Homeowners often call us at SERVPRO of North East Chester County to investigate "moldy smells" or "mildew odors," but often the most obvious visual evidence of microbial growth goes unnoticed. Mold comes in many different colors, shapes, and sizes, and can blend into materials such as wood joists if you do not know what you are looking for. That is why we invest in the training and on-going refreshers that our staff undergoes - to stay at the forefront of the battle against moldy, mildewy, unhealthy, unsanitary homes. One of the common locations for mold growth in crawlspaces and attics, such as with this Pottstown, PA home, is lurking under the floor, within the joist system.
