How to Dry Out a Flooded House in Texas

Drying out a flooded house is not a matter of opening the windows and waiting. A flooded house holds water in its walls, floors, and ceilings, and that water does not dry out on its own in any reasonable time. It needs to be removed, and then the structure needs to be dried with air movement and dehumidification, and the drying needs to be checked with moisture readings. That is professional work, and it is the work this guide describes in general terms.

This guide covers what professional drying involves, why fans alone are not enough, what not to do, and when to call. It makes no claim about how long drying will take for any particular house, because that depends on the extent of the water, the materials involved, and the conditions in the house.

Professional drying in general terms

Professional drying, in general terms, follows a sequence: water removal first, then air movement and dehumidification, then checking with moisture readings. The water removal stage takes out the standing water, using pumps and extraction equipment. The drying stage then uses air movers to push dry air across the wet surfaces, and dehumidifiers to pull moisture out of the air so the structure can release the water it has absorbed. The readings are taken at the start and on each follow-up visit, so that the team can see whether the structure is drying as expected.

The drying equipment may be left running in the house for several days, and the team will come back to check the readings and to adjust the equipment if a particular area is not drying. The equipment is placed according to the inspection, which maps where the water has reached and which materials are wet. The drying may be focused on a single room, or it may cover several rooms, and the equipment may be moved as the drying progresses. The aim is to get dry air to the wet materials, wherever they are, and to keep it there until the readings show the structure is dry. Some rooms dry faster than others, so the team moves the equipment as the work goes on, and a room that dries quickly needs less attention than one that stays wet.

Why fans alone are not enough

Fans alone are not enough to dry a flooded house, because a fan moves air but does not remove moisture from it. A fan blowing across a wet surface will help the surface dry, but if the air it is moving is already humid, the moisture has nowhere to go, and the drying stalls. A flooded house has a large amount of moisture in the air as well as in the structure, and that moisture needs to be taken out of the air by a dehumidifier, so that the air stays dry enough to keep drawing moisture out of the walls, floors, and ceilings.

Fans alone also cannot reach the moisture inside a wall cavity, under a floor, or in a ceiling space. The air needs to be directed to those hidden places, and the moisture needs to be measured, not guessed at. A household fan on a wet floor is a small help, but it is not a drying plan, and it is not a substitute for the professional equipment and the readings that go with it. The difference between a fan and a drying plan is the difference between moving air around and actually removing moisture from the structure.

What not to do

There are several things worth avoiding when a house has flooded. Do not enter a flooded building, and do not handle electrics in standing water. Do not use a household vacuum on standing water, and do not try to mop up floodwater yourself, because floodwater is not safe water and it is treated as Category 3, which means it is professional-only. Do not pull up flooring, cut into walls, or remove skirting boards before the inspection, because the pattern of the damage tells the team where the water has been, and stripping things out early can hide that pattern. A wet ceiling can come down without warning, so do not stand under one that is sagging, and do not try to drain it yourself by cutting into it.

Do not switch the electricity back on if it has been turned off, and do not stand under a ceiling that is sagging with water. Do not open windows in the affected rooms and then leave the house, because ventilation on its own does not dry a flooded structure, and it does not make contaminated water safe to be near. Your job in the first hours is to stay safe, stop the flow of water if you can do it safely, protect what is easy to protect, and leave the rest to the team that will carry out the work.

When to call a professional

Call a professional when a house has flooded, when water has reached walls, floors, or ceilings, or when the water is contaminated. A visit covers the inspection, including the places water hides, and then moves to water removal, drying, cleaning, and repair. The earlier the drying begins, the more of the structure and the belongings can usually be saved, because water that sits in a house continues to damage it long after the flood itself has passed.

If you are in the Arlington area, water damage restoration in Arlington follows the same drying process as anywhere else in Texas. For the drying stage itself, structural drying and dehumidification is the service that covers the work, and flood damage cleanup is the service that covers the water the flood left behind.

The drying plan, day by day, in general terms

The drying plan for a flooded house is a sequence rather than a single event, and it helps to understand it in general terms, without a fixed timeline for any particular house. The first day is usually the inspection and the water removal, when the standing water is taken out and the team maps where the water has reached. The days that follow are the drying days, when the air movers and dehumidifiers are running and the team comes back to check the readings, to see whether the structure is drying as expected, and to adjust the equipment if a particular area is holding moisture. The readings are taken on each visit, so that the team can see the pattern over time rather than a single reading on a single day, and the drying continues until the readings show the structure has returned to its normal level.

The number of days the drying takes depends on the extent of the water, the materials involved, and the conditions in the house, and no fixed duration is promised for any particular property, because those factors vary from house to house and from room to room. A small loss in a single room with hard floors may dry quickly, while a large loss that soaked drywall, insulation, and subfloor across several rooms will take considerably longer. What can be said in general terms is that the drying is finished when the readings say it is finished, not when a set number of days has passed, and the repair does not begin until the drying is finished, because repairing over damp materials stores up trouble for later. The plan is the operator's plan, and the operator confirms when the drying is finished for a particular house.

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 Structural Drying & Dehumidification page explains what that service covers, and the flood damage cleanup page explains how flood water is removed and the rooms are dried.

Do not step in standing water near electrical outlets or appliances while you wait, and if water is still coming in, turn off the shut-off valve for that fixture where you can reach it safely.

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 appliances home.
