Mold Remediation in Westville NJ, Mold is a fungus that comes in various colors (black, white, green, or gray) and shapes. While some molds are visible and even odorous, mold can also grow between walls, under floors and ceilings, or in less accessible spots, such as basements and attics. Mold does best in water-soaked materials (paneling, wallboard, carpet, paint, ceiling tiles, and the like), but can survive in almost any damp location. Mold can grow in houses situated in the desert, and it can grow in homes in hot and humid climes.
