Mold loves water. Picture the airspace of your house with millions of tiny dry parachutists floating aimlessly about, each one hoping to randomly land on a wet patch.
Picture these tiny dry parachutists not flying alone, but each with a dehydrated city on its back. No, they don’t actually HAVE a dry city, but the instant this little floating astronaut is exposed to water then he comes out of suspended animation and zings to life, growing at a furious rate.
Let’s call these tiny dry airborne astronauts what they really are: mold spores. And because they are microscopic, they don’t need much water. To a microscopic spore, humidity is a lot of water. All it takes is some airborne water vapor (otherwise known as humidity) to hydrate a spore, a little yummy cellulose and it begins its life cycle.
Humidity is water intrusion on a vapor level, and it can be all it takes for the mold in your house to amplify into a big problem. It is why mildew loves your bathroom. It is why mold can take root behind the walls where humidity may be trapped, even though you may not find a direct leak.
Keep your bathrooms ventilated with free-flowing dry air. Or else you’ll have to call your friendly neighborhood mold detector and stage an intervention.
