Steel Casement Window Restoration in Manhattan

Metal Man Restoration restores steel casement windows for Manhattan’s prewar apartment houses, lofts, landmark buildings, and townhouses. With over a century of combined experience in steel casement work, we strip, repair, weatherproof, and refinish original steel windows so they operate and seal properly again, without losing the look that makes them worth keeping. Restoring original steel windows is almost always preferred to replacing them, especially in a landmark or prewar building.

Manhattan Steel Windows We Restore

Steel casement windows are everywhere in early-20th-century Manhattan buildings. We restore them in settings such as:

• Prewar apartment houses and co-ops on the Upper East and Upper West Sides
• Industrial and loft conversions in SoHo, Tribeca, and Chelsea
• Landmark and civic buildings with original steel windows
• Townhouses and brownstones
• Commercial storefronts and entrances

What Steel Window Restoration Involves

Old steel casements usually suffer from rust, failed paint, worn hardware, broken seals, and windows that stick or will not close. We strip the steel back to sound metal, treat and repair rust, straighten and rework the frames and operable sections, replace or restore the hardware, and refinish and weatherproof the window so it opens, closes, and seals the way it should. The result keeps the original steel profile that new replacements cannot match.

Why Restore Steel Casement Windows Instead of Replacing Them?

Original steel casement windows have slim sightlines and a character that modern aluminum or vinyl replacements cannot reproduce. In a landmark or prewar Manhattan building, replacing them can trigger board or Landmarks Preservation Commission issues, and the cost of custom replacements often rivals restoration. Restoring the originals keeps the look correct, preserves the material, and avoids those approvals.

Metal Man’s Steel and Landmark Experience

Steel casement restoration is a specialty at Metal Man, backed by over a century of combined experience. It sits alongside our broader landmark metalwork, including projects like the Alexander Hamilton U.S. Custom House in Lower Manhattan. That same care for historic metal goes into every window we restore. For related exterior metalwork, see our architectural metal restoration in Manhattan.

Neighborhoods We Serve Across Manhattan

In SoHo, Tribeca, and Chelsea, we restore steel windows in loft and industrial conversions. On the Upper East and Upper West Sides, it is prewar apartment houses and townhouses. Across Midtown and Lower Manhattan, it is commercial and landmark buildings. Wherever the windows are, we keep the original steel working and looking right.

Common Questions About Steel Window Restoration in Manhattan

These are the questions Manhattan owners, boards, and architects ask us most about steel casement windows.

Can rusted steel casement windows be saved?

In most cases, yes. We treat and repair rust, rework the frames, and refinish the steel. Windows that look beyond hope are usually restorable, which avoids the far higher cost of custom replacements.

Will restored windows open and seal properly?

Yes. We rework the operable sections and hardware and weatherproof the window so it opens, closes, and seals the way it was meant to, rather than sticking or leaking.

Is restoration allowed in a landmark building?

Restoring original steel windows is generally preferred over replacement in landmark and prewar buildings because it preserves the historic material. We can work within your building’s board or Landmarks Preservation Commission requirements.

Do you handle large commercial window projects?

Yes. We restore small to large steel casement projects for both residential and commercial buildings, and we scope the work to fit the building and its schedule.

Is restoration cheaper than replacement?

Often, yes. Custom steel replacements that match the originals are expensive, and restoration usually costs less while keeping the original material and look. We assess each building and give an honest comparison.
