Have you ever wondered what a smell is? It’s a collection of microscopic “stuff” (well, molecules) floating through the air, that enter your nose, hit your olfactory neurons in your nasal passages and transmit a message to your brain, which you perceive as “smell”. Where do these molecules come from? The things around you. What if the things around you are smoke damaged, moldy, or remnants of a hoarding situation? In essence, little pieces of those elements, impurities, are getting inside of you.
Mold is a concern for most homeowners, and even renters. It is especially prevalent in hot, humid areas (like San Diego in the summer time). Most of the mold you deal will is easily visible, but some mold keeps away from your sights. Sometimes your house/building can develop a musty and stale odor that you cannot find the source of. There’s a good chance that this odor is from mold that is hiding from you.
