What is the difference between extraction and drying?
Extraction removes the standing water. Drying removes the moisture that has soaked into materials after the water is gone. Extraction is quick, while drying takes days because moisture inside wood and drywall leaves slowly and needs airflow and dehumidification to be pulled out.
Once the visible water is gone, the materials still hold water in their structure. Carpet pad and insulation can stay saturated long after the floor looks clean, and the air in the room can be humid enough to slow the rest of the drying. Extraction is the first stage, and the drying plan is the second stage that proves the building is dry.
A crew that stops at extraction has removed the water but not the moisture. Ask the technician to show you the readings after the extraction, so you can see how much moisture remains and where it is. That number tells you how long the drying will take.
Should I use my own pump or wet vacuum before the crew arrives?
A small wet vacuum can help with a little water on a hard floor, if it is safe to use and the power is off in that room. Do not use one in standing water, near a wet panel or on a carpet that is saturated, because the water can reach the motor and the outlet.
If a few gallons of clean water have spread across a tile or vinyl floor, you can soak it up with towels and wring them out into a bucket. A household vacuum is not designed for water and can short out or spread contamination. Do not run one through water at all.
A rented or household pump is not a substitute for a crew that can measure the building afterward. Even if the visible water is gone, the materials under it may still be wet, and only readings show whether the cleanup is complete.
What happens to a cellar after the water is pumped out?
The cellar is checked for moisture along the walls, the floor and the sill plate, and the mechanical equipment is inspected before it is used again. Drying equipment is set to pull the moisture out of the cellar air and the lower wall.
Cellars often hold water in the bottom of the wall, behind the stored items and under the stairs. The crew measures these areas and records the readings. The water heater, the furnace and the electrical panel are checked before they are turned back on, because they can be damaged by standing water.
A cellar can stay humid for a long time after the water is removed. The drying plan usually includes a dehumidifier that runs until the readings show the cellar and its materials have dried, and the crew explains what it will cost to keep it running, without giving a price over the phone.
What should I do with belongings that were in the water?
Move items out of the wet area if it is safe, photograph them, and keep them away from clean rooms. Items that were in clean water may be dried, while items that were in contaminated water are often discarded, and the technician will explain which is which.
Photographs made before anything is moved are useful for an insurance claim, so take them first. Keep a list of what was damaged, its age and its approximate value, because the insurer will ask about it. Do not try to clean upholstered furniture or rugs that have been in dirty water without advice.
Papers, photographs and electronics that were wet should be set aside for the technician to see. Some can be dried if they were in clean water and handled quickly. Others are better left to a specialist, and the crew will say so.
