Mold is a serious concern for you and your home, not just because of the damage that it can cause to the structure of your house, but because of the health concerns that it can cause for you and your family. Mold is particularly meddlesome because it can be hard to identify, tending to grow in darker and damper areas that are out of the general line of sight of your everyday routine. Knowing the most likely places where mold may grow out of sight can help you know where to check if you start noticing a musty smell in your house.
Behind the Walls
The most common place for mold that is caused by a roofing or plumbing leak is behind the walls of your house. Due to the sealed nature of this area, it can be hard for the odor to start being noticeable in the rest of your home until the mold has become well established. Eventually, mold will begin to eat its way through the surface of your wall, becoming visible on the other side. Fortunately, you can tell if there is mold growing behind your walls by keeping a close eye on the wallpaper and paint. Since mold needs a fairly significant amount of humidity to grow, moisture damage will almost always seep through your wall before the mold does. This moisture will cause your wallpaper and paint to bubble, warp, or otherwise peel away from your wall, revealing the progressing problem underneath.
Under the Carpet
Another hidden place that mold loves to take root in, but which is fortunately much easier to check than the above point, is in the padding of your carpet. This can occur over time due to general humidity in the air, or because of a few spills that were not cleaned up quickly enough. All you have to do to check your carpet is flip it over to see if the padding has become stained a green or black color. Your mold problem can also be solved fairly easily just by throwing the carpet out as soon as possible. Quick disposal of the carpet may thwart the need for additional mold removal services.
Fridge Drip Pans
The drip pan underneath your fridge serves as a place for condensation from the cooling fins to fall without damaging the floor under the appliance, but the dark and naturally damp nature of this pan makes it a prime breeding ground for mold spores. You can usually check the drip pan by taking off the kick panel on the front of your fridge and sliding it out, but check your owner's manual for specialized instructions. You can clean out the drip pan using a mixture of bleach and water, or vinegar if you want a natural cleaning solution.
