When Is Mold Season?

Mold can form at any time of year, but there are certain times where it’s more likely to grow. Mold season typically lasts from spring to fall, and it winds down during the winter. Here, we discuss what you can expect during each season:


You get a brief break during the winter from mold, but it’ll start ramping back up in the springtime. This is because all those “spring showers” creates a lot of moisture in the air. This moisture can seep into your home or business, especially in the basement, attic, and crawlspaces.


Summer is perhaps the worst season for mold. This is because much of the U.S., including Kansas City, experience high humidity during the summer. Kitchens and bathrooms are particularly susceptible to these spikes in humidity since they are already high-moisture areas.

Air conditioning can help reduce the humidity in your home or office, but if you suffer from poor ventilation, then moisture can creep into your crawlspaces, attics, and basements.


Fall tends to be wet, but due to the colder weather, it is not as humid as previous months. As such, the air is typically dry and mold growth tends to slow during these months. That doesn’t mean it’s not possible, though. So, always keep an eye out and be sure to have proper ventilation in your home to prevent mold growth.
