Cable Railing in Greenville, SC — Interior Stairs & Decks
Cable railing turns a staircase or deck into a clean, modern focal point — thin stainless lines that hold the view instead of blocking it. CSR Stair designs, fabricates, and installs custom stainless steel cable railing for homes across Greenville and the Upstate. As a second-generation stair company, we handle the part most contractors get wrong: cable runs that stay tight, posts that stay rigid, and a finished system that passes code and still looks effortless.

Interior Cable Railing for Staircases
A cable railing on an interior staircase is one of the highest-impact upgrades in a home. It floods stairwells with light, makes small spaces feel larger, and pairs beautifully with stained wood treads and open risers. We specialize in interior cable systems — wood or metal posts, horizontal stainless runs, and a hardwood or metal top rail sized to your home. This is the look most Greenville builders don't offer in-house; we do.
Exterior & Deck Cable Railing
Outside, cable railing keeps the view to your yard, treeline, or pool wide open while meeting deck-railing code. We use marine-grade stainless hardware built to handle Upstate humidity without rust streaks or sag.
Materials We Use
- 316 marine-grade stainless cable & fittings — resists corrosion outdoors and stays bright indoors. (Cheaper 304 hardware is where bargain installs fail.)
- Posts: stained hardwood, powder-coated steel, or stainless — matched to your stairs or deck.
- Top rails: custom wood (oak, maple, walnut) or metal.
Every system is fabricated to your measurements — never cut from a one-size kit.
Cable vs. Glass vs. Iron — Which Is Right for You?
Cable gives a nearly unobstructed view with a modern, minimal look and low upkeep — ideal for stairs and decks where you want light and openness. Glass is sleek but shows smudges and needs frequent cleaning. Iron balusters suit traditional homes and partially block the view. Not sure? That's what the free consultation is for — we'll show you samples in your space.
Code & Safety — the Part That Protects You
Cable railing has specific code requirements, and a system that ignores them fails inspection. We build to them as standard:
- 4-inch sphere rule — cables spaced so a 4″ ball can't pass between them.
- Proper cable tension & intermediate posts to prevent deflection (sagging or spreading) over long runs.
- Correct guard height for residential stairs and decks.
Knowing this cold is what separates a stair specialist from a handyman — and it's why your install passes the first time.
Our Process
- Free in-home consultation & measurements.
- Design & written quote — layout, materials, and a clear price.
- Custom fabrication — built to your measurements.
- Clean, on-time installation — tensioned, finished, inspection-ready.
What Cable Railing Costs
Most cable railing projects are priced by linear foot and depend on total length, number of corners and posts, post material, interior vs. exterior, and your top-rail choice. We give every customer a clear, written, itemized quote — no vague "starting at" pricing. Call (864) 349-6901 for a free estimate.

Cable Railing FAQ
Is cable railing safe for homes with kids?
Yes — when built to the 4″ sphere code with proper tension, it's as safe as any guardrail. Loose, bargain-kit cable is the only unsafe version, and correct tensioning prevents exactly that.
Does cable railing sag over time?
Not when it's engineered right. We use intermediate posts and correct tension so runs stay taut for years.
Can you put cable railing on existing stairs?
Usually yes — we retrofit cable systems onto many existing staircases and decks after assessing the framing.
How long does installation take?
Most residential projects take 1–3 days after fabrication, depending on length.
