Can We Have Mold Growth in Winter? 4 Things to Remember


mold growth in winter

Many homeowners think that mold grows only in warm and humid weather. But, mold is an issue that occurs all year round, especially during winter months. The changes in temperature and activity in winter can actually increase the possibility of mold growth. Both outdoor and indoor conditions can cause mold growth in winter.

Learn About Mold Growth in Winter

I. How Do Molds Thrive Indoor

You have probably heard this many times. But let us have a recap of how mold grows. Mold grows in places where there is moisture, food, and warmth. These are the three important components that can allow mold to grow in your home.

The organic materials found in homes like wood or cotton rugs can be a “food” that can give mold energy to grow. The warm condition of your home can also cause mold to grow. Moisture that travels around your home from basements, kitchens, or bathrooms can cause condensation when it touches a cold wall. Depriving mold with these three components can stop it from growing. Taking preventive steps against mold growth in winter can save you from a lot of headaches.

II. What Causes Mold Growth in Winter

During this cold weather, we keep our homes warm by turning up the heat. Using advanced technology and construction, our homes become tightly sealed causing the warm air to stay inside your home. When the air cannot leave your home, moisture can develop and increase your home’s indoor humidity level. This condition allows mold to grow uncontrollably. Changes in relative humidity inside the house can also cause mold growth.

Moreover, fallen leaves that are wet and damp, when piled up can create mold. As much as you want to rake and remove those decaying leaves, doing so can disturb them and they can become airborne.

To know if mold has infested your home, a proper mold remediation procedure has to be taken place.

III. How To Prevent Mold Growth in Winter

With the right conditions, mold spores can spread and grow in homes. However, molds are not always apparent. You will just know that mold has already invaded your home when it has affected the structural condition of your home. That is why preventing mold growth in winter in the first place is crucial.

  • Keep the humidity level low in this cold season. Make sure that it doesn’t go above 40 percent.
  • Instead of wall-to-wall carpeting, use rugs or washable floor surfaces in areas with moisture problems.
  • Repair leaks in your roof or windows as soon as possible.
  • Clean and vacuum regularly to eliminate sources of mold growth.
  • Clothing, books, or paper can be a good source of food for mold. Avoid storing these materials in areas prone to moisture such as your basement.
  • Open windows and doors for better air circulation or use exhaust fans when your bathroom and kitchen are producing moisture, (e.g. taking a hot shower or cooking). Make sure to vent out the exhaust fans outside of your home and not to your attic.
  • Vent out your dryer outdoors as well.
  • Make sure that your gutter and downspouts are working properly to make sure of the proper flow of water.
  • Keep your attic well-ventilated and insulated.
  • Basements are prone to mold growth. In winter, your basement floor and walls can be very cold, causing moisture buildup. Setting a dehumidifier can help in controlling the humidity level of your basement.
  • If you notice water problems in your crawlspace or basement, make sure to address them immediately.
  • Dry off your footwear and other winter clothing before entering your home. Moisture left in these items can cause mold to grow when sits for a long time.

IV. What To Do If Mold Growth in Winter is Apparent

When the growth has affected a large portion of your home, it is best to hire a professional mold remediation company.

Experts say that removing or killing mold on your own can be useless. Regular house cleaners and bleach are too weak to remove mold. Using fungicidal spray can be effective in eradicating mold, but it can be hazardous to your health.

If mold has already spread in your home, into your HVAC system to multiple areas of your wall, or if unexplainable health issues occur, then it’s time to talk to professional mold remediation experts.

Seeking professional help can keep you from any possible health issues and damage.
