Strong Foundations Start Below the Surface
Built to Withstand Montana’s Tough Terrain
Our builds begin with what you don’t see deep footings, frost-rated piers, and proper drainage systems. Montana’s varied soil types, from Butte’s clay to Whitefish’s gravel, require custom footing strategies that ensure long-term structural integrity. We assess slope, freeze depth, and wind load before we ever lay a board. This proactive planning prevents settling, cracking, and costly future repairs. It’s not just about building decks—it’s about building them to last through every Montana season
Your Deck, Your Style No Templates Here
Tailored Designs That Reflect Your Vision
We don’t believe in cookie-cutter layouts. Every deck we build starts with your ideas, your lifestyle, and your property’s unique layout. Whether you want a built-in bench, integrated lighting, or a grilling zone, we create detailed CAD renderings before the first board is cut. This custom approach ensures that your outdoor space fits your needs and blends beautifully with your home’s architecture. No mass-produced kits—just handcrafted work by experienced builders who live and work right here in Montana.
We Build With Permits, Codes & Peace of Mind

Answers to Common Questions
Montana Deck Building: What to Know Before You Start
Montana’s climate, soil, and code requirements make deck building more complex than in other states. Here are answers to the questions we hear most often from local homeowners and business owners.
What types of decks hold up best in Montana’s climate?
Composite decking like Trex and TimberTech offers excellent resistance to moisture and temperature swings. Cedar is also a great natural choice with proper sealing.
Do I need a permit to build a deck in Montana?
Yes, most decks especially those over 30 inches off the ground require a permit. We handle the permitting process for every project.
How long does it take to build a custom deck?
Most residential projects take 1–3 weeks depending on complexity, weather, and permitting. Commercial decks or multi-tiered builds may take longer.
Can you build decks in the winter?
Yes. We build year-round using frost-rated footings and winter-ready materials. Some processes may take longer during freezing conditions.
