Montana’s wide temperature swings, heavy winds, and sun exposure can destroy poorly built decks in just a few seasons. That’s why we use pressure-treated frames, composite decking, and reinforced fasteners made to endure Billings’ weather extremes. From the rimrocks to the valley floor, our projects are engineered for long-term stability and visual appeal. Whether you’re battling hail or blazing sun, we design your deck to thrive not just survive.

How Can We Help?
We’ve built decks in every part of Billings from tight city lots to sprawling properties near Zimmerman Trail. That local experience means we’re fluent in city permitting, regional load requirements, and HOA rules in areas like Ironwood and Josephine Crossing. Our process is tailored, not templated with hands-on planning, accurate quoting, and timely completion. We know what materials last, and we build with your long-term needs in mind.

Every home in Billings deserves an outdoor space that fits the way you live. Whether your backyard overlooks the Beartooths or faces a tight alley near downtown, our design team tailors every layout for your space, views, and purpose. We’ve built split-level decks in Ironwood, wraparound porches in Rehberg Ranch, and hot tub surrounds out by Laurel Road. Each project starts with listening — then ends with structure, safety, and style built to last.

The Billings climate is no joke strong UV, freezing winters, and gusty winds demand high-performance materials. We offer composite brands like Trex and TimberTech, which resist warping, fading, and moisture. Prefer natural wood? We use kiln-dried cedar and pressure-treated boards built for Montana durability. Our team will walk you through pros, cons, and lifespan — so you can choose confidently and enjoy your deck for decades.
Our process starts with a site visit and ends with your final walkthrough and we manage every step in between. That includes design, engineering, permits, and inspections. Our crews build to code and beyond, with structural reinforcements for snow loads and wind uplift. From demo to decking to post-pour concrete, we don’t cut corners. Our Billings clients love us for our communication, clean work sites, and projects finished on time.


Ironwood: A top choice for upscale homes and scenic views, Ironwood decks often feature custom railings, composite materials, and second-story layouts to take full advantage of the nearby Rimrocks.

Josephine Crossing: Known for its tight lot lines and stylish modern builds, this area demands efficient deck layouts with HOA-approved designs. We create high-functioning outdoor spaces that fit these specs.

Rehberg Ranch: With larger lots and rolling terrain, Rehberg Ranch homes are perfect for expansive multi-level decks, pergolas, and patio covers that blend with the area's rustic character.
