ARC is a dry rot repair contractor serving San Francisco and Marin. Physical movement of a building or errors in original construction can create cracks which allow water penetration that results in dry rot in walls below the stucco or wood siding of a structure. We expertly remove all damaged wood, install new wood and find the sources that created the problem. We utilize several techniques for wall repair and then apply a breathable elastomeric coating to re-establish the waterproof integrity of the wall without blemishing the building appearance.
