Repairing Philadelphia's Steel Windows

Heritage Steel Window Repair is a small, specialized team of steel window technicians, glaziers and carpenters based in Port Richmond, Philadelphia.

Philadelphia and its suburbs are full of steel windows: in rowhouses and twins from the 1920s to the 1950s, in stone Colonial Revival homes on the Main Line, in churches, schools and former factories. Many of them are being torn out when they only need repair. We started this company to offer the alternative.

We repair and restore steel, bronze and wood windows, steel doors, storm windows and hardware, and we install new steel windows where originals are lost. Our shop handles stripping, welding and joinery; our field crew handles adjustments, glazing and installation. Most projects are run start to finish by the same people.

Founder: Michael Kowalski

Our History

Founded in 2008 by a steel fabricator who kept getting asked to fix old windows. Today steel and historic windows are all we do.

Our Mission

Keep good original windows in service. Repair what can be repaired, and replace only what truly cannot be saved.

Our Approach

Clear written scopes, lead-safe work, clean job sites and windows that open, close and seal when we leave.

how we work

Our Restoration Process

The same four steps on every project, from a single window to a whole building.

Survey

Every window numbered, photographed and checked.

Shop Work

Stripping, welding and joinery at our Port Richmond shop.

Glazing and Paint step of a steel window restoration

Glazing & Paint

New glass, putty and a rust-inhibiting paint system.

Final Check

Every vent opens, closes and latches before we leave.

Our 1930s steel casements had not opened in years. The crew freed every one of them, replaced the broken glass and the house is noticeably less drafty this winter.

They gave us a clear window-by-window estimate and stuck to it. The restored windows look original, which was exactly what our historic district review wanted.

Fast response on a broken basement window and a leaking frame upstairs. Neat, on time and they explained everything before starting.

Lead-Safe Work Practices

Most older windows have lead paint. We contain the work area, use HEPA vacuums and clean up before we leave.

Window-by-Window Scope

Every estimate lists each window, what it needs and what it costs, so you can phase the work if you want.

Shop and Field Crew

Bench work, welding and stripping happen in our Port Richmond shop; adjustments and glazing happen on site.
