Methods to Prevent Mold Growth in Cold Temperatures

If you wish to prevent mold growth in cold temperatures, you need to remember that not all molds are the same. Some molds will absolutely thrive in cold temperatures and some cannot grow in them at all. Cold temperatures may not kill mold, but they may make mold growth easier to curb. Here are some ways that you can prevent mold growth in cold temperatures.

Reduce Moisture

Mold may be able to endure cold temperatures, but it is not able to ensure a dry environment. If you can reduce the amount of moisture in your home, you can prevent mold growth.

In order to reduce moisture, you must ensure that your plumbing is not leaky or faulty, and make efforts to reduce unnecessary water use in your home. You should also check your windows for any excess moisture that may have accumulated due to condensation from low temperatures. If you deal with high humidity levels, a quality dehumidifier may help.

Increase Air Circulation

Incapable of growing in areas that have decent air circulation. This is because having good air circulation dries out an environment to a degree at which mold is not able to thrive.

A good way to get air circulation going in your home is to use ceiling fans or any other available fan. There's also a good idea to make sure that you stay on top of swapping out your air vents every couple of months.

Don't forget the bathroom, laundry room, and kitchen. These specific rooms need a little extra care with the help of an exhaust fan.

We're seeing them in bathrooms more these days, but most never follow the advice of having one installed in the laundry room. If you have a hood vent over your cooking area, one is unnecessary as long as it vents to the outside.

Remove Food Sources

You need to remove any source of nutrients that mold can potentially latch onto in your home. The best way to do this is to ensure you regularly and diligently clean your home.

You would be amazed at how much a little inspection and maintenance can do to prevent mold growth in your home.


Mold growth can happen anywhere there is moisture and food for the mold to feed off. The temperature hardly factors into whether or not mold can grow. It can only affect how it grows and at what speed.

With this knowledge, you should be able to protect your home from mold growth, no matter the temperature.
