Custom Deck Railings & Stairs in Montana

More Than Just Steps and Guardrails

How We Build Railings and Stairs

That Last

Every stair and railing we build starts with safety and ends with a clean, durable finish. We install railings that meet Montana code for height and spacing, with options like wood, composite, cable, or powder-coated steel. Our stairs are framed for strength, sloped for comfort, and finished to fit your deck. Whether you need a wraparound staircase or a sleek railing for a mountain-view deck, we make sure it fits, flows, and holds up.

Safe, Stylish Access for Every Deck

Where Railings and Stairs Make the Difference

The right railing or stair setup changes how your deck looks—and how you use it. Whether you need a full wrap for elevated decks or a single stair run to a patio, we design with flow, safety, and looks in mind. Our team builds straight, curved, or multi-directional stairs and installs handrails that blend seamlessly with your home’s architecture and materials.

  • Multi-level stair runs with landing platforms

  • Horizontal cable, metal, or composite railings

  • Railing height and spacing built to Montana code

Options for Wood, Metal, Composite & Combinations

Custom Materials That Match and Perform

We offer stair treads and railings in cedar, pressure-treated pine, composite decking, powder-coated aluminum, and hybrid styles. Wood offers warmth and natural texture; composite adds durability and low maintenance. For railings, we offer modern cable, vertical pickets, glass inserts, or mixed-material designs. Every component is finished to resist sun, snow, and foot traffic.

Framed, Anchored, and Built to Code

Why Our Stairs and Railings Outlast the Rest

Deck stairs take a beating especially in Montana where freeze-thaw cycles and heavy snow can shift or split poorly built frames. We reinforce every tread, anchor every post, and ensure every railing line meets code. We don’t skip steps. From galvanized fasteners to rot-resistant framing, we build railings and stairs that stay level, safe, and solid for years.

Your Deck, Your Style Without Sacrificing Safety

Designed for Code, Customized for You

Our railings and stairs don’t come in a box they come from experience. We build to meet or exceed IRC and Montana residential deck code, and we design with your preferences in mind. Want minimalist cable lines with wide cedar treads? Or classic picket railing with closed risers? We’ll make it work, measure it right, and build it clean.

Every Step, Every Railing Made for Montana

We’ve built stairs for two-step entries and multi-flight decks with wraparound views. Our railings range from clean-lined metal to rustic wood with horizontal accents. Whatever your deck setup, we’ll make it safer and more usable with high-quality, weather-tough craftsmanship you’ll notice on every step.

  • Great for high decks, walkouts, and elevated landings

  • Works with composite, wood, and hybrid decking

  • Optional lighting, grip rail, or ADA handrail add-ons

Montana Code. Montana Snow. Montana Craftsmanship.

Deck Stairs and Railings That Handle the Elements

We build for Montana not mild climates. That means stronger brackets, deeper posts, proper rise and run, and fasteners that don’t rust when buried in snow. Every stair set includes drainage planning, and every railing is anchored, sealed, and aligned with laser precision. Whether in wind-heavy Helena or snow-packed Kalispell, our work stands up year after year.

What to Know Before Replacing Stairs or Railings

Montana Railing & Stair FAQs

Here are answers to the most common questions we hear from Montana homeowners about railing upgrades and stair installs:

Can you replace just the stairs or railing?

Yes. We inspect the structure and can replace either component independently—while checking for code and safety issues.

What railing types are best for snow?

Metal and composite perform best, but we seal cedar and treated wood to last in all seasons.

How high can my deck be without a railing?

Most decks above 30 inches from grade require railings per Montana residential code.

Can you add lighting or grip rails to my stairs?

Absolutely. We offer tread lights, ADA-compliant rails, and night-friendly designs.
