Alternate Method of Wall Restoration Without Removal of Exterior Finish

Presented by Brett M. Ferrari, SE

Ferrari Moe, LLP - San Rafael, CA

A large single family, stucco home in Marin County had incurred severe wood decay in the framing members of the front garage wall. There is a two car garage with patio and structure on top of it. The wall was framed with 2x8 studs and sheathed with plywood on both sides. A portion of the wall was used as a shear wall for resisting lateral forces. The amount of decay was so severe that the wall needed to be completely demolished and reconstructed. The owner did not want to lose the ivy growth on the front of the garage, so we devised an alternate repair method that entailed replacing all of the framing and sheathing from the back side, without removal of the exterior stucco finish. Except for the door frames, no organic materials remained in the wall at the end of the restoration. Fiberglass cloth was epoxied onto the back of the stucco and steel studs were installed to brace the wall. A two-bay steel moment frame was also installed to take the place of the shear wall. All of the work was performed without cracking the stucco wall or disturbing the ivy.
