As we discussed in a previous post, there are a number of factors that mold needs in order to grow and thrive inside of your home. Mold needs a food source, darkness, warmth, oxygen, moisture, and time. Today we will look at some of the causes of mold to help you identify the source of your problem. Contact Yaeger Environmental Services for help with mold remediation and all your other home improvement projects.


Humidity is one of the biggest causes of mold because it provides the moisture necessary for mold to begin growing. If you live in a humid state, or in a location where there is a high level of humidity in the air due to proximity to the ocean or another body of water, then mold could be a frequently recurring problem for you. The problem can be exacerbated when it has rained for several days in a row. Some ways that you might be inadvertently adding to the humidity in your home are: drying clothes indoors on lines or stands, stand-alone or whole-house humidifiers, and inhibiting good ventilation.


Water leaking through pipes or from structural defects in the roof can be a big cause of mold growth in your home. Many times, leaks from roofs happen in the attic or crawl space above your home where you will not be aware of it until it has grown into a much larger problem. Like leaky roofs, leaky pipes may also go undetected for a long period of time, as most of them are inside the walls of your home.


As a kid, you probably learned that condensation is the process of warm water vapor in the air changing into liquid form when it comes into contact with a cooler surface. For example, if you have ever enjoyed an iced beverage on a hot summer day, you have probably noticed the water droplets that form all over the surface of your drinking glass. While this is a cool observation on your drinking glass, it is not a cool circumstance inside your home. If you observe condensation inside the windows of your home, on metal pipes, or on concrete floors in your basement, then you need to find the source of the moisture so that you can prevent this from creating a mold problem in your home.

Some homes have naturally great ventilation. The builder positioned windows and doors in such a way that the home is able to take advantage of breezes and benefit from good airflow. Other homes may not have been built with good ventilation in mind. If your house falls into the second category, then you will have to be more intentional about ensuring that you create good ventilation in your home. One way that you can do this is to open windows as often as you can to take advantage of fresh air from outside. If the weather does not permit this option, then placing floor fans in strategic locations can help to circulate the air inside your home and prevent the stagnation that leads to condensation.
