Cracks, sagging floors and doors that stop closing can be early signs

Short answer: Common warning signs of a sinkhole include new cracks in walls, floors, pavement or the ground, doors and windows that stop closing properly, sagging or sloping floors, slanting fence posts or trees, rainwater pooling where it never did, and sediment in well water. In Florida, every property policy must cover catastrophic ground cover collapse, but broader sinkhole coverage is optional and must be bought separately.

Warning signs to watch for

Florida sits on limestone that groundwater slowly dissolves, which is why the state has more sinkholes than any other. The Alachua County Environmental Protection Department lists these warning signs:

Slumping, sagging or structural failure of a building.
Slanting fence posts, trees or other objects.
Doors and windows that fail to close properly.
Cracks in walls, floors, pavement and the ground surface.
Rainwater pooling where it never did before, or no longer pooling where it used to.
Sediment in nearby well water.

What Florida insurance covers: two different things

Florida's sinkhole law, Fla. Stat. §627.706, separates two coverages that are often confused.

The gap matters. Settling, cracking and sagging that haven't produced a visible collapse and a condemned building are generally not catastrophic ground cover collapse. Without optional sinkhole coverage, those losses may not be covered. Insurers that offer sinkhole coverage may attach a separate sinkhole deductible of 1%, 2%, 5% or 10% of the dwelling limit.

"Structural damage" has a legal definition

Under §627.706(2)(k), a sinkhole loss requires "structural damage," which the statute defines as one of five specific conditions, such as interior floors sagging beyond set limits, foundation settlement that overstresses primary structural members, walls leaning or buckling, imminent collapse from ground movement, or damage meeting the Florida Building Code's definition of substantial structural damage. Cosmetic cracks alone usually don't qualify.

How a sinkhole claim is handled

Florida sets testing standards for sinkhole investigations (§627.7073) and offers a neutral evaluation program through the Department of Financial Services (§627.7074): the insurer pays the reasonable costs, the result is nonbinding, and the conference is held within 90 days of DFS receiving the request. Report the claim within Florida's deadlines (notice within 1 year of the date of loss under §627.70132) and keep dated photos of every crack and change.

Sinkhole activity is concentrated in west-central Florida; Homeland handles these claims in Tampa, Ocala and Pinellas County.
