Because mold is a sneaky type of growth that doesn't give off a lot of warning that it's taking over your house, it's important to not only maintain a clean, dry atmosphere in your house so it's less likely to get started but also to inspect frequently those areas in your home that are more likely to become infested. Here are three places to inspect for mold development.
Running the bathroom fan each time you shower is a good place to start, but to keep your bathrooms free of mold, you'll need to take a quick look around every once in a while at the spots that are most likely to harbor mold. For example, a wet shower curtain is one of the top places for mildew to grow, so airing the curtain out each day (instead of leaving it crumpled up after showering) and cleaning it regularly are essential. And even in bathrooms that may not be used as frequently, you should check under the sink and behind the toilet for any signs of moisture. Condensation on the back of the toilet can create a humid micro-climate favorable to mold, and even a slow drip under the sink can do the same. Be sure to check under your kitchen sink as well while you're at it.
2. Laundry or mudroom
If your dryer has an air leak and allows humid, warm air to escape inside your laundry room, you could have a breeding ground for mold on your hands. And since the washer is usually wet inside, mold and mildew can actually grow in the crevices inside it. Be sure to check in other damp spots as well, such as where people leave their wet shoes in the winter.
3. Basement or crawlspace
Basements, especially unfinished basements, tend to be quite damp. If yours has high humidity, you may wish to consider using a dehumidifier on a regular basis to discourage mold growth. You should also check the drainage around your house; if your house is on a hill and water from the hill above drains down toward your basement, it may be impossible to keep your living space dry and mold-free without improving the drainage situation. Check that gutter drainage is directed away from the house as well; you don't want to have all the water from your roof dumping straight down towards your basement.
These three spots are some of the most likely spots in your house to develop mold. Because they can develop their own micro-climates, it may not be enough to simply run a dehumidifier in each room without addressing the trouble spots as well. Small electric fans can help improve air circulation under sinks, and improving drainage can help keep moisture from entering your basement.
