Materials That Handle Northwest Montana Weather

Smart Decking Choices for Kalispell’s Climate

The freeze-thaw cycles, summer sun, and heavy snowfall of Kalispell require tough, proven materials. We use composites like Trex and TimberTech, as well as cedar and pressure-treated wood — all selected for performance and longevity. Our fasteners resist rust, our posts are reinforced, and every project includes local weather considerations built in from the start.

From Permits to Final Inspection, We Handle It All

When you hire us, you get our crew not a rotating list of subs. We design your deck, pull permits, prep the site, build it out, and walk you through the finished product. Whether we’re pouring footings in the spring thaw or building a screened-in porch before snow hits, you can count on timely work, clean job sites, and structures that pass inspection the first time.
