Built for Safety. Designed for Style.

Custom Deck Railings & Stairs in Washington

Safe, Code-Compliant, and Built to Fit Your Deck

Custom Rails and Steps for New or Existing Structures

We design and build custom railing systems and stairs for decks of every size and height. Whether you need a modern cable rail, a traditional wood handrail, or wide platform stairs, we make sure it’s secure, attractive, and 100% code-compliant. Built as part of your new deck — or added to an existing one — it’s done right the first time.

More Than Just a Barrier

Railings and Stairs That Add Function and Style

We build deck rails and stairs that don’t just meet code — they match your aesthetic. Choose horizontal lines, vertical pickets, or a custom combo of materials like wood, steel, cable, or glass. We design for the way your family uses your deck, adding safety and value without sacrificing looks.

  • Composite, wood, metal, cable, and glass options

  • Wide stair treads and multi-step landings

  • Railing systems with lighting or privacy upgrades

Framed Right, Anchored Tight

We Build for Load, Lean, and Long-Term Use

Deck railings and stairs take a beating — and need proper anchoring and structural support. We use lag-bolted posts, approved brackets, and blocking at every load point. Our stairs meet rise and run code, and all rails meet height and spacing requirements. Your system won’t just pass inspection — it’ll feel secure for years.

Planning to Upgrade Your Rails or Stairs?

Here’s What Homeowners Want to Know

Railings and stairs are the most used — and most code-sensitive — part of your deck. Here are the questions we answer most often.

Question 1: Can I replace my railings without rebuilding the whole deck?

Yes — we retrofit new rail systems on safe, existing framing every day.

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

Composite or powder-coated aluminum. Both resist weather and need minimal upkeep.

Question 3: Do stairs have to have railings?

In most cases, yes — especially for steps with more than three risers. We follow code exactly.

Question 4: Can you build wide stairs for better access?

Absolutely. We offer extra-wide stairs, multi-tiered landings, and ADA-accessible options.
