Built Strong.
Built to Last.

Seattle homeowners have learned the hard way that cedar decks require constant maintenance in the Pacific Northwest — annual sealing or staining, board replacement as rot sets in, and regular cleaning to fight moss and mildew. Composite decking eliminates all of that. What composite decking offers Seattle homeowners: • No annual staining or sealing — ever • Won't rot, warp, crack, or splinter in Seattle's rain • Slip-resistant surface texture — safer in wet conditions • No moss or mildew penetration (composite doesn't provide organic substrate) • Fade and stain warranties of 25–30 years from leading brands • Lower lifetime cost than cedar despite higher upfront price

Composite decking costs more upfront than cedar but less over 20 years when you factor in maintenance. 2026 installed cost estimates (Seattle metro): • Entry-level composite (Trex Enhance): $22–$30/sq ft • Mid-range composite (Trex Select, Fiberon): $28–$38/sq ft • Premium composite (Trex Transcend, TimberTech): $35–$50/sq ft For a typical 300 sq ft deck: • Entry composite: $6,600–$9,000 • Mid-range composite: $8,400–$11,400 • Premium composite: $10,500–$15,000 Compare to cedar: $10,000–$18,000 for same size, plus $500–$1,500 every 2–3 years in maintenance. The 20-year total cost of ownership for composite is typically lower than cedar.

Composite decking requires a properly engineered frame — this is where many budget contractors cut corners and create problems. Key framing requirements for composite decks: • 16" on-center joist spacing maximum for most composites (not the 24" typical for cedar) • Some premium composites require 12" centers — check manufacturer spec • Pressure-treated lumber rated for ground contact where posts contact soil • Stainless or double hot-dipped galvanized fasteners — standard galvanized corrodes in Seattle's climate • Hidden fastener systems (like Trex Hideaway) for a clean surface without screws showing • Proper blocking at all board ends to prevent sagging We frame every composite deck to manufacturer specifications — not just to pass inspection, but to ensure the deck performs correctly for its 25-year warranty period.

One of the advantages of composite decking is the huge range of colors, textures, and design possibilities. Design options we offer: • Picture frame borders with contrasting color boards • Diagonal and chevron decking patterns • Multi-level deck designs • Built-in seating and planters with matching composite fascia • Railing systems: composite, aluminum, cable, glass panel • Fascia boards to cover the deck's perimeter framing • Lighting integration (post cap lights, riser lights, under-rail lights) We design every deck in-house and present you with a detailed plan before construction begins.
