Interior Stair Railings in Brooklyn, NY

Brooklyn Stair Railings designs, fabricates, and installs custom interior stair railings that fit your staircase exactly rather than a snap-together kit. Every railing is field-measured, built in our shop from forged wrought iron, mild steel, or stainless steel, and welded into one rigid assembly. We form the top rail, bottom rail, balusters, and newel posts to your run and rise, then grind every joint smooth before finishing. The result is a solid, code-compliant railing that reads as part of the house, not an afterthought.

Field-Measured, Welded to Fit

No two Brooklyn staircases are the same, so we start every interior railing with a field measurement of the run, the rise, and the exact angle of the stringer. That template drives the fabrication: we cut and form the top rail and balusters in the shop, TIG or MIG weld the assembly square, and grind the welds flush so the finished rail is seamless to the touch. Because the railing is built to your measurements rather than trimmed from a stock kit, the balusters land plumb, the rail follows the pitch cleanly, and the whole assembly anchors solid with no rattle or flex. This custom approach is what separates a fabricated railing from a big-box handrail that never quite fits the stairs it sits on.

Materials for Interior Stairs

Interior railings give you the widest choice of material because they are protected from the weather. Traditional forged wrought iron suits brownstone and pre-war interiors, with scrolls, collars, and twists worked into the pickets for an ornate look. Mild carbon steel is the workhorse for clean, modern lines and takes a durable powder-coated finish in any color. Stainless steel and horizontal cable infill read contemporary and pair well with newer condo interiors, while glass panels open up sightlines on an open-plan stair. We walk you through the trade-offs in cost, weight, and style so the railing matches both the staircase and the way the room is meant to feel.

Code-Compliant Balusters and Handrails

Interior stair railings in Brooklyn have to satisfy the same guardrail and handrail rules as any other. Where there is a drop, the guardrail runs roughly 42 inches high, and the balusters are spaced so a 4-inch sphere cannot pass between them, which rules out the wide gaps common on older stairs. A graspable handrail is set at the 34 to 38 inch range so it is comfortable and continuous along the flight. We build these dimensions into the fabrication from the first measurement so the finished railing is safe underfoot and passes inspection without rework.

Frequently Asked

Are your interior stair railings custom-made or a kit?
They are custom fabricated. We field-measure your staircase, cut and form the steel or iron in our Brooklyn shop, and weld the railing into one solid assembly built to your exact run and rise. We do not install snap-together big-box kits, which never fit an older staircase cleanly.
How far apart can the balusters be?
Code requires that a 4-inch sphere cannot pass between the balusters, so no gap exceeds 4 inches. We space the pickets to meet that rule from the start, which is a common failure point on older Brooklyn railings that were built before the current spacing standard.
What material is best for an interior railing?
It depends on the look. Forged wrought iron suits brownstone and pre-war interiors, mild steel gives clean modern lines and takes powder coating well, and stainless steel with cable or glass reads contemporary. We help you weigh cost, style, and maintenance before we fabricate.
How high does an interior stair railing have to be?
The guardrail runs about 42 inches high where there is a drop, and the graspable handrail sits in the 34 to 38 inch range. We build both dimensions into the railing during fabrication so the finished assembly is comfortable and inspection-ready.
