The Flathead Valley's Only TrexPro® Platinum Builder

Decks Built for Montana. By a Montanan.

Veteran-owned, born and raised in the Flathead Valley. We engineer composite and wood decks for this climate and this ground — built to outlast the home they're attached to.

  • Veteran-Owned & Operated
  • Licensed & Insured in Montana
  • 4-Year Trex-Backed Labor Warranty
  • Financing Available
Built to Last, Built to Perform

Here in Montana, anyone can pay $125 and call themselves a contractor.

No experience required. No testing. Just a hammer and a business card. That's why the Flathead Valley is full of decks that look fine on day one — and start waving, warping, and shifting by year three.

We do it differently. Footings below the frost line. Joist protection on every build. Framing that matches the decking system's exact specs, so your warranty actually holds. That's not just carpentry — it's engineering.

We're not the cheapest bid you'll get. We're the one that's still standing — and still looking good — twenty years from now.

TrexPro® Platinum

The Only TrexPro Platinum Builder in the Flathead Valley

There's no other Platinum-level Trex installer within 135 miles. That matters for one simple reason: most composite decks around here are framed wrong — and wrong framing voids the Trex warranty. The boards start to wave and warp within the first one to three years, and the homeowner finds out their "warranty" never applied.

  • Framing built to Trex's exact spec — which changes by product line. We build to it, every time.
  • 4-year labor warranty backed by Trex itself. If anything fails in the first four years, Trex covers materials and labor — a protection only Platinum installers can offer.
  • We register your warranty for you. Most contractors never do. You get your Trex welcome package within days of completion — proof it's active.

A True Story From Right Here in the Valley

The $31,000 Deck That Didn't Last a Year

Not long ago, we tore down a deck a homeowner had paid $31,000 for. It was less than a year old. Structurally dangerous. Water damage everywhere. The foundation was already shifting.

The footings were barely a foot deep — in a climate where they need to be at least three feet down to get below the frost line. It was built with soft pine that warps like crazy here. And it was fastened with nothing but screws, which have almost zero shear strength.

The contractor wasn't evil. He just didn't know this climate or how to build for structural stability in it. That's the difference between hiring a guy with a hammer and hiring a builder who grew up watching what Montana does to structures.

The Man Behind the Name

Local. Veteran. Father. Builder.

Josiah Walker was born and raised right here in the Flathead Valley. He's a military veteran, a husband, and a dad raising his kids in the same valley he grew up in — which means every deck he builds is for a neighbor, not a customer number.

"As a veteran, I was trained to do things right the first time. No shortcuts. No excuses." That's not a slogan. It's why he'd rather lose a bid than cut a corner, and why he stops by every job site multiple times a week to check the work personally.

Straight Answers

Questions Homeowners Ask Us

How much does a new deck cost in the Flathead Valley?

It depends on size, materials, site conditions, and design — but we'll be straight with you: most of our composite builds land in the $40K–$50K+ range, and we're upfront about numbers from the first conversation. See our full composite deck cost guide for real ranges and what drives them.

Are you licensed and insured?

Yes — fully licensed and insured in Montana, and we'll gladly show proof. We'd actually encourage you to ask every contractor for it. In Montana, registration costs $125 and requires no testing, so the paper alone doesn't tell you much — the work does.

What makes a TrexPro Platinum builder different?

Platinum is Trex's highest installer tier. It means our framing meets Trex's spec (which protects your material warranty), and Trex itself backs our labor with an additional 4-year warranty — materials and labor. We're the only Platinum builder in the Flathead Valley.

Do you offer financing?

Yes, financing is available. Bring it up on the first call and we'll walk you through the options.
