There are two options to prevent molding and caulking from cracking during the colder months of the year. During the winter, the relative humidity in homes often drops significantly due to the cold temperatures outdoors. If your home has a furnace/central heat, this can make the air even drier. A low relative humidity can cause wood molding and floor boards to shrink, resulting in visible cracks.

Option 1: To alleviate this issue, you can setup portable humidifiers throughout your home to help maintain a comfortable level of humidity.  

Option 2: To avoid having to setup several humidifiers, you could install one, central humidifier that can be added directly to your central heating system. This option will treat the air supply of your central heating system to help maintain a comfortable level of humidity by utilizing your home’s existing duct work.
