Wind is no joke in Great Falls. That’s why our decks are framed and anchored with precision using hurricane ties, reinforced joists, and weather-rated fasteners. We build with composite and pressure-treated wood that resists sun damage, moisture, and movement. Every project is designed for the region’s climate and inspected to exceed safety standards. From hilltop homes to riverside lots, we build decks that stay put and stay beautiful.

How Can We Help?
We’ve worked across neighborhoods like Skyline, Valley View, and Prospect Heights so we know the terrain, zoning, and wind exposure. Our builds are engineered to last, even in exposed areas with little natural shelter. We guide you from layout to final nail, offering honest advice and rock-solid results. Whether it’s a tight city lot or a sprawling backyard retreat, we build like it’s our own.
Anchored framing for high wind resistance
Built for sun, slope, and seasonal extremes
Trusted throughout Cascade County

Every property in Great Falls is different some homes sit on tight lots, while others overlook wide open spaces. We tailor your deck design to fit the architecture, view, and function you want. That means thoughtful stair placement, custom railings, and options for covered areas or hot tub surrounds. Whether you’re in the city or the hills, we deliver a structure that feels natural, safe, and perfectly suited to your space.

In a climate like Great Falls, the right materials make all the difference. We offer high-performance composite brands like Deckorators and Trex ideal for resisting fade, moisture, and movement. For natural options, we use cedar and pressure-treated lumber that’s sealed to handle snow, heat, and heavy gusts. Fasteners, posts, and footings are selected based on exposure and elevation. We don’t just build strong we build smart.
You won’t have to coordinate contractors or chase down permits. Our team manages the full process design, engineering, permitting, and build. We’re familiar with city requirements and build every project to exceed code. Whether you need concrete piers in rocky soil or railing systems that meet commercial specs, we get it right the first time. You’ll get consistent communication, clean job sites, and results that last.
