Repair & restoration of historic stained glass.
We perform everything from partial repairs to complete restorations — and we’ll help you determine which course of action your windows truly need.
Returning windows to the way they were meant to be seen.
Chapman Stained Glass specializes in the repair and restoration of stained glass windows.
Complete restoration returns a window to the condition in which it was originally intended to be viewed. Lead came that has stretched and fatigued over a century is replaced, broken glass is mended or matched, and the panel is re-cemented so it’s strong and weathertight for generations to come.
We’re always available to meet with committees, architects and contractors to help determine their stained glass needs, and we work closely with them to assure a quality product within budget.

Seven steps to a complete restoration.
Every stage is performed by hand in our studio.
Document
Every window is photographed and its condition recorded before any work begins.
Remove & disassemble
Panels are carefully removed, then the leaded glass is taken completely apart.
Hand-clean
Each individual piece of glass is cleaned by hand — never with harsh chemicals.
Match & repair
Damaged glass is repaired, or replaced with carefully matched or reproduced glass.
Re-lead
The window is rebuilt with all-new, high-quality lead came.
Re-cement
Weatherproofing cement is worked into the leads to strengthen and seal the panel.
Reinstall
The finished window returns home, viewed as its makers originally intended.

Restoration questions, answered.
How do I know if my windows need restoring or just repair?
Not every window needs a full rebuild. We’ll inspect your windows in person, explain what we see, and recommend either targeted repairs or complete restoration — whichever truly serves the glass and your budget.
How long does a stained glass window last after restoration?
A properly re-leaded and cemented window can be expected to last another 75–100 years, especially when paired with a well-vented protective covering.
Will our building be left with open windows?
No. When panels come to the studio we install temporary weather-tight closures in the openings until the restored windows are reinstalled.
Can you match glass that’s no longer made?
Yes. We source antique and specialty glass, and when an exact match isn’t available we can paint, plate or fabricate a faithful reproduction.
Do you work with architects, committees and contractors?
Absolutely. We regularly meet with building committees, architects and general contractors to define scope, prepare specifications and deliver quality work within budget.
Can a large project be phased?
Yes. Many congregations restore their windows in phases over several years. We’ll help you prioritize the windows at greatest risk first.
