Steps to Start Cleaning the Basement Flood

1. Pump Out the Flood Water

When the basement is flooded, inside as well as surrounding as shown in figure-2, do not hurry to pump out. The water in the ground outside push hard against the outside of the basement wall. The water inside the basement pushes right back.

Quick drain will create walls and floors to crack or collapse, that cause serious damage.

Collapse of Basement Due to Sudden Pumping

 To avoid this:

  • After checking the power supply is off, wait till the water is no longer on the to of the ground. Once this is made sure, first step is to pump out the water from the basement. A sump pump can be used to drain the floor water. A wet-dry vacuum method can be used to suction excess water.  
  • Never use a gasoline-powered pump or generators as they create deadly carbon monoxide exhaust fumes. 

2. Ventilate and Dry the Basement

As soon as the pumping is done, the area must be dried and ventilated with 48 hours to prevent issues of mold growth. Drying can be accelerated by using dehumidifier, opening the windows, aerating the space using powerful fans, and air movers.
3. Cleaning the Flooded Basement

Once the area is dried, clean and disinfect the basement contents and structure like walls, foundation floor, drywalls etc. If lot of mold has been developed, it is recommended to discard the drywall and wood items. Never use bleach to clean, use detergents.

The flooded basement cleanup costs between $500 to over $10,000. This is merely dependent on what type of flood water is in the basement ( clean water, gray water or black water), the depth of flooded water, the equipment used to pump water and the drying equipment.
In some situations, pumping and cleaning can be done ourselves, which will give a cost reduction.
