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 demand materials that go beyond what works in milder climates.
Western Building Center carries decking and railing systems from the brands that perform best in our conditions. Our 12 stores stock composite decking, PVC decking, pressure-treated lumber, aluminum railing, composite railing, and all the fasteners, framing hardware, and accessories you need for a complete deck build.
Our decking experts help you compare materials, estimate quantities, and plan your project from footings to finish caps. We know which products hold up best at Montana elevations, which colors fade the least, and which railing systems meet code while looking great. Whether you're building a small entry deck in Libby or a multi-level entertainment deck in Whitefish, we provide the products and project support to get it done right.

Composite Decking That Handles Montana Extremes
Montana decks endure a wider temperature range than almost anywhere in the lower 48 — sub-zero winters, 90-degree summers, freeze-thaw cycles that stress every fastener and board. Composite decking from TimberTech and Trex is engineered to handle this punishment without the cracking, warping, and splintering that plague wood decks after just a few Montana seasons.
Our decking specialists help you compare composite products side by side with full-size samples in every store. We explain the differences between capped composite, capped polymer, and PVC boards so you choose the material that matches your budget, your aesthetic, and the specific exposure conditions at your home.
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. Aluminum and cable railing systems offer clean sight lines with the structural strength Montana building codes require. We carry powder-coated aluminum railing in multiple colors that complement any deck design.
Our team helps you navigate railing code requirements including post spacing, graspable handrail profiles, and baluster spacing for child safety. We stock complete railing kits and components for DIY installation, and can recommend local contractors for professional installation.
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. Our team provides material estimation from your deck dimensions or plans, including substructure framing, decking, railing, stairs, and every fastener and accessory needed to complete the build.
For contractors, our project coordination includes staged deliveries to match your build schedule, volume pricing across all materials, and dedicated support from our contractor desk. We stock the joist tape, hidden fastener systems, and structural hardware that professional deck builders require.

FREQUENTLY ASKED QUESTIONS
What decking material is best for Montana?
Composite and PVC decking from TimberTech and Trex are the most popular choices in Montana. They resist moisture, UV, and temperature extremes without the maintenance of wood. Our team helps you compare options.
How much does composite decking cost compared to wood?
Composite decking costs more upfront than pressure-treated wood, but requires no staining, sealing, or replacement over its 25-50 year lifespan. Over time, composite is typically the better value in Montana.
Can you estimate decking materials for my project?
Yes. Bring your deck dimensions or plans to any store. We calculate boards, framing, railing, fasteners, and hardware quantities.
Do you have decking samples I can see?
Every store has full-size decking and railing samples in multiple colors and profiles. We also have display boards showing different railing and decking combinations.
What railing system do you recommend?
Aluminum railing offers the best combination of durability, low maintenance, and clean sight lines. Composite railing matches your deck color but is bulkier. Cable railing is popular for view properties. Our team helps you choose.
Do you deliver decking materials?
Yes. We deliver decking boards, framing lumber, railing systems, and accessories directly to your home or jobsite from any of our 12 locations.
