Quick Answer: For Bay Area homes, composite decking (Trex, TimberTech, Fiberon) is the better long-term choice. It lasts 25-30+ years with no staining, painting, or sealing. Pressure-treated wood costs 30-40% less upfront but requires annual maintenance and lasts 15-20 years. For Bay Area coastal areas with salt fog, composite significantly outperforms wood in longevity.

Best Composite Decking Brands for Bay Area 2025
- Trex Transcend: Most popular brand in the Bay Area. Excellent color stability. Lifetime limited fade and stain warranty
- TimberTech Azek: Premium all-PVC board (no wood fiber). Best moisture and mold resistance — ideal for foggy coastal areas (Alameda, Pacifica, Half Moon Bay)
- Fiberon Paramount: Mid-price; good performance; capped composite construction
- MoistureShield Elevate: Specifically designed for high-moisture climates; rated for ground contact and below-grade installation
When to Choose Wood Instead
- You’re on a tight budget and plan to sell the home in 3-5 years
- You prefer a completely natural material and are committed to annual maintenance
- You want to paint the deck (composite cannot be painted)
- You’re matching existing wood decking on a historic home
