Mount St. Mary's College, Doheny Mansion

SGH performed a visual survey of the mansion exterior.  We noted the following:

• Wood-framed exterior walls are clad with plaster, ornamental cast plaster, marble, and sheet metal
• Prominent features of the Doheny Mansion are a Tiffany glass dome, numerous wood balconies, and a wooden tower above the main entrance
• The main skylight covers the Tiffany dome, and acrylic skylights are located throughout the low-sloped built-up roofs, pitched clay tile roofs, and at the east entry canopy

For this project, SGH’s work included the following:

• Water tested to confirm leak paths
• Conducted paint adhesion tests
• Documented concealed conditions of the exterior wall construction at exploratory openings construction
• Analyzed exterior plaster in our laboratories
• Recommended immediate and long-term repairs, maintenance, and further testing
• Wrote the exterior walls and roofs portions of the Historic Structures Report
