This bathroom had a small leak and once we checked for mold presence, we found mold growth within the walls. This happens a lot because water usually seep through the walls and can promote mold growth. If you notice a musty odor in your home, you probably have mold growing there, even if you don't see any mold. But don't worry, call SERVPRO of Alhambra at (626)283-5875 and we can help you find the source of the odor!
