Originally part of a wealthy neighborhood near historic downtown Los Angeles, this home eventually became part of the eastern campus of Mt. St. Mary's College. Clad in sandstone originally quarried near Santa Barbara, it had undergone severe decay and material loss. Sandstone patching and repair with specialty repair mortars provided the means to bring it back to a higher level. This involved creating a mold of a generic pitch-faced sandstone block from an un-deteriorated portion of the facade. This allowed us to recreate accurate and visually consistent replacement units.
