Composite & Trex® Deck Builder in Kalispell & the Flathead Valley
Composite is what we're known for. Framed to Trex's exact spec, footed below the frost line, and backed by a 4-year labor warranty from Trex itself — not just from us.
A Deck You Never Have to Babysit
Montana is brutal on wood. Snow sits on it all winter, June rain soaks it, and July sun cooks it. Wood decks here need re-staining every couple of years and still splinter, crack, and gray out.
Composite doesn't ask for any of that. No staining, no sealing, no splinters under bare feet. Modern Trex boards carry up to a 50-year material warranty — if they're installed on framing that meets spec.
That last part is the catch, and it's the reason we're sticklers about what happens under your deck boards. The prettiest decking in the world fails if the structure beneath it was built wrong.
What You Get From the Valley's Only TrexPro Platinum Builder
Framing Built to Trex Spec
Trex's framing requirements change by product line. Build outside them and the boards wave and warp within one to three years — and the warranty is void. We build to the spec, every line, every time.
4-Year Labor Warranty From Trex
Trex backs Platinum installers with an additional 4-year warranty covering materials and labor. If anything fails in the first four years, Trex makes it right. No other builder in the valley can offer that.
Your Warranty, Actually Registered
Most contractors never register the warranty. We activate yours through the TrexPro portal, and Trex mails you a welcome package within 2–3 days — written proof your coverage is live.
The Parts of Your Deck You'll Never See
- Footings at least 3 feet deep — below the Flathead Valley frost line, so frost heave can't shift your foundation.
- Joist protection tape on the framing — keeping water out of the structure so it outlasts the boards on top of it.
- Hidden fasteners — clean board faces, no popped screw heads, and proper gapping for expansion.
- Structural hardware, not just screws — joist hangers and connectors with real shear strength, rated for snow load.
- Picture-frame borders and clean detail work — because the visible craftsmanship should match what's underneath.

What a Composite Deck Costs Here
We won't pretend composite is cheap, because it isn't. Materials alone on a quality build often run $20,000 or more, and most of our composite projects land in the $40K–$50K+ range depending on size, site, railing, and design. Larger outdoor living projects can go well beyond that.
What we will promise: honest numbers from the first conversation, a detailed line-item proposal, and no surprise change orders. Financing is available if you'd rather spread it out.

Is Trex worth it compared to a wood deck?
For most homeowners here, yes. It costs more upfront, but it never needs staining, won't rot or splinter, and handles our freeze-thaw cycles far better than soft lumber. Think of it this way: people spend $80K on a truck that loses half its value the day they drive it off the lot. A composite deck builds family memories, lasts longer than you'll keep that truck, and adds value to your home. Full comparison: Composite vs. Wood in Montana.
What does TrexPro Platinum actually mean?
It's Trex's highest installer tier. We're the only Platinum builder in the Flathead Valley — no other one within 135 miles. Your framing meets Trex's spec (keeping the material warranty valid), and Trex backs our labor for 4 years on top of it.
Why do composite decks around here warp?
Bad framing, almost every time. Trex's framing requirements vary by product line, and when a contractor ignores them the boards start waving within one to three years — with the warranty voided by the install itself. Honestly, almost none of the existing Trex decks we inspect in the valley were built right.
Do you register the Trex warranty for me?
Yes — we activate it through the TrexPro portal when the job wraps, and Trex sends you a welcome package within 2–3 days confirming your coverage is live. Most contractors skip this step entirely. More here: The Trex Warranty Most Homeowners Never Actually Get.
