Catastrophic Ground Collapse — the strict 4-test trigger
Catastrophic Ground Collapse — the strict 4-test trigger. For Florida policyholders this comes up almost every renewal, and the right answer depends on your address, prior claims and which carriers are still writing your risk profile in 2026. In our day-to-day book of business across Cape Coral, Fort Myers, Port Charlotte and Naples, this is one of the levers that consistently moves real dollars.
The practical move: have a licensed agent walk your declarations page line by line and tell you which carriers in today's market would price your specific home, vehicle or business better — and which would decline. Re-shopping every renewal is the difference between a stale policy and a competitive one.
