Low-Maintenance, Long-Lasting, Beautiful
Composite Deck Installation in California
The Smarter Decking Choice for California Homes
Why Composite Decking Beats Wood for Longevity
Composite decking combines the best of durability and design. Resistant to moisture, termites, fading, and California’s harsh sun, these boards keep their color and shape for decades with virtually no maintenance. You won’t need to seal or sand—just rinse occasionally. Ideal for coastal cities, dry inland zones, or high-traffic backyards, composite materials offer long-term value while maintaining the look of real wood

Benefits of Our Composite Deck Installations
We don’t just install composite decks—we engineer them for comfort, beauty, and strength. Each project is tailored to your space and needs, from ground-level patios to rooftop decks or hillside platforms. Composite boards stay cooler in summer, resist mold, and don’t split or crack like wood. With dozens of textures, grains, and colors to choose from, your deck can match your style without the maintenance headache.

Available in wood-look and modern finishes

Composite Deck Systems That Fit Your Lifestyle
We work with your layout, home architecture, and HOA rules to deliver a customized composite deck that blends style and function. Whether you want wraparound stairs, built-in benches, planter boxes, or lighting, our team integrates each element into your deck design. We install code-compliant framing, hidden fasteners for a clean look, and durable trim for a polished finish. Everything is built to meet California’s structural standards—and your expectations.
Framing That Matters Just as Much as the Boards
Engineered Substructures for Composite Decking
A composite deck is only as strong as the structure beneath it. That’s why we build every frame using pressure-treated lumber or steel rated for long-term performance. We use moisture barriers, joist tape, and code-compliant spacing to prevent sagging, rotting, or fastener issues. For rooftop or elevated decks, we install waterproof membranes and drainage layers to protect your home and maximize lifespan. Every detail matters, from ledger bolts to post anchoring.

Get Answers Before You Build
Common Questions About Composite Decking
Thinking about composite? Here’s what California homeowners ask most. Want help picking a product? We’ll guide you.
Is composite decking worth the higher upfront cost?
Yes. It lasts longer, requires less maintenance, and holds its value better than most wood decks over time.
Can I pressure wash composite decking?
Yes—just use a fan tip and low pressure (under 1,500 psi) to avoid damage. Most just need a rinse or mild soap wash.
What colors and finishes are available?
Dozens. From warm wood tones to sleek grays, we show samples from Trex, TimberTech, and Fiberon during design.
Do composite decks get hot in the sun?
Some brands offer cooler surface technology. We help you select lighter colors and install with shade planning in mind.
