Some areas of the country have a much higher frequency of mold problems than others do. This has a lot to do with the climate, which can turn your home and crawlspace into a welcoming environment for mold growth. You can of course control your house's indoor environment with climate control and humidity control and waterproof your crawlspace to reduce moisture problems beneath the house, but knowing whether your climate makes you susceptible is key to stopping the problem before it starts. Here are four signs that you may need to stave off mold trouble before it comes knocking.
1. Frequent rainfall
Frequent rainfall, such as is present in the Pacific Northwest, can indicate that the climate is a damp one. The more damp days your area has, the more chances there are for mold spores to hit the ground running when they find a damp surface to attach to. And the more often it rains, the more water is likely to be in the air. This is especially likely to be the case in areas where there isn't a lot of hot sun to burn off the moisture after a rainfall (again, the Pacific Northwest is a good example of this, as it's often cloudy there even during the summer).
2. High humidity
High humidity levels overall, such as exist in many parts of the South, can also encourage mold growth. There are many types of mold and mildew that like to grow in human habitations, and they can grow in either warm or cold climates; pretty much any temperature that you can survive in is also hospitable to mold. So both cool dampness (such as you might find in a crawlspace) and warm humidity are situations that mold will like.
3. Lots of surface water
Your microclimate can also influence whether or not your house is a haven for mold. If you live by a lake or near swamps, ponds, or other areas of surface water, this can increase the humidity in your specific region, which again means there's likely to be a lot of mold in your area.
4. Regular storms
Hurricanes, winter storms, or any other storm that can cause water damage to your home is going to bring a lot of mold problems to the area. For example, there are still many homeowners and renters in the New England area today who are having problems with mold that started when Hurricane Sandy came through a few years ago. Often these mold problems had been treated in the past (or simply painted over before the house or apartment was re-sold or rented out), sometimes multiple times, but keep coming back. So if you're moving to an area that's had big storms in recent years, you should be aware that many homes come with pre-existing mold problems.
