5 Common Winter Mold Questions

It is a common misconception that mold will only exist in a warm environment. Unfortunately, that means the winter months may not be as mold-free as anticipated. If you find yourself with a mold issue this winter, having the necessary information can help you determine how to approach the problem. Learning about mold starts with clearing up the myth about no mold in the cold.

Does mold grow in cold environments?

Yes, mold can grow in the cold. There are different kinds of mold – and some can grow in the winter months. If you consider the interior temperature of your home, typically around 70 degrees, then the season is not as important as you may have thought. With the right temperature for the kind of mold, a source of food, and a bit of moisture, mold can thrive.

Can cold weather kill mold?

If you plan to wait until winter for the freezing temperatures to take care of your warm-weather mold – don’t! The temperature does not affect the life of the mold. In fact, you might think of the cold weather as a freezer – saving it for a later time. When the weather starts to get warm, the mold will begin to grow again. Get rid of mold while it is not growing!

What can be done about mold on windows in the winter?

A single pane window can collect condensation as the cold air outside hits the warm air inside through the glass. Fortunately, well-insulated windows experience far less condensation. However, if moisture is coming in from your windows and soaking into the window-pane or window sill, you will likely have a mold issue. Replacing older windows can be beneficial in this situation. If you are unable to purchase new windows, drying moist areas frequently can help prevent mold growth.

Will mold allergies improve in the colder months?

Although you may experience some relief from seasonal allergies in the winter months, that is not true for mold allergies. When people heat their homes, mold spores within the ducts and similar locations can be sent into the air. For most mold allergies, indoor heating causes symptoms to worsen. Symptoms include:

  • Sneezing
  • Runny nose
  • Watery eyes
  • Coughing
  • Itching

If you find yourself with these symptoms frequently throughout the winter, you may have a mold allergy.

What can be done to prevent mold growth?

There are some tasks that you can do to prevent mold growth within your home. Start with the ventilation in your bathroom. A steamy room collects moisture and heat, creating the perfect breeding ground for mold. You can also keep your home’s humidity level low, fix leaks immediately, and remove any carpet in wet areas (bathroom, kitchen, etc.). It is also a good idea to clean your ducts at the beginning of the season and ensure your filter is changed regularly. Finally, use cleaning products that can kill mold.

Preventing mold is far easier than removing it. Aim for prevention this winter so that you can avoid the hassle of severe mold allergies! Contact our team at Mold Doctors to learn how we can end your difficulties with mold in your home.
