Usually not. Many homeowners policies exclude damage from the settling, shrinking, bulging or expansion of foundations, and standard policies don't cover flood or earthquake damage. A crack caused by a sudden event your policy does cover is a different case, so the cause of the crack and the exact wording of your policy decide it.
Why doesn’t homeowners insurance cover most foundation cracks?
Because most foundation cracks come from causes that policies exclude. A report by Connecticut’s Office of Legislative Research notes that policies may exclude losses from the settling, shrinking, bulging, or expansion (opens in a new tab) of foundations, floors, walls and ceilings. Those are exactly the forces that crack concrete.
The same report lists a second common exclusion: hidden defects and defective materials or construction methods (opens in a new tab). A crack that comes from poor concrete or a poor pour can fall under that one instead.
Most foundation cracks also build up slowly. Concrete shrinks as it dries, soil settles under a footing, and wet soil pushes on a wall for years. Wear and tear and gradual deterioration are common exclusions too, so a crack that grew over time is a hard claim to make.
Will homeowners insurance cover a crack from a sudden event?
It can. If a sudden event that your policy covers damages the foundation, the damage can fall under the policy’s dwelling coverage. The cause is what matters, not the crack itself.
That’s why the first question an adjuster asks is what caused the crack and when. A crack that showed up right after a covered event, with photos showing the wall was fine before, is a different claim from a crack that has been widening for years.
Collapse is a special case. The Connecticut report says standard policies generally cover a collapse caused by a sudden and accidental occurrence (opens in a new tab), and define collapse as an abrupt falling down or caving in that leaves the building unusable. Whether a cracked wall that’s still standing meets that definition has been argued in court, as the Connecticut cases below show.
| Cause of the crack | Standard homeowners policy | Where coverage might come from |
|---|---|---|
| Concrete shrinking as it dries | Usually excluded (shrinking) | None needed for a thin crack. Seal it if it leaks |
| Settling or soil movement | Usually excluded (settling, earth movement) | Ask your agent whether any endorsement applies |
| Soil pressure pushing a wall in | Usually excluded (bulging, gradual damage) | Ask your agent. Get an engineer's report on the wall first |
| Flood | Not covered by most homeowners policies | A separate flood policy, which lists foundation walls under building coverage |
| Earthquake | Not covered (California, for one, requires fire following an earthquake to be covered) | A separate earthquake policy |
| Defective concrete or construction | Often excluded (defects, faulty work) | Builder's warranty on a newer house |
| Sudden event the policy covers | Can be covered under dwelling coverage | Your homeowners policy, depending on its wording |
The table is a general pattern, not a promise about any one policy. Policy forms and state rules differ, so the wording in your own policy is what counts.
Does flood or earthquake insurance cover foundation cracks?
They can, if the flood or earthquake caused the crack and you bought the separate policy before it happened. Standard homeowners policies leave out both.
FEMA’s flood program says most homeowners and renters insurance does not cover flood damage (opens in a new tab). A flood policy’s building coverage lists foundation walls, anchorage systems and staircases. Coverage generally starts 30 days after you buy, so it has to be in place before the water rises.
The California Department of Insurance says homeowners, renters and condo policies do not cover damage from earthquakes (opens in a new tab), with one exception: California law requires them to cover fire caused by or following an earthquake. Policies from the California Earthquake Authority offer deductibles of 5% to 25% (opens in a new tab), so check the deductible before you count on a payout for cracks.
What should you check in your policy?
The exclusions section, the definitions and any endorsements. Read them for the specific words below, then ask your agent the questions in writing.
- Find the full policy form. The declarations page lists your coverage limits, but the exclusions are in the policy form itself. Ask your agent for the complete form and any endorsements if you don’t have them.
- Read the exclusions for foundation words. Look for settling, cracking, shrinking, bulging, expansion, earth movement, wear and tear, and defects or faulty construction.
- Read how the policy treats water. Flood, surface water, water below the surface and sudden discharge from plumbing are often handled differently. A crack that leaks is a different question from a crack that water caused.
- Check the collapse section. Note how the policy defines collapse and whether it requires the collapse to be sudden.
- Look for endorsements. Earthquake, earth movement or water backup endorsements change what’s covered. If you don’t have one, ask what it would cover and cost.
