Once the mess is cleared up and everything is in order, it's time to start drying out your home. Fans should be used to help with the process, and windows and doors should be opened as much as possible. It can take anywhere from two to four weeks for a house to completely dry out before it can be rebuilt after a flood, depending on the severity of the situation. However, there are some general guidelines that can be used to estimate how long the repair process will take.
Generally, it takes around 72 hours for any affected area to dry out completely, but this only applies from room to room. A small house that has been hit hard by a large amount of water can take longer to repair than a large house that has only suffered minor water damage. One of the most devastating things you can experience is not repairing water damage after a flood or severe water damage to your home. It's important to remember that the size of the house and the amount of water damage it has sustained will both play a role in how long it takes for the house to dry out and be ready for repairs.
