Does homeowners insurance cover basement or crawl space water damage?

We are waterproofers, not insurance agents, and every policy is different. This is the pattern we see on Louisville jobs. Read your own policy and ask your agent; the words below will help you ask the right questions.

Usually covered: sudden and accidental, from inside

Standard homeowners policies are built around sudden, accidental events. A pipe bursts, a water heater lets go, a washing machine hose fails, an upstairs tub overflows. The water damage to the basement, its contents and the finishes is typically covered, minus the deductible. The failed pipe or appliance itself often is not; the policy pays for what the water ruined, not for the part that broke.

Usually not covered: water from the ground or the sky

• Groundwater seepage through walls, floors and the cove joint, which is the most common wet basement in Louisville, is excluded on most standard policies.
• Surface water and flooding, meaning rain running in from outside, creek or river flooding, or water pooling against the house, is excluded and only covered by a separate flood policy through the National Flood Insurance Program or a private flood carrier.
• Sewer and drain backup, including a sump pump failing, is excluded unless you added a water backup or sump pump overflow endorsement. It is inexpensive and worth asking for.
• Gradual leaks and long-term moisture, including mold from a damp crawl space, are treated as maintenance and excluded almost everywhere.

Damage versus cause

Even when a loss is covered, the policy pays to repair the damage: drying, tearing out and replacing finishes, replacing contents. It does not pay to make the basement waterproof so it does not happen again. That work, the drainage, the sump, the wall system, is on the homeowner. This surprises people after a covered sump failure: the carpet is paid for, the battery backup is not.

How to give a claim its best chance

1. Photograph and video everything before you move it: the water line, the source, each damaged item, the serial plates on ruined appliances.
2. Call the insurer the same day. Most policies require prompt notice, and a delay that lets mold grow can be used to reduce or deny the claim.
3. Stop the damage from getting worse. Policies require you to mitigate: shut the water off, get the water out, start drying. Keep receipts for pumps, fans and dehumidifier rentals; they are usually reimbursable.
4. Keep the ruined material until the adjuster has seen it or has told you in writing it can go. Bag it, list it, photograph the bags.
5. Get the cause in writing from whoever fixes it. A plumber's invoice that says “burst supply line” is the document the adjuster wants.

The endorsements worth asking your agent about

• Water backup / sump overflow: covers sewer backups and sump pump failures. Usually a small annual cost.
• Flood insurance: the only thing that covers surface and river flooding. Required in mapped flood zones, available almost anywhere, and in Louisville the low-lying areas near the river, Beargrass Creek and the Salt River are the ones to think about.
• Service line coverage: the water and sewer lines between the street and the house, which are otherwise yours to repair.

Where that leaves a wet basement

For most Louisville homeowners with a basement that seeps after heavy rain, insurance is not the answer and never was. The answer is fixing the drainage so it stops. The cost guide has typical ranges, and the inspection and written price are free, so you can decide with real numbers rather than a hope about the policy.
