Foundation Repair — Common Questions
Real answers to the questions Bay Area homeowners ask us most often. No runaround, no sales pitch.
Signs include cracks wider than 1/4" at corners, doors and windows sticking in frames, visible settling of one corner of the house, and water intrusion in crawl spaces.
A seismic retrofit for a cripple wall home involves bolting the mudsill to the foundation, installing plywood sheathing on the cripple wall studs, and sometimes adding anchor straps at the top of the cripple wall.
Foundation repair caused by settling, soil movement, or seismic damage is typically excluded from standard homeowner policies. Earthquake insurance may cover seismic damage. We recommend checking your policy before assuming coverage.
It depends heavily on the type and extent of work. A basic seismic retrofit typically runs $8,000–$18,000. Pier underpinning for a settling foundation can run $20,000–$80,000+ depending on scope.
