Railings and stairs are more than finishing touches — they’re critical to how your deck functions and how safe it feels. We build to exceed Oregon’s safety code, using quality materials, correct rise and run dimensions, and secure handrail connections. We also make sure every detail, from post caps to footing anchoring, is designed for longevity and daily use.
Pick the Look. We'll Handle the Details.
We offer wood, composite, aluminum, and cable railing systems — each with its own look and maintenance profile. Want open sightlines? Try cable or slim pickets. Prefer privacy or classic looks? Go with wood or composite. For stairs, we offer straight runs, wraparounds, multi-directional turns, and split-level configurations, all with reinforced framing and tread options.
Wood, Metal, Composite & Cable Rails
Custom Stair Layouts for Any Deck
All Builds Meet or Exceed Oregon Code

Every railing and stair system we build starts with proper layout and load support. Stairs are framed with exact rise/run spacing, anchored stringers, and strong treads. Railings are attached to posts set in or bolted to framing — not just surface-mounted. We use corrosion-resistant fasteners and weatherproof materials to ensure everything stays solid, safe, and attractive for years.

Better Access. Better Looks.
Stairs and railings don’t have to be plain. Whether you want sleek black rails, natural cedar handrails, or decorative balusters, we’ll help you find a style that fits your home and layout. With options for built-in lighting, custom post caps, and color-matched finishes, your access features can become one of your deck’s standout design elements — not just a necessity.
Whether it’s a new build or a railing upgrade, we handle every step — from layout and materials to code compliance and finish. We help you choose the right combination of function and form, then build it to last. With years of experience in Oregon’s terrain and weather, we ensure stairs stay secure and railings hold up season after season, no matter the elevation or layout.

We build railings and stairs that don’t just pass inspection — they become features you love to look at and feel good using.

Just real craftsmanship from top to bottom.
Code-Compliant & Architecturally Clean
Great Looks Without Losing Safety
Ideal for New Decks or Upgrades
Stairs and railings shape how you move through your outdoor space. A poorly placed stair can limit flow. A shaky railing can make the whole deck feel unsafe. That’s why we take access design seriously — choosing angles, materials, and placements that feel natural and sturdy. Whether it’s a ground-level step or a full staircase with turns, we design it to make your space work better.
Planning new railings or stair access? Here are some of the most common questions we hear — with answers based on Oregon code and materials.
Oregon code generally requires railings for decks over 30" off the ground. We still recommend them for lower decks when kids or guests use the space.
Yes. We often add wraparound, side, or back stairs to decks that need better access — even years after they were built.
