Havre sees it all, wind, snow, intense sun, and dry stretches. Your deck needs to be ready for those extremes. We build using pressure-treated framing, weather-rated fasteners, and decking materials that won’t crack, fade, or warp. Whether you live near MSU-Northern or out past the city limits, our structures are made to withstand Havre’s harsh elements and heavy use.

Every home in Havre is unique and your outdoor space should be, too. We design decks that complement your property, whether it’s a mid-century ranch in Highland Park or a new build near 13th Street. Want a covered grilling area? A second-story platform with Hi-Line views? A kid-safe rail system or ADA ramp? We make it happen with form, function, and regional durability in mind.

In Havre, your deck faces months of wind, dry air, and blazing sun — followed by freezing winters. That’s why we use proven materials like Trex and TimberTech composite, along with high-quality cedar and pressure-treated boards. All our projects include rust-resistant fasteners and proper sealing to ensure longevity. We help you choose the right combination based on use, exposure, and upkeep preferences.
You don’t need to juggle contractors or worry about code compliance. We handle the entire process layout design, materials, permitting with the City of Havre, buildout, and inspections. Whether it’s a new deck, a screened-in porch, or a structural overhaul, we manage every detail with efficiency and respect for your time and property. It’s how we’ve earned trust across the Hi-Line.


Highland Park: A well-established neighborhood with mature trees and older homes, Highland Park is ideal for porch restorations, custom railings, and decks that blend into existing architecture.

Bullhook Bottoms: This area often requires elevated or slope-aware decks to manage floodplain concerns. We design structures for stability, drainage, and great views.

East End: Known for tight lot sizes, East End properties benefit from compact deck designs and efficient use of backyard space. We specialize in maximizing function without crowding.
