Why does standing water need removing first?
Standing water keeps soaking the materials under it and spreads into dry areas. Removing it first stops the damage from growing, and it lets the crew see the true extent of the wet area.
Water that stands on a floor soaks upward into the wall base and downward into the subfloor. Each hour adds moisture to materials that might otherwise have dried. Extraction stops that growth before the drying begins.
Standing water also hides the true extent of the damage. Once it is removed, the crew can see the wet line and the entry point, and it can plan the work from the readings rather than from the surface water.
What should a homeowner do before the crew arrives?
Turn off power to the affected area if you can do so safely, close the source if you can reach it, and keep people and pets out of the water. Move valuables to a dry area and photograph the water before anything is moved.
Do not enter standing water near outlets or appliances. If the power can be turned off at a panel without standing in water, do so. If not, keep clear and let the crew confirm the power on arrival.
Photograph the water, its depth and the damage from a dry spot. Keep a note of when you first saw the water. Those records help the crew and the insurer.
How does extraction handle the silt and debris?
Silt and debris are removed as they are found, because they clog equipment and hold moisture. The crew records the material it removes, and it notes any unusual smell or color that could point to a different kind of water.
Silt settles into corners and gaps as the water drops, and debris catches on the pumps. The crew clears these as it works, so the equipment keeps running and the floor does not hold moisture under the silt.
An unusual smell or color is a reason to change the approach. The crew treats the water as sewage where it is unsure, and it says so before any further work.
What happens after the water is removed?
After extraction the crew reads the wet area, sets the drying and records the readings. The next steps, such as opening walls or lifting flooring, are explained and approved before they begin.
Once the water is gone, the crew reads the walls, floors and cavities with moisture meters. Those readings set the drying plan and show whether any material must be removed.
The homeowner or manager receives the record and the scope. Nothing beyond extraction proceeds until the next steps have been explained, so the decisions remain with you.
