Water can enter your home in many ways, and not all damage is treated equally by insurance companies. Understanding the different types will help you better present your claim and avoid surprises.
Common types of water damage
-
Sudden or accidental damage (Sudden / Accidental Water Discharge)
Examples: burst pipe, broken water heater, faulty appliance.
- What to do: Turn off the water source immediately; take photos before moving anything; document everything.
-
Overflows or internal flooding (Overflow / Backup / Sewer‑Backup)
This includes water that returns from drains, sewers, sumps, etc. Some policies do not include this by default; additional coverage may be required.
- What to do: find out if you have a “backup endorsement”; document the origin; preserve evidence such as smell, dirt, photos.
-
Damage related to storms, heavy rain, or external weather damage
If the damage is the result of storms, falling trees, or when the wind blows part of the roof off, insurance often covers it if it is included in the contracted risks.
- What to do: report as soon as it is safe to do so; save photos of the weather damage; repair as soon as possible to prevent further damage.
-
Gradual damage or damage due to maintenance (seepage/leaks/wear and tear)
Slow leaks, persistent dampness, old wear and tear on roofs or pipes. Most policies do not cover this type of damage because it is considered a lack of maintenance.
- What to do: maintain regular upkeep; document any inspections that show you were unaware of the problem; act quickly when you discover something.
-
Mold damage resulting from covered or uncovered water
If the water that caused the mold growth was a covered event (burst pipe, storm), you may be covered. Otherwise, the claim may be denied.
- What to do: document evidence of mold; avoid cleaning anything until you have photos; obtain a professional report if possible.
How to prepare so that your insurance provides you with the best coverage
- Read your policy and verify what types of water damage are covered and which are excluded.
- Add optional coverage if you don’t have it (water backup, sewer backup, moisture endorsement).
- Maintain good general maintenance to prevent gradual damage (roofs, pipes, window seals).
- When damage occurs, take photos/videos before moving furniture or cleaning up.
- Use professionals to assess damage and help with documentation (contractors, inspectors).
- Consider hiring a public adjuster if your claim is large, has been denied, or is undervalued.
Frequently asked questions
- Does insurance always cover mold damage after a leak?
Not necessarily. Insurance may cover the damage if the leak was a sudden covered event. If the leak was slow or due to poor maintenance, it will most likely not be covered. - What is an endorsement or additional coverage?
It is an addition to your standard policy that covers specific risks that would otherwise be excluded, such as sewer backup or sump pump failure. - What is the difference between flood insurance and home water damage insurance?
Flood insurance covers water that enters from external sources (rivers, accumulated rain, general flooding). Standard home insurance does not usually cover it. - When should I take action to give my claim the best chance of success?
As soon as it is safe to do so: report it to your insurance company, document the damage, and avoid making major repairs before the inspection if you are going to file a claim.
