A typical drying time can be 5 days, depending on the extent of the damage and the drying process being used. Also, consider the source of the water damage, what has been affected, and how long the area has been humid. In some cases, the drying time can be done in as little as one or two days or in a maximum of 7 to 10 days. When your drywall is damaged by water, it can be damaged in both the front and the back.
In such a situation, the wall must be open and accessible from both sides to dry sufficiently, which may take a few weeks. Otherwise, it can take months for the drywall to dry completely. In this situation, mold is likely to have since grown on the affected surface. Unfortunately, there is no exact estimate of how long the drying process would take.
But in general, a house damaged by water can dry out for about 5 days. In some cases, it would take as little as two days and sometimes several weeks to dry a house. There are several things to consider when determining how much time should be spent drying a house. It can take up to two to three weeks to completely dry, but you need to start the process within the first 48 hours after water damage.
If you don't speed up the drying time, you risk mold, sagging, or rotting.
