Mold and Cold: What You Need to Know

We’ve written and posted many times about mold in the past.

So, by now you probably know that it’s a sneaky fungus that grows given three optimal conditions: a food source, moisture and an ideal temperature (70-90 degrees are most conducive to mold growth, but the spores can thrive anywhere from 32 to 120 degrees).

But as much as you might know about mold, did you know the cold, late fall and winter months can be ideal times for mold to grow in your home?

This may come as a surprise since we know mold likes those warmer temperatures. However, despite the cold air outside and dry air from heating systems inside, certain areas of the house may be more prone to warm, humid air than they would during other times of the year.

Bathrooms and kitchens are two areas that get a lot of hot, steamy air and they may not have the proper ventilation to let that steam out. This can be a particular problem in winter, because you’re less likely to have any windows open when the weather outside is frightful. Mold will take any chance it can get to start growing in that nice, humid environment.

And as the cold air from outside hitting windows and doorways meets hot air from inside the home, condensation will likely develop around those windows and doors. Mold loves to grow where condensation exists.

Another concern with cold weather and mold is that the fungus can and does flourish in dead vegetation (like those leaves that may be covering your yard as we speak!). Even a frost is unlikely to kill mold spores, so when you walk through those dead leaves and then into your house, the spores can hitch a ride on your shoes or clothes. The more spores that make it inside, the more likely you’re going to have a mold problem.

No matter the season, it’s always a good idea to be on the lookout for mold in your home. If you see it growing, you can always count on SERVPRO of West Brown County for help with mold remediation. Call us any time at 920-434-8224.
