Cosman Construction, based right here in Boulder, has years of hands-on experience building custom decks that stand the test of time.

We understand that no two homes—or homeowners—are the same, which is why we take the time to get to know your specific goals, preferences, and how you envision using the space. From a spacious multi-level deck designed for entertaining to a cozy nook for reading and relaxing, every deck we build is tailored to fit your life.

Living in Boulder or Longmont means you’re surrounded by natural beauty—from the Flatirons to tree-lined neighborhoods—and your deck should take full advantage of that. Imagine stepping outside onto a custom-built space that feels like a natural extension of your home, offering mountain views, a place for barbecues, or just an open-air retreat. At Cosman Construction, we manage the entire process from start to finish, including permitting, custom design, and expert construction. That means less stress for you and a finished deck that’s ready to enjoy right away.

One of the things that sets us apart from national chains and general contractors is our deep connection to the Boulder area. We’re not just working here—we live here, too. That local expertise matters when it comes to navigating zoning laws, weather patterns, and HOA guidelines that can affect your deck project. We build every deck with Colorado’s changing seasons in mind, using proven construction methods and durable materials that hold up through snow, sun, and everything in between. Every build is custom, never prefabricated or one-size-fits-all.

When it comes to materials, Cosman Construction offers a full range of options to match your style and your budget. Want the warm, classic look of natural wood? We’ve got you covered. Looking for low-maintenance composite decking that still looks amazing year after year? We can do that, too. We also work with eco-friendly materials for those looking to minimize their environmental impact. No matter your choice, we’ll help you select the right combination of durability, aesthetics, and value for your new deck.
