Assessing the Damage
Before beginning repairs, thoroughly inspect the window to determine the extent of the damage. Look for cracked, missing, or broken glass, as well as damaged lead came or supporting frames. Take detailed notes and photographs to guide your repair process and communicate with professionals if needed.

Step-by-Step Repair Process
Removing Damaged Glass
Carefully remove broken glass pieces using pliers, wearing safety gloves. Use a glass cutter if necessary to score and detach stubborn fragments. Keep all shards safely contained for disposal or recycling.
Preparing the Frame
Inspect the lead came or frame for damage. If the frame is intact, proceed to fit new glass. If damaged, carefully remove the old lead or copper foil and clean the frame to ensure a secure fit for the new glass.
Installing New Glass
Cut replacement glass to size, ensuring it fits snugly within the frame. Use flux and solder to re-seal the lead came or copper foil, creating a strong bond. Apply putty or cement around the edges to waterproof and stabilize the window.
Finishing Touches and Preservation
Once the repair is complete, carefully clean the window to remove any excess flux or debris. Consider applying a protective coating to prevent future damage. Regular inspections and gentle cleaning will help preserve the stained glass for years to come.
Safety Tips and Professional Assistance
Always wear protective gear during repairs to prevent injury from glass shards or sharp tools. If damage is extensive or involves structural issues, consult with professional stained glass restorers or conservators. Proper training and experience are essential for delicate and valuable windows.
By following these steps and prioritizing safety, you can restore and preserve the beauty of religious stained glass windows, ensuring they continue to inspire for generations.
