Every Step Counts — Make Them Safe and Stylish

Custom Deck Railings & Stairs in South Carolina

Form, Function & Full Compliance

Why Quality Railings and Stairs Matter

Stairs and railings aren’t just extras — they’re safety features that need to be built right. We construct stairs with the correct rise and run, use code-approved rail spacing, and anchor everything to structural framing. Our railings come in wood, metal, composite, or cable — and we can match or contrast them to your deck for a seamless or standout look.

Crafted for Safety. Styled for You.

What’s Included in Our Stair & Railing Projects

We build stairs that feel solid, look clean, and fit your yard’s grade. Railings can be traditional, modern, or completely custom — including top caps, post wraps, and lighting add-ons. Whether it’s a small set of steps or a full multi-tier stair layout with landings, we handle design, code compliance, and clean installation every time.

Built to Step Up — and Hold Up

Deck Stairs That Are Solid, Safe & Smooth

We build stairs that feel sturdy underfoot and look great from every angle. Each step is cut and set to the right height for comfort and code. We match stringers and treads to your deck surface — composite, wood, or capped PVC — and offer riser wraps, fascia trim, and landing platforms when needed. Whether your stairs are straight, wraparound, or multi-directional, they’ll work beautifully for years.

Railings That Add More Than Just Safety

Design-Driven Rail Options for Every Style

Railings can blend in — or stand out. We offer wood, aluminum, steel cable, or composite rail systems that meet code and match your home’s look. Add decorative post caps, low-voltage lighting, or contrasting top rails for more personality and better nighttime safety. All hardware is concealed or color-matched for a polished finish.

Multi-Level? No Problem.

Custom Rail & Stair Layouts for Elevated Decks

If your deck is more than a few feet off the ground, code requires railings and stairs built to exact specs. We handle everything from tall stair runs and switchback steps to level transitions and multi-deck connections. We design layouts that keep your deck legal, accessible, and beautiful — no matter how complex the grade.

Rail & Stair FAQs

Common Questions From South Carolina Homeowners

Here are the answers to popular questions about custom railings and deck stairs across South Carolina.

Q1: Are railings required on my deck?

If your deck is more than 30 inches above grade, code requires railings — and we build to meet every local standard.

Q2: What’s the best railing material?

It depends on your needs. Wood is classic. Composite is low-maintenance. Cable is modern and view-friendly. We’ll help you choose.

Q3: Can I add lighting to my stairs or rail posts?

Yes. We install low-voltage lighting into post caps, risers, or under-rail channels for added safety and style.

Q4: Do stairs need a landing?

Sometimes — especially if the run exceeds code limits. We’ll design landings, turns, or switchbacks when required.