- Ask your agent in writing. Describe the crack and its likely cause, and ask which clauses apply. A written answer is easier to rely on than a phone call.
How do you file a claim for foundation damage?
Report it promptly, document the damage and its cause, and protect the house from more damage. Your policy’s “duties after loss” section lists what you must do and by when. Follow it to the letter.
- Photograph everything. Take close photos with a ruler or crack gauge in the frame, plus wide shots that show where each crack is. The crack monitoring guide shows how to mark and date a crack.
- Write down the timeline. Note when you first saw the crack, what happened just before, and any water, sticking doors or new cracks since.
- Get the cause in writing. Coverage turns on the cause, and a structural engineer’s report says what caused the crack and whether the wall is still moving. The engineer vs contractor guide explains who to hire.
- Stop more damage. Clear gutters, extend downspouts and move belongings away from water. Keep receipts for anything you spend.
- Keep the old repair notes. If the crack was sealed before, the date and method help show whether it’s new.
If the claim is denied, read the letter for the clause it cites and any deadline. Deadlines to sue an insurer are set by state law and the policy. In Connecticut, for example, the insurance commissioner directs insurers to state the deadline for bringing suit (opens in a new tab) in every denial letter.
Ask your agent how to appeal, and contact your state’s insurance department if you think the claim was handled unfairly. For a large claim, an attorney who handles insurance disputes can tell you where you stand under your state’s rules.
Can the cause of a foundation crack be disputed?
Yes. The insurer may say the crack is old settling, and you may say a recent event caused it. Policy wording can end up in court.
Connecticut shows how this goes. In a 1987 case, the state Supreme Court read one policy’s collapse coverage to include substantial impairment of structural integrity (opens in a new tab) of a settling, cracked foundation, so the insurer had to pay. Insurers later argued that ruling didn’t apply to newer policy wording, and dozens of homeowners with crumbling foundations sued over denials.
The lesson for everyone else: what your policy says, in its exact words, decides the claim. That’s why dated photos, a monitoring log and an engineer’s report on the cause matter more than how bad the crack looks.
What if your foundation crack isn’t covered?
Then you’re choosing between watching it, sealing it yourself and hiring help, based on the kind of crack. Most foundation cracks are thin shrinkage cracks you can seal yourself. A few are signs of a wall that’s moving, and those need an engineer before anyone repairs them.
- Thin, vertical, stable crack in a poured wall: monitor it, and seal it if it leaks. The foundation crack repair guide covers the DIY fix.
- Horizontal crack, bowing wall, offset edges, a stair-step crack in a block wall, or a crack wider than 1/4 inch: get a structural engineer’s opinion first. The when to worry guide explains each warning sign.
- Not sure what it’ll cost: the foundation crack repair cost guide explains what drives the price of each kind of repair.
If you’re planning to sell, disclosure is a separate question from insurance. The selling and buying guide covers that, and the foundation cracks hub covers every crack type.
Questions
Does house insurance cover cracked foundation repairs after a plumbing leak?
It depends on your policy's wording and on how the leak happened. Policies treat water differently depending on its source and whether the damage was sudden or built up over time. Ask your agent to show you the exact clauses that apply, and get a written answer before you start the repair.
Can my insurer drop me because of a foundation crack?
That depends on your state's rules and your insurer's filed underwriting guidelines. As one example, Connecticut's Insurance Department barred insurers from canceling or refusing to renew (opens in a new tab) a homeowners policy because of a crumbling foundation, a problem specific to that state. Ask your agent, or your state insurance department, what applies to you.
Does insurance cover a foundation crack in a new house?
Homeowners insurance usually doesn't, but your builder's warranty might. The NRMCA says a typical builder warranty requires repair when cracks leak, have measurable vertical displacement, or are wider than 1/8 inch (opens in a new tab). Read your warranty's terms and report the crack to the builder in writing, with dated photos.
Should I fix a small crack myself instead of filing a claim?
For a thin, stable shrinkage crack, there's usually nothing to claim, so repairing it yourself is the normal route. Keep dated photos and receipts in case the cause is ever questioned. The foundation crack repair guide covers which cracks are safe to fix yourself.
