In some Cases, it is more prudent and cost effective to forego the repairs until a full Restoration can be performed. As craftsmen, we have seen too many times that the poorly performed repairs have caused irreversible damage and led to a restoration sooner than if the window had been left alone.
Sometimes when panels are beginning to buckle but the lead has not yet deteriorated to the point where it has lost structural integrity, it is possible to correct these areas of structural failure with various stabilizing procedures. In rare cases, depending upon the type of problem and condition of the window, it is possible to effect positive change while the panel remains in place. More often the panels need to be removed, the developing problem corrected, and the panel reinstalled into its original opening. When the lead in a window is in good enough condition to “handle the handling”, periodic repair and stabilization can forestall the more expensive Historic Restoration until the structural integrity of that window reaches the point where trying to “maintain” it is no longer reasonable.
