The Superiority of Trex Composite Decking in Southern California
Traditional wood decks demand endless cycles of sanding, chemical stripping, and water-repellent staining every spring. In the intense San Diego sun, untreated wood boards crack, cup, and snag bare feet with painful splinters.
As shown in this Del Mar installation video, our master carpenters build composite decks engineered for decades of barefoot enjoyment:
1. Hidden Fastener Clip System
Gone are the days of rusted drywall screws or nails popping up through deck boards. We install specialized hidden fastener clips into the grooved edges of each Trex plank. This leaves an ultra-clean, screw-free surface that feels like indoor hardwood flooring outdoors.
2. Butyl Joist Tape Protection
The number one reason outdoor decks fail prematurely is water trapped between the deck boards and the wooden substructure. Before laying a single board, our carpenters apply waterproof butyl joist tape across all framing members, protecting structural screws and blocking moisture from rotting the joist crowns.
3. Complete Resistance to Rot, Termites & Salt Spray
Unlike timber that absorbs moisture and hosts subterranean termites, Trex’s protective outer shell repels rain, morning marine layer mist, and airborne sea salts. Spilled wine, barbecue grease, and sunscreen wash away cleanly with warm water and soap.
4. Seamless Architecture Alongside Pergolas & Trellises
Notice how this elevated walkway connects seamlessly to adjacent shade pergola rafters. Whether building a narrow balcony cat-walk, a terraced multi-level deck, or an expansive outdoor kitchen platform, composite decking integrates flawlessly into modern architectural hardscapes.
