How much time does standing water leave in a Hammond basement?
Standing water is the part of the loss with a clock on it. The longer it stands, the deeper it reaches into the floor, the wall and the wood, and the more of the basement has to be opened up before it can dry.
Water that stands for an hour on a bare concrete slab is a small job. The same water sitting overnight against a finished wall, under carpet and behind a bottom shelf is a different job, and the difference shows up in the bill as much as in the drying time. Most basements here were finished at different times, so one room may have vinyl over concrete, another carpet over a plywood subfloor and a third a half-finished wall with paper-faced insulation. Each of those holds water in its own way.
The call is answered 24/7, so the time of day does not decide when the water gets pumped. What helps is an honest answer to two questions: when did the water start, and when did you first see it. Those two answers tell the technician how far to expect the water to have travelled.
Can you pump out a basement yourself before calling?
Sometimes, for clean water from a known source, with the power to the wet area off and the panel dry. For river or sewer water, or water of unknown depth, it is better to leave the pumping to people who can handle it.
A household wet vacuum or a utility pump can move a few inches of clean water, and that is a reasonable step if the power is safe and the water came from a supply line that has been shut. The risk is not the pumping itself. The risk is standing in water near the electrical service, not knowing how deep the floor dips at the far end, and handling water that has been in contact with the river or the ground.
Whatever you do, take photographs before anything is moved, and keep the wet items where they are until the call is made. Those photographs are the first record of the loss, and they are the thing that makes the rest of the claim easier to explain later.
What does extraction include, and what does it leave out?
Extraction removes free water. It does not dry the building, rebuild a floor or repair the source. Those are separate stages, and the call should say which of them is included.
The extraction stage ends when the free water is out and the readings show the water has moved out of the carpet and the pad. Drying starts from there, with air movers and dehumidifiers set for the rooms and the materials. Repairing the broken pipe, the sump or the window well is work for the trade that owns that part of the house, and the technician will say so at the start rather than leave you to find out later.
Extraction also does not decide what to keep. Carpet, pad and some framing take in water in a way that drying alone will not reverse, and the decision to remove them is made after the readings, with the owner present on the call. Nothing is thrown out at the extraction stage on the strength of a guess.
Why do Hammond basements take water so quickly?
Several reasons combine: the river and the storm drains run high together, the ground around the foundation saturates, and older basements have walls and floors that let water in along the joints.
The Little Calumet runs through Hammond and the Munster area, and when it rises the ground beside it is already wet. The 2008 flood showed how quickly water can come up across Lake and Porter counties once the river overtops its banks. The levee and floodwall work that the Army Corps concluded in July 2024 changed the river side of that picture, but a basement still takes water from the rain that falls on its own lot.
The February 2018 storm was the first real test of the walls built after 2008, and the basements that stayed dry were the ones with a working sump and a clear grade away from the foundation. Where those were missing, the water came in through the wall and the floor at the same time, and the extraction had to start there.
