Everything under the sun is perishable - the stained glass as well. Sometimes the windows are being vandalized, sometimes they become corrupted due the environement pollution... Sometomes one piece of glass is broken, sometimes the whole window is damaged. In such a cases a repair, restoration or even reconstructon is needed to bring back the primal splendour. We clean, re-lead, fix broken glass pieces, reinforce the stained glass panels. We repaint glass, when it is needed. Basing on our knowledge of the iconograpy we can reconstruct a totally damaged stained glass object.
