Custom Sidewalk Doors

Anyone who owns a commercial building or residence in New York City may need a custom sidewalk door to access their basement from the street side of the building. These basement access doors must be constructed of highly durable materials — they sit in the middle of heavy foot traffic patterns and must bear the weight of pedestrians, bicycles, strollers, and delivery equipment every single day.

It’s also common for basement openings in New York City buildings to be non-standard sizes — irregular dimensions that require a fully custom-fabricated door rather than an off-the-shelf solution. Steel Masters NYC specializes in exactly that. We can fabricate a sidewalk door to any size, any configuration, and any specification your opening requires — and our own crew installs it.

Why custom fabrication matters for sidewalk doors

New York City buildings are rarely uniform. Older brownstones, converted commercial spaces, and renovated properties often have basement openings that don’t conform to standard dimensions. A door that doesn’t fit perfectly creates gaps and security vulnerabilities. Every sidewalk door we build is custom-measured on site and fabricated to fit — no compromises, no gaps, no shortcuts.
