About Old Orange County Courthouse Rehabilitation

The Old Orange County Courthouse Rehabilitation Project included the maintenance and repair of the building’s exterior in a multi-phase project taking almost five years. Following the failure of a stone corbel, an investigative phase was initiated by a preservation architect. Survey of the building identified flaking stone surfaces, cracking and spalled stone and concrete, inadequate reinforcing at window transom stones, and deteriorated decorative friezes. Additionally, laboratory analysis of Arizona sandstone and concrete was completed, and trial repairs and mock-ups were completed during preparation of the bid documents. Scope of work included repairing and repainting of all the historic wood windows, replacing wood windowsills, strengthening the transom stone between windows on the third floor; securing and patching the sandstone facade, repair of the protruding concrete bond beam, patching and repainting the plastered gable; cleaning sandstone and granite, and replacing copper roofing and drain at a decorative stone balcony.
