Your Basement Just Flooded. The Next 48 Hours Decide What It Costs You

Few things sink a homeowner's stomach like stepping onto a wet basement floor. When a big storm overwhelms the sewers or a sump pump quits, what happens in the next 48 hours shapes how much damage you're left with.

1. Safety first

• Don't walk into standing water if it could reach outlets, extension cords, appliances or the electrical panel. If you can't safely shut off power, call your utility or an electrician.
• Assume sewer backup water is contaminated. Wear boots and gloves, and keep kids and pets out.
• If you smell gas, leave the house and call your gas utility from outside.

2. Document everything before you clean

Take photos and video of the water level, damaged belongings, walls and flooring before you move or throw anything away. Write down when you discovered the water. This record is the backbone of any insurance claim.

3. Call your insurer quickly

Standard homeowner's policies often don't cover sewer or drain backup unless you added a specific endorsement. Call early either way; your insurer will tell you what's covered and how to proceed.

4. Dry it out fast

The U.S. Environmental Protection Agency advises drying water-damaged areas and items within 24 to 48 hours to help prevent mold growth. That means:

• Removing standing water (pumps, wet vacs or a professional crew)
• Pulling out soaked carpet, padding and cardboard boxes
• Running fans and dehumidifiers continuously
• Checking drywall and insulation, which can wick water well above the visible waterline

5. Know the Michigan sewer claim deadline

If you believe a public sewer system caused the backup, Michigan law generally requires you to give written notice to the responsible government agency within 45 days of discovering the damage. Contact your city or township promptly to ask about its process.

6. Prevent the next one

Sump pump battery backups, backflow valves and regrading soil away from the foundation are common fixes. They're worth discussing with a contractor, and worth mentioning to buyers if you ever sell.
