Ihave an 1878 Victorian Home that we are remoldeling and turning into a B&B. I have five stained glass windows in the home. Two of th five need repair. The one in the dining room needs two retangular beveled pieces repalced. The one above the fireplace sets in a split flue chimney. This one needs the lower section flatted all the glass is in tack. All the windows have support rods going across them. I have contacted two repair specialist and each one states they would remove the support rods and sandwich them between glass. This will not work avobe the fireplace because, the center medalion is concave. Does removing the support rods and sandwiching the glass affect the value of the window.
