RAILINGS BUILT
TO FIT YOUR HOME

A railing is one of the most visible, most touched, and most frequently photographed elements in a home. It needs to be beautiful, structurally sound, precisely fitted, and durable enough to look the same twenty years from now. That's a high bar — and it's the standard we build to.

Every railing we fabricate is built to your exact measurements — not cut down from a stock panel, not assembled from off-the-shelf components. We measure your space, design for the opening, and weld each component to fit. The result shows.

We work on everything from single-flight stair railings for a renovation project to full-home railing systems on new construction. Interior or exterior, historic restoration or modern new build — we've done them all throughout Boulder County.

WHAT THEY SAY

★★★★★

"We hired Oak & Iron for our stair railing and the difference from what we had before is night and day. The fit is perfect — not a single gap where you'd expect one. The welds are clean enough to look decorative. The powder coat is flawless. We've since recommended them to three neighbors and will absolutely use them again for our deck."
