  • Cracks and Breaks: Visible cracks in the glass pieces or broken elements indicate structural damage from impact, stress, or load.
  • Paint Loss: Fading artwork can be caused by insufficient kiln firing of glass, glass incompatibility and paint composition. Flaking, fading and Accreations of dirt can visually impact the legibility of a window. Weather and condensation can exacerbate this condition.
  • Bowing or Buckling: A window moving out of plane can be caused by poor design, improper fit into the opening, hard-setting putty and/or insufficient support system.
  • Lead Fatigue: Lead cames that hold glass pieces together may weaken by repeated stress from the expansion and contraction cycles and/or the flexing of the window due to wind or loading. These forces can cause fatigue and risk structural integrity.
