Why does a south Urbana basement hold water after the river drops?
Water that soaks into the ground around a foundation can stay there after the surface has drained. Concrete, block and the soil against them release moisture slowly, so the lower level can stay damp for days after the visible water is gone.
The soil holds water for a long time after a flood, and the foundation wall acts as a slow path for it. When the water table is high, the pressure can push moisture through the wall and up the slab. That is why a basement can feel wet after the flood has gone, even when the floor looks dry.
A technician checks the wall and the slab with readings rather than by eye. A clean-looking surface does not show whether the framing behind it still holds water.
Should I keep the sump pump running after a flood?
A sump that is working and has power should keep running to clear water from the pit, but its discharge should be checked so that it does not drain back toward the foundation. A sump that has failed should be repaired before the drying starts, because it can re-wet the room.
A pump that has been running for hours may be worn, and a failed float can leave the pit filling again without anyone noticing. Listen for the pump and watch the pit during the first visit. The crew will say whether the pump needs attention.
Repairing a pump is plumbing or electrical work, and those trades are outside this line. A technician will tell you what has to be done and who to ask for it.
What should be photographed before cleaning starts?
Photograph the water line, the level on appliances, the damaged items and the outside grade where the water came in. These pictures help an insurer check the loss, and they show the technician where the water was.
Take wide photographs of each room and close ones of the lines and stains. Note the time each photograph was taken. If the water came from a window well or a door, photograph the ground outside as well, because the grade decides how the water arrives.
Do not throw out damaged items before they are photographed and listed. An insurer may ask to see what was lost, and some items are better kept until the claim is settled.
How long will the house be out of use?
There is no fixed time, because drying depends on the structure and on the readings. A technician will say which rooms can be used during drying and which should be kept clear, and will update that with each check.
Some rooms can stay in use if the air movers are placed carefully and the cords are kept out of standing water. Others, such as a basement with equipment running, are better left closed. The crew explains the layout on the first visit.
A house with children, older residents or a pet may need a plan for the drying equipment, which is noisy and warm. Mention these on the phone so the crew can plan the setup.
Who handles repairs after the drying?
Rebuilding the wall, replacing the floor and repairing the foundation or the sump are separate trades. The restoration crew dries and documents the structure, and the repair work goes to the trade that does it.
Once the readings are at the dry goal, the next step is repairs. Those are quoted by the trade that does the work, and they should be quoted only after the structure has been proved dry, since a repair over a wet cavity can hide mold and decay.
The technician will name the kind of work that is needed and the point at which it can begin. The decision about who does the repair is yours.
