Railings and stairs do more than look good—they keep people safe and help your deck work better. We build to Wisconsin safety codes, ensuring proper rail height, baluster spacing, and stair rise/run ratios. Every project starts with an on-site layout to ensure visibility, clearance, and strength. From low-profile side steps to grand staircases, we build with purpose and precision.
Choose from wood, composite, vinyl, metal, or cable for your railing system—each with unique looks and maintenance levels. For stairs, we build straight, wraparound, or multi-directional runs with solid risers and framed stringers. We also offer ADA-compliant handrails, low-voltage lighting, and code-required landings where needed. It’s safety built to last—and look good doing it.

We build rail systems that enhance your space, not distract from it. Want sleek black metal spindles with cedar rails? Composite posts with cable infill? Classic wood with decorative balusters? We help you choose the right mix of materials and styles to match your home, meet safety codes, and keep maintenance simple. Every component is rated for outdoor use and secured with precision.

No more wobbly steps or uneven treads. We build stairs that feel stable, look clean, and hold up to constant use. Whether you want a straight run, wraparound steps, or platform landings, we design each layout with ideal tread depth, consistent rise, and slip-resistant finishes. Stairs can also include built-in lighting, wider treads, or integrated handrails for better access.
Outdoor stairs and railings need to do more than look good on install day—they need to stay strong through rain, snow, and sun. We use pressure-treated or composite stair framing, rust-resistant fasteners, and sealed materials to prevent rot, warping, and loosening over time. We also follow every local code to make sure your project passes inspection and performs for decades.

Don't worry, we can help!
Every stairs and railing project starts with a walk-through and design consult. We take measurements, review access points, and discuss your style and safety goals.
