Montana Businesses Need Strong, Safe, Stunning Decks
Commercial Deck Construction in Montana
Load-Rated, Weatherproof, and Public-Ready
What Sets Commercial Decks Apart
A commercial deck isn’t just a larger version of a residential build. These structures require stronger framing, heavier-duty hardware, ADA-compliant features, and design that fits both code and customer flow. We’ve built rooftop lounges, brewery patios, dining decks, and walkways that hold up under foot traffic, weather, and local inspections. From permits to finish, we manage every detail to make your space usable, safe, and attractive.
Safe, Stylish, and Built to Bring People In
Where Commercial Decks Make the Biggest Impact
A great deck draws in guests. Whether it’s a rooftop view, a shaded patio, or a sidewalk café extension, outdoor seating drives revenue. We build decks that work hard for businesses easy to clean, engineered to handle weight, and made to impress. From concrete footers to commercial railings and stair systems, we make sure your new deck checks every box.
ADA ramps, compliant stairs, and proper egress
Commercial-grade hardware, railings, and finishes
Durable surfaces that clean easily and resist wear
Your Business Is Unique. So Is Your Deck.
Custom Deck Solutions for Public-Facing Spaces
No two commercial decks are the same. That’s why we start with layout planning, traffic patterns, and intended use. Hosting diners? You’ll need room for tables, walkways, and wait staff. Rooftop bar? Wind load and waterproofing are critical. Every deck we build is tailored to your operations, your foot traffic, and your climate exposure. We build it to last and to work.
Built for Weather, Weight & High Foot Traffic
Materials That Perform in Public and Montana Conditions
We use commercial-rated composites, sealed wood, and non-slip surfaces that stand up to spills, snow, and shifting temperatures. Substructures are framed with larger joists, tighter spacing, and extra bracing for live load requirements. Whether you're serving food, hosting events, or creating retail access, our decks are ready to handle it.
From Permits to Final Inspection We Handle It All
Fully Managed Commercial Deck Construction
Commercial projects need more than just tools they need paperwork. We provide engineered drawings, file permit applications, and coordinate with fire marshals and code officials. Our crews build to meet every safety requirement and deliver a finished deck that opens on schedule. No delays, no missed inspections just a space that’s ready for guests.
