Safety, Style & Code Compliance in Every Step

Custom Deck Railings & Stairs in Pennsylvania

Add Safety and Visual Appeal to Your Deck

Handrails, Balusters, and Stairs That Work With Your Layout

Railings and stairs do more than provide access—they tie your whole deck together. At Alliance Deck Builders of Pennsylvania, we build custom railing systems and staircases that match your materials, comply with local codes, and stand up to years of use. From clean-lined cable rail to traditional wood, we build it right—secure, level, and ready for daily traffic.

Railings That Match Your Deck’s Style and Safety Needs

Choose From Composite, Wood, Cable, or Metal

We install railings that do more than meet code—they enhance your deck’s design. Go sleek with horizontal cable or aluminum, classic with wood pickets, or low-maintenance with composite and vinyl. Every system is secured to framing and finished for long-term durability. We’ll help you pick the right material based on your layout, exposure, and maintenance goals.

Custom Steps Built for Safety, Durability & Code

Whether you need a single step to your patio or a full staircase from an elevated deck, we build stairs that are safe, sturdy, and code-compliant. We handle riser spacing, tread depth, and landing size to ensure smooth access and a comfortable feel underfoot. All stair systems are anchored properly and designed to complement your deck materials and trim.

Durable, Low-Maintenance Materials That Stay Safe Over Time

No Warping, Splitting, or Wobble—Just Solid Craftsmanship

We use weather-resistant materials and proven fastening systems to ensure railings and stairs stay solid through freeze-thaw cycles and daily use. Composite and aluminum options won’t rot or rust, while sealed wood stays straight with proper finishing. And everything we install is anchored securely to your framing—no wiggle, no looseness, just long-term stability.

Clean Installations That Upgrade Appearance and Access

Finished Touches That Make a Real Difference

Railings and stairs are often the first thing people touch on your deck—and the last thing you want failing. We take extra care to get spacing, mounting, and finish details right. That means consistent picket gaps, smooth transitions, and fasteners that don’t show. We also offer post caps, integrated lighting, and trim upgrades to make each system stand out.

What to Expect From a Railing or Stair Build

We start by assessing your deck elevation, style, and code requirements. Then we design the right stair run or railing layout, using materials you choose. Once approved, we install cleanly—cutting no corners, drilling no shortcuts, and finishing every piece for comfort and durability. You’ll get smooth, stable upgrades that look and feel just right.

Railings & Stairs That Work With Your Layout

No matter your deck height or shape, we design railing and stair systems that fit perfectly. Need a landing for a long run? Angled steps for a slope? Gate access or ADA-compliant rails? We’ll plan it out before the first cut. Every piece is tied into your deck framing to avoid shifting or stress. We don’t just build to code—we build to how you use your deck every day.
