“A sinkhole forms when the ground underneath the surface erodes — often because water dissolves the rock (like limestone) or washes away soil underground. Eventually, the surface layer can no longer support its weight and suddenly collapses or gradually sinks.
Sinkholes may start small, but their impact is massive and unpredictable. When the ground beneath a property gives way, it can cause severe structural damage, endanger lives, and make a home or building unsafe to occupy. What’s most alarming is that sinkholes often form silently — with no visible warning signs — until the collapse happens.
Sinkholes most often occur in areas with limestone, gypsum, or salt bedrock. Over time, groundwater dissolves these soft rocks, creating underground cavities. When those voids become too large to support the surface, the ground collapses — forming a sinkhole.
Excessive rain or flooding can wash away soil and loosen sediment, speeding up natural erosion. After a storm, water draining into underground spaces can suddenly trigger the collapse of weakened ground.
Leaking sewer, water, or drainage lines can slowly wash away soil beneath the surface. This man-made erosion is one of the most common causes of sinkholes in residential and urban areas.
Excessive pumping of groundwater, excavation, or nearby construction vibrations can destabilize the soil layers and trigger sinkhole activity. Parking lots and paved areas also prevent natural water absorption, increasing pressure underground.
Improper drainage or poorly compacted fill material under driveways, pools, or foundations can cause the ground to settle unevenly — leading to small “subsidence sinkholes” that gradually expand over time.

A sinkhole can open suddenly, swallowing parts of a house, driveway, or yard within seconds. The force of the collapse can crack foundations, tilt walls, and destroy load-bearing supports — often leaving the property unsafe or unrepairable.
Even when the surface looks stable, voids beneath the soil may continue expanding. This makes nearby structures vulnerable to future collapses, creating ongoing safety risks for homeowners and neighboring properties.
Sinkhole activity can cause walls, floors, and ceilings to shift or crack, leading to permanent structural misalignment. Windows and doors stop fitting properly, floors become uneven, and the building may slowly sink over time.
When the ground moves, it can rupture water lines, gas pipes, and electrical systems. These breaks lead to dangerous leaks, contamination, and even fire or explosion risks.
Sinkholes can make a property uninhabitable or extremely costly to repair. Insurance coverage is often limited or denied if the damage isn’t properly documented and proven to result from geological causes. Many homeowners don’t realize how complex — and expensive — sinkhole claims can become.
As the ground beneath a building erodes, it causes uneven settling and stress fractures in the foundation. Cracks may appear in concrete slabs, crawl spaces, or basement walls, signaling that the soil beneath is moving or collapsing.
When sinkholes form under part of a structure, floors can tilt, dip, or separate from walls. This uneven settling puts stress on framing, doors, and windows — making them hard to open or close.
You may see zigzag cracks running along drywall, corners, or near door frames. These result from the home twisting or sinking unevenly as the ground gives way underneath.
Shifting soil can rupture underground water and sewer lines, leading to leaks, flooding, or low water pressure. These breaks not only worsen erosion but can also trigger further sinkhole expansion.
Outside the home, you might notice holes, soft spots, or sudden depressions in the yard or driveway. These are often early signs that the earth below is hollowing out and may eventually collapse.
Doors and windows begin to stick, misalign, or separate from frames. Roof lines may sag, and porches or additions can pull away from the main structure — clear evidence of movement below the surface.
He coordinates with geotechnical experts to document soil instability and structural impact
Every crack, shift, and underground void is photographed, measured, and included in your claim
He handles the technical discussions and challenge any attempt to deny or underpay your coverage
He fights for the maximum payout needed to stabilize, rebuild, or relocate safely if necessary
“Sinkholes often develop quietly underground — but once the ground gives way, the damage can be catastrophic. As your public adjuster, Jerry’s job is to identify the cause, document the loss, and make sure your insurance claim covers the full cost of repair and stabilization.”
