Earthquake insurance for slab foundations
Slab foundations don't have cripple walls to collapse or the sliding risk of raised foundations — making them more structurally stable in earthquakes. Carriers reflect this with a ~0.94x pricing factor versus baseline. But slab doesn't mean immune: masonry chimneys, hillside location, soft soil, and older construction can still generate significant underwriting scrutiny.
What the Best Earthquake wizard captures
The application documents all the details underwriters look for. Gathering the following before applying produces a stronger submission and faster broker review:
- Foundation type: slab-on-grade, post-tension slab, or pier-and-beam hybrid
- Masonry chimney: even on slab homes, unreinforced chimneys are a major risk factor
- Soil and slope: hillside slab homes face different scrutiny than flat-lot slabs
- Year built: pre-1980 slab homes may still have code-non-compliant construction elsewhere
- Water heater strapping and masonry details still relevant
From indication to bindable options
The Best Earthquake Insurance application gives a preliminary annual range anchored to CDI data, then submits a completed Covwell application to Bollinsure for broker review. A licensed California broker reviews your construction, retrofit, and loss details and shops multiple carrier markets to find the best available terms.
The indication is not a bindable quote — final coverage is subject to underwriting, carrier eligibility, and policy terms. But starting with a strong, complete application gives the broker the best possible foundation for market submission.
Ready to submit?
The 5-step application wizard takes approximately 5–8 minutes to complete. It walks through property and applicant details, coverage terms and deductible selection, construction and foundation type, retrofit and loss history, and a review-and-sign step where you can preview the completed PDF before submitting.
Your completed application is reviewed by a licensed broker who follows up — often the same business day — with market options and next steps.
