Golden State Builders Group is a trusted name among deck builders in Walnut Creek, CA, offering expertly crafted custom decks that elevate outdoor living across the East Bay. We specialize in redwood, cedar, and composite decks built for both beauty and longevity, designed to withstand local weather patterns, seismic standards, and fire safety requirements.
Whether you’re dreaming of a cozy redwood patio for family gatherings or a multi-level composite deck for large-scale entertaining, our local team brings precision, creativity, and reliability to every project. Homeowners choose us because we combine craftsmanship, technology, and local insight to deliver outdoor spaces that are built to last.
Outdoor living is an integral part of California’s lifestyle, and Walnut Creek’s sunny climate makes it the perfect setting for year-round enjoyment. With an average of 260 sunny days annually and mild temperatures ranging between 45°F and 85°F, decks here must balance UV resistance, durability, and fire safety (U.S. Climate Data).
A professionally built deck not only enhances the comfort and visual appeal of your home but can also increase property value by 65–75% ROI, according to Remodeling Magazine’s Cost vs. Value Report. With average home prices exceeding $915,000 (Redfin, 2025), investing in quality outdoor spaces offers both immediate enjoyment and long-term equity.
Our process begins with an in-depth consultation. We discuss your home’s layout, design preferences, and how you plan to use your deck. Whether it’s for hosting, relaxing, or improving energy efficiency through shade, we create a customized solution that aligns with your goals.
Golden State Builders Group has earned its reputation through reliability, craftsmanship, and commitment to quality.

Choosing the right deck material is essential to long-term performance and maintenance ease. Golden State Builders Group provides a variety of high-performing materials tested for the Walnut Creek climate.
Composite decking is the leading material for homeowners seeking low maintenance and lasting beauty. Brands like Trex, TimberTech, and Fiberon offer fade-resistant colors, realistic wood-grain finishes, and a life expectancy exceeding 25 years. Composite materials are non-splintering, insect-resistant, and do not require staining or sealing, making them ideal for Walnut Creek’s dry summers and mild winters.
We recommend composite decks for homeowners prioritizing sustainability, as many boards are made from 95% recycled materials.
California redwood and Western red cedar remain timeless favorites for their natural charm and warmth. Redwood decks can last 20–30 years with proper sealing and maintenance, while cedar decks provide a lighter aesthetic with natural oils that deter pests. Both options perform well in Northern California’s climate but require periodic care to maintain color and water resistance.
Our team sources lumber from responsibly managed forests and applies protective finishes that extend the deck’s lifespan by up to 50% longer than untreated installations.
The foundation of any quality deck lies in its frame. We use pressure-treated lumber to reinforce structural integrity and meet California’s seismic safety standards. These treated beams resist rot, mold, and warping, ensuring your deck remains strong through seasonal temperature changes.
