Mission San Juan Capistrano

Mission San Juan Capistrano, founded in 1776, is the seventh mission established by the Spanish Franciscan friars in Alta California. As the mission moved through different phases of expansion, abandonment, revival, and development, the buildings underwent changes in materials and configuration, suffered deterioration and ruin, and were maintained and preserved using a variety of materials.

ARG Conservation Services was retained by Mission San Juan Capistrano to conduct and manage architectural conservation treatments on masonry in selected areas on the exteriors of the Serra Chapel, Peregrine Chapel, and South Wing of the convento. The treatments—repointing, brick repair, adobe repair, plastering and limewash, plaster conservation, wood conservation, and seismic reinforcements—represent a blend of traditional masonry craftsmanship, structural engineering design, and architectural conservation methods.
