A flooded basement is stressful, but the first few hours matter a lot, both for your safety and for what you can recover. Here is the order to do things.
1. Safety first, before you go down
- Do not enter standing water if power is on in the basement. Water and electricity are a lethal combination. If you can safely reach your main breaker from a dry location, cut power to the basement. If you cannot, stay out and call an electrician or your utility (DTE).
- Watch for gas. If you smell gas, leave and call your utility from outside.
- Wear boots and gloves. Storm and sewer water can carry contaminants.
2. Stop the source if you can
If the water is from a burst pipe or failed water heater, shut off the water supply. If it is storm or sewer water coming in from outside or through a floor drain, there may be nothing to shut off, and the priority shifts to documentation and removal.
3. Document everything before you clean up
This is the step people skip and regret. Before you move or remove anything, take wide and close photos and video of the water level, the damage, and affected belongings. This is what supports both an insurance claim and a municipal claim. If a public sewer backed up, note the date and time.
4. Remove water and dry out fast
- Remove standing water with a pump or wet vac once power is confirmed safe.
- Get air moving: fans, dehumidifiers, open windows if it is dry outside.
- The mold clock is about 48 hours. Porous materials that stay wet past two days (carpet, drywall, padding) usually need to come out rather than be dried.
- Pull soaked drywall and insulation back to dry material; mold grows behind walls you cannot see.
5. Call your insurer, and read the fine print
File promptly. Be aware that whether you are covered depends on the source of the water and your endorsements. See our guide on whether insurance covers basement flooding in Michigan.
6. Make sure it does not happen again
A basement that flooded once will very likely flood again in the next comparable storm unless the underlying cause is fixed. On southeast Michigan's clay soil, the usual culprits are a failed or undersized sump pump, no battery backup, no backwater valve, or poor exterior drainage. A free assessment identifies which one is your problem so you are not repeating this next spring.
