Disclaimer

Independent site

Walnut Creek Foundation & Retrofit is an independent website that connects homeowners with local foundation and seismic retrofit contractors. We are not a contractor; contractors may pay us for project requests. Verify any license at cslb.ca.gov.

Not affiliated

This site is not affiliated with, endorsed by or acting for the California Residential Mitigation Program (Earthquake Brace + Bolt), the California Earthquake Authority, FEMA, the USGS, or any city, town or county. Apply for programs only through their official websites.

Costs

Cost ranges come from named third-party sources (Angi, HomeGuide, customhome.us, CRMP) and are broad. Real quotes can land below or above them.

Structural and earthquake information

Nothing on this site diagnoses a foundation, predicts slope stability or promises how any building will perform in an earthquake. A retrofit reduces certain risks; it does not make a house earthquake proof.
