Alliance Deck Builders of Colorado delivers beautifully crafted outdoor spaces tailored to how you live. From composite decks to multi-level custom builds, we work across every major city in Colorado to create functional, long-lasting environments for your home or business. Whether you're expanding your entertainment space or adding value to your property, our team brings decades of hands-on experience, expert craftsmanship, and code-compliant construction to every project.
How Can We Help?
With Colorado's unique climate and elevation changes, deck building isn’t one-size-fits-all. That’s why we use materials designed for durability—like pressure-treated wood, cedar, and weather-resistant composite decking from brands like Trex and TimberTech. Our seasoned team understands snow load requirements, wind exposure, and HOA standards across cities like Denver, Fort Collins, and Colorado Springs. From design to final inspection, we handle every detail with precision and transparency. Whether it's a backyard refresh or a full commercial deck build, we make outdoor living exceptional.
From urban rooftops in Denver to sprawling backyards in Fort Collins, our work spans a variety of deck styles and settings. We build for the view, the function, and the long haul—using materials that last and craftsmanship that speaks for itself. Below are just a few recent projects showcasing what we do best.
Every deck we build is engineered with long-term performance in mind. Colorado’s freeze-thaw cycles, dry air, and elevation shifts demand specific construction techniques—and we know what holds up. Our builders use reinforced framing, correct fasteners for each material, and handle drainage and ventilation properly. We’ve spent years building a reputation city by city, and we stand behind everything we build with warranties and real customer support.

We’re not just deck builders—we’re your permitting partner. Our team handles code compliance, HOA approvals, and city inspections across Colorado, so your deck is legal, safe, and long-lasting. We regularly work with regional building departments in Denver, Pueblo, and Colorado Springs to make sure your project passes the first time. No surprises, no delays—just the right build done right.
Our process starts with a free design consultation, where we take measurements, listen to your ideas, and walk your property to understand the layout and sun angles. Once your plan is approved, we manage the full build—from demolition and framing to trim work and final inspection. Whether it’s a rooftop restaurant deck or a backyard multi-tier cedar build, your dedicated crew handles everything. We never subcontract key structural work.
