Material Options

Material prices below are national averages; availability in Sacramento may shift costs slightly.

Material	Cost/Unit	Pros	Cons	Best For
Standard Cripple Wall Retrofit (Plywood Sheathing + Bolts)	$3,000-$7,000 per project	Most common method, well-understood by contractors, meets code requirements, proven effectiveness	Requires crawl space access, plywood may limit future changes, not effective on post-and-pier foundations	Homes with cripple walls built before 1980Most common method, well-understood by contractors, meets code requirements, proven effectiveness
Anchor Bolt Installation Only	$1,500-$4,000 per project	Less invasive, lower cost, effective for homes already with continuous perimeter foundations	Does not address cripple wall weakness, may not meet current seismic code in high-risk zones	Homes on concrete perimeter foundations that lack anchor boltsLess invasive, lower cost, effective for homes already with continuous perimeter foundations
Advanced Framing Connectors (Simpson Strong-Tie System)	$4,000-$10,000 per project	High-performance hardware, engineered connections, used for complex or high-value homes	Higher material cost, requires experienced installer, may need engineer design	High-value homes, soft-story structures, or homes with unusual configurationsHigh-performance hardware, engineered connections, used for complex or high-value homes
Post-and-Pier Foundation Strengthening	$5,000-$20,000 per project	Converts vulnerable pier system to continuous perimeter, dramatically improves seismic performance	Expensive, invasive, may require grading and excavation, longer timeline	Pre-1940 homes in high-seismic zones with post-and-pier foundationsConverts vulnerable pier system to continuous perimeter, dramatically improves seismic performance
