Bronze Window Restoration by Heritage Steel Window Repair
Bronze windows are some of the longest-lasting windows ever made. They do not rust, but they do tarnish, their seals wear out and their hardware needs adjustment. We clean, refinish and repair bronze windows and doors in homes, churches and commercial buildings.
We also service modern windows and doors with dark bronze finishes: adjusting sliders, renewing seals and fixing leaks at sills and thresholds.
Cleaning and Refinishing
Bronze can be brought back to a warm satin finish or given an even statuary patina, depending on the look you want. We remove old lacquer and grime, refinish the metal and seal it with a protective wax or coating.
Finishes are tested on a small area first so you can approve the color before we do the whole window.
Bronze Window Services
Bronze Doors
Large bronze and bronze-finish doors are heavy and need hinges and rollers set correctly. We re-hang doors that drag, adjust sliders that are hard to move and reseal thresholds so water stays out.
Maintenance
A yearly cleaning and a fresh coat of wax keeps bronze looking even. We offer maintenance visits for owners who want their windows kept in shape.
We serve Philadelphia, the Main Line, Bucks, Chester and Delaware Counties, South Jersey and Wilmington. Related services: metal window repair, casement window repair, double-hung window repair.
Caring for Bronze Windows
Bronze changes color over time, and that is part of its appeal. Left alone, it darkens unevenly, with streaks where water runs. Regular cleaning with a mild soap and a fresh coat of paste wax once or twice a year keeps the finish even and slows tarnish.
Avoid abrasive pads and harsh cleaners, which scratch the patina and leave bright spots. If a window already looks patchy, a professional refinish can bring the whole frame back to one consistent tone.
Bronze windows are common in Main Line estates, church buildings and older commercial lobbies around Philadelphia. Their seals and hardware are often the weak point, and replacing them makes a big difference in drafts and ease of use.
