Whether you need wide, comfortable stairs or railings that meet code without looking industrial, we build systems that blend safety with great design. From rustic wood to modern cable or composite railings, every project is custom fit and installed to last. Our work meets Wyoming’s deck height and safety standards — and looks good doing it.
Deck stairs need the right rise, run, and support. Railings need strength, spacing, and secure attachment. We handle every cut, bracket, and anchor to ensure your deck stays safe and comfortable — no matter the weather or traffic. Our materials include cedar, composite, powder-coated metal, cable, and vinyl, so you can choose the style that fits your space.

Custom stair treads, landings, and wraparounds
Built to meet all residential deck code requirements

Railings frame your view, and stairs shape how you move between your home and yard. That’s why we design both for comfort, flow, and appearance — not just code compliance. Whether you want a clean horizontal profile, a craftsman-style look, or open risers with under-lighting, we help you choose options that match your home and how you live outdoors.

From icy steps to dry heat and high winds, your railings and stairs need to handle more than foot traffic. We use pressure-treated framing, sealed fasteners, and weather-rated materials designed to stay safe and strong through every season. Whether we’re replacing old stairs or adding new rails to an existing deck, you’ll get a system built to hold up — and look sharp doing it.
We build for every type of deck — whether it’s three steps to a patio or a second-story platform with a long descent. Our team designs stairs that feel stable, look clean, and offer proper landings, turns, or wraparounds based on your space. Railings are sized to meet height requirements and include secure handrails, smooth transitions, and child-safe baluster spacing.

Here’s what homeowners ask before upgrading their deck stairs or installing new railings in Wyoming.
If only a section is loose or rotted, we can replace that portion. But if the system is outdated or not up to code, full replacement is often safer and more cost-effective.
Most decks over 30 inches off the ground require a 36" or 42" high railing, depending on local code. We build to meet or exceed all state requirements.
Yes. We regularly build hybrid systems that combine different materials for style and function — such as wood framing with modern cable or composite panels.
Landings are required when stairs exceed certain lengths or turn directions. We include all necessary landings and riser configurations in our designs.
