Brooklyn's Custom Railing Shop

Brooklyn Stair Railings is a custom metal shop, and we build for the first second you grab hold. A railing is judged by how solid it feels under your hand, and a wobbly one you never really trust again. Most of the railings we get called out to fix aren't ugly, they're loose: a stoop rail that rocks a little in its masonry, an interior run that gives when you lean on it coming down the stairs with an armful of groceries. We work in wrought iron, mild steel, stainless 316, and aluminum, with cable or tempered-glass infill where the design wants it. Every piece is cut, formed, TIG- or MIG-welded, and ground smooth in our own shop, then field-measured to your stair down to the fraction of an inch. Nothing snap-together, nothing off a big-box shelf.

Brooklyn throws a lot at a railing. We've templated prewar walk-up staircases where no two treads sit at the same height, brownstone stoops where the original ironwork is worth restoring rather than ripping out, and exterior runs right beside the fire escape that have to shrug off twenty winters of freeze-thaw and road salt. On anything outdoors, the finish is where the money is well spent: hot-dip galvanizing or a baked-on powder coat is the difference between welds that bleed rust in five years and a railing your grandkids can lean on. And if you're in a co-op or a two-family, we build to code from the first cut, with 42-inch guards, balusters a 4-inch sphere can't slip through, and graspable handrails at the right height, so the board or the inspector signs off without a fight. Getting that right up front saves everyone a headache later.

Fabrication Process

SEC.02
Phase 01

Measure & design

We come out and put a tape and a level on every tread, and in these old Brooklyn stairs we almost never find one that's dead square, then sketch out the design, material, and finish with you before we quote a single dollar.

Phase 02

Fabricate & weld

The railing is cut, formed, and welded in our shop, then the welds are ground smooth.

Phase 03

Prep & finish

We prime and powder-coat or galvanize the railing in your chosen color and sheen.

Phase 04

Install & inspect

We anchor the railing into masonry or framing on site and confirm it meets code.

What Brooklyn Homeowners Say

SEC.05
★★★★★
They fabricated a new wrought-iron railing for our Park Slope stoop that matches the original next door perfectly. Welded clean, powder-coated black, rock solid. You'd think it was always there.
Gregory M. · July 2026
★★★★★
Cable railing on our Williamsburg roof deck: minimal, tight tension, and it passed inspection first try. Measured everything on site and the fit was exact.
Yuki A. · June 2026
★★★★★
Our brownstone's interior stair railing was rusted and wobbly. They restored the historic ironwork instead of ripping it out, re-welded the joints, and refinished it. Beautiful work.
Denise P. · June 2026
★★★★★
Needed handrails added to a two-family to clear a violation. They upgraded the guard height and spacing, installed graspable handrails, and it signed off. Fast and fairly priced.

Common Questions

SEC.07
Should I choose wrought iron, steel, stainless, or cable?
Forged wrought iron and mild steel are the classic choice for brownstone stoops and interiors and take a powder-coat beautifully. Stainless 316 resists corrosion for exterior and coastal-facing spots, and stainless cable or tempered glass gives a minimal, view-preserving look for modern lofts and roof decks. On a classic Brooklyn brownstone, forged iron or mild steel powder-coated satin black is hard to beat; it ages the way the building does. Save the cable and glass for a modern loft or a roof deck where you're actually protecting a view. On a 1900s stoop it usually fights the house. We'll walk through the right material for your stair and budget before anything gets cut.
What does NYC code require for a stair railing?
In general, guardrails must be about 42 inches high where there's a drop, balusters must be spaced so a 4-inch sphere can't pass through, and stairs need a graspable handrail at roughly 34–38 inches. We build every railing to meet these requirements and to pass inspection.
How long does a custom railing take?
After we measure, most residential railings take about two to three weeks to fabricate, finish, and install, depending on the design, the material, and the powder-coat schedule. Repairs and handrail add-ons are usually faster.
Can you match or restore an existing historic railing?
Yes. We fabricate replacement balusters, posts, and scrollwork to match an existing rail, and we restore landmarked brownstone ironwork by re-welding joints and replacing rusted sections rather than replacing the whole railing.
Do you do both interior and exterior railings?
We do: interior staircase and loft railings, plus exterior stoop, step, balcony, deck, and areaway railings finished with galvanizing or powder coat to handle the weather.
How much does a custom stair railing cost?
It depends on the length, the material, how much ornamental detail is in it, and the finish. A plain steel stoop railing and a full forged-iron staircase aren't in the same universe. As a rough guide from what we quote most weeks: a short exterior stoop or step railing usually runs somewhere around $1,200–$3,000; a straight interior stair run in steel with simple pickets tends to land roughly $2,500–$6,000; and an ornamental wrought-iron staircase with scrollwork and custom newel posts climbs well past that. Those are ballparks to set expectations. The real number comes after we measure on site, and we always put it in writing with no surprises.
