Basement Flooding Emergency: What to Do Right Now (Michigan Guide)

A step-by-step guide for the first hours after your basement floods, from safety to documentation to preventing it from happening again.

Basement Risk Check · Southeast Michigan · Updated June 2026

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

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.

Michigan deadline alert: if a municipal sewer caused the backup, Public Act 222 claims against the city or county usually require written notice within 45 days of the event. Do not wait for cleanup to finish before filing.

4. Remove water and dry out fast

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.
