Composite Decks
Low-maintenance composite decking installed with precision — picture-frame borders, hidden fasteners, and color combinations that complement your home. Built to look beautiful for decades, no annual staining required.
Custom Stairs & Railings
Mitered composite treads, wrapped risers, and clean aluminum railings — every step engineered to last through Montana winters.
Elevated Decks & Full Builds
From framing to final railing — full elevated decks with covered patio space below. Craftsmanship you can trust.
Front Entry Decks & Steps
Custom wrap-around entry decks with mitered picture-frame borders and clean angled steps. Warm composite tones designed to complement the character of your home.
Siding & Exteriors
Board-and-batten, lap, cedar, fiber cement, and metal siding — installed with proper weather barriers and flashing. Exteriors built to shed Montana snow and stay sharp season after season.
Framing & Craftsmanship
Behind every finished deck is a rock-solid frame. Full-flashing tape on ledgers and joists, engineered footings, and precise layout — the details you don't see are what make a deck last 30+ years in Montana weather.
