Why Big Sky Homeowners Trust Us With Their Decks

Building a deck in Big Sky isn't like building one anywhere else. At 6,800 feet, your deck faces UV intensity 25% higher than at sea level, 200+ inches of annual snowfall, and freeze-thaw cycles that destroy inferior materials. Every deck we build is engineered for these conditions.

We've built decks overlooking Lone Mountain from Mountain Village chalets, multi-tier entertainment decks in Meadow Village, and wraparound decks along the Gallatin River corridor. We understand how to orient a deck to frame the Spanish Peaks at sunset while blocking prevailing northwest winds.

Built for Montana Mountain Living

Our decks are built to survive. We engineer every structure above Gallatin County's 60+ PSF snow load requirements, set foundations below the 48-inch frost line, and use steel-reinforced framing that handles the weight of a February snowpack.

Local expertise. We know Big Sky's microclimates, from the wind exposure at Mountain Village to the sun angles in Town Center
Mountain-grade materials. We spec TimberTech AZEK, Trex Transcend, and Ipe hardwood rated for high-altitude UV and heavy snow
Full permitting. We handle Gallatin County permits, resort tax coordination, and code compliance from start to finish
View optimization. Cable rail systems and strategic deck orientation that maximize your mountain panoramas

From Consultation to Completion

Every project starts with an on-site visit where we assess your property's terrain, sun exposure, wind patterns, and view corridors. We've worked on everything from gentle meadow lots near Big Sky Town Center to steep hillside builds requiring helical pier foundations.

Our designs go through structural engineering review before permitting, ensuring your deck exceeds code requirements for snow load, seismic, and wind uplift.

Our Process

From Consultation to Completion

A clear, structured approach from first conversation to final walkthrough.

Step 01

On-Site Consultation

We visit your property to assess terrain, elevation, sun exposure, and views. In Big Sky, every deck orientation matters — whether you're framing Lone Mountain or the Spanish Peaks.

Step 02

Design & Engineering

Our designs account for Gallatin County's 60+ PSF snow load requirements and Big Sky's freeze-thaw cycles. We select materials rated for 6,800+ feet of elevation and UV exposure.

Step 03

Permitting

We handle all Gallatin County building permits and coordinate with Big Sky's resort tax office. Our familiarity with local code requirements means faster approvals.

Step 04

Foundation & Framing

Helical piers or concrete footings set below the 48-inch frost line, steel-reinforced framing sized for heavy snow loads, and proper drainage grading for spring snowmelt.

Step 05

Decking & Finishing

Installation of your chosen decking material with hidden fastener systems, integrated lighting, and cable rail systems that preserve your mountain views.

Step 06

Final Inspection & Walkthrough

County inspection, detailed maintenance guide specific to your materials, and a walkthrough covering seasonal care for Big Sky's climate.

FAQ

Frequently Asked Questions

How long does a deck build take in Big Sky?

Most custom decks take 3-6 weeks from breaking ground to final inspection. Our building season runs from late May through October, limited by ground thaw and early snowfall. We recommend booking your spring consultation by February to secure a summer build slot.

What materials handle Big Sky's heavy snow loads?

We engineer every deck for Gallatin County's 60+ PSF ground snow load requirement. Composite materials like TimberTech AZEK and Trex Transcend handle freeze-thaw cycles without cracking or warping. For structural framing, we use steel-reinforced joists and posts rated well above code minimums.

Do I need a permit for a deck in Big Sky?

Yes. Gallatin County requires building permits for all attached and detached decks. Permits cover structural engineering, setback requirements, and snow load compliance. We handle the entire permitting process, which typically takes 2-3 weeks for approval.

Can you build on steep terrain?

Absolutely. Many Big Sky properties sit on hillsides with significant grade changes. We use helical pier foundations and multi-level deck designs to work with the terrain rather than against it, often turning a challenging slope into a dramatic multi-tier outdoor living space.

What's the best decking material for high elevation?

At 6,800+ feet, UV intensity is roughly 25% higher than at sea level. Capped composite products like TimberTech AZEK offer the best UV resistance without maintenance. Ipe hardwood is the premium natural option — its density naturally resists UV graying longer than any softwood.

Do you serve areas outside Big Sky?

Yes, we serve the greater Gallatin Valley including Bozeman, Gallatin Gateway, West Yellowstone, and Ennis. Most of our projects are within an hour of Big Sky proper. We also work in Moonlight Basin and the Yellowstone Club for members.
