Mold can grow almost anywhere in a home or business if conditions permit. If there is visible growth on painted wall surfaces, property owners should be concerned about what may be growing on the wall’s opposite side. The environment inside the walls of a house drastically can be different from the outside. This could create a perfect haven for mold. If the wall remains wet for a prolonged period, it’s almost guaranteed that the mold growth on the inside will be worse than on the front. At that point, containing the workspace and removing moldy materials, followed by cleaning of salvageable framing, are the best options.
