At Tower Hill Insurance, the difference between sinkhole loss and catastrophic ground cover collapse is defined by the severity, timing, and specific triggers of the damage as outlined by Florida law:

• Sinkhole Loss: This coverage focuses on structural damage caused by sinkhole activity directly beneath the building. It is typically triggered by gradual settlement, such as visible foundation settling, cracks in walls/floors, or doors and windows that stick. This is included as standard coverage in Florida but carries a separate deductible, often ranging from 2% to 10% of the dwelling coverage limit.
• Catastrophic Ground Cover Collapse: This is an abrupt and dramatic event. To qualify, the ground must suddenly collapse into a subterranean void, the depression must be clearly visible, and the structure must be rendered uninhabitable. It is not triggered by gradual settling. The deductible for this type of claim is typically a flat dollar amount or a percentage that is often lower than the sinkhole deductible.

Key exclusions for both types of coverage include normal wear and tear, erosion from surface water, and gradual settlement of earth that is unrelated to sinkhole activity. Because these are separate forms of protection with different requirements, Tower Hill requires a professional engineering report to verify the cause of the movement before approving a claim.
