How long does a damp wall take to dry out?

Depending on the intensity of the humidity and the type of wall, it can take a couple of weeks to a few months for the wall to dry completely. If you notice that your walls get wet regularly, you may need to level your walls to avoid this problem and stop moisture-related problems. If walls are especially wet, it can take weeks or even months before they are completely dry. Once dry, be sure to take the necessary steps to ensure that this problem does not reappear. Some areas of the wall may need to be removed and replaced if the water damage is serious enough.
