Alliance Deck Builders of Missouri delivers outdoor living spaces tailored to homes and businesses throughout the state. Whether it’s a cedar deck in Columbia, a composite rooftop lounge in St. Louis, or a screened-in porch in Springfield, we combine design, durability, and code-compliant craftsmanship. From high-traffic restaurants to quiet backyard escapes, we build structures that match Missouri's terrain, weather, and local building codes.

How Can We Help?
From the Ozark hills to St. Louis rooftops, we build decks that meet the needs of Missouri homeowners and commercial clients alike. Our team understands the structural requirements needed to support decks in freeze-thaw zones, handles zoning for covered patios and rooftop installations, and designs for both function and aesthetics. Clients trust us to guide material selection—from weather-hardy composite to classic cedar—based on Missouri’s variable humidity and sun exposure.




We help clients select materials suited for the local climate and use case. Cedar offers a warm, natural look with strong resistance to insects and rot—perfect for garden or poolside settings. Pressure-treated wood remains a cost-effective favorite for standard builds, while composite decking provides unmatched lifespan and low maintenance. Our guidance ensures you get beauty, safety, and function—whether you’re installing a rooftop lounge in Kansas City or a wraparound deck in Jefferson City.


















Missouri’s mix of seasonal extremes demands decks that can handle everything from winter freeze to summer heat. We account for ground shifts, water runoff, and material longevity in high-UV zones. Whether building on hillsides, around pools, or above rooftops, our crews engineer for durability and safety. Plus, we’re well-versed in local permit rules, HOA restrictions, and historic district guidelines—ensuring your project is approved and built to last.

Whether it’s a small platform or a multi-story structure, we follow strict build protocols, local permitting rules, and industry best practices. We also handle all necessary approvals and inspections—so you can focus on enjoying your new outdoor space.
We don’t just build decks—we guide you through the entire process. It starts with a site visit and custom design. Once plans are approved, we schedule your project, order materials, and assign a dedicated crew. You’ll receive progress updates and a final walkthrough to ensure everything meets your expectations. It’s deck building made simple, with no guesswork or stress.

Your deck’s durability starts with the materials we recommend. We use top-tier brands like Trex, TimberTech, and Fiberon for composite builds, and only kiln-dried cedar or ACQ-treated lumber for wood decks. Every material is chosen for weather resistance, code compliance, and visual impact—so your deck looks great and performs even better.
