DECKING & RAILING
Composite, wood, and aluminum decking and railing systems
MONTANA DECKING & RAILING EXPERTS
A deck is one of the best investments you can make in a Montana home, extending your living space into the outdoors for grilling, entertaining, and enjoying mountain views. But Montana's climate is hard on decking: freeze-thaw cycles, heavy snow loads, intense summer UV, and wide temperature swings.
Western Building Center is the largest supplier of Trex composite decking in Northwest Montana. We stock a good, better, best lineup of Trex composite decking, from Trex Enhanced Basics and Enhanced Naturals to Trex Select and Trex Transcend, along with the Trex Hideaway hidden fastener system. For railing, we carry Fortress railing, which is tested to meet or exceed codes, and Trex Select railing.
Our team can help you compare materials, put together a materials list, and plan your project. Check with your local Western Building Center for the lengths and colors they stock. Whether you are building a small entry deck in Libby or a multi-level deck in Whitefish, we provide the products and local support to get it done right.

Composite Decking That Handles Montana Extremes
Montana decks endure a wide temperature range: sub-zero winters, 90-degree summers, and freeze-thaw cycles that stress every fastener and board. High-performance composite deck boards are engineered to eliminate the time-consuming maintenance of wood, and a protective shell gives Trex decking scratch resistance and easy soap and water cleanup.
Trex decks will not rot, warp, crack, or be devoured by termites, and Trex backs its decking and railing with a 25-year limited residential warranty, with added fade and stain coverage on its high-performance lines. Our team can walk you through the differences between Trex lines so you choose the board that fits your budget and your deck.
Railing Systems for Mountain Views
Montana homeowners build decks to enjoy mountain views, so the last thing you want is a bulky railing system blocking the scenery. Fortress railing is finished with a durable, multi-layered, anti-corrosion coating for virtually maintenance-free, long-lasting railing, and Fortress tests its products to meet or exceed codes.
Our team helps you navigate railing code requirements for your project. Ask your local store which railing colors and styles they stock.
Full Deck Project Support
Building a deck involves more than choosing boards. Footings, framing, joist spacing, flashing, fasteners, and railing all need to work together as a system. Bring your deck plans to any store, and our team can put together a materials list for the decking, railing, framing, and hardware.
For contractors, we offer competitive contractor pricing, House Accounts with 30-day terms, and scheduled, local delivery to your jobsite. The Trex Hideaway fastener works with both wood framing and metal joist systems.

FREQUENTLY ASKED QUESTIONS
What decking material is best for Montana?
Composite decking is a popular choice in Montana because it resists moisture, UV, and temperature extremes without the upkeep of wood. Western Building Center is the largest supplier of Trex composite decking in Northwest Montana, and our team can help you compare options.
How does composite decking compare to wood?
Composite decking usually costs more up front than pressure-treated wood, but it needs no sanding, staining, or painting. Trex Enhanced Basics is designed to compete directly with treated lumber decking. Ask your local store for current pricing.
Can you estimate decking materials for my project?
Yes. Bring your deck plans to any store and our team can put together a materials list for boards, framing, railing, fasteners, and hardware.
Can I see decking in person?
Yes. Visit your local store to see the decking and railing on hand, and check with the store for the lengths and colors they stock.
