How to Dry Out a Flooded House in Louisiana
Drying out a flooded house is not a matter of opening the windows and running a few fans. A flooded house is soaked through: the floors, the walls, the ceilings, the insulation and the subflooring have all taken up water, and the water inside the structure is far more than the water that was on the floor. Drying it properly is a measured, professional process, and this guide explains what that process looks like in general terms.

It also explains why fans alone are not enough, what not to do, and when to call a professional. It does not advise entering a flooded building, and it does not give do-it-yourself drying instructions for a flooded house. Homeowners in Lake Charles and Monroe face the same drying question, and the flood damage cleanup page explains the professional cleanup sequence in general terms.
Professional drying in general terms
Professional drying starts with an inspection, then water removal, then drying itself, using air movement and dehumidification, with progress checked by moisture readings rather than by touch or by eye. The inspection finds where the water has gone, including into walls, under floors and above ceilings, and the drying is arranged around what it finds. Drying equipment is placed where it will do the most work, and the readings are checked over successive visits to confirm the structure is drying as expected.
Some materials cannot be dried and need to be removed instead: soaked drywall, saturated insulation and carpet that has been in floodwater are common examples, and that decision is made from what the inspection and the readings show. Cleaning and repair follow once the structure is dry. The structural drying and dehumidification page explains the drying step in general terms, and the water damage restoration page lays out the full sequence.
Why fans alone are not enough in general terms
Fans alone move air, but they do not remove moisture from the air, and in humid conditions they can move moist air around without drying anything. As fans push air across a wet surface, the air takes up moisture, and the more moisture it takes up, the less it can take. In a closed room, the air soon becomes saturated, and the drying stops, even though the fans are still running. Dehumidification removes that limit by taking the moisture out of the air as fast as the air takes it up from the structure.
Louisiana's humidity makes this especially relevant in general terms, because the air outside the house is often already moist, and opening windows can bring more moisture in rather than letting it out. That is why drying is a controlled process, with the house closed up and dehumidification doing the work, rather than a matter of opening windows and running fans. A house dried by fans alone, without dehumidification and without readings, is a house that may still be wet where it matters, and the moisture left behind can lead to further damage over time.

What not to do
Do not enter a flooded building. Do not wade through floodwater, and do not try to dry a flooded house yourself. Floodwater is contaminated water, and cleanup is professional-only work. Do not use household fans, heaters or vacuums in a flooded house, and do not use any electrical equipment in or near standing water. Do not open walls or lift flooring to look for the water, and do not throw things away before they have been photographed, unless a professional tells you to discard something that is a clear health hazard.
Do not assume the house is dry because the water has gone from the floor. The water that was on the floor is only part of the loss. The water inside the structure is still there, and it needs the professional drying process to remove it. Do not paint over stains, do not cover damp patches, and do not move wet items into dry rooms. Keep everyone out of the flooded areas until a professional has checked the property, and follow the instructions of the authorities about when it is safe to return.
When to call
Call a flood damage restoration professional once the water has receded and it is safe to enter the property. Describe what happened in plain terms: how high the water reached, which rooms were affected, how long the water was in the house, and what you can see now that it has receded. A professional visit generally starts with an inspection, then removal of any remaining water, then drying, cleaning and repair. Floodwater is treated as contaminated water throughout, so the cleanup is professional-only work, and the sequence is shaped by what the inspection finds.
While you wait, keep the house ventilated if it is safe to do so, keep everyone out of rooms that are still wet or damaged, and take photographs of every room before anything is moved. For homes in New Orleans and Baton Rouge, as across Louisiana, the first steps are the same: safety first, do not enter until it is safe, and call a professional. The house can be dried and repaired, but only in the right order, and only once it is safe to work in. The emergency water removal page describes the removal step that comes first.
The rooms that dry last
Some rooms dry last, and it helps to know which ones, so the work makes sense as it progresses. Rooms with water trapped inside wall cavities dry slowly, because the air cannot reach the cavity easily. Rooms with water under flooring dry slowly, because the flooring blocks the air. Rooms with saturated insulation dry slowly, because the insulation holds the moisture and releases it gradually. Bathrooms and kitchens often dry last, because they have the most enclosed spaces: the wall behind the bath, the floor under the dishwasher, the cavity behind the kitchen units. A room that looks dry on the surface can still be wet inside, and it is the last to be confirmed dry.
That is why the readings are taken in the materials themselves, and why the professional visits more than once. A house is not dry when the first room is dry. It is dry when every affected room is dry, as shown by the readings. For homes in New Orleans and Baton Rouge, the structural drying and dehumidification page explains the drying step in general terms, and the rooms that dry last are the ones that decide when the job is finished.

Questions About How to Dry Out a Flooded House in Louisiana
How is a flooded house dried out?
By a professional process: inspection, water removal, then drying with air movement and dehumidification, with progress checked by moisture readings. Some materials, such as soaked drywall and saturated insulation, may need to be removed rather than dried. Cleaning and repair follow once the structure is dry.
Why are fans alone not enough to dry a flooded house?
Fans move air but do not remove moisture from it. In humid conditions the air soon becomes saturated and drying stops. Dehumidification takes the moisture out of the air so the air can keep taking it up from the structure. Fans and dehumidifiers are partners, not substitutes.
Can I dry out a flooded house myself?
No. Floodwater is contaminated water, and cleanup and drying are professional-only work. Do not enter a flooded building, do not use household equipment in standing water, and call a professional once the water has receded and it is safe to enter.
How do I know when a flooded house is dry?
By moisture readings taken in the walls, floors and ceilings, compared over successive visits. Drying is finished when the readings in the affected areas are close to those in unaffected areas and stable. A surface that feels dry is not proof on its own.
Your Next Step
If this guide matches what you found at home, the next step is a visit — not a guess. Call and describe what you found, and the visit is arranged from what you describe. The Emergency Water Removal page explains what that service covers, and the water damage restoration page explains how the full sequence works when water has reached more than one room.
Do not enter flooded rooms while you wait, and if water is leaking, turn off the shut-off valve for that fixture where you can reach it safely from dry ground.
Keep the guides on this site bookmarked: the first guide, the signs guide, and the preparation guide cover the checks worth repeating — after moving in, and after bringing used fixtures home.
Water damage help is available across Louisiana. See water damage restoration in Napoleonville, LA for one local example, or find your town on the service areas page.
