Every property in Kalispell has its own character from narrow city lots to wide open spaces near Lone Pine State Park. We tailor each deck to your home’s elevation, sightlines, and use case. Want a hot tub surround with privacy? A covered deck with lighting and fans? A grilling area with a view of Flathead Lake? We design it all with structural integrity and year-round Montana use in mind.
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.
Full-Service Construction No Subcontractors, No Surprises
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.
Serving Homes Across Kalispell’s Most Popular Areas
East Side: With older homes and historic character, East Side projects often involve porch restoration, re-decking, or additions that blend into classic architecture.
West Valley: Known for larger lots and rural properties, this area is ideal for expansive decks, pergolas, and hot tub surrounds that take in the mountain backdrop.
Creekside: A newer neighborhood where HOA-approved materials and efficient layouts are key — we design for privacy, flow, and long-term function.
Don't worry, we can help!
