Rot isn’t just a condition. It’s a living, breathing pack of organisms that can wreak havoc on a home. To evict these unwelcome house guests, you first need to understand how they form.  Rot is a kind of fungus, which opens the door to mold, mildew, staining, and robs wood of its structural integrity.  Sometime the infected wood even has to be completely replaced to prevent it from spreading to the rest of the structure.  If you find rotted wood, be sure to repair it quickly including treating the affected area with a mildicide to avoid damage and protect your home.
