Wood decks remain one of the most requested options across Montana—and for good reason. Cedar offers natural resistance to decay and insects, with warm tones and grain that elevate any home. Pressure-treated lumber is strong, affordable, and can be stained or sealed to match your style. We install both with precision, spacing boards for airflow and securing every joint for long-term stability. Whether you're in snowy Butte or sunny Belgrade, we tailor your deck to your environment and budget.
Wood decking remains a top choice for its natural beauty, warmth, and versatility. With proper installation and regular care, cedar and pressure-treated decks can last 15–25 years. They’re also easy to repair, stain, and modify—making them perfect for homeowners who want design flexibility over time. Whether you prefer the scent of cedar or the strength of treated lumber, we build decks that blend seamlessly with your home and Montana’s natural surroundings.

Building wood decks in Montana means thinking beyond square footage. We account for snow loads in Helena, freeze-thaw cycles in Great Falls, and UV exposure in Whitefish. Our crews frame with treated lumber, anchor to code, and use techniques proven to reduce warping, cupping, and board lift. From simple landings to wraparound retreats, we deliver true craftsmanship and structural integrity—every board, every beam, every time.

Not sure which wood is best? We walk you through every option. Cedar offers a rich color, aromatic scent, and natural resistance to pests—great for high-end looks and smoother finishes. Pressure-treated wood costs less upfront and holds up to soil contact, making it ideal for support framing or large builds on a budget. We use grade-specific lumber based on use—framing, decking, or railing to deliver both beauty and structural strength where you need it most.
We don’t cut corners—literally or figuratively. From soil prep and footings to fascia and sealing, we handle every detail. Need demo of an old structure? We’ll clear it and recycle where possible. Want help choosing stain or finish? We’ve got color samples and expert tips. Whether it’s a new build or expansion, we build clean, accurate, code-compliant decks that are ready for Montana’s toughest seasons.
