Decks in Missoula must manage more than just looks they need to handle freeze-thaw cycles, UV exposure, hillside erosion, and occasional wildfire ash. That’s why we reinforce every structure for the elements. We build with composite or sealed cedar, frost-rated footings, and corrosion-resistant hardware. Whether it’s a covered grilling station or a second-story retreat, we build strong, stylish, and code-compliant decks that last.

How Can We Help?
From slope-side homes in Grant Creek to historic porches in the University area, we’ve built decks across Missoula’s unique terrain and architectural styles. We know the codes, HOA rules, and real-world challenges and we build around them. With in-house crews, clear timelines, and no cut corners, we deliver every time.

In Missoula, decks aren’t just a nice addition they’re an extension of how you live. We design decks that fit your property and needs, whether it’s an elevated view deck in Miller Creek or a shaded porch in the sloped University District. Want built-in seating, a grilling station, or a covered retreat? We make it happen with materials and layouts that handle wind, weight, and weather.

With UV intensity, cold snaps, and big snow loads, Missoula decks need more than generic materials. We use Trex and TimberTech composites for fade-resistant performance, and cedar or pressure-treated lumber for a more natural look. From post brackets to joists, we use hardware that’s corrosion-rated and built to perform through Montana’s wild weather swings.
You don’t have to worry about paperwork or permits we’ve got that covered. Our team manages the entire process, from design and materials to final inspection. Whether you’re in the city limits or out past Blue Mountain Road, we follow Missoula’s zoning, HOA, and code requirements with zero surprises. Clean job sites, timely progress, and rock-solid builds are part of every project.


University District: Older homes and classic porches define this area. We specialize in matching materials and styles while upgrading safety and structural integrity.

Miller Creek: Known for expansive views and sloped lots, this area is ideal for multi-tiered decks, patio covers, and hot tub surrounds.

Grant Creek: With tree-lined streets and custom homes, decks here need thoughtful design and top-tier materials to match architecture and protect from shade moisture.

Montana weather doesn’t take it easy on decks. From sun-bleached boards to frost-warped footings, we repair or replace what’s needed and keep what’s solid. If your frame is sound, we’ll re-deck with low-maintenance composite or beautiful new cedar. If it’s not, we’ll rebuild from scratch with upgraded support. We also restore older porches especially in historic neighborhoods where looks and safety matter.
