Composite Decks Built to Last 25+ Years in the Bay Area

A standard 300-square-foot composite deck in the Bay Area typically costs $15,000–$35,000 including materials, labor, railings, and permits. Multi-level decks, pergolas, built-in lighting, and premium materials can push costs to $40,000–$60,000+. Costs vary slightly by city and site access. We provide detailed estimates with material selections so you can adjust scope and budget before committing.

Upfront cost: composite is 20–40% more expensive than pressure-treated wood. Lifetime cost: composite wins by a wide margin. Wood decks in the Bay Area's coastal climate need staining every 1–2 years ($500–$1,500 each time), plus board replacement as they rot and warp in the fog and salt air. Composite needs virtually zero maintenance and lasts 25–50 years. Most homeowners break even on cost within 5–7 years — and never have to spend another weekend staining their deck.

Premium composite decking from Trex Transcend, TimberTech Pro, and Fiberon Goodlife lines comes with 25-year fade and stain warranties. The structural lifespan is 50+ years with proper installation. In the Bay Area's marine climate, a well-built composite deck will outlast 3–4 generations of wood decks.

In most Bay Area cities, decks attached to the house, decks over 30 inches above grade, and any deck with structural footings require a building permit. Permit processes vary by jurisdiction — SF's DBI, Marin's Community Development Agency, and each Peninsula, East Bay, and South Bay city have their own procedures. We handle the full permit process for every city we serve.

We install Trex, TimberTech, Fiberon, and Deckorators depending on your budget, color preferences, and style. Trex Transcend and TimberTech AZEK offer the most premium looks and longest warranties. TimberTech EDGE Prime+ and Fiberon Concordia are mid-range options with excellent value. We bring sample boards to your design consultation so you can see and feel the differences in your actual yard light.

Yes. We serve 31 cities across Marin, San Francisco, San Mateo, Alameda, Contra Costa, and Santa Clara counties. Coastal cities like Sausalito, Pacifica, and Daly City have the same fog and salt-air challenges as SF — composite is especially smart in those areas. We also build throughout the Peninsula, East Bay, and South Bay.

Yes — multi-level decks are one of our specialties. Marin hillsides, Oakland/Berkeley hills, and the Peninsula all have sloped lots where a simple single-level deck won't work. We design tiered decks with proper structural engineering that turn unusable slopes into usable outdoor living space.
