When your basement floods, do not enter the water if it could be in contact with electrical outlets, the panel, or appliances — shut off power to the basement first if you can do so safely, or call an electrician or the utility. Once it is safe, identify and stop the water source, remove the water with a pump or wet vacuum, and get wet items out to dry. Because basements trap moisture and flood water is often contaminated, professional drying and disinfection is usually the safest route.
Basement flooding carries a particular danger: water pooling on the floor of a space that often contains the electrical panel, furnace, water heater, and outlets. Treat any flooded basement as an electrical hazard until proven otherwise. If you cannot shut off power to the basement without entering the water, do not go in — call an electrician or your utility company.
Once power is safely off and you can enter, work out where the water came from. Basements flood from many sources: groundwater seeping in during heavy rain, a failed sump pump, a burst pipe, a sewer backup, or water running down from above. The response differs — clean rainwater is one thing, sewage backup is a serious contamination problem that needs professional handling.
Remove the water with a submersible pump or wet/dry vacuum, then focus on drying — basements hold humidity, and concrete and stored belongings stay damp long after the visible water is gone. Fans, dehumidifiers, and good airflow help, but professional-grade equipment dries far more thoroughly.
Finally, think about prevention, since basements that flood once often flood again: a working sump pump with a battery backup, proper grading and gutters that move water away from the foundation, and sealing cracks all help. A restoration company can both dry the current damage and point out why the water got in.

Is it safe to go into a flooded basement?
Not until you are sure there is no electrical hazard. If water may be touching outlets, the panel, or appliances, shut off power first or call an electrician or utility — do not enter the water otherwise.
How do I get water out of a flooded basement?
Use a submersible pump for deep water or a wet/dry vacuum for shallow water, then dry thoroughly with fans and dehumidifiers. Professional equipment dries hidden moisture far better.
Why does my basement keep flooding?
Common causes are groundwater during heavy rain, a failed sump pump, poor drainage around the foundation, or sewer backups. Fixing the underlying cause is key to stopping repeat floods.
