Improve Safety, Access, and Style—One Step at a Time

Custom Deck Railings & Stairs in Wisconsin

Not Just Add-Ons—Essential Elements

Safe, Smart Railing and Stair Systems Built Right

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.

Strong Materials. Clean Finishes. Long-Term Durability.

Custom-Built Rail and Stair Options for Every Deck

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.

Safe Doesn’t Have to Mean Boring

Railings That Match Your Deck—and Your Style

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.

Stairs That Feel Solid and Look Sharp

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.

Built for Wisconsin’s Weather and Building Codes

Framed, Fastened, and Sealed for Long-Term Use

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.

FAQs About Deck Railings & Stairs

What Wisconsin Property Owners Ask Before Upgrading

Here are the most common questions homeowners ask when planning new or replacement stairs and railings.

Question 1: Can you replace just the stairs or railing?

Yes. We can retrofit new stairs or railings onto your existing deck if the structure is sound.

Question 2: What’s the best railing material for low maintenance?

Composite, metal, and vinyl railings require the least upkeep and last the longest in wet climates.

Question 3: Are permits needed for stairs or railing work?

Sometimes. If we’re altering structure or layout, yes—but we’ll handle all permitting if needed.

Question 4: Can you add lighting or handrails to existing stairs?

Absolutely. We upgrade existing stairs with lighting, railings, landings, and safety enhancements.
