Why is mold on my ceiling?
If mold forms on the ceiling under a duct or register and there's no sign of a roof leak, badly insulated ductwork may be the cause. Warm, moist air condenses and forms water on ducts carrying cold air through the attic or crawl space. The condensation is a sign that the duct is uninsulated or missing a vapor barrier. Eventually the water saturates the insulation and drywall and mold spores (which are everywhere) take root. In cold weather, the reverse happens. Moisture forms anywhere warm air escapes—for instance, at unsealed joints between duct sections. Inspect your ductwork as a test for mold. Learn how to properly insulate your basement rim joists.
What are the two things that mold and mildew have in common?
Though there are thousands of different types of mold and mildew, they all have two things in common: The first is that their mission on Earth is to digest the organic world around them. The second is that they all need moisture so their little digestive enzymes can go to work. There are differences between mold and mildew, but for our purposes, we can call the entire gang mold. Molds are neither plants nor animals. They're microscopic organisms containing enzymes (responsible for digesting and decomposing) and spores (in charge of reproduction). Mold dwells within the fungi kingdom: a realm that includes mushrooms, yeast and other seemingly unsavory characters. But the truth is, these decay organisms aren't unsavory at all. Without them, toppled trees, dead animals and fallen vegetables wouldn't decompose. Our land would get piled higher and higher with dead stuff. We wouldn't have foods and medicines like cheese and penicillin. The problems arise when mold starts chomping away at things we don't want them to—affecting the look, smell and structural integrity of your house.
