Mold is something that can affect the structure of a home or building and can also bring about negative health issues. So, it’s certainly something that should be addressed and even something to be concerned about. Knowing how mold grows and how it’s affected by elements can help to prevent mold problems and also help to identify how to address it when it is something that becomes an issue. But, did you know that the seasons affect the growth of mold? If you think or know that you have a mold issue in your home or business, knowing about how mold is affected by the seasons can help you to determine the best course of action for mold control.

How Weather Affects Mold

Mold needs an optimal environment for it to grow successfully. It flourishes in dark, moisture environments, which is why it’s typically found in basements, under carpeting, and in drywall. So, many home or business owners may think that mold is most likely to grow in the hotter, more humid months of the year. However, especially in South Florida, humidity is a year-round occurrence. And, even though there may be less humid months, mold that has been growing during the more humid months doesn’t die off during the winter. It just doesn’t continue growing, which is considered dormant mold. Therefore, just because mold may not be growing and has all the elements it needs to flourish, it doesn’t mean that it’s no longer there or a problem.

Furthermore, if mold is growing indoors, there may be an indoor atmosphere that isn’t affected by outside elements. This means that mold is growing due to humidity caused by HVAC units, leaking pipes, or a crack in a window that’s allowing moisture inside. Thus, mold may grow throughout the year inside all year round. So, yes, it’s true that mold doesn’t like less humid and cooler months. But, that doesn’t mean that mold stops growing or dies off. Therefore, mold can be a year-long issue that can be an issue to both the structure of buildings and health any time of the year.

Does Mold Grow During Winter Months?

Mold doesn’t like cold or less humid environments. But, its main source of energy and need for growth is feeding on decaying, organic matter. So, if there is decaying matter, mold can continue to grow, regardless of the time of year and moisture available. Furthermore, decaying matter includes plants. So, if plants die off more during winter months, this provides mold with EVEN MORE decaying matter to live off. So, yes, mold can grow during the winter months. And, relying on the seasons is no way to go about effective mold control.

Tackling Mold During Winter Months

Don’t wait out winter to address mold that’s growing in a home or business. Relying on cooler months isn’t an effective way to address mold issues. Mold that’s in a home or business doesn’t stop affecting your health or the reliability of your building structure just because it’s wintertime. So, if you’ve noticed that mold is growing, it’s something that you should consider addressing as soon as possible, no matter what time of year it is.
