NJ, builds with Trex. They have 20 years of experience in this region. Capped composite boards don't absorb moisture like wood—no swelling, no cupping, no fastener pop. The surface you build today still looks the same a decade from now.
Not all Trex is the same. The line you choose determines board texture, edge protection, color depth, and warranty tier.
Warranty: Trex limited residential warranty (verify current terms at trex.com)
Trex's entry composite line—solid, low-maintenance performance at the most accessible price point. Best for ground-level builds and projects where coverage area is the priority.
Warranty: Trex limited residential warranty (verify current terms at trex.com)
Fully capped on all four sides, protecting board edges from moisture infiltration—the primary failure point of entry-level composites. Strong performer across NJ's humidity and PA's freeze-thaw cycles.
Warranty: Trex's longest limited residential warranty tier (verify current terms at trex.com)
Trex's premium line—deepest grain profiles, widest color range, longest warranty tier. Integrates with Trex Transcend railing systems for a fully coordinated build. Best for primary outdoor living spaces.
