Four Common Causes of Mold

Most people think the most common cause of mold in their home is from flooding and the water damage it leaves behind.

And, yes, that is one of the most common ways people find out they have a mold issue. But, flooding isn’t one of the most common causes of mold damage to your home.

In fact, there are many various causes for mold in your home that you may not know about or even realize.


When the air carries heavy humidity for several days in a row, it’s basically carrying excess water that it’s looking to get rid of. Often humidity can leave exterior walls, furniture and other surfaces feeling wet. That wetness can cause mold growth.

Home humidifiers set too high can also cause mold growth, as some types of mold can grow when the humidity is higher than 70 percent. If you’re using a humidifier in your home during a very dry time of year, make sure to still keep it below that percentage to avoid mold growth on surfaces near the system.


Cold surfaces in a warm environment can cause condensation that leads to mold. Some examples of this include concrete floors, metal pipes, and even glass surfaces. If there are places in your home that regularly collect condensation, make sure to check them on a regular basis to ensure there’s no mold growth.

Poor Ventilation

If even one area of your home has poor ventilation, it’s a cause for concern. Air can only escape when properly ventilated, and poor ventilation causes the air to get trapped and create humidity, which as we already know causes mold to grow.


Water leaks, whether from leaky pipes or from your roof, can be one of the worst causes of mold. This is because these leaks often go undetected inside a wall or the ceiling of your home for an extended period of time.

It’s likely that by the time a leak is detected, there’s already mold growth that needs to be removed.
