Standard homeowners insurance typically doesn’t cover subsidence — or when the earth beneath your home gradually sinks or shifts — because this type of damage usually falls under an earth movement exclusion.
However, limited coverage may be available through a subsidence insurance endorsement for mine-related damage or through a state program, depending on where you live and what caused the ground movement.
What is subsidence?
Subsidence is the gradual sinking or downward shifting of the ground beneath your home or another structure on your property. As the soil moves, the foundation can settle unevenly, which may lead to cracks, sloping floors, or other structural problems.
Subsidence usually develops over time rather than occurring as a sudden, dramatic event like an earthquake. Common causes include:
-
Soil that expands, contracts, or shifts
-
Changes in moisture levels, including long dry periods or excess water
-
Nearby excavation or construction
-
Old or abandoned underground mines
The exact cause matters because it can affect both the repair approach and whether insurance coverage applies.
Why does subsidence matter for your home?
Subsidence can lead to expensive foundation and structural repairs if the ground beneath your home keeps shifting. It can also make a property harder to sell, especially if buyers are concerned about past damage or future earth movement.
Why standard home insurance doesn't cover subsidence
Home insurance generally covers damage caused by sudden, unexpected events (called perils in the industry), such as fire, wind, or theft. Earth movement is treated differently. Insurers typically exclude it from standard policies because it can cause widespread, catastrophic damage across an entire neighborhood or region at once, making it difficult to price and insure.
This exclusion applies broadly — to sinking or shifting ground, landslides, some types of sinkhole activity, and even earthquakes, despite earthquakes being sudden events. That's why earthquakes require their own earthquake insurance policy rather than falling under standard homeowners coverage. And it's the same reason subsidence typically isn't covered either. It's grouped into this broader "earth movement" category, regardless of how quickly or slowly the ground actually moves.
When you might have coverage for subsidence
Standard homeowners insurance usually excludes subsidence, but specialized coverage may be available depending on the cause and where you live. Options can include:
-
Mine subsidence coverage: In areas with historic underground mining, you may be able to add a mine subsidence endorsement — an optional change to your policy that adds or modifies coverage.
-
State mine subsidence programs: Some states offer insurance programs or funds for damage caused by abandoned underground mines. Eligibility and coverage rules vary by state.
-
Sinkhole coverage: Some states allow homeowners to buy separate sinkhole coverage or add it to an existing policy. This type of coverage is usually limited to qualifying sinkhole damage and may not apply to other types of subsidence.
Because the rules around subsidence and home insurance vary, ask your insurer what types of ground movement are covered by your policy and what’s not — plus which add-on options may be available.
What are the first signs of subsidence?
Early signs of subsidence often show up as changes in your home's structure. Watch for:
-
Cracks in interior or exterior walls, especially around doors and windows
-
Doors and windows that suddenly stick or no longer close properly
-
Floors that look uneven, slope, or seem to be sinking
Not every crack or sticking door means you have subsidence, but new or worsening changes are worth having checked by a professional.
What to do if you suspect subsidence
If you notice signs of ground movement on your property, act quickly. The sooner you understand what’s happening, the easier it is to decide what actions may be needed. Consider the following steps:
-
Document what you see. Take photos of cracks, uneven floors, or sticking doors and windows, and note when you first noticed them and whether they’ve gotten worse.
-
Have the damage evaluated. A structural engineer or qualified foundation specialist can help determine whether subsidence is actually causing the problem and how serious it is.
-
Review your coverage. Contact your insurance company to ask about your policy’s earth movement exclusions and whether any endorsements or other specialized coverage could apply.
Frequently asked questions
Will insurance pay out for subsidence?
Standard homeowners policies usually won't pay out for subsidence damage. It typically falls under the earth movement exclusion. However, you might be covered if you have a mine subsidence endorsement or if you live in a state with a mine subsidence insurance program or fund. Coverage depends on the cause of the damage and your state's rules.
What is the most common type of home damage that insurance doesn't cover?
Gradual damage caused by wear and tear or poor maintenance is one of the most common reasons a homeowner’s claim may not be covered. Insurance is generally meant for unexpected losses, not problems that develop slowly because a roof, foundation, or other part of the home wasn’t maintained. Earth movement is another common exclusion. That can involve subsidence, earthquakes, landslides, and similar ground movement, depending on the policy.
Does home insurance cover damage caused by nearby construction or excavation?
It depends on what caused the damage and the wording of your policy. If nearby construction causes a specific, sudden event that damages your home, some coverage may be available. But ordinary settling or ground movement is often excluded, even when excavation nearby contributed to it. If another property owner or contractor caused the damage, you may need to seek payment from the responsible party or their insurer instead of relying on your own homeowners policy.
How can you protect your home if you live in a subsidence-prone area?
You can't always prevent ground movement, but you can reduce your risk and catch problems early:
-
Watch your foundation for new or worsening cracks
-
Keep gutters and drainage systems directing water away from your home
-
If you're buying or building in a subsidence-prone area, have a structural engineer evaluate the property or site beforehand
