Wisconsin basements flood for all kinds of reasons: spring thaw, heavy summer storms, a failed sump pump, or a sewer backup. The first 48 hours make a big difference in how much you can save and how much it costs to fix. Here's what to do, step by step.

1. Make It Safe First

Stay out of standing water if outlets, cords, or appliances are underwater. Shut off power to the basement at the breaker panel only if you can reach it while standing somewhere dry. If not, call your utility or an electrician.
Smell gas? Leave the house and call your gas utility from outside.
Sewer backup? Treat the water as contaminated. Wear boots and gloves, keep kids and pets out, and wash up after any contact.

2. Document Everything and Call Your Insurance

Before you move or throw anything out, take photos and video of the water line, damaged walls, flooring, and belongings. Then call your insurance company. Many Wisconsin homeowner policies treat sewer and drain backup as a separate add-on, and flooding from outside water is usually only covered by flood insurance, so ask exactly what's covered before work starts. Keep receipts for everything.

3. Get the Water Out

Small amounts of water can be handled with a wet-dry vac and a working sump pump. For several inches of water, a sewage backup, or water that keeps coming back, call a water restoration company or a plumber. They have pumps, moisture meters, and commercial drying equipment.

4. Remove Wet Materials Within 24–48 Hours

Mold can start growing on wet materials in as little as 24 to 48 hours. Anything soaked that can't be dried quickly should come out of the basement. That usually includes:

Wet carpet and carpet pad (pad almost always has to go)
Drywall and insulation below the water line, usually cut about 1–2 feet above where the water reached
Particleboard furniture, cardboard boxes, and paper
Mattresses, upholstered furniture, and stuffed items
Anything touched by sewage that can't be cleaned and disinfected

Concrete floors, solid wood, metal, glass, and many plastics can often be cleaned, dried, and kept.

5. Dry Out the Space

Run dehumidifiers and fans, open the space up, and keep it going until everything is truly dry, not just dry to the touch. A restoration company can confirm with a moisture meter before you rebuild.

6. Prevent the Next One

Test your sump pump each spring and consider a battery backup
Extend downspouts several feet away from the foundation
Make sure soil slopes away from the house
Ask a plumber about a backwater valve if your area has had sewer backups
Store basement items on shelves or in plastic bins instead of cardboard
